  SHARES OFFERED: Units of beneficial interest ("Shares") of the Money Market
Fund, the Diversified Equity Fund, the Income Equity Fund, the Special Equity
Fund, the Income Fund and the Intermediate Tax-Free Fund, six separate
investment funds (collectively, the "Funds") of The Sessions Group, an Ohio
business trust (the "Group").
 
  OFFERING PRICE: The public offering price of the Money Market Fund is equal to
the net asset value per share which such Fund will seek to maintain at $1.00 per
Share. The public offering price of each of the other Funds is equal to the net
asset value per share plus a sales charge of 5.00% (with respect to the
Diversified Equity, Income Equity and Special Equity Funds) and 4.00% (with
respect to the Income and Intermediate Tax-Free Funds) of the public offering
price, reduced on investments of $50,000 or more (See "HOW TO PURCHASE AND
REDEEM SHARES--Sales Charges"). Under certain circumstances, the sales charge
may be eliminated (See "HOW TO PURCHASE AND REDEEM SHARES--Sales Charge
Waivers").
 
  MINIMUM PURCHASE: $1,000 minimum initial investment with $25 minimum
subsequent investments. Such minimum initial investment is reduced for investors
using the Auto Invest Plan described herein and for employees of the Adviser or
one of its affiliates.

investment company.
 
  INVESTMENT OBJECTIVES: For the MONEY MARKET FUND, current income with
liquidity and stability of principal.
 
  For the DIVERSIFIED EQUITY FUND and the SPECIAL EQUITY FUND, capital
appreciation.
 
  For the INCOME EQUITY FUND, capital appreciation with current income as a
secondary objective.
 
  For the INCOME FUND, current income consistent with preservation of capital.
 
  For the INTERMEDIATE TAX-FREE FUND, current income which is exempt from
federal income tax consistent with preservation of capital.

will invest as fully as possible, but in no event less than 80%, of its total
assets in the U.S. Treasury bills, notes and bonds, and repurchase agreements
secured by such obligations.
 
  Under normal market conditions, the DIVERSIFIED EQUITY FUND will invest
substantially all, but in no event less than 65%, of its total assets in common
stocks and securities convertible into common stocks--of that amount 25% to 40%
will be committed to each of the following styles, representing the three
different styles of the SubAdvisers: (1) investing in companies believed to have
strong value measures whose stock is traded at a price below its perceived
value, (2) investing in companies believed to have growth potential, and (3)
investing in companies believed to be in a position to take advantage of
political, economic, industrial or secular trends or developments.
    
  Under normal market conditions, the INCOME EQUITY FUND will invest
substantially all, but in no event less than 65%, of its total assets in common
stocks and securities convertible into common stocks.

ranging on average between $50 million and $1.5 billion and which are considered
to have growth potential.

the various States of the United States or any county, political subdivision or
municipality thereof, including any agency, board, authority or commission of
any of the foregoing, and debt obligations issued by the Government of Puerto
Rico, which generate interest income which is exempt from federal income taxes
and is not treated as a preference item for certain Shareholders for purposes of
the federal alternative minimum tax. The Intermediate Tax-Free Fund, under
normal market conditions, expects to maintain an average weighted portfolio
maturity of four to eight years.
 
  RISK FACTORS AND SPECIAL CONSIDERATIONS: An investment in any of the Funds is
subject to certain risks, including market risk and interest rate risk, as set
forth in detail under "INVESTMENT OBJECTIVES AND POLICIES--Risk Factors And
Investment Techniques." As with other mutual funds, there can be no assurance
that any of the Funds will achieve its investment objectives. The Funds, to the
extent set forth under "INVESTMENT OBJECTIVES AND POLICIES," may engage in the
following practices: the use of repurchase agreements and reverse repurchase
agreements, purchasing futures contracts, foreign securities and restricted
securities, entering into option transactions on securities in which the Funds
may invest directly and the purchase of securities on a when-issued or
delayed-delivery basis.

1. BISYS has agreed with the Group to waive a portion of its Rule 12b-1 Fees
   until March 1, 1997, so that such fees will not exceed during that period, on
   an annual basis, 0.01% of any Fund's average daily net assets. Absent such
   Fee Waivers, 12b-1 Fees for each of the Funds would be 0.25% and Estimated
   Total Fund Operating Expenses would be 1.00%, 1.77%, 1.50%, 1.66%, 1.22% and
   1.37% for the Money Market Fund, Diversified Equity Fund, Income Equity Fund,

  The purpose of the above table is to assist a potential purchaser of Shares of
any of the Funds in understanding the various costs and expenses that an
investor in a Fund will bear directly or indirectly. Such expenses do not
include any fees charged by the Adviser or any of its affiliates to its customer
accounts which may have invested in Shares of the Funds. See "MANAGEMENT OF THE
GROUP" and "GENERAL INFORMATION" for a more complete discussion of the
Shareholder transaction expenses and annual operating expenses of each Fund.
Except with respect to the Money Market Fund, as a result of the payment of
sales loads and Rule 12b-1 Fees, long-term Shareholders may pay more than the
maximum front-end sales charge permitted by the Rules of the National
Association of Securities Dealers, Inc. (the "NASD"). THE FOREGOING EXAMPLES
SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL
EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
   
    
                            PERFORMANCE INFORMATION
   
  From time to time performance information for the Funds showing the Funds'
average annual total return, aggregate total return, yield, tax equivalent
yield, seven-day yield and/or seven-day effective yield may be presented in
advertisements, sales literature and shareholder reports. SUCH PERFORMANCE
FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE NOT INTENDED TO INDICATE FUTURE
PERFORMANCE. Average annual total return will be calculated for the period since
commencement of operations for a Fund (or its respective predecessor collective
investment fund) and will reflect the imposition of the maximum sales charge, if
any. Average annual total return is measured by comparing the value of an
investment in such Fund at the beginning of the relevant period to the
redeemable value of the investment at the end of the period (assuming immediate
reinvestment of any dividends or capital gains distributions), which figure is
then annualized. Aggregate total return is calculated similarly to average
annual total return except that the return figure is aggregated over the
relevant period instead of annualized. Yield will be computed by dividing a
Fund's net investment income per share earned during a recent one-month period
by that Fund's per share maximum offering price (reduced by any undeclared
earned income expected to be paid shortly as a dividend) on the last day of the
period and annualizing the result. Tax equivalent yield of a Fund demonstrates
the taxable yield necessary to produce an after-tax yield equivalent to the
yield of that Fund. Each of the Funds may also present its average annual total
return, aggregate total return, yield, and tax equivalent yield, as the case may
be, excluding the effect of a sales charge, if any.
 
  Each of the Funds, other than the Money Market Fund and the Intermediate
Tax-Free Fund, will be initially funded in part by the transfer of all of the
assets of a corresponding collective investment fund managed by the Adviser and,
in the case of the Diversified Equity
    
 
                                        5
<PAGE>   6
 
   
Fund, the Sub-Advisers (the "CIFs"). Because the management of such Funds is
substantially the same as the corresponding CIF, the quoted performance of the
Funds will include the performance of the CIFs for periods prior to the
effectiveness of the Group's registration statement as it relates to those
Funds. The CIFs were not registered under the Investment Company Act of 1940, as
amended (the "1940 Act"), and therefore were not subject to certain investment
restrictions that are imposed by the 1940 Act. If the CIFs had been so
registered, their performance might have been adversely affected.
    
  The seven-day yield of the Money Market Fund refers to the income generated by
an investment therein over a seven-day period (which period will be stated in
the advertisement). This income is then "annualized." That is, the amount of
income generated by the investment during that week is assumed to be generated
each week over a 52-week period and is shown as a percentage of the investment.
The Money Market Fund may also present a 30-day yield which is calculated
similarly but instead refers to a 30-day period rather than a seven-day period.
The seven-day effective yield is calculated similarly but, when annualized, the
income earned by an investment in the Money Market Fund is assumed to be
reinvested. The seven-day effective yield is slightly higher than the seven-day
yield because of the compounding effect of this assumed reinvestment.
   
  In addition, from time to time the Funds may also present their distribution
rates in supplemental sales literature and in shareholder reports, both of which
must be accompanied or preceded by a prospectus. Distribution rates will be
computed by dividing the distribution per share made by a Fund over a
twelve-month period by the maximum offering price per share at the end of that
period. The calculation of income in the distribution rate includes both income
and capital gain dividends and does not reflect unrealized gains or losses,
although each Fund may also present a distribution rate excluding the effect of
capital gains and/or a sales charge, if any. The distribution rate differs from
the yield because it includes capital gain dividends which are often
non-recurring in nature, whereas yield does not include such items.
    
  Investors may also judge the performance of each Fund by comparing or
referencing it to the performance of other mutual funds with comparable
investment objectives and policies through various mutual fund or market indices
and to data prepared by various services, which indices or data may be published
by such services or by other services or publications. In addition to
performance information, general information about these Funds that appears in
such publications may be included in advertisements, sales literature and
reports to Shareholders.
 
  Yield and total return are generally functions of market conditions, interest
rates, types of investments held, and operating expenses. Consequently, current
yields and total return will fluctuate and are not necessarily representative of
future results. Any fees charged by FSC or by any of its affiliated or
correspondent banks, including the Adviser, to its customer accounts which may
have invested in Shares of a Fund will not be included in performance
calculations; such fees, if charged, will reduce the actual performance from
that quoted. In addition, if the Adviser or BISYS voluntarily reduces all or
part of its fees for a Fund, as discussed below, the yield and total return for
that Fund will be higher than they would otherwise be in the absence of such
voluntary fee reductions.

                       INVESTMENT OBJECTIVES AND POLICIES
 
IN GENERAL
   
  The investment objective of the Money Market Fund is current income with
liquidity and stability of principal. The investment objective for each of the
Diversified Equity Fund and the Special Equity Fund is capital appreciation. The
investment objectives of the Income Equity Fund are capital appreciation with
current income as a secondary objective. The investment objectives of the Income
Fund are current income consistent with preservation of capital. The investment
objectives of the Intermediate Tax-Free Fund are income which is exempt from
federal income tax consistent with preservation of capital.
 
  The investment objectives with respect to a Fund are non-fundamental policies
and as such may be changed by the Group's Trustees without a vote of the holders
of a majority of the outstanding Shares of that Fund (as defined below under
"GENERAL INFORMATION-- Miscellaneous"). There can be no assurance that the
investment objectives of any Fund will be achieved.
    
THE MONEY MARKET FUND
 
  Under normal market conditions, the Money Market Fund invests as fully as
possible, but in no event less than 80% of its total assets, in U.S. Treasury
bills, notes and bonds and repurchase agreements relating to such obligations.
The Money Market Fund will purchase only obligations which have, or are deemed
to have, maturities, from the date of purchase, of thirteen months or less.
Current income earned on such securities may not be as great as current income
that could be earned on lower quality securities that have less liquidity and/or
a greater risk of non-payment or securities that have a longer term.
 
  Notwithstanding any of the foregoing, the Money Market Fund, as a money market
fund subject to Rule 2a-7 of the 1940 Act, must invest exclusively in United
States dollar-denominated instruments which the Trustees of the Group and the
Adviser determine present minimal credit risks and which at the time of
acquisition are rated by one or more appropriate nationally recognized
statistical rating organizations ("NRSROs") (e.g. Standard & Poor's Corporation
and Moody's Investors Service, Inc.) in one of the two highest rating categories
for short-term debt obligations or, if unrated, are deemed to be of comparable
quality. In addition, the dollar-weighted average maturity of the obligations in
the Money Market Fund may not exceed 90 days.
 
  Subject to the foregoing limitations and in order to achieve its investment
objectives, the Money Market Fund expects to invest in the following types of
securities: direct obligations issued by the U.S. Treasury including bills,
notes and bonds which differ from each other only in interest rates, maturities
and times of issuance; U.S. Treasury securities that have been stripped of their
unmatured interest coupons (which typically provide for interest payments
semi-annually); interest coupons that have been stripped from such U.S. Treasury
securities; receipts and certificates for such stripped debt obligations and
stripped coupons (collectively, "Stripped Treasury Securities"); and in
repurchase agreements collateralized by such securities. Stripped Treasury
Securities will include (1) coupons that have been stripped from U.S. Treasury
bonds, which may be held through the Federal Reserve Bank's book-entry system
called "Separate Trading of Registered Interest and Principal of Securities"
("STRIPS") or through a program entitled "Coupon Under Book-Entry Safekeeping"
("CUBES").
   
  Treasury bills have maturities of one year or less; Treasury notes have
maturities of one to ten years; and Treasury bonds generally have maturities of
greater than ten years. Stripped Treasury Securities are sold at a deep discount
because the buyer of those securities receives
    
 
                                        7

only the right to receive a future fixed payment (representing principal or
interest) on the security and does not receive any rights to periodic interest
payments on the security. The Money Market Fund may engage in other investment
techniques described below.
 
THE DIVERSIFIED EQUITY FUND
   
  Under normal market conditions, the Diversified Equity Fund will invest
substantially all, but in no event less than 65%, of its total assets in common
stocks and securities convertible into common stocks of companies with market
capitalization of $100 million or greater--of that amount, 25% to 40% will be
committed to each of the following styles, representing the three different
styles of the Sub-Advisers: (1) investing in companies believed to have strong
value measures whose stock is traded at a price below its perceived value, (2)
investing in companies believed to have growth potential, and (3) investing in
companies believed to be in a position to take advantage of political, economic,
industrial or secular trends or developments. For purposes of the foregoing,
securities convertible into common stocks include convertible bonds, convertible
preferred stock, options and rights. To the extent the Diversified Equity Fund
invests in options or rights, such investments may contribute to its primary
investment objective of capital appreciation but will not contribute to its
secondary objective of current income.
    
  Miller Anderson & Sherrerd LLP, one of the Sub-Advisers ("Miller Anderson"),
will manage its portion of the Diversified Equity Fund's portfolio with an
emphasis on equity securities of companies it believes have traditional value
characteristics, i.e., high yield, low price to earnings ratios and low price to
book value ratios, which Miller Anderson believes have unrecognized potential
for earnings improvement.
 
  Loomis, Sayles & Company, L.P., another of the Sub-Advisers ("Loomis"), will
manage its portion of the Diversified Equity Fund's portfolio with an emphasis
on equity securities of companies Loomis believes are entering into a phase of
accelerating earnings growth. The criteria used by Loomis to select such
securities are historic and current relative price to earnings ratios, and the
extent to which Loomis believes that the market has recognized the accelerating
growth of such company.
 
  Columbus Circle Investors, the third Sub-Adviser ("Columbus"), will manage its
portion of the Diversified Equity Fund's portfolio based upon Columbus's
identification of companies where political or economic developments, secular
trends, industry or group dynamics and company-specific events present greater
that market expected growth.
   
  Under normal market conditions, the Diversified Equity Fund may also invest up
to 35% of its total assets in sponsored and unsponsored American Depositary
Receipts ("ADRs"), as described more fully below, securities of other investment
companies, units of real estate investment trusts ("REITs"), warrants, cash and
short-term obligations (with maturities of 12 months or less) (collectively,
"Short-Term Obligations") such as commercial paper, bankers' acceptances,
certificates of deposit, obligations of the U.S. Government or its agencies or
instrumentalities, demand and time deposits of domestic banks and savings and
loan associations and repurchase agreements secured by such Short-Term
Obligations. Commercial paper which is included within "Short-Term Obligations"
is that which is rated at the time of purchase within the two highest rating
groups assigned by one or more appropriate NRSROs, or, if unrated, which the
Adviser or the Sub-Adviser deems to be of comparable quality. For a description
of the rating symbols of the NRSROs, see the Appendix to the Statement of
Additional Information. The Diversified Equity Fund may also engage in other
investment techniques described below.

THE INCOME EQUITY FUND
 
  Under normal market conditions, the Income Equity Fund will invest
substantially all, but in no event less than 65%, of its total assets in common
stocks and securities convertible into common stocks of companies with market
capitalization of at least $100 million which the Adviser believes pay above
average dividends or interest. For purposes of the foregoing, securities
convertible into common stocks include convertible bonds, convertible preferred
stock, options and rights. The securities purchased by the Income Equity Fund
are those considered by the Adviser to be generally undervalued by the market.
 
  Under normal market conditions, the Income Equity Fund may also invest up to
35% of its total assets in warrants, ADRs, securities of other investment
companies and REITs, cash and Short-Term Obligations and may engage in other
investment techniques described below.
 
THE SPECIAL EQUITY FUND
   
  Under normal market conditions, the Special Equity Fund will invest
substantially all, but in no event less than 65%, of its total assets in common
stocks and securities convertible into common stocks (i.e., convertible bonds,
convertible preferred stock, options and rights), traded in U.S. markets, and
issued by companies believed by the Adviser to exhibit an attractive outlook for
growth in sales and earnings and with market capitalizations of between $50
million and $1.5 billion. Such companies may include "unseasoned" companies,
i.e., companies that, together with any predecessor, have less than three years
of continuous operation. The Special Equity Fund will not invest more than 25%
of its total assets in the securities of unseasoned companies.
    
  The Special Equity Fund may also invest up to 35% of its total assets in
warrants, ADRs, securities of other investment companies and REITs, cash and
Short-Term Obligations and may engage in other investment techniques described
below.
 
THE INCOME FUND
 
  Under normal market conditions, the Income Fund will invest substantially all,
but in no event less than 65%, of its total assets in debt securities of all
types, including variable and floating rate securities (as described more fully
below under "The Intermediate Tax-Free Fund"), although up to 35% of its total
assets may be invested in securities of other investment companies and in
preferred stock and dividend paying common stocks. Debt securities include
bonds, debentures, notes, mortgage-related securities, state, municipal or
industrial revenue bonds, obligations issued or guaranteed as to principal and
interest by the U.S. Government or its agencies or instrumentalities
("Government Obligations") and fixed-income securities convertible into, or
exchangeable for, common stocks. In addition, a portion of the Income Fund may
from time to time be invested in participation certificates in pools of
mortgages issued or guaranteed by the U.S. Government or its agencies or
instrumentalities.
 
  Under normal market conditions, the Income Fund expects to invest primarily in
Government Obligations and in debt obligations of United States corporations.
The Income Fund also intends that, under normal market conditions, its portfolio
will maintain a dollar-weighted average maturity of no more than 18 years.
 
  The Income Fund expects to invest in a variety of U.S. Treasury obligations,
differing in their interest rates, maturities, and times of issuance, and other
Government Obligations. Obligations of certain agencies and instrumentalities of
the U.S. Government, such as the Government National Mortgage Association and
the Export-Import Bank of the United States, are supported by the full faith and
credit of the U.S. Treasury; others, such as
 
                                        9
<PAGE>   10
 
those of the Federal National Mortgage Association, are supported by the right
of the issuer to borrow from the Treasury; others, such as those of the Student
Loan Marketing 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 Federal Farm Credit Banks or the Federal Home Loan Mortgage
Corporation, 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 agencies or instrumentalities if it is not
obligated to do so by law. The Income Fund will invest in the obligations of
such agencies or instrumentalities only when the Adviser believes that the
credit risk with respect thereto is minimal.
 
  The Income Fund also expects to invest in bonds, notes and debentures of a
wide range of U.S. corporate issuers. Such obligations, in the case of
debentures, will represent unsecured promises to pay, in the case of notes and
bonds, may be secured by mortgages on real property or security interests in
personal property and will in most cases differ in their interest rates,
maturities and times of issuance.
   
  The Income Fund will invest only in corporate debt securities which are rated
at the time of purchase within the three highest rating groups assigned by one
or more appropriate NRSROs or, if unrated, which the Adviser deems to be of
comparable quality. In the event that a security's rating falls below "A" by an
appropriate NRSRO, the Adviser will reevaluate the security in order to
determine whether to sell. In no event, however, will the Income Fund be
required to liquidate such security if it would suffer a loss on the sale of
such security or so long as one appropriate NRSRO has rated such security within
its three highest rating groups. For a description of the rating symbols of the
NRSROs, see the Appendix to the Statement of Additional Information.
    
  The Income Fund may hold some Short-Term Obligations and securities of other
investment companies for cash management purposes.
 
  The Income Fund may also invest in U.S. dollar denominated international bonds
for which the primary trading market is in the United States ("Yankee Bonds"),
or for which the primary trading market is abroad ("Eurodollar Bonds"), and in
Canadian Bonds and bonds issued by institutions organized for a specific
purpose, such as the World Bank and the European Economic Community, by two or
more sovereign governments ("Supranational Agency Bonds").
   
  The Income Fund may invest up to 25% of its total assets in mortgage-related
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities or by nongovernmental entities which are rated, at the time of
purchase, within the three highest bond rating categories assigned by one or
more appropriate NRSROs, or, if unrated, which the Adviser deems present
attractive opportunities and are of comparable quality. Such mortgage-related
securities have mortgage obligations backing such securities, including among
others, conventional thirty year fixed rate mortgage obligations, graduated
payment mortgage obligations, fifteen year mortgage obligations and adjustable
rate mortgage obligations. All of these mortgage obligations can be used to
create pass-through securities. A pass-through security is created when mortgage
obligations are pooled together and undivided interests in the pool or pools are
sold. The cash flow from the mortgage obligations is passed through to the
holders of the securities in the form of periodic payments of interest,
principal and prepayments (net of a service fee). Prepayments occur when the
holder of an individual mortgage obligation prepays the remaining principal
before the mortgage obligation's scheduled maturity date. As a result of the
pass-through of prepayments of principal on the underlying securities,
mortgage-backed securi-
    
 
                                       10
<PAGE>   11
 
ties are often subject to more rapid prepayment of principal than their stated
maturity would indicate. Because the prepayment characteristics of the
underlying mortgage obligations vary, it is not possible to predict accurately
the realized yield or average life of a particular issue of pass-through
certificates. Prepayment rates are important because of their effect on the
yield and price of the securities. In addition, prepayment rates will be used to
determine a security's estimated average life and the Income Fund's average
portfolio duration and its dollar-weighted average portfolio maturity.
Accelerated prepayments have an adverse impact on yields for pass-through
securities purchased at a premium (i.e., a price in excess of principal amount)
and may involve additional risk of loss of principal because the premium may not
have been fully amortized at the time the obligations are repaid. The opposite
is true for pass-through securities purchased at a discount. The Income Fund may
purchase mortgage-related securities at a premium or a discount. Reinvestment of
principal payments may occur at higher or lower rates than the original yield on
such securities. Due to the prepayment feature and the need to reinvest payments
and prepayments of principal at current rates, mortgage-related securities can
be less effective than typical bonds of similar maturities at maintaining yields
during periods of declining interest rates.
 
  Certain debt securities such as, but not limited to, mortgage-backed
securities, collateralized mortgage obligations (CMOs), asset backed securities
and securitized loan receivables, as well as securities subject to prepayment of
principal prior to the stated maturity date, are expected to be repaid prior to
their stated maturity dates. As a result, the effective maturity of these
securities is expected to be shorter than the stated maturity. For purposes of
compliance with stated maturity policies and calculation of the Income Fund's
dollar-weighted average maturity, the effective maturity of such securities will
be used.
 
  An increase in interest rates will generally reduce the value of the
investments in the Income Fund, and a decline in interest rates will generally
increase the value of those investments. Depending upon the prevailing market
conditions, the Adviser may purchase debt securities at a discount from face
value, which produces a yield greater than the coupon rate. Conversely, if debt
securities are purchased at a premium over face value, the yield will be lower
than the coupon rate. In making investment decisions, the Adviser will consider
many factors other than current yield, including the preservation of capital,
maturity, and yield to maturity.
 
THE INTERMEDIATE TAX-FREE FUND
   
  Under normal market conditions, at least 80% of the net assets of the
Intermediate Tax-Free Fund will be invested in a portfolio of obligations
consisting of bonds, notes, commercial paper, certificates of indebtedness and
other debt instruments, issued by or on behalf of the various States of the
United States, or any county, political subdivision or municipality thereof
(including any agency, board, authority or commission of any of the foregoing),
the interest on which, in the opinion of bond counsel to the issuer, is exempt
from federal income tax and is not treated as a preference item for individuals
for purposes of the federal alternative minimum tax. The Intermediate Tax-Free
Fund may also invest in debt obligations issued by the Government of Puerto Rico
and such other governmental entities whose debt obligations, either by law or
treaty, generate interest income which is exempt from federal income taxes and
is not treated as a preference item for individuals for purposes of the federal
alternative minimum tax (collectively, "Exempt Securities"). The Intermediate
Tax-Free Fund, under normal market conditions, expects to maintain an average
weighted portfolio maturity of four to eight years.
    
  The two principal classifications of Exempt Securities which may be held by
the Intermedi-
 
                                       11
<PAGE>   12
 
ate Tax-Free Fund are "general obligation" securities and "revenue" securities.
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 proceeds of a special
excise tax or other specific revenue source such as the user of the facility
being financed. Private activity bonds held by the Intermediate Tax-Free Fund
are in most cases revenue securities and are not payable from the unrestricted
revenues of the issuer. Consequently, the credit quality of private activity
bonds is usually directly related to the credit standing of the corporate user
of the facility involved.
 
  The Intermediate Tax-Free Fund may also invest in "moral obligation"
securities, which are normally issued by special purpose public authorities. 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.
 
  The Intermediate Tax-Free Fund invests in Exempt Securities which are rated at
the time of purchase within the three highest rating groups assigned by one or
more appropriate NRSROs for bonds, notes, tax-exempt commercial paper, or
variable rate demand obligations, as the case may be. The Intermediate Tax-Free
Fund may also purchase Exempt Securities which are unrated at the time of
purchase but are determined to be of comparable quality by the Adviser. In the
event that a security's rating falls below "A" by an appropriate NRSRO, the
Adviser will reevaluate the security in order to determine whether to sell. In
no event, however, will the Intermediate Tax-Free Fund be required to liquidate
such security if it would suffer a loss on the sale of such security or so long
as one appropriate NRSRO has rated such security within its three highest rating
groups. The applicable Exempt Securities ratings are described in the Appendix
to the Statement of Additional Information.
 
  The Intermediate Tax-Free Fund may hold uninvested cash reserves pending
investment during temporary defensive periods or if, in the opinion of the
Adviser, suitable Exempt Securities are unavailable. There is no percentage
limitation on the amount of assets which may be held uninvested. Uninvested cash
reserves will not earn income. In addition, investments of the Intermediate
Tax-Free Fund may be made in taxable Short-Term Obligations if, for example,
suitable tax-exempt obligations are unavailable. Under such circumstances and
during the period of such investment, the Intermediate Tax-Free Fund may not
achieve its stated investment objectives.
 
  The Intermediate Tax-Free Fund may also invest up to 20% of its net assets in
municipal securities, the interest income on which is exempt from federal income
tax but may be treated as a preference item for individuals for purposes of the
federal alternative minimum tax. The Intermediate Tax-Free Fund will not include
such municipal securities in the calculation of compliance with the 80% test
described above as a fundamental policy of the Intermediate Tax-Free Fund. For
further information relating to the types of municipal securities which will be
included in income subject to alternative minimum tax, see "ADDITIONAL
INFORMATION--Additional Tax Information" in the Statement of Additional
Information.
 
  Opinions relating to the validity of Exempt Securities and to the exemption of
interest thereon from federal income taxes are normally rendered by bond counsel
to the respective issuers at the time of issuance. Neither the Intermediate
Tax-Free Fund nor the Adviser will review the proceedings relating to the issu-
 
                                       12
<PAGE>   13
 
ance of Exempt Securities or the basis for such opinions.
   
  Exempt Securities purchased by the Intermediate Tax-Free Fund may include
rated and unrated variable and floating rate obligations the interest on which
is tax-exempt. A variable rate obligation is one whose terms provide for the
adjustment of its interest rate on set dates and which, upon such adjustment,
can reasonably be expected to have a market value that approximates its par
value.
 
  A floating rate obligation is one whose terms provide for the adjustment of
its interest rate whenever a specified interest rate changes and which, at any
time, can reasonably be expected to have a market value that approximates its
par value. Such obligations are frequently not rated by credit rating agencies;
however, unrated variable and floating rate obligations purchased by the
Intermediate Tax-Free Fund will be determined by the Adviser to be of comparable
quality at the time of purchase to rated instruments eligible for purchase under
the Intermediate Tax-Free Fund's investment policies. In making such
determinations, the Adviser will consider the earning power, cash flow and other
liquidity ratios of the issuers of such obligations (such issuers include
financial, merchandising, bank holding and other companies) and will
continuously monitor their financial condition. Although there may be no active
secondary market with respect to a particular variable or floating rate
obligation purchased by the Intermediate Tax-Free Fund, the Intermediate
Tax-Free Fund may attempt to resell the obligation at any time to a third party.
The absence of an active secondary market, however, could make it difficult for
the Intermediate Tax-Free Fund to dispose of a variable or floating rate
obligation in the event the issuer of the obligation defaulted on its payment
obligations and the Intermediate Tax-Free Fund could, as a result or for other
reasons, suffer a loss to the extent of the default. Variable or floating rate
obligations may be secured by bank letters of credit.
 
  In the event the interest rate of a variable or floating rate obligation is
established by reference to an index or an interest rate that may from time to
time lag behind other market interest rates, there is the risk that the market
value of such obligation, on readjustment of its interest rate, will not
approximate its par value.
 
  Variable and floating rate obligations for which no readily available market
exists will be purchased in an amount which, together with other illiquid
securities, exceeds 15% of the Intermediate Tax-Free Fund's net assets only if
such obligations are subject to a demand feature that will permit the
Intermediate Tax-Free Fund to receive payment of the principal within seven days
after demand by the Intermediate Tax-Free Fund.
    
  An increase in interest rates will generally reduce the value of the
investments in the Intermediate Tax-Free Fund, and a decline in interest rates
will generally increase the value of those investments. Depending upon the
prevailing market conditions, the Adviser may purchase debt securities at a
discount from face value, which produces a yield greater than the coupon rate.
Conversely, if debt securities are purchased at a premium over face value, the
yield will be lower than the coupon rate. In making investment decisions, the
Adviser will consider many factors other than current yield, including the
preservation of capital, maturity, and yield to maturity.
 
IN GENERAL
   
  Each of the Funds, other than the Money Market Fund, may purchase securities
of other investment companies which in the opinion of the Adviser or
Sub-Adviser, as the case may be, will assist such Fund in achieving its
investment objective and/or for cash management purposes, and each of the Funds
may enter into repurchase and reverse repurchase agreements, and except for the
Money Market Fund, the Intermediate Tax-Free Fund and the Income Fund, enter
into options and futures
    
 
                                       13
<PAGE>   14
 
transactions and write covered-call options on securities that such Fund could
otherwise purchase directly. In addition, the Income Fund and the Intermediate
Tax-Free Fund may purchase securities on a when-issued basis. Use by the
Intermediate Tax-Free Fund of one or more of these investment techniques may
cause such Fund to earn income which would be taxable to its Shareholders.
   
  The securities purchased by the Funds are traded on U.S. markets, including
the New York Stock Exchange, the American Stock Exchange and NASDAQ, although
each of the Diversified Equity Fund, Income Equity Fund, Special Equity Fund and
Income Fund may purchase securities which are restricted as to their
disposition, including those eligible for resale under Rule 144A under the
Securities Act of 1933 ("Rule 144A Securities").
    
  During temporary defensive periods as determined by the Adviser or the
appropriate Sub-Adviser, as the case may be, based upon current or anticipated
market conditions, each Fund may hold up to 100% of its total assets in
Short-Term Obligations as described above or in cash. However, to the extent
that a Fund is so invested, it may not achieve its investment objective or
objectives.
   
  Each of the Funds, other than the Money Market Fund, may invest in certain
types of securities which are considered to be "derivative" securities, such as
certain variable or floating rate securities, options and futures. A derivative
is generally defined as an instrument whose value is based upon, or derived
from, some underlying index, reference rate (e.g., interest rates), security,
commodity or other asset. The Diversified Equity Fund, the Income Equity Fund,
the Special Equity Fund and the Intermediate Tax-Free Fund each will not invest
more than 25% of its total assets in such derivatives. With respect to the
Income Fund, such Fund may invest up to 25% of its total assets in CMOs and up
to 25% of its total assets in any other derivatives. Notwithstanding the
foregoing, with respect to the Income and Intermediate Tax-Free Funds, there is
no limitation on the amount of their total assets which may be invested in
variable or floating rate obligations regardless of whether or not such
obligations are deemed to be "derivatives."
    
RISK FACTORS AND INVESTMENT TECHNIQUES
 
  Like any investment program, an investment in any of the Funds entails certain
risks. Equity securities such as those in which the Diversified Equity, Income
Equity and Special Equity Funds may invest are more volatile and carry more risk
than some other forms of investment, including investments in high grade fixed
income securities. Therefore, such Funds are subject to stock market risk, i.e.,
the possibility that stock prices in general will decline over short or even
extended periods of time.
   
  Since the Income and Intermediate Tax-Free Funds invest in bonds, investors in
such a Fund, to the extent so invested, are exposed to bond market risk, i.e.,
fluctuations in the market value of bonds. Bond prices are influenced primarily
by changes in the level of interest rates. When interest rates rise, the prices
of bonds generally fall; conversely, when interest rates fall, bond prices
generally rise. While bonds normally fluctuate less in price than stocks, there
have been in the recent past extended periods of cyclical increases in interest
rates that have caused significant declines in bond prices and have caused the
effective maturity of securities with pre-payment features to be extended, thus
effectively converting short or intermediate term securities into longer term
securities.
    
  The Special Equity Fund is intended for investors who can accept the higher
risks involved in seeking potentially higher capital appreciation through
investments in growth oriented companies. A growth oriented company typically
invests most of its net income in its enterprise and does not pay out much, if
any, in dividends. Accordingly, the Special Equity Fund does not anticipate any
significant distributions to shareholders from net invest-
 
                                       14
<PAGE>   15
 
ment income, and potential investors should be in a financial position to forego
current income from their investment in the Special Equity Fund. The securities
of less seasoned companies may have limited marketability and may be subject to
more abrupt or erratic market movements over time than securities of more
seasoned companies or the market as a whole.
 
  Depending upon the performance of each Funds' investments, the net asset value
per share of a Fund may decrease instead of increase, except with respect to the
Money Market Fund, the net asset value of which the Adviser will attempt to
maintain at $1.00.
   
  Repurchase Agreements. Securities held by each Fund may be subject to
repurchase agreements. Under the terms of a repurchase agreement, a Fund would
acquire securities, in exchange for cash from banks and/or registered
broker-dealers which the Adviser or Sub-Adviser, as the case may be, deems
creditworthy under guidelines approved by the Group's Board of Trustees. The
seller agrees to repurchase such securities at a mutually agreed date and price.
The repurchase price 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 underlying portfolio securities. Securities subject to
repurchase agreements must be of the same type and quality as those in which
such Fund may invest directly. For further information about repurchase
agreements and the related risks, see "INVESTMENT OBJECTIVES AND
POLICIES--Additional Information on Portfolio Instruments--Repurchase
Agreements" in the Statement of Additional Information.
 
  Reverse Repurchase Agreements. Each Fund may borrow funds by entering into
reverse repurchase agreements in accordance with the investment restrictions
described below. Pursuant to such agreements, a Fund would sell portfolio
securities to financial institutions such as banks and broker-dealers, and agree
to repurchase them at a mutually agreed-upon date and price. At the time a Fund
enters into a reverse repurchase agreement, it will place in a segregated
custodial account assets such as U.S. Government securities or other liquid
high-grade debt securities consistent with such Fund's investment restrictions
having a value equal to the repurchase price (including accrued interest), and
will continually monitor the account to ensure that such equivalent value is
maintained at all times. Reverse repurchase agreements involve the risk that the
market value of the securities sold by a Fund may decline below the price at
which the Fund is obligated to repurchase the securities. Reverse repurchase
agreements are considered to be borrowings by a Fund under the 1940 Act and
therefore a form of leverage. A Fund may experience a negative impact on its net
asset value if interest rates rise during the term of a reverse repurchase
agreement. A Fund generally will invest the proceeds of such borrowings only
when such borrowings will enhance the Fund's liquidity or when the Fund
reasonably expects that the interest income to be earned from the investment of
the proceeds is greater than the interest expense of the transaction. For
further information about, and limitations on the use of, reverse repurchase
agreements, see investment restriction no. 3 under "INVESTMENT RESTRICTIONS"
below and "INVESTMENT OBJECTIVES AND POLICIES--Additional Information on
Portfolio Instruments--Reverse Repurchase Agreements" in the Statement of
Additional Information.
    
  Except as otherwise disclosed to the Shareholders of the Funds, the Group will
not execute portfolio transactions through, acquire portfolio securities issued
by, make savings deposits in, or enter into repurchase or reverse repurchase
agreements with the Adviser, any Sub-Adviser, BISYS, or their affiliates, and
will not give preference to the Adviser's correspondents with respect to such
transactions, securities, savings deposits, repurchase agreements, and reverse
repurchase agreements.
 
                                       15
<PAGE>   16
 
  Options. The Diversified Equity Fund, the Income Equity Fund, the Special
Equity Fund and the Income Fund may also each purchase put and call options for
hedging purposes. Such Funds anticipate that options will be exchange traded
options, meaning that such options are generally standardized and are guaranteed
by a clearing agency, which is in contrast to over-the-counter or OTC traded
options. A put option gives the purchaser of the option the right to sell, and
obligates the writer (seller) of the option to buy, 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. A call option gives the
purchaser of the option the right to buy, and obligates the seller of the option
to sell, 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. Purchasing options is a specialized investment technique that entails
a substantial risk of a complete loss of the amounts paid as premiums to writers
of options.
 
  For hedging purposes, each of such Funds may also engage in writing call
options from time to time as the Adviser or the Sub-Adviser, as the case may be,
deems appropriate. A Fund will write only covered call options (options on
securities owned by that Fund). When a Fund writes a covered call option and
such option is exercised, that Fund will forego the appreciation, if any, on the
underlying security in excess of the exercise price. In order to close out a
call option it has written, a Fund will enter into a "closing purchase
transaction"--the purchase of a call option on the same security with the same
exercise price and expiration date as the call option which that Fund previously
wrote on any particular securities. When a portfolio security subject to a call
option is sold, the Fund which wrote the call will effect a closing purchase
transaction to close out any existing call option on that security. There is no
assurance of liquidity in the secondary market for purposes of closing out
options positions. If that Fund is unable to effect a closing purchase
transaction, it will not be able to sell the underlying security until the
option expires or such Fund delivers the underlying security upon exercise.
   
  Each of those Funds, as part of its options transactions, also may purchase
index put and call options and write index options. As with options on
individual securities, a Fund will write only covered index call options.
Through the writing or purchase of index options a Fund can achieve many of the
same objectives as through the use of options on individual securities. Options
on securities indices are similar to options on a security except that, rather
than the right to take or make delivery of a security at a specified price, an
option on a securities index gives the holder the right to receive, upon
exercise of the option, an amount of cash if the closing level of the securities
index upon which the option is based is greater than, in the case of a call, or
less than, in the case of a put, the exercise price of the option.
    
  A Fund may lose the expected benefit of options transactions if interest rates
or securities prices move in an unanticipated manner. In addition, the value of
a Fund's options positions may not prove to be perfectly or even highly
correlated with the value of its portfolio securities, limiting such Fund's
ability to hedge effectively against market or interest rate risk. Because index
options are settled in cash, a call writer cannot determine the amount of its
settlement obligations in advance and, unlike call writing on specific
securities, cannot provide in advance for, or cover, its potential settlement
obligations by acquiring and holding the underlying securities. A Fund may be
required to segregate assets or provide an initial margin to cover index options
that would require it to pay cash upon exercise. Under normal conditions, it is
not expected that any such Fund would permit the underlying value of its
portfolio securities subject to such options to exceed 25% of its net assets.
 
                                       16

  In addition, the Intermediate Tax-Free Fund may acquire "puts" with respect to
Exempt Securities held in its portfolio. Under a put, the Intermediate Tax-Free
Fund would have the right to sell a specified Exempt Security within a specified
period of time at a specified price. A put would be sold, transferred, or
assigned only with the underlying security. The Intermediate Tax-Free Fund will
acquire puts solely to either facilitate portfolio liquidity, shorten the
maturity of the underlying securities, or permit the investment of its funds at
a more favorable rate of return. The Intermediate Tax-Free Fund expects that it
will generally acquire puts only where the puts are available without the
payment of any direct or indirect consideration. However, if necessary or
advisable, the Intermediate Tax-Free Fund may pay for a put either separately in
cash or by paying a higher price for portfolio securities which are acquired
subject to the puts (thus reducing the yield to maturity otherwise available for
the same securities).
 
  Futures Contracts. Each Fund, other than the Money Market Fund, may also enter
into contracts for the future delivery of securities and futures contracts based
on a specific security, class of securities, interest rate or an index, purchase
or sell options on any such futures contracts and engage in related closing
transactions. A futures contract on a securities index or based on an interest
rate is an agreement obligating either party to pay, and entitling the other
party to receive, while the contract is outstanding, cash payments based on the
level of a specified securities index or interest rate, as the case may be. A
Fund may use this investment technique as a substitute for a comparable market
position in the underlying securities or to hedge against anticipated future
changes in market prices or interest rates, which otherwise might adversely
affect either the value of such Fund's securities or the prices of securities
which the Fund intends to purchase at a later date. Alternatively, a Fund may
purchase or sell futures contracts to hedge against changes in market interest
rates which may result in the premature call at par value of certain securities
which the Fund has purchased at a premium.
   
  Each such Fund may engage in such futures contracts in an effort to hedge
against market risks. For example, when interest rates are expected to rise or
market values of portfolio securities are expected to fall, a Fund can seek
through the sale of futures contracts to offset a decline in the value of its
portfolio securities. When interest rates are expected to fall or market values
are expected to rise, a Fund, through the purchase of such contracts, can
attempt to secure better rates or prices for such Fund than might later be
available in the market when it effects anticipated purchases.

  The acquisition of put and call options on futures contracts will,
respectively, give a Fund the right (but not the obligation), for a specified
price, to sell or to purchase the underlying futures contract, upon exercise of
the option, at any time during the option period. A Fund may also sell options
on futures contracts as part of closing purchase transactions to terminate its
options positions. No assurance can be given that such closing transactions can
be effected, that there will be a correlation between price movements in the
Fund's portfolio securities which are the subject of the hedge or of liquidity
in the secondary market for purposes of closing out future positions. In
addition, a Fund's purchase of such options will be based upon predictions as to
anticipated interest rate or other market trends, which could prove to be
inaccurate.
    
  In general, the value of futures contracts sold by a Fund to offset declines
in its portfolio securities will not exceed the total market value of the
portfolio securities to be hedged, and futures contracts purchased by a Fund
will be covered by a segregated account consisting of cash or liquid securities
in an amount equal to the total market value of such futures contracts, less the
initial margin deposited therefor.
 
                                       17
<PAGE>   18
 
  When buying futures contracts and when writing put options, a Fund will be
required to segregate in a separate account cash and/or U.S. Government
securities in an amount sufficient to meet its obligations. When writing call
options, a Fund will be required to own the financial instrument or futures
contract underlying the option or segregate cash and/or U.S. Government
securities in an amount sufficient to meet its obligations under written calls.
 
  Aggregate initial margin deposits for futures contracts, and premiums paid for
related options, may not exceed five percent of a Fund's total assets, and the
value of securities that are the subject of such futures and options (both for
receipt and delivery) may not exceed one-third of the market value of a Fund's
total assets. Futures transactions will be limited to the extent necessary to
maintain each Fund's qualifications as a regulated investment company.
 
  A Fund may lose the expected benefit of futures transactions if interest rates
or securities prices move in an unanticipated manner. Such unanticipated changes
may also result in poorer overall performance than if the Fund had not entered
into any futures transactions. In addition, the value of a Fund's futures
positions may not prove to be perfectly or even highly correlated with the value
of its portfolio securities, limiting such Fund's ability to hedge effectively
against interest rate and/or market risk and giving rise to additional risks.
For futures contracts based on indices, the risk of imperfect correlation
increases as the composition of the Fund's portfolio varies from the composition
of the index. In an effort to compensate for the imperfect correlation of
movements in the price of the securities being hedged and movements in the price
of futures contracts, a Fund may buy or sell futures contracts in a greater or
lesser dollar amount than the dollar amount of the securities being hedged if
the historical volatility of the futures contract has been less or greater than
that of the securities. Such "over hedging" or "under hedging" may adversely
affect the Fund's net investment results if the market does not move as
anticipated when the hedge is established.
 
  Foreign Investments. As described above, each of the Diversified Equity,
Income Equity and Special Equity Funds may invest in sponsored and unsponsored
ADRs. Unsponsored ADRs may be less liquid than sponsored ADRs, and there may be
less information available regarding the underlying foreign issuer for
unsponsored ADRs. Investments in foreign securities, including ADRs, may subject
a Fund to investment risks that differ in some respects from those related to
investments in securities of U.S. domestic issuers. Such risks include future
adverse political and economic developments, the possible imposition of
withholding taxes on interest or other investment income, possible seizure,
nationalization, or expropriation of foreign deposits or investments, the
possible establishment of exchange controls or taxation at the source, less
stringent disclosure requirements, less liquid or developed securities markets
or the adoption of other foreign governmental restrictions which might adversely
affect the payment of principal, interest or dividends on such securities or the
purchase or sale thereof. In addition, foreign branches of U.S. banks and
foreign banks may be subject to less stringent reserve requirements and to
different accounting, auditing, reporting, and recordkeeping standards than
those applicable to domestic branches of U.S. banks. A Fund will acquire
securities issued by foreign branches of U.S. banks, foreign banks, or other
foreign issuers only when the Adviser believes that the risks associated with
such instruments are minimal.
 
  Securities Lending. In order to generate additional income, each Fund may,
from time to time, lend its portfolio securities to broker-dealers, banks, or
institutional borrowers of securities. A Fund must receive 100% collateral in
the form of cash or U.S. Government securities. This collateral will be valued
daily by the Adviser or the Sub-Adviser, as the case may be. Should the market
value of the loaned securities increase, the borrower must furnish additional
collateral to that Fund. During the time
 
                                       18
<PAGE>   19
   
portfolio securities are on loan, the borrower pays that Fund any dividends or
interest received on such securities. Loans are subject to termination by such
Fund or the borrower at any time. While a Fund does not have the right to vote
securities on loan, each Fund intends to terminate the loan and regain the right
to vote if that is considered important with respect to the investment. In the
event the borrower would default on its obligations, the Fund bears the risk of
delay in recovery of the portfolio securities and the loss of rights in the
collateral. A Fund will enter into loan agreements only with broker-dealers,
banks, or other institutions that the Adviser or the Sub-Adviser, as the case
may be, has determined are creditworthy under guidelines established by the
Group's Board of Trustees.
    
  When-Issued and Delayed Delivery Transactions. The Income Fund and the
Intermediate Tax-Free Fund may purchase securities on a when-issued or
delayed-delivery basis. These transactions are arrangements in which a Fund
purchases securities with payment and delivery scheduled for a future time. The
Income Fund and the Intermediate Tax-Free Fund will engage in when-issued and
delayed-delivery transactions only for the purpose of acquiring portfolio
securities consistent with and in furtherance of its investment objective and
policies, not for investment leverage, although such transactions represent a
form of leveraging. When-issued securities are securities purchased for delivery
beyond the normal settlement date at a stated price and yield and thereby
involve a risk that the yield obtained in the transaction will be less than
those available in the market when delivery takes place. A Fund will generally
not pay for such securities or start earning interest on them until they are
received on the settlement date. When a Fund agrees to purchase such securities,
however, its custodian will set aside cash or liquid securities equal to the
amount of the commitment in a separate account. Securities purchased on a
when-issued basis are recorded as an asset and are subject to changes in the
value based upon changes in the general level of interest rates. In when-issued
and delayed-delivery transactions, the Fund relies on the seller to complete the
transaction; the seller's failure to do so may cause such Fund to miss a price
or yield considered to be advantageous.
   
  Restricted Securities. Securities in which the Diversified Equity Fund, the
Income Equity Fund, the Special Equity Fund and the Income Fund may invest
include securities issued by corporations without registration under the
Securities Act of 1933, as amended (the "1933 Act"), such as securities issued
in reliance on the so-called "private placement" exemption from registration
which is afforded by Section 4(2) of the 1933 Act ("Section 4(2) securities").
Section 4(2) securities are restricted as to disposition under the Federal
securities laws, and generally are sold to institutional investors such as the
Funds who agree that they are purchasing the securities for investment and not
with a view to public distribution. Any resale must also generally be made in an
exempt transaction. Section 4(2) securities are normally resold, if at all, to
other institutional investors through or with the assistance of the issuer or
investment dealers who facillitate the resale of such Section 4(2) securities,
thus providing some liquidity.
 
  Pursuant to procedures adopted by the Board of Trustees of the Group, the
Adviser, or the Sub-Adviser, as the case may be, may determine Section 4(2)
securities to be liquid if such securities are eligible for resale under Rule
144A under the 1933 Act and are readily saleable. Rule 144A permits a Fund to
purchase securities which have been privately placed and resell such securities
to certain qualified institutional buyers without restriction. For purposes of
determining whether a Rule 144A security is readily saleable, and therefore
liquid, the Adviser or the Sub-Adviser, as the case may be, must consider, among
other things, the frequency of trades and quotes for the security, the number of
dealers willing to purchase or sell the security and the number of potential
purchasers, dealer undertakings to make a mar-
    
 
                                       19
<PAGE>   20
 
ket in the security, and the nature of the security and marketplace trades of
such security. However, investing in Rule 144A securities, even if such
securities are initially determined to be liquid, could have the effect of
increasing the level of the Fund's illiquidity to the extent that qualified
institutional buyers become, for a time, uninterested in purchasing these
securities.
   
  Investment Company Securities. Each Fund, other than the Money Market Fund,
may also invest in the securities of other investment companies in accordance
with the limitations of the 1940 Act and any exemptions therefrom. Each Fund
intends to invest in the securities of other investment companies which, in the
opinion of the Adviser or the Sub-Adviser, as the case may be, will assist such
Fund in achieving its investment objectives and in money market mutual funds for
purposes of short-term cash management. A Fund will incur additional expenses
due to the duplication of fees and expenses as a result of investing in mutual
funds. Additional restrictions on the Funds' investments in the securities of
other mutual funds are described in the Statement of Additional Information.
    
PORTFOLIO TURNOVER
 
  The portfolio turnover rate for each Fund is calculated by dividing the lesser
of a Fund's purchases or sales of portfolio securities for the year by the
monthly average value of the portfolio securities. The Commission requires that
the calculation exclude all securities whose remaining maturities at the time of
acquisition are one year or less. For the Money Market Fund, portfolio turnover
rate is expected to be zero percent for regulatory purposes. The portfolio
turnover rate for each of the other Funds may vary greatly from year to year, as
well as within a particular year, and may also be affected by cash requirements
for redemptions of Shares. High portfolio turnover rates will generally result
in higher transaction costs, including brokerage commissions, to a Fund and may
result in additional tax consequences to a Fund's shareholders. Portfolio
turnover will not be a limiting factor in making investment decisions.
 
                            INVESTMENT RESTRICTIONS
 
  Each Fund is subject to a number of investment restrictions that may be
changed only by a vote of a majority of the outstanding Shares of that Fund (as
defined under "GENERAL INFORMATION--Miscellaneous" herein).
 
  Each of the Funds will not:
 
    1. Purchase securities of any one issuer, other than obligations issued or
  guaranteed by the U.S. Government, its agencies or instrumentalities and
  repurchase agreements secured by such obligations, if, immediately after such
  purchase, more than 5% of such Fund's total assets would be invested in such
  issuer, or such Fund would hold more than 10% of outstanding voting securities
  of such issuer, except that up to 25% of a Fund's total assets may be invested
  without regard to such limitations. There is no limit to the percentage of
  assets that may be invested in U.S. Treasury bills, notes, or other
  obligations issued or guaranteed by the U.S. Government, its agencies or
  instrumentalities or repurchase agreements secured by such obligations.
 
    2. Purchase any securities which would cause more than 25% of such Fund's
  total assets at the time of purchase to be invested in securities of one or
  more issuers conducting their principal business activities in the same
  industry; provided that (a) there is no limitation with respect to obligations
  issued or guaranteed by the U.S. Government, its agencies or instrumentalities
  and repurchase agreements secured by such obligations; (b) wholly owned
  finance companies will be considered to be in the industries of their parents
  if their activities are primarily related to financing the activities of their
  parents; and (c) utilities will be divided according to their services. For
  example, gas, gas transmission, electric and gas, electric,
 
                                       20
<PAGE>   21
 
  and telephone will each be considered a separate industry.
   
    3. Borrow money or issue senior securities except as and to the extent
  permitted by the 1940 Act or any rule, order or interpretation thereunder. So
  long as the Money Market Fund's borrowings, including reverse repurchase
  agreements and dollar roll agreements, exceed 5% of such Fund's total assets,
  the Money Market Fund will not acquire any portfolio securities.
    
    4. Make loans, except that each Fund may purchase or hold debt instruments
  and lend portfolio securities in accordance with its investment objective and
  policies, make time deposits with financial institutions, and enter into
  repurchase agreements.
 
  The following additional investment restrictions, as to a particular Fund, may
be changed without the vote of a majority of the outstanding Shares of such
Fund:
 
     1. The Money Market Fund will not purchase or otherwise acquire any
  security, if, as a result, more than 10% of its net assets would be invested
  in securities that are illiquid.
 
    2. Each of the other Funds will not purchase or otherwise acquire any
  security, if, as a result, more than 15% of its net assets would be invested
  in securities that are illiquid.
 
  For purposes of this investment restriction, illiquid securities include
securities which are not readily marketable and repurchase agreements with
maturities in excess of seven days.
 
  In addition to the above investment restrictions, each Fund is subject to
certain other investment restrictions set forth under "INVESTMENT OBJECTIVES AND
POLICIES--Investment Restrictions" in the Funds' Statement of Additional
Information.
 
  Irrespective of fundamental investment restriction number 1 above, and
pursuant to Rule 2a-7 under the 1940 Act, the Money Market Fund will, with
respect to 100% of its total assets, limit its investment in the securities of
any one issuer in the manner provided by such Rule, which limitations are
referred to above under the caption "INVESTMENT OBJECTIVES AND POLICIES--The
Money Market Fund."
 
                              VALUATION OF SHARES
   
  The net asset value of the Money Market Fund is determined and its Shares are
priced as of 12:00 noon (Eastern time) and the close of regular trading on the
New York Stock Exchange (the "Exchange") (generally 4:00 p.m. Eastern time) on
each Business Day of the Money Market Fund. The net asset value of each of the
other Funds is determined and their Shares are priced as of the close of regular
trading on the Exchange on each Business Day. The time or times at which the
Shares of a Fund are priced are hereinafter referred to as the "Valuation Time"
or "Valuation Times," as the case may be. A "Business Day" of a Fund is a day on
which the Exchange is open for trading and any other day (other than a day on
which no Shares of that Fund are tendered for redemption and no order to
purchase any Shares of that Fund is received) during which there is sufficient
trading in portfolio instruments such that such Fund's net asset value per share
might be materially affected. The Exchange will not be open in observance of the
following holidays: New Year's Day, President's Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving and Christmas. Net asset value per
share for purposes of pricing purchases and redemptions is calculated by
dividing the value of all securities and other assets belonging to a Fund, less
the liabilities charged to that Fund, by the number of that Fund's outstanding
Shares.
    
  The net asset value per share for each of the Funds, other than the Money
Market Fund, will fluctuate as the value of the investment portfolio of a Fund
changes. The Board of Trustees of the Group has set the initial price per Share
for each
 
                                       21
<PAGE>   22
   
of the Funds, other than the Money Market Fund, at $10.00.
    
  The assets in the Money Market Fund are valued based upon the amortized cost
method which the Trustees of the Group believe fairly reflects the market-based
net asset value per share. Pursuant to the rules and regulations of the
Commission regarding the use of the amortized cost method, the Money Market Fund
will maintain a dollar-weighted average portfolio maturity of 90 days or less.
Although the Group seeks to maintain the Money Market Fund's net asset value per
share at $1.00, there can be no assurance that net asset value will not vary.
 
  The portfolio securities in each of the other Funds for which market
quotations are readily available are valued based upon their current available
prices in the principal market in which such securities normally are traded.
Unlisted securities for which market quotations are readily available are valued
at such market values. Other securities, including restricted securities and
other securities for which market quotations are not readily available, and
other assets are valued at fair value by the Adviser under procedures
established by, and under the supervision of the Group's Board of Trustees.
Securities may be valued by an independent pricing service approved by the
Group's Board of Trustees. Investments in debt securities with remaining
maturities of 60 days or less may be valued based upon the amortized cost
method. For further information about valuation of investments, see "NET ASSET
VALUE" in the Statement of Additional Information.
 
                       HOW TO PURCHASE AND REDEEM SHARES
 
DISTRIBUTOR
 
  Shares in each Fund are sold on a continuous basis by the Group's distributor,
BISYS (the "Distributor"). The principal office of the Distributor is 3435
Stelzer Road, Columbus, Ohio 43219. If you wish to purchase Shares, telephone
the Group at (800) 766-8938.
 
PURCHASES OF SHARES
 
  Shares may be purchased through procedures established by the Distributor in
connection with the requirements of qualified accounts maintained by or on
behalf of certain persons ("Customers") by the Adviser or its correspondent or
affiliated banks (collectively, the "Banks"). These procedures may include
instructions under which a Customer's account is "swept" automatically no less
frequently than weekly and amounts in excess of a minimum amount agreed upon by
the Bank and the Customer are invested by the Distributor in Shares of a
particular Fund, depending upon the type of the Customer's account and/or the
instructions of the Customer.
 
  Shares of the Funds sold to the Banks acting in a fiduciary, advisory,
custodial, agency, or other similar capacity on behalf of Customers will
normally be held of record by the Banks. With respect to Shares of the Funds so
sold, it is the responsibility of the particular Bank to transmit purchase or
redemption orders to the Distributor and to deliver federal funds for purchase
on a timely basis. Beneficial ownership of Shares will be recorded by the Banks
and reflected in the account statements provided by the Banks to Customers. A
Bank will exercise voting authority for those Shares for which it is granted
authority by the Customer.
 
  Investors may also purchase Shares of a Fund by completing and signing an
Account Registration Form and mailing it, together with a check (or other
negotiable bank draft or money order) in at least the minimum initial purchase
amount, payable to the appropriate Fund, to the 1st Source Monogram Funds, P.O.
Box 182084, Columbus, Ohio 43218-2084. Subsequent purchases of Shares of that
Fund may be made at any time by mailing a check (or other negotiable bank draft
or money order) payable to the Group, to the above address.
 
  If an Account Registration Form has been previously received by the Group,
investors
 
                                       22
<PAGE>   23
 
may also purchase Shares by wiring funds to the Funds' custodian. Prior to
wiring any such funds and in order to ensure that wire orders are invested
promptly, investors must call the Group at (800) 766-8938 to obtain instructions
regarding the bank account number into which the funds should be wired and other
pertinent information.
 
  Shares of each Fund are purchased at the net asset value per share (see
"VALUATION OF SHARES") next determined after receipt by the Distributor, its
agents or broker-dealers with whom it has an agreement of an order in good form
to purchase Shares plus any applicable sales charge as described below.
Purchases of Shares of a Fund will be effected only on a Business Day (as
defined in "VALUATION OF SHARES") of that Fund.
   
  An order to purchase Shares of the Money Market Fund will be deemed to have
been received by the Distributor only when federal funds with respect thereto
are available to the Money Market Fund's custodian for investment. Federal funds
are monies credited to a bank's account with a Federal Reserve Bank. Payment for
an order to purchase Shares of the Money Market Fund which is transmitted by
federal funds wire will be available the same day for investment by the Money
Market Fund's custodian, if received prior to the last Valuation Time (see
"VALUATION OF SHARES"). Payments transmitted by other means (such as by check
drawn on a member of the Federal Reserve System) will normally be converted into
federal funds within two banking days after receipt. The Group strongly
recommends that investors of substantial amounts use federal funds to purchase
Shares. Shares of the Money Market Fund purchased before 12:00 noon, Eastern
Time, begin earning dividends on the same Business Day. Shares of the Money
Market Fund purchased after 12:00 noon, Eastern Time, begin earning dividends on
the next Business Day. All Shares of the Money Market Fund continue to earn
dividends through the day before their redemption.
 
  For orders for the purchase of Shares of any of the other Funds placed through
a broker-dealer, the applicable public offering price will be the net asset
value as so determined (plus any applicable sales charge), but only if the
broker-dealer receives the order and transmits it to the Distributor prior to
the Valuation Time for that day. The broker-dealer is responsible for
transmitting such orders by the Valuation Time. If the broker-dealer fails to do
so, the investor's right to that day's closing price must be settled between the
investor and the broker-dealer. If the broker-dealer receives the order after
the Valuation Time for that day, the price will be based on the net asset value
determined as of the Valuation Time for the next Business Day.
    
MINIMUM INVESTMENT
 
  Except as otherwise discussed below under "Auto Invest Plan," the minimum
investment is $1,000 for the initial purchase of Shares of a Fund by an investor
and $25 for subsequent purchases of Shares of that Fund. The initial purchase
minimum is $250 for employees of the Adviser or any of its affiliates and is
waived for such employees if purchases are made in connection with an Individual
Retirement Account ("IRA").
   
  Depending upon the terms of a particular Customer's account, the Banks or
their affiliates may charge a Customer account fees for automatic investment and
other cash management services provided in connection with an investment in a
Fund. Information concerning these services and any charges will be provided by
the Banks. This Prospectus should be read in conjunction with any such
information received from the Banks or their affiliates.
    
  Each Fund reserves the right to reject any order for the purchase of its
Shares in whole or in part, including purchases made with foreign
 
                                       23
<PAGE>   24
 
checks and third party checks not originally made payable to the order of the
investor.
 
  Every Shareholder will receive a confirmation of each new transaction in his
or her account, which will also show the total number of Shares owned by the
Shareholder and the number of Shares being held in safekeeping by the Transfer
Agent for the account of the Shareholder. Reports of purchases and redemptions
of Shares by Banks on behalf of their Customers will be sent by the Banks to
their Customers. Shareholders may rely on these statements in lieu of
certificates. Certificates representing Shares will not be issued.
 
1ST SOURCE MONOGRAM INDIVIDUAL RETIREMENT ACCOUNT ("IRA")
 
  A 1st Source Monogram IRA enables individuals, even if they participate in an
employer-sponsored retirement plan, to establish their own retirement program.
1st Source Monogram IRA contributions may be tax-deductible and earnings are tax
deferred. Under the Tax Reform Act of 1986, the tax deductibility of IRA
contributions is restricted or eliminated for individuals who participate in
certain employer pension plans and whose annual income exceeds certain limits.
Existing IRAs and future contributions up to the IRA maximums, whether
deductible or not, still earn income on a tax-deferred basis.
 
  All 1st Source Monogram IRA distribution requests must be made in writing to
the Distributor. Any deposits to a 1st Source Monogram IRA must distinguish the
type and year of the contributions.
 
  For more information on the 1st Source Monogram IRAs call the Group at (800)
766-8938. Investment in Shares of the Intermediate Tax-Free Fund or any other
tax-exempt fund would not be appropriate for a 1st Source Monogram IRA.
Shareholders are advised to consult a tax adviser on 1st Source Monogram IRA
contribution and withdrawal requirements and restrictions.
 
AUTO INVEST PLAN
   
  The 1st Source Monogram Funds Auto Invest Plan enables Shareholders to make
regular monthly or quarterly purchases of Shares of a Fund through automatic
deduction from their bank accounts, provided that the Shareholder's bank is a
member of the Federal Reserve and the Automated Clearing House (ACH) system.
With Shareholder authorization the Transfer Agent will deduct the amount
specified (subject to the applicable minimums) from the Shareholder's bank
account which will automatically be invested in Shares of the designated Fund at
the public offering price next determined after receipt of payment by the
Transfer Agent. The required minimum initial investment when opening an account
using the Auto Invest Plan is $25 ($250 if purchases are in connection with an
IRA unless the purchaser is an employee of the Adviser in which case the minimum
in connection with an IRA is waived); the minimum amount for subsequent
investments is $25. To participate in the Auto Invest Plan, Shareholders should
complete the appropriate section of the Account Registration Form or a
supplemental sign-up form which can be acquired by calling the Group at (800)
766-8938. For a Shareholder to change the Auto Invest instructions, the request
must be made in writing to the Group at: 3435 Stelzer Road, Columbus, Ohio
43219.
 
  The Group may eliminate or change the Auto Invest Plan at any time or from
time to time without notice thereof.
 
SALES CHARGES
 
  The public offering price of Shares of each of the Funds, other than the Money
Market Fund, equals net asset value plus a sales charge in accordance with the
tables below. BISYS receives this sales charge as Distributor and reallows a
portion of it as dealer discounts and brokerage commissions. However, the
Distributor, in its sole discretion, may pay certain dealers all or part of the
portion of the sales
    
 
                                       24

charge it receives. The broker or dealer who receives a reallowance in excess of
90% of the sales charge may be deemed to be an "underwriter" for purposes of the
1933 Act.
 
  There is no sales charge imposed by the Money Market Fund in connection with
the purchase of its Shares.

  From time to time dealers who receive dealer discounts and brokerage
commissions from the Distributor may reallow all or a portion of such dealer
discounts and brokerage commissions to other dealers or brokers. The
Distributor, at its own expense, will also provide additional compensation to
dealers in connection with sales of Shares of any of the Funds. Such
compensation will include financial assistance to dealers in connection with
conferences, sales or training programs for their employees, seminars for the
public, advertising campaigns regarding one of more funds of the Group, and/or
other dealer-sponsored special events. In some instances, this compensation will
be made available only to certain dealers whose representatives have sold a
significant amount of such Shares. Compensation will include payment for travel
expenses, including lodging, incurred in connection with trips taken by invited
registered representatives and members of their families to locations within or
outside of the United States for meetings or seminars of a business nature. 
Compensation will also include the following types of non-cash compensation
offered through sales contests: (1) vacation trips, including the provision of
travel arrangements and lodging at luxury resorts at an exotic location, (2)
tickets for entertainment events (such as concerts, cruises and sporting
events) and (3) merchandise (such as clothing, trophies, clocks and pens).
Dealers may not use sales of a Fund's Shares to qualify for this compensation
to the extent such may be prohibited by the laws of any state or any
self-regulatory agency, such as the NASD. None of the aforementioned 
compensation is paid for by any Fund or its Shareholders.
 
SALES CHARGE WAIVERS
 
  The Distributor may waive sales charges for the purchase of Shares of a Fund
by or on behalf of:
 
  (1) Accounts for which FSC, the Adviser, banks and trust companies or one of
their affiliates acts in a fiduciary, advisory, agency,
 
                                       25
<PAGE>   26
 
custodial (other than for individual retirement accounts), or similar capacity;
 
  (2) Officers, trustees, directors, employees and retired employees (including
spouses and children under the age of 21 of the foregoing) of FSC, the Adviser,
the Group, BISYS and any affiliates thereof;
 
  (3) Purchasers pursuant to the terms of a payroll deduction plan, a 401(k)
plan or a 403(b) plan which by its terms permits purchases of Shares of the
Funds;
 
  (4) Purchasers using solely the proceeds from a distribution from the Adviser
or an affiliate trust, fiduciary or agency account (this waiver only applies to
the initial purchase of Shares with such proceeds);
 
  (5) Brokers, dealers and agents for their own account who have a sales
agreement with the Distributor, and their employees (and their spouses and
children under the age of 21);
 
  (6) Orders placed on behalf of other investment companies distributed by The
BISYS Group, Inc. or its affiliated companies, including the Distributor;
 
  (7) Investment advisers or financial planners regulated by a federal or state
governmental authority who are purchasing Shares for their own account or for an
account for which they are authorized to make investment decisions (i.e., a
discretionary account) and who charge a management, consulting or other fee for
their services, and clients of such investment advisers or financial planners
who place trades for their own accounts if the accounts are linked to the master
account of such investment adviser or financial planner on the books and records
of a broker or agent; and
 
  (8) Investors purchasing Shares with proceeds from a redemption of shares of
another open-end investment company (other than the Group) on which a sales
charge was paid if (i) such redemption occurred with sixty (60) days prior to
the date of the purchase order and (ii) satisfactory evidence of the purchaser's
eligibility is provided to the Distributor at the time of purchase (e.g., a
confirmation of the redemption).
   
  The Distributor may change or eliminate the foregoing waivers at any time or
from time to time without notice thereof. The Distributor may also periodically
waive all or a portion of the sales charge for all investors with respect to a
Fund.
    
CONCURRENT PURCHASES
   
  For purposes of qualifying for a lower sales charge, investors have the
privilege of combining concurrent purchases of a Fund and one or more of the
other funds of the Group sold with a sales charge and advised by the Adviser
("1st Source Monogram Load Funds"). For example, if a Shareholder concurrently
purchases Shares in the Diversified Equity Fund at the total public offering
price of $25,000 and Shares in the Income Equity Fund at the total public
offering price of $30,000, the sales charge would be that applicable to a
$55,000 purchase as shown in the table above. This privilege, however, may be
modified or eliminated at any time or from time to time by the Group without
notice thereof.
 
LETTER OF INTENT
 
  An investor may obtain a reduced sales charge by means of a written Letter of
Intent which expresses the intention of such investor to purchase Shares of a
1st Source Monogram Load Fund at a designated total public offering price within
a designated 13-month period. Each purchase of Shares under a Letter of Intent
will be made at the net asset value plus the sales charge applicable at the time
of such purchase to a single transaction of the total dollar amount indicated in
the Letter of Intent. A Letter of Intent may include purchases of Shares made
not more than 90 days prior to the date such investor signs a Letter of Intent;
however, the 13-month period during which
    
 
                                       26
<PAGE>   27
   
the Letter of Intent is in effect will begin on the date of the earliest
purchase to be included. This program may be modified or eliminated at any time
or from time to time by the Group without notice. For further information about
letters of intent, interested investors should contact the Group at (800)
766-8938.
    
  A Letter of Intent is not a binding obligation upon the investor to purchase
the full amount indicated. The minimum initial investment under a Letter of
Intent is 5% of such amount. Shares purchased with the first 5% of such amount
will be held in escrow (while remaining registered in the name of the investor)
to secure payment of the higher sales charge applicable to the Shares actually
purchased if the full amount indicated is not purchased, and such escrowed
Shares will be involuntarily redeemed to pay the additional sales charge, if
necessary. Dividends on escrowed Shares, whether paid in cash or reinvested in
additional Shares, are not subject to escrow. The escrowed Shares will not be
available for disposal by the investor until all purchases pursuant to the
Letter of Intent have been made or the higher sales charge has been paid. When
the full amount indicated has been purchased, the escrow will be released. An
adjustment will be made to reflect any reduced sales charge applicable to Shares
purchased during the 90-day period prior to the date the Letter of Intent was
entered into at the conclusion of the 13-month period and in the form of
additional Shares credited to the Shareholder's account at the then current
public offering price applicable to a single purchase of the total amount of the
total purchases. Additionally, if the total purchases within the 13-month period
exceed the amount specified, a similar adjustment will be made to reflect
further reduced sales charges applicable to such purchases.
 
RIGHT OF ACCUMULATION
   
  Pursuant to the right of accumulation, investors are permitted to purchase
Shares of a 1st Source Monogram Load Fund at the public offering price
applicable to the total of (a) the total public offering price of the Shares of
the 1st Source Monogram Load Fund then being purchased plus (b) an amount equal
to the then current net asset value of the purchaser's combined holdings of the
Shares of all of the 1st Source Monogram Load Funds. The "purchaser's combined
holdings" described in the preceding sentence shall include the combined
holdings of the purchaser, the purchaser's spouse and children under the age of
21 and the purchaser's retirement plan accounts. To receive the applicable
public offering price pursuant to the right of accumulation, Shareholders must,
at the time of purchase, give the Transfer Agent sufficient information to
permit confirmation of qualification. This right of accumulation, however, may
be modified or eliminated at any time or from time to time by the Group without
notice.
 
EXCHANGE PRIVILEGE
 
  Shares of a 1st Source Monogram Load Fund may be exchanged for Shares of any
of the other 1st Source Monogram Load Funds at respective net asset values upon
the payment of a sales charge equal to the difference, if any, between the sales
charge payable upon purchase of Shares of such 1st Source Monogram Load Fund and
the sales charge previously paid on the Fund Shares to be exchanged. When Shares
of the Money Market Fund are exchanged for Shares of a 1st Source Monogram Load
Fund, the applicable sales load will be assessed, unless such Shares to be
exchanged were acquired through a previous exchange for Shares on which a sales
charge was paid. Under such circumstances, the Shareholder must notify the Group
that a sales charge was originally paid and provide the Group with sufficient
information to permit confirmation of the Shareholder's right not to pay a sales
charge or to pay a reduced sales charge. Provided further, that with respect to
every exchange, the amount to be exchanged must meet the applicable minimum
investment requirements and
    
 
                                       27
<PAGE>   28
 
the exchange is made in states where it is legally authorized.
 
  An exchange is considered a sale of Shares for federal income tax purposes.
However, a Shareholder may not include any sales charge on Shares of a 1st
Source Monogram Load Fund as a part of the cost of those Shares for purposes of
calculating the gain or loss realized on an exchange of those Shares within 90
days of their purchase.
 
  The Group may at any time modify or terminate the foregoing exchange
privileges. The Group, however, will give shareholders 60 days' advance written
notice of any such modification.
 
  A Shareholder wishing to exchange his or her Shares may do so by contacting
the Group at (800) 766-8938 or by providing written instructions to the Group.
Any Shareholder who wishes to make an exchange should obtain and review the
current prospectus of the Fund in which he or she wishes to invest before making
the exchange. For a discussion of risks associated with unauthorized telephone
exchanges, see "Redemption by Telephone" below.
 
REDEMPTION OF SHARES
 
  Shares may ordinarily be redeemed by mail or by telephone. However, all or
part of a Customer's Shares may be redeemed in accordance with instructions and
limitations pertaining to his or her account at a Bank. For example, if a
Customer has agreed with a Bank to maintain a minimum balance in his or her
account with the Bank, and the balance in that account falls below that minimum,
the Customer may be obliged to redeem, or the Bank may redeem on behalf of the
Customer, all or part of the Customer's Shares of a Fund to the extent necessary
to maintain the required minimum balance.
 
Redemption by Mail
 
  A written request for redemption must be received by the Group, at the address
shown on the front page of this Prospectus, in order to honor the request. The
Transfer Agent will require a signature guarantee by an eligible guarantor
institution. The signature guarantee requirement will be waived if the following
conditions apply: (1) the redemption check is payable to the Shareholder(s) of
record, and (2) the redemption check is mailed to the Shareholder(s) at the
address of record or mailed or wired to a commercial bank account previously
designated on the Account Registration Form. There is no charge for having
redemption proceeds mailed to a designated bank account. To change the address
to which a redemption check is to be mailed, a written request therefor must be
received by the Transfer Agent. In connection with such request, the Transfer
Agent will require a signature guarantee by an eligible guarantor institution.
For purposes of this policy, the term "eligible guarantor institution" shall
include banks, brokers, dealers, credit unions, securities exchanges and
associations, clearing agencies and savings associations as those terms are
defined in the Securities Exchange Act of 1934. The Transfer Agent reserves the
right to reject any signature guarantee if (1) it has reason to believe that the
signature is not genuine, (2) it has reason to believe that the transaction
would otherwise be improper, or (3) the guarantor institution is a broker or
dealer that is neither a member of a clearing corporation nor maintains net
capital of at least $100,000.
 
Redemption by Telephone
 
  If a Shareholder has so designated on the Account Registration Form, a
Shareholder may request a redemption of his or her Shares by telephoning the
Group and having the payment of redemption requests sent electronically directly
to a domestic commercial bank account previously designated by the Shareholder
on the Account Registration Form or mailed di-
 
                                       28
<PAGE>   29
   
rectly to the Shareholder at the Shareholder's address as recorded by the
Transfer Agent. Under most circumstances, such payments will be transmitted on
the next Business Day following receipt of a valid request for redemption. Such
wire redemption requests may be made by the Shareholder by telephone to the
Group. The Group may reduce the amount of a wire redemption payment by the
then-current wire redemption charge of the Funds' custodian. There is currently
no charge for having payment of redemption requests mailed or sent
electronically to a designated bank account. For telephone redemptions, call the
Group at (800) 766-8938.
 
  Neither the Funds nor their service providers will be liable for any loss,
damages, expense or cost arising out of any telephone redemption effected in
accordance with a Fund's telephone redemption procedures, acting upon
instructions reasonably believed to be genuine. Each Fund will employ procedures
designed to provide reasonable assurance that instructions by telephone are
genuine; if these procedures are not followed, such Fund or its service
providers may be liable for any losses due to unauthorized or fraudulent
instructions. These procedures include recording all phone conversations,
sending confirmations to Shareholders within 72 hours of the telephone
transaction, verification of account name and account number or tax
identification number, and sending redemption proceeds only to the address of
record or to a previously authorized bank account. If, due to temporary adverse
conditions, Shareholders are unable to effect telephone transactions,
Shareholders may also mail the redemption request to the Group at the address
shown on the front page of this Prospectus.
    
AUTO WITHDRAWAL PLAN
 
  The Auto Withdrawal Plan enables Shareholders of a Fund, with an account
balance in such Fund of $5,000 or more, to make regular monthly or quarterly
redemptions of Shares. With Shareholder authorization, the Transfer Agent will
automatically redeem Shares at the net asset value on the dates of the
withdrawal and have a check in the amount specified mailed to the Shareholder.
The required minimum withdrawal is $25 monthly. To participate in the Auto
Withdrawal Plan, Shareholders should call (800) 766-8938 for more information.
Purchases of additional Shares concurrent with withdrawals may be
disadvantageous to certain Shareholders because of tax liabilities and sales
charges. For a Shareholder to change the Auto Withdrawal instructions, the
request must be made in writing to the Group.
 
PAYMENTS TO SHAREHOLDERS
 
  Redemption orders are effected at the net asset value per share next
determined after the Shares are properly tendered for redemption, as described
above. Payment to Shareholders for Shares redeemed will be made within seven
days after receipt by the Distributor of the request for redemption. However,
with respect to the Money Market Fund, to the greatest extent possible, such
Fund will attempt to honor requests from Shareholders for same day payments upon
redemption of Shares if the request for redemption is received by the
Distributor before 12:00 noon, Eastern Time, on a Business Day or, if the
request for redemption is received after 12:00 noon, Eastern Time, to honor
requests for payment on the next Business Day. With respect to each of the other
Funds, to the greatest extent possible, such Funds will attempt to honor
requests from Shareholders for next day payments upon redemption of Shares if
the request for redemption is received by the Distributor before the Valuation
Time, on a Business Day or, if the request for redemption is received after the
Valuation Time, to honor requests for payment on the second Business Day. Each
Fund will attempt to so honor redemption requests unless it would be
disadvantageous to that Fund or the Shareholders of that Fund to sell or
liquidate
 
                                       29
<PAGE>   30
 
portfolio securities in an amount sufficient to satisfy requests for payments in
that manner.
 
  At various times, the Group may be requested to redeem Shares for which it has
not yet received good payment. In such circumstances, the Group may delay the
forwarding of proceeds for up to 15 days or more until payment has been
collected for the purchase of such Shares. With respect to Shares of the Money
Market Fund, during the period of any such delay, such Shares to be redeemed
would continue to receive daily dividends as declared until execution of the
redemption. The Group intends to pay cash for all Shares redeemed, but under
abnormal conditions which make payment in cash unwise, the Group may make
payment wholly or partly in portfolio securities at their then market value
equal to the redemption price. In such cases, an investor may incur brokerage
costs in converting such securities to cash.
 
  Due to the relatively high cost of handling small investments, each Fund
reserves the right to redeem, at net asset value, the Shares of that Fund of any
Shareholder if, because of redemptions of Shares by or on behalf of the
Shareholder (but not as a result of a decrease in the market price of such
Shares, the deduction of any sales charge or the establishment of an account by
an employee of the Adviser or one of its affiliates or by using the Auto Invest
Plan), the account of such Shareholder has a value of less than $1,000.
Accordingly, an investor purchasing Shares of a Fund in only the minimum
investment amount may be subject to such involuntary redemption if he or she
thereafter redeems some of his or her Shares. Before a Fund exercises its right
to redeem such Shares and to send the proceeds to the Shareholder, the
Shareholder will be given notice that the value of the Shares in his or her
account is less than the minimum amount and will be allowed not less than 60
days to make an additional investment in an amount which will increase the value
of the account to at least $1,000.
 
  See "ADDITIONAL PURCHASE AND REDEMPTION INFORMATION" and "NET ASSET VALUE" in
the Statement of Additional Information for examples of when the Group may
suspend the right of redemption or redeem shares involuntarily in light of the
Group's responsibilities under the 1940 Act.
 
                              DIVIDENDS AND TAXES
 
DIVIDENDS
 
  The net income of the Money Market Fund is declared daily and generally paid
monthly on the first Business Day of the following month. However, from time to
time such dividends may be paid on the last Business Day of the preceding month.
 
  A dividend for each of the other Funds, other than the Special Equity Fund, is
declared monthly at the close of business on the day of declaration and is
generally paid monthly. A dividend for the Special Equity Fund is declared
quarterly at the close of business on the day of declaration and is generally
paid quarterly. Each such dividend consists of an amount of accumulated
undistributed net income of that Fund as determined necessary or appropriate by
the appropriate officers of the Group.
 
  Shareholders will automatically receive all income dividends and capital gains
distributions in additional full and fractional Shares of that particular Fund
at the net asset value as of the date of payment, unless the Shareholder elects
to receive dividends or distributions in cash. Such election, or any revocation
thereof, must be made in writing to the Transfer Agent at 3435 Stelzer Road,
Columbus, Ohio 43219, and will become effective with respect to dividends and
distributions having record dates after its receipt by the Transfer Agent.
 
  Distributable net realized capital gains for each Fund are distributed at
least annually. Dividends are paid in cash not later than seven
 
                                       30
<PAGE>   31
 
Business Days after a Shareholder's complete redemption of his or her Shares in
a Fund.
 
  If a Shareholder elects to receive distributions in cash, and checks (1) are
returned and marked as "undeliverable" or (2) remain uncashed for six months,
the Shareholder's cash election will be changed automatically and future
dividend and capital gains distributions will be reinvested in that Fund at the
per share net asset value determined as of the date of payment of the
distribution. In addition, any undeliverable checks or checks that remain
uncashed for six months will be canceled and will be reinvested in that Fund at
the per share net asset value determined as of the date of cancellation.
 
FEDERAL TAXES
 
  General. Each of the Funds is treated as a separate entity for federal income
tax purposes and intends to qualify as a "regulated investment company" under
the Internal Revenue Code of 1986 (the "Code") for so long as such qualification
is in the best interest of that Fund's Shareholders. Qualification as a
regulated investment company under the Code requires, among other things, that
the regulated investment company distribute to its shareholders at least 90% of
its investment company taxable income. Each Fund contemplates declaring as
dividends all or substantially all of that Fund's investment company taxable
income (before deduction of dividends paid).
 
  A non-deductible 4% excise tax is imposed on regulated investment companies
that do not distribute in each calendar year (regardless of whether they
otherwise have a non-calendar taxable year) an amount equal to 98% of their
ordinary income for the calendar year plus 98% of their capital gain net income
for the one-year period ending on October 31 of such calendar year. If
distributions during a calendar year were less than the required amount, that
Fund would be subject to a nondeductible 4% excise tax on the deficiency.
   
  It is expected that each Fund will distribute annually to Shareholders all or
substantially all of that Fund's net ordinary income and net realized capital
gains and that, except as discussed below with respect to the Intermediate
Tax-Free Fund, such distributed net ordinary income and distributed net realized
capital gains will be taxable income to Shareholders for federal income tax
purposes, even if paid in additional Shares of the Fund and not in cash. The
dividends-received deduction for corporations will apply to the aggregate of
such ordinary income distributions in the same proportion as the aggregate
dividends eligible for the dividends deduction, if any, received by the Fund
bear to its gross income. Since all of the Money Market Fund's, the Income
Fund's and the Intermediate Tax-Free Fund's net investment income is expected to
be derived from earned interest and short-term capital gains, it is anticipated
that no part of any distribution from such Funds will be eligible for the
dividends received deduction for corporation. The Money Market Fund also does
not expect to realize any long-term capital gains and, therefore, does not
foresee paying any "capital gains dividends" as described in the Code.
    
  Distribution by a Fund of the excess of net long-term capital gain over net
short-term capital loss is taxable to Shareholders as long-term capital gain in
the year in which it is received, regardless of how long the Shareholder has
held the Shares. Such distributions are not eligible for the dividends-received
deduction.
 
  If the net asset value of a Share is reduced below the Shareholder's cost of
that Share by the distribution of income or gain realized on the sale of
securities, the distribution, from a practical stand point, is a return of
invested principal, although taxable as described above.
 
  Prior to purchasing Shares, the impact of dividends or capital gains
distributions which are expected to be declared or have been declared, but have
not been paid, should be care-
 
                                       31
<PAGE>   32
 
fully considered. Any such dividends or capital gains distributions paid shortly
after a purchase of Shares prior to the record date will have the effect of
reducing the per share net asset value of the Shares by the amount of the
dividends or distributions. All or a portion of such dividends or distributions,
although in effect a return of capital, is subject to tax.
 
  Additional information regarding federal taxes is contained in the Statement
of Additional Information under the heading "ADDITIONAL INFORMATION--Addi-
tional Tax Information." However, the information contained in this Prospectus
and the additional material in the Statement of Additional Information are only
brief summaries of some of the important tax considerations generally affecting
the Funds and their Shareholders. Accordingly, potential investors are urged to
consult their tax advisers concerning the application of federal, state and
local taxes as such laws and regulations affect their own tax situation.
 
  Shareholders will be advised at least annually as to the federal and state
income tax consequences of distributions made to them during the year.
 
  The Intermediate Tax-Free Fund. The Intermediate Tax-Free Fund will distribute
substantially all of its net investment income and net capital gains to its
Shareholders. Dividends derived from interest earned on Exempt Securities
constitute "exempt-interest dividends" when designated as such by the
Intermediate Tax-Free Fund and will be excludable from gross income for federal
income tax purposes and is not expected to be treated as a preference item for
computing the alternative minimum tax.
 
  Distributions, if any, derived from capital gains will generally be taxable to
Shareholders as capital gains for federal income tax purposes to the extent so
designated by the Intermediate Tax-Free Fund. Dividends, if any, derived from
sources other than interest excluded from gross income for federal income tax
purposes and capital gains will be taxable to Shareholders as ordinary income
for federal income tax purposes whether or not reinvested in additional Shares.
Shareholders not subject to federal income tax on their income will not, of
course, be required to pay federal income tax on any amounts distributed to
them. The Intermediate Tax-Free Fund anticipates that substantially all of its
dividends will be excluded from gross income for federal income tax purposes.
The Intermediate Tax-Free Fund will notify each Shareholder annually of the tax
status of all distributions.
 
  If a Shareholder receives an exempt-interest dividend with respect to any
Share and such Share is held by the Shareholder for six months or less, any loss
on the sale or exchange of such Share will be disallowed to the extent of the
amount of such exempt-interest dividend. In certain limited instances, the
portion of Social Security benefits that may be subject to federal income
taxation, may be affected by the amount of tax-exempt interest income, including
exempt-interest dividends, received by a Shareholder.
   
  Interest on indebtedness incurred or continued by a Shareholder to purchase or
carry Shares of the Intermediate Tax-Free Fund is not deductible for federal
income tax purposes assuming the Intermediate Tax-Free Fund distributes
exempt-interest dividends during the Shareholder's taxable year. It is
anticipated that distributions from the Intermediate Tax-Free Fund will not be
eligible for the dividends received deduction for corporations.
    
STATE TAXES
 
  Even though a substantial portion of distributions of net income by the Money
Market Fund to its Shareholders will be attributable to interest on U.S.
Treasury obligations, which may be exempt from state or local tax if received
directly by a Shareholder, Shareholders of the Money Market Fund may be subject
to state
 
                                       32
<PAGE>   33
 
and local taxes with respect to their ownership of Shares or their receipt of
distributions from the Money Market Fund. In addition, to the extent
Shareholders receive distributions of income attributable to investments in
repurchase agreements by the Money Market Fund, such distributions may also be
subject to state or local taxes.
 
                            MANAGEMENT OF THE GROUP
 
TRUSTEES OF THE GROUP
   
  Overall responsibility for management of the Group rests with its Board of
Trustees. At any given time all Trustees of the Group may not have been elected
by shareholders of the Group. The Group will be managed by the Trustees in
accordance with the laws of Ohio governing business trusts. The Trustees, in
turn, elect the officers of the Group to supervise its day-to-day operations.
    
  The Trustees of the Group receive fees and are reimbursed for their expenses
in connection with each meeting of the Board of Trustees they attend. However,
no officer or employee of BISYS or BISYS Fund Services Inc., the sole general
partner of BISYS, receives any compensation from the Group for acting as a
Trustee of the Group. The officers of the Group receive no compensation directly
from the Group for performing the duties of their offices. BISYS receives fees
from the Group for acting as Administrator and under the Distribution Plan
discussed below, may receive fees under the Administrative Services Plan
discussed below, and may retain all or a portion of any sales load imposed upon
purchases of Shares. BISYS Fund Services, Inc. receives fees from each of the
Funds for acting as Transfer Agent and for providing certain fund accounting
services.
 
INVESTMENT ADVISER
 
  1st Source Bank, 100 North Michigan Street, South Bend, Indiana 46601, is the
investment adviser of each Fund. The Adviser is a wholly owned subsidiary of 1st
Source Corporation, a publicly held bank holding company ("FSC"). The Adviser
was founded in 1936, and while it has not previously served as an investment
adviser to an open-end management investment company, the Adviser and its
affiliates administer and manage, on behalf of their clients, trust assets which
as of March, 1996, totalled approximately $1.2 billion. Of such amount,
approximately $668 million are managed on behalf of personal trust customers and
approximately $500 million are managed on behalf of employee benefit plans. The
Adviser has over 60 years of banking experience and as of December 31, 1995,
had, on a consolidated basis with FSC, over $1.6 billion in assets.
 
  Subject to the general supervision of the Board of Trustees of the Group and
in accordance with the investment objectives and restrictions of the Funds, the
Adviser manages, makes decisions with respect to and places orders for all
purchases and sales of portfolio securities for the Money Market Fund, the
Income Equity Fund, the Special Equity Fund, the Income Fund and the
Intermediate Tax-Free Fund, and, through the Sub-Advisers, the Diversified
Equity Fund.
 
  For the services provided and expenses assumed pursuant to its investment
advisory agreement with the Group, the Adviser receives a fee from each of the
Funds, computed daily and paid monthly, at the following rates: with respect to
the Money Market Fund, the annual rate of thirty-five one-hundredths of one
percent (0.35%) of such Fund's average daily net assets; with respect to the
Diversified Equity Fund, the annual rate of one hundred ten one-hundredths of
one percent (1.10%) of such Fund's average daily net assets; with respect to the
Income Equity Fund, the annual rate of eighty one-hundredths of one percent
(0.80%) of such Fund's average daily net assets; with respect to the Special
Equity Fund, the annual rate of eighty one-hundredths of one percent (0.80%) of
such Fund's average
 
                                       33
<PAGE>   34
   
daily net assets; with respect to the Income Fund, the annual rate of fifty-five
one-hundredths of one percent (0.55%) of such Fund's average daily net assets;
and with respect to the Intermediate Tax-Free Fund, the annual rate of
fifty-five one-hundredths of one percent (0.55%) of such Fund's average daily
net assets. While the fees of the Adviser with respect to the Diversified
Equity, Special Equity and Income Equity Funds are higher than similar fees paid
by most mutual funds, the Board of Trustees believes such fees to be fair and
reasonable.
 
  The Adviser may periodically voluntarily reduce all or a portion of its
advisory fee with respect to a Fund to increase the net income of that Fund
available for distribution as dividends. The Adviser may not seek reimbursement
of such voluntarily reduced fees after the end of the fiscal year in which the
fees were reduced. The reduction of such fee will cause the yield and total
return of that Fund to be higher than they would otherwise be in the absence of
such a reduction.
    
  Ralph Shive is the portfolio manager of the Income Equity Fund. Mr. Shive has
served as Vice President and an investment officer of the Adviser since
September, 1989. Generally, Mr. Shive has worked as an analyst and portfolio

Turner has served as an investment officer of the Adviser since 1994. Prior
thereto and since October, 1986 he worked for IAA Trust Company, Bloomington,
Illinois, as a portfolio manager. Generally, Mr. Turner has worked as an analyst
and portfolio manager for 10 years after receiving his BS from Illinois State
University and a masters degree in management from Purdue University. As a

Adviser has entered into Sub-Investment Advisory Agreements with each of:
Miller, Anderson, One Tower Bridge, Suite 1100, West Conshohocken, Pennsylvania
19428; Loomis, 3 First National Plaza, Suite 5450, Chicago, Illinois 60600; and

                                       34
<PAGE>   35
   
reinvestment of a designated portion of the assets of the Diversified Equity
Fund, subject to the direction and control of the Group's Board of Trustees, and
the Adviser is responsible for selecting and monitoring each Sub-Adviser and
reporting the activities of each Sub-Adviser to the Company's Board of Trustees.
 
  Miller, Anderson is wholly owned by Morgan Stanley Group, Inc., 1585 Broadway,
New York, New York 10036. Miller, Anderson was founded in 1969 and was acquired
by Morgan Stanley Group, Inc. in 1995. Miller, Anderson provides advice
primarily to institutions, including other investment companies, and currently
has approximately $35 billion in assets under management, of which approximately
$2.4 billion is managed using Miller Anderson's value style as described above.
Robert J. Marcin, CFA, is primarily responsible for the day-to-day management of
that portion of the Diversified Equity Fund's portfolio managed by Miller
Anderson. Mr. Marcin has been a Partner with Miller Anderson since 1994, and has
had more than 14 years of investment experience.
 
  Loomis is a limited partnership, the sole general partner of which is Loomis,
Sayles & Company, Incorporated, One Financial Center, Boston, Massachusetts
02111. All of the outstanding shares of Loomis, Sayles & Company, Incorporated
are owned by New England Investment Companies, L.P., a publicly-traded limited
partnership ("NEIC"). NEIC's sole corporate general partner is owned by the New
England Mutual Life Insurance Company, which has announced its intention to
merge with and into Metropolitan Life Insurance Company ("MET"). MET will, after
the merger is effective, be the ultimate indirect parent of Loomis. Loomis was
founded in 1926 and has approximately $45 billion in assets under management.
The Chicago office of Loomis was founded in 1952, and has currently
approximately 62 clients and $3 billion in assets under management. Jerry
Castellini is primarily responsible for the day-to-day management of that
portion of the Diversified Equity Fund's portfolio managed by Loomis. Mr.
Castellini has been Managing Partner of Loomis since January, 1994, a Director
since February, 1995 and has had more than 16 years of investment experience.
 
  Columbus, a general partnership formed on September 9, 1994, is registered as
an investment adviser under the Investment Advisers Act of 1940 and acquired the
business operated by Columbus' predecessor since 1975. PIMCO Advisors L.P.
("PIMCO") and Columbus Circle Investors Management Inc. ("CCI"), a wholly owned
subsidiary of PIMCO, are the general partners of Columbus. Columbus serves as
sub-adviser to other mutual funds and also advises and manages individual
accounts, profit sharing and pension funds and institutional accounts. PIMCO's
general partner is a general partnership with two partners: (i) an indirect
wholly owned subsidiary of Pacific Mutual Life Insurance Company; and (ii) PIMCO
Partners, L.L.C., a limited liability company, all of the interests of which are
held directly by the 11 managing directors of Pacific Investment Management
Company, a subsidiary of PIMCO.
 
  Columbus currently has approximately $13 billion in assets under management,
of which approximately $8 billion is managed using the sector rotation style of
management (known as Positive Momentum & Positive Surprise) described above.
Although Columbus operates on a team style management basis, Daniel S. Pickett,
CFA, is primarily responsible for the day-to-day management of that portion of
the Diversified Equity Fund's portfolio managed by Columbus. Mr. Pickett has
been with Columbus since June, 1988, and a Managing Director of Columbus since
1994, and has had more than 11 years of investment experience.
    
  For its services provided and expenses assumed pursuant to its Sub-Investment
Advisory Agreement with the Adviser, each of Miller, Anderson, Loomis and
Columbus receives
 
                                       35
<PAGE>   36
 
from the Adviser a fee (computed daily and paid monthly as a percentage of that
portion of the Diversified Equity Fund's average daily net assets managed by
that Sub-Adviser) at the following annual rates: for Miller Anderson, 0.625% up
to $25,000,000 and 0.375% of the excess over $25,000,000; for Loomis, 0.65% up
to $5,000,000 and 0.50% of the excess over $5,000,000; and for Columbus, 1.00%
up to $10,000,000 and 0.50% of the excess over $10,000,000.
 
ADMINISTRATOR AND DISTRIBUTOR
 
  BISYS is the administrator for each Fund and also acts as each Fund's
principal underwriter and distributor (the "Administrator" or the "Distributor,"
as the context indicates). BISYS and its affiliated companies, including BISYS
Fund Services, Inc., are wholly owned by The BISYS Group, Inc., a publicly-held
company which is a provider of information processing, loan servicing and 401(k)
administration and recordkeeping services to and through banking and other
financial organizations.
   
  The Administrator generally assists in all aspects of a Fund's administration
and operation. For expenses assumed and services provided as administrator
pursuant to its management and administration agreement with the Group, the
Administrator receives a fee from each Fund equal to the lesser of a fee
computed daily and paid periodically, calculated at an annual rate of twenty
one-hundredths of one percent (0.20%) of that Fund's average daily net assets or
such other fee as may be agreed upon in writing by the Group and the
Administrator. The Administrator may periodically voluntarily reduce all or a
portion of its administration fee with respect to a Fund to increase the net
income of such Fund available for distribution as dividends. The Administrator
may not seek reimbursement of such reduced fees at a later date. The voluntary
reduction of such fee will cause the yield and total return of that Fund to be
higher than they would otherwise be in the absence of such fee reduction.
    
  The Distributor acts as agent for each of the Funds in the distribution of
their Shares and, in such capacity, solicits orders for the sale of Shares,
advertises, and pays the costs of advertising, office space and its personnel
involved in such activities. The Distributor receives no compensation under its
Distribution Agreement with the Group, but receives compensation under the
Distribution and Shareholder Service Plan described below and may retain all or
a portion of any sales charge imposed upon the purchase of Shares. See "HOW TO
PURCHASE AND REDEEM SHARES--Sales Charges."
 
EXPENSES
 
  The Adviser and the Administrator each bear all expenses in connection with
the performance of their services as investment adviser and administrator,
respectively, other than the cost of securities (including brokerage
commissions, if any) purchased for a Fund. Each Fund will bear the following
expenses relating to its operations: organizational expenses, taxes, interest,
any brokerage fees and commissions, fees and expenses of the Trustees of the
Group, Commission fees, state securities qualification fees, costs of preparing
and printing prospectuses for regulatory purposes and for distribution to the
Fund's current shareholders, outside auditing and legal expenses, advisory fees,
fund accounting fees, fees and out-of-pocket expenses of the custodian and
Transfer Agent, costs for independent pricing services, certain insurance
premiums, costs of maintenance of the Group's existence, costs of shareholders'
reports and meetings, distribution expenses incurred pursuant to the
Distribution and Shareholder Service Plan described below, administrative
services expenses incurred pursuant to the Administrative Services Plan
described below and any extraordinary expenses incurred in the Fund's operation.
 
                                       36
<PAGE>   37
 
DISTRIBUTION AND SHAREHOLDER SERVICE PLAN
 
  Pursuant to Rule 12b-1 under the 1940 Act, the Group has adopted a
Distribution and Shareholder Service Plan (the "Plan"), under which each Fund is
authorized to pay BISYS, as Distributor, a fee in an amount not to exceed on an
annual basis 0.25% of the average daily net asset value of that Fund (the "12b-1
Fee"). Payments of the 12b-1 Fee to BISYS pursuant to the Plan will be used (i)
to compensate Participating Organizations (as defined below) for providing
distribution assistance relating to Shares of a Fund, (ii) for promotional
activities intended to result in the sale of Shares of the Funds such as to pay
for the preparation, printing and distribution of prospectuses to other than
current shareholders, and (iii) to compensate Participating Organizations for
providing shareholder services with respect to their customers who are, from
time to time, beneficial and record holders of Shares of the Fund.
 
  Participating Organizations include banks, broker-dealers and other financial
institutions (including BISYS, FSC, the Adviser and their affiliates). Such fee
paid to BISYS may exceed the actual costs incurred by BISYS in providing such
services and/or compensating such Participating Organizations. In addition, from
time to time, BISYS may periodically voluntarily reduce all or a portion of its
fee under the Plan with respect to a Fund to increase the net income of that
Fund available for distribution as dividends. BISYS may not seek reimbursement
of such reduced fees after the end of the fiscal year in which the fees were
reduced. The voluntary reduction of such fee will cause the yield and total
return of that Fund to be higher than they would otherwise be in the absence of
such a fee reduction.
 
  BISYS may enter into, from time to time, other Rule 12b-1 Agreements with
selected dealers pursuant to which such dealers will provide certain services in
connection with the distribution of a Fund's Shares such as those described
above.
 
ADMINISTRATIVE SERVICES PLAN
 
  The Group has adopted an Administrative Services Plan (the "Services Plan")
pursuant to which each Fund is authorized to pay compensation to banks and other
financial institutions (each a "Service Organization"), which may include the
Adviser, its correspondent and affiliated banks, and BISYS, which agree to
provide certain ministerial, record keeping and/or administrative support
services for their customers or account holders (collectively, "customers") who
are the beneficial or record owner of Shares of that Fund. In consideration for
such services, a Service Organization receives a fee from a Fund, computed daily
and paid monthly, at an annual rate of up to .25% of the average daily net asset
value of Shares of that Fund owned beneficially or of record by such Service
Organization's customers for whom the Service Organization provides such
services.
 
  The servicing agreements adopted under the Services Plan (the "Servicing
Agreements") require the Service Organizations receiving such compensation to
perform certain ministerial, record keeping and/or administrative support
services with respect to the beneficial or record owners of Shares of the Funds,
such as processing dividend and distribution payments from the Fund on behalf of
customers, providing periodic statements to customers showing their positions in
the Shares of the Fund, providing sub-accounting with respect to Shares
beneficially owned by such customers and providing customers with a service that
invests the assets of their accounts in Shares of the Fund pursuant to specific
or pre-authorized instructions. As of the date hereof, no such servicing
agreements have been entered into by the Group.
 
BANKING LAWS
 
  The Adviser believes that it possesses the legal authority to perform the
investment advisory services for each Fund contemplated by its
 
                                       37
<PAGE>   38
 
investment advisory agreement with the Group, as described in this Prospectus,
without violation of applicable banking laws and regulations, and has so
represented in its investment advisory agreement with the Group. Future changes
in Federal or state statutes and regulations relating to permissible activities
of banks or bank holding companies and their subsidiaries and affiliates as well
as further judicial or administrative decisions or interpretations of present
and future statutes and regulations could change the manner in which the Adviser
could continue to perform such services for the Funds. See "MANAGEMENT OF THE
GROUP--Glass-Steagall Act" in the Statement of Additional Information for
further discussion of applicable law and regulations.
 
                              GENERAL INFORMATION
 
DESCRIPTION OF THE GROUP AND ITS SHARES
   
  The Group was organized as an Ohio business trust on April 25, 1988. The Group
consists of fourteen funds, each having its own class of shares. In addition to
the Funds, the Group consists of the following funds: Riverside Capital Money
Market Fund, Riverside Capital Value Equity Fund, Riverside Capital Fixed Income
Fund, Riverside Capital Low Duration Government Securities Fund, Riverside
Capital Growth Fund, Riverside Capital Tennessee Municipal Obligations Fund, The
KeyPremier Prime Money Market Fund and The KeyPremier Pennsylvania Municipal
Bond Fund. Each share represents an equal proportionate interest in a fund with
other shares of the same fund, and is entitled to such dividends and
distributions out of the income earned on the assets belonging to the fund as
are declared at the discretion of the Trustees (see "Miscellaneous" below).
 
  Shareholders are entitled to one vote for each dollar of value invested and a
proportionate fractional vote for any fraction of a dollar invested, and will
vote in the aggregate and not by series except as otherwise expressly required
by law. For example, Shareholders of each Fund will vote in the aggregate with
other shareholders of the Group with respect to the election of Trustees.
However, Shareholders of a Fund will vote as a fund, and not in the aggregate
with other shareholders of the Group, for purposes of approval of that Fund's
investment advisory agreement and the Plan.
 
  Overall responsibility for the management of the Funds is vested in the Board
of Trustees of the Group. See "MANAGEMENT OF THE GROUP--Trustees of the Group."
Individual Trustees are elected by the shareholders of the Group, although
Trustees may, under certain circumstances, fill vacancies, including vacancies
created by expanding the size of the Board. Trustees may be removed by the Board
of Trustees or shareholders in accordance with the provisions of the Declaration
of Trust and By-Laws of the Group and Ohio law. See "ADDITIONAL
INFORMATION--Miscellaneous" in the Statement of Additional Information for
further information.
    
   
  An annual or special meeting of shareholders to conduct necessary business is
not required by the Declaration of Trust, the 1940 Act or other authority
except, under certain circumstances, to elect Trustees, amend the Declaration of
Trust, the investment advisory agreement, the Plan or a Fund's fundamental
policies and to satisfy certain other requirements. To the extent that such a
meeting is not required, the Group does not intend to have an annual or special
meeting.
 
  The Group has represented to the Commission that the Trustees will call a
special meeting of shareholders for purposes of considering the removal of one
or more Trustees upon written request therefor from shareholders holding not
less than 10% of the outstanding votes of the Group. At such a meeting, a quorum
of shareholders (constituting a majority of votes attributable to all
outstanding shares of the
     
                                       38
<PAGE>   39
 
Group), by majority vote, has the power to remove one or more Trustees.
   
  As of the date immediately preceding the initial public offering of the Funds'
Shares, BISYS Fund Services Ohio, Inc. was the sole shareholder of each of the
Funds. It is expected that immediately after the public offering of the Funds'
Shares, BISYS Fund Services Ohio, Inc.'s holding of Shares of each Fund will be
reduced below 5%.
    
CUSTODIAN
 
  The Fifth Third Bank, 38 Fountain Square Plaza, Cincinnati, Ohio 45263, serves
as the custodian for each of the Funds.
 
TRANSFER AGENCY AND FUND ACCOUNTING SERVICES
   
  BISYS Fund Services, Inc., 3435 Stelzer Road, Columbus, Ohio 43219-3035,
serves as the Funds' transfer agent pursuant to a Transfer Agency Agreement with
the Group and receives a fee for such services. BISYS Fund Services, Inc. also
provides certain accounting services for each Fund pursuant to a Fund Accounting
Agreement and receives a fee for such services equal to the greater of (a) a fee
computed at an annual rate of 0.03% of the Fund's average daily net assets or
(b) $50,000 minus the fee paid by such Fund under its Management and
Administration Agreement with BISYS. See "Management of the Group--Transfer
Agency and Fund Accounting Services" in the Statement of Additional Information
for further information.
    
  While BISYS Fund Services, Inc. is a distinct legal entity from BISYS (the
Group's administrator and distributor), BISYS Fund Services, Inc. is considered
to be an affiliated person of BISYS under the 1940 Act due to, among other
things, the fact that BISYS Fund Services, Inc. is the general partner of BISYS.
 
MISCELLANEOUS
 
  Shareholders will receive unaudited semi-annual reports and annual reports
audited by independent accountants.
   
  As used in this Prospectus and in the Statement of Additional Information,
"assets belonging to the fund" means the consideration received by the fund upon
the issuance or sale of shares in that fund, together with all income, earnings,
profits, and proceeds derived from the investment thereof, including any
proceeds from the sale, exchange, or liquidation of such investments, and any
funds or amounts derived from any reinvestment of such proceeds, and any general
assets of the Group not readily identified as belonging to a particular fund
that are allocated to the fund by the Group's Board of Trustees. The Board of
Trustees may allocate such general assets in any manner it deems fair and
equitable. Determinations by the Board of Trustees of the Group as to the timing
of the allocation of general liabilities and expenses and as to the timing and
allocable portion of any general assets with respect to a Fund are conclusive.
    
  As used in this Prospectus and in the Statement of Additional Information, a
"vote of a majority of the outstanding Shares" of a Fund means the affirmative
vote, at a meeting of Shareholders duly called, of the lesser of (a) 67% or more
of the votes of Shareholders of that Fund present at a meeting at which the
holders of more than 50% of the votes attributable to Shareholders of record of
that Fund are represented in person or by proxy, or (b) the holders of more than
50% of the outstanding votes of Shareholders of that Fund.
 
  Inquiries regarding any of the Funds may be directed in writing to the Group
at 3435 Stelzer Road, Columbus, Ohio 43219, or by calling toll free (800)
766-8938.

                       STATEMENT OF ADDITIONAL INFORMATION

                               THE SESSIONS GROUP

         The Sessions Group (the "Group") is an open-end management investment
company which currently offers 14 separate investment portfolios. This Statement
of Additional Information deals with six of such portfolios, 1st Source Monogram
U.S. Treasury Obligations Money Market Fund (the "Money Market Fund"), 1st
Source Monogram Diversified Equity Fund (the "Diversified Equity Fund"), 1st
Source Monogram Income Equity Fund (the "Income Equity Fund"), 1st Source
Monogram Special Equity Fund (the "Special Equity Fund"), 1st Source Monogram
Income Fund (the "Income Fund") and 1st Source Monogram Intermediate Tax-Free
Bond Fund (the "Intermediate Tax-Free Fund"), each a diversified portfolio of
the Group (the Money Market Fund, the Diversified Equity Fund, the Income Equity
Fund, the Special Equity Fund, the Income Fund and the Intermediate Tax-Free
Fund are hereinafter collectively referred to as the "Funds" and individually as
a "Fund").

         Much of the information contained in this Statement of Additional
Information expands upon subjects discussed in the Prospectus. Capitalized terms
not defined herein are defined in the Prospectus. No investment in Shares of a
Fund should be made without first reading the Prospectus.

                       INVESTMENT OBJECTIVES AND POLICIES

ADDITIONAL INFORMATION ON PORTFOLIO INSTRUMENTS

         The following policies supplement the investment objectives and
policies of each Fund as set forth in the Prospectus.

         BANK OBLIGATIONS. Each of the Funds, other than the Money Market Fund,
may invest in bank obligations such as bankers' acceptances, certificates of
deposit, and demand and time deposits.

         Bankers' acceptances are negotiable drafts or bills of exchange
typically drawn by an importer or exporter to pay for specific merchandise,
which are "accepted" by a bank, meaning, in effect, that the bank
unconditionally agrees to pay the face value of the instrument on maturity.
Bankers' acceptances invested in by the Funds will be those guaranteed by
domestic and foreign banks having, at the time of investment, capital, surplus,
and undivided profits in excess of $100,000,000 (as of the date of their most
recently published financial statements).

         Certificates of deposit are negotiable certificates issued against
funds deposited in a commercial bank or a savings and loan association for a
definite period of time and earning a specified return. Certificates of deposit
and demand and time deposits will be those of domestic banks and savings and
loan associations, if (a) at the time of investment the depository institution
has


<PAGE>   44



capital, surplus, and undivided profits in excess of $100,000,000 (as of the
date of its most recently published financial statements), or (b) the principal
amount of the instrument is insured in full by the Federal Deposit Insurance
Corporation.

         COMMERCIAL PAPER. Commercial paper consists of unsecured promissory
notes issued by corporations. Issues of commercial paper normally have
maturities of less than nine months and fixed rates of return.

         The Funds, other than the Money Market Fund, will purchase commercial
paper consisting of issues rated at the time of purchase by one or more
appropriate nationally recognized statistical rating organizations ("NRSRO")
(e.g., Standard & Poor's Corporation and Moody's Investors Service, Inc.) in one
of the two highest rating categories for short-term debt obligations. The Funds
may also invest in commercial paper that is not rated but that is determined by
the Adviser or the applicable Sub-Adviser, as the case may be, to be of
comparable quality to instruments that are so rated by an NRSRO that is neither
controlling, controlled by, or under common control with the issuer of, or any
issuer, guarantor, or provider of credit support for, the instruments. For a
description of the rating symbols of the NRSROs, see the Appendix.

         VARIABLE AMOUNT MASTER DEMAND NOTES. Variable amount master demand
notes, in which the Income Fund may invest, are unsecured demand notes that
permit the indebtedness thereunder to vary and provide for periodic adjustments
in the interest rate according to the terms of the instrument. Because master
demand notes are direct lending arrangements between a Fund and the issuer, they
are not normally traded. Although there is no secondary market in the notes, a
Fund may demand payment of principal and accrued interest at any time within 30
days. While such notes are not typically rated by credit rating agencies,
issuers of variable amount master demand notes (which are normally
manufacturing, retail, financial and other business concerns), must satisfy, for
purchase by a Fund, the same criteria as set forth above for commercial paper
for such Fund. The Adviser will consider the earning power, cash flow, and other
liquidity ratios of the issuers of such notes and will continuously monitor
their financial status and ability to meet payment on demand. In determining
average weighted portfolio maturity, a variable amount master demand note will
be deemed to have a maturity equal to the longer of the period of time remaining
until the next interest rate adjustment or the period of time remaining until
the principal amount can be recovered from the issuer through demand.

         FOREIGN INVESTMENT. Investments in securities issued by foreign
issuers, including ADRs, may subject the Funds to investment risks that differ
in some respects from those related to investment in obligations of U.S.
domestic issuers or in U.S.

                                       B-2


<PAGE>   45



securities markets. Such risks include future adverse political and economic
developments, possible seizure, nationalization, or expropriation of foreign
investments, less stringent disclosure requirements, the possible establishment
of exchange controls or taxation at the source, or the adoption of other foreign
governmental restrictions. A Fund will acquire such securities only when the
Adviser or the applicable Sub-Adviser, as the case may be, believes the risks
associated with such investments are minimal.

         U.S. GOVERNMENT OBLIGATIONS. Each Fund may invest in obligations issued
or guaranteed by the U.S. Government or its agencies or instrumentalities.
Obligations of certain agencies and instrumentalities of the U.S. Government are
supported by the full faith and credit of the U.S. Treasury; others are
supported by the right of the issuer to borrow from the Treasury; others are
supported by the discretionary authority of the U.S. Government to purchase the
agency's obligations; and still others 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 agencies or
instrumentalities if it is not obligated to do so by law.

         EXEMPT SECURITIES. As stated in the Prospectus, the assets of the
Intermediate Tax-Free Fund will be primarily invested in Exempt Securities.
Under normal market conditions, at least 80% of the net assets of the
Intermediate Tax-Free Fund will be invested in Exempt Securities.

         Exempt Securities include debt obligations issued by governmental
entities to obtain funds for various public purposes, such as 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 other
public institutions and facilities.

         Among other types of Exempt Securities, the Intermediate TaxFree Fund
may purchase short-term General Obligation Notes, Tax Anticipation Notes, Bond
Anticipation Notes, Revenue Anticipation Notes, Project Notes, Tax-Exempt
Commercial Paper, Construction Loan Notes 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. In addition, the Intermediate Tax-Free Fund may invest in other
types of tax-exempt instruments, such as municipal bonds and pollution control
bonds.

         Project Notes are issued by a state or local housing agency and are
sold by the Department of Housing and Urban Development. While the issuing
agency has the primary obligation with respect to its Project Notes, they are
also secured by the full faith and

                                       B-3


<PAGE>   46



credit of the United States through agreements with the issuing authority which
provide that, if required, the federal government will lend the issuer an amount
equal to the principal of and interest on the Project Notes.

         As described in the Prospectus, the two principal classifications of
Exempt Securities consist of "general obligation" and "revenue" issues. The
Intermediate Tax-Free Fund may also acquire "moral obligation" issues, which are
normally issued by special purpose authorities. There are, of course, variations
in the quality of Exempt Securities, both within a particular classification and
between classifications, and the yields on Exempt Securities depend upon a
variety of factors, including 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. Ratings represent the
opinions of an NRSRO as to the quality of Exempt Securities. It should be
emphasized, however, that ratings are general and are not absolute standards of
quality, and Exempt Securities with the same maturity, interest rate and rating
may have different yields, while Exempt Securities of the same maturity and
interest rate with different ratings may have the same yield. Subsequent to
purchase, an issue of Exempt Securities may cease to be rated or its rating may
be reduced below the minimum rating required for purchase. The Adviser will
consider such an event in determining whether the Intermediate Tax-Free Fund
should continue to hold the obligation.

         An issuer's obligations under its Exempt 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 Congress or state legislatures extending the time for
payment of principal or interest, or both, or imposing other constraints upon
the enforcement of such obligations or upon the ability of municipalities to
levy taxes. The power or ability of an issuer to meet its obligations for the
payment of interest on and principal of its Exempt Securities may be materially
adversely affected by litigation or other conditions.

         VARIABLE AND FLOATING RATE NOTES. The Income and the Intermediate
Tax-Free Funds may each acquire variable and floating rate notes, subject to
such Fund's investment objectives, policies and restrictions. A variable rate
note is one whose terms provide for the adjustment of its interest rate on set
dates and which, upon such adjustment, can reasonably be expected to have a
market value that approximates its par value. A floating rate note is one whose
terms provide for the adjustment of its interest rate whenever a specified
interest rate changes and which, at any time, can reasonably be expected to have
a market value that approximates its par value. Such notes are frequently not
rated by credit

                                       B-4


<PAGE>   47



rating agencies; however, unrated variable and floating rate notes purchased by
such Funds will be determined by the Adviser or the applicable Sub-Adviser, as
the case may be, to be of comparable quality at the time of purchase to rated
instruments eligible for purchase under that particular Fund's investment
policies. In making such determinations, the Adviser or Sub-Adviser, as the case
may be, will consider the earning power, cash flow and other liquidity ratios of
the issuers of such notes (such issuers include financial, merchandising, bank
holding and other companies) and will continuously monitor their financial
condition. Although there may be no active secondary market with respect to a
particular variable or floating rate note purchased by a Fund, the Fund may
resell the note at any time to a third party. The absence of an active secondary
market, however, could make it difficult for a Fund to dispose of a variable or
floating rate note in the event the issuer of the note defaulted on its payment
obligations and the Fund could, as a result or for other reasons, suffer a loss
to the extent of the default. To the extent that there exists no readily
available market for such note and a Fund is not entitled to receive the
principal amount of a note within seven days, such a note will be treated as an
illiquid security for purposes of calculation of such Fund's limitation on
investments in illiquid securities, as set forth in the respective Fund's
investment restrictions. Variable or floating rate notes may be secured by bank
letters of credit.

         RESTRICTED SECURITIES. Securities in which the Diversified Equity,
Income Equity, Special Equity and Income Funds may invest include securities
issued by corporations without registration under the Securities Act of 1933, as
amended (the "1933 Act"), in reliance on the exemption from such registration
afforded by Section 3(a)(3) thereof, and securities issued in reliance on the
so-called "private placement" exemption from registration which is afforded by
Section 4(2) of the 1933 Act ("Section 4(2) securities"). Section 4(2)
securities are restricted as to disposition under the Federal securities laws,
and generally are sold to institutional investors such as the Funds who agree
that they are purchasing the securities for investment and not with a view to
public distribution. Any resale must also generally be made in an exempt
transaction. Section 4(2) securities are normally resold to other institutional
investors through or with the assistance of the issuer or investment dealers who
make a market in such Section 4(2) securities, thus providing liquidity. Any
such restricted securities will be considered to be illiquid for purposes of a
Fund's limitations on investments in illiquid securities unless, pursuant to
procedures adopted by the Board of Trustees of the Group, the Adviser has
determined such securities to be liquid because such securities are eligible for
resale under Rule 144A under the 1933 Act and are readily saleable. Each such
Funds will each limit its investment in Section 4(2) securities to not more than
10% of its net assets.

                                       B-5


<PAGE>   48




         OPTIONS TRADING. Each of the Diversified Equity Fund, the Income Equity
Fund, the Special Equity Fund and the Income Fund may purchase put and call
options. A put option gives the purchaser the right to sell 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. A call option
gives the purchaser of the option the right to buy, and a writer has the
obligation to sell, 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 consideration for undertaking
the obligations under the option contract. Put and call options purchased by
such Funds will be valued at the last sale price, or in the absence of such a
price, at the mean between bid and asked price.

         When a Fund writes a call 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 the deferred credit will be subsequently
marked-to-market to reflect the current value of the option written. The current
value of the traded option is the last sale price or, in the absence of a sale,
the mean between bid and asked price. If an option expires on the stipulated
expiration date or if the Fund enters into a closing purchase transaction, it
will realize a gain (or a 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 is exercised, the
Fund may deliver the underlying security in the open market. In either event,
the proceeds of the sale will be increased by the net premium originally
received and the Fund will realize a gain or loss.

         Each such Fund may also purchase or sell index options. Index options
(or options on securities indices) are similar in many respects to options on
securities except that an index option gives the holder the right to receive,
upon exercise, cash instead of securities, if the closing level of the
securities index upon which the option is based is greater than, in the case of
a call, or less than, in the case of a put, the exercise price of the option.

         PUTS. The Intermediate Tax-Free Fund may also acquire "puts" with
respect to Exempt Securities held in its portfolio. A put is a right to sell a
specified security (or securities) within a specified period of time at a
specified exercise price. The Intermediate Tax-Free Fund may sell, transfer, or
assign a put only in conjunction with the sale, transfer, or assignment of the
underlying security or securities.

                                       B-6


<PAGE>   49



         The amount payable to the Intermediate Tax-Free Fund upon its exercise
of a "put" is normally (i) the Intermediate Tax-Free Fund's acquisition cost of
the Exempt Securities (excluding any accrued interest which the Intermediate
Tax-Free Fund paid on the acquisition), less any amortized market premium or
plus any amortized market or original issue discount during the period the
Intermediate Tax-Free Fund owned the securities, plus (ii) all interest accrued
on the securities since the last interest payment date during that period.

         Puts may be acquired by the Intermediate Tax-Free Fund to facilitate
the liquidity of its portfolio assets. Puts may also be used to facilitate the
reinvestment of the Intermediate Tax-Free Fund's assets at a rate of return more
favorable than that of the underlying security. Puts may, under certain
circumstances, also be used to shorten the maturity of underlying variable rate
or floating rate securities for purposes of calculating the remaining maturity
of those securities.

         The Intermediate Tax-Free Fund expects that it will generally acquire
puts only where the puts are available without the payment of any direct or
indirect consideration. However, if necessary or advisable, the Intermediate
Tax-Free Fund may pay for puts either separately in cash or by paying a higher
price for portfolio securities which are acquired subject to the puts (thus
reducing the yield to maturity otherwise available for the same securities).

         The Intermediate Tax-Free Fund intends to enter into puts only with
dealers, banks, and broker-dealers which, in the Adviser's opinion, present
minimal credit risks.

         FUTURE CONTRACTS. As discussed in the Prospectus, each of the Funds,
other than the Money Market Fund, may enter into futures contracts. This
investment technique is designed primarily to hedge against anticipated future
changes in market conditions which otherwise might adversely affect the value of
securities which a Fund holds or intends to purchase. For example, when interest
rates are expected to rise or market values of portfolio securities are expected
to fall, a Fund can seek through the sale of futures contracts to offset a
decline in the value of its portfolio securities. When interest rates are
expected to fall or market values are expected to rise, a Fund, through the
purchase of such contracts, can attempt to secure better rates or prices for the
Fund than might later be available in the market when it effects anticipated
purchases.

         The acquisition of put and call options on futures contracts will,
respectively, give a Fund the right (but not the obligation), for a specified
price, to sell or to purchase the underlying futures contract, upon exercise of
the option, at any time during the option period.

                                       B-7


<PAGE>   50




         Futures transactions involve brokerage costs and require a Fund to
segregate liquid assets, such as cash, U.S. Government securities or other
liquid high grade debt obligations, to cover its performance under such
contracts. A Fund may lose the expected benefit of futures transactions if
interest rates, securities prices or foreign exchange rates move in an
unanticipated manner. Such unanticipated changes may also result in poorer
overall performance than if the Fund had not entered into any futures
transactions. In addition, the value of a Fund's futures positions may not prove
to be perfectly or even highly correlated with the value of its portfolio
securities, limiting the Fund's ability to hedge effectively against interest
rate and/or market risk and giving rise to additional risks. There is no
assurance of liquidity in the secondary market for purposes of closing out
futures positions.

         REGULATORY RESTRICTIONS. To the extent required to comply with
Securities and Exchange Commission Release No. IC-10666, when purchasing a
futures contract or writing a put option, a Fund will maintain in a segregated
account cash or liquid high-grade securities equal to the value of such
contracts.

         To the extent required to comply with Commodity Futures Trading
Commission Regulation 4.5 and thereby avoid being classified as a "commodity
pool operator," a Fund will not enter into a futures contract or purchase an
option thereon if immediately thereafter the initial margin deposits for futures
contracts held by such Fund plus premiums paid by it for open options on futures
would exceed 5% of such Fund's total assets. A Fund will not engage in
transactions in financial futures contracts or options thereon for speculation,
but only to attempt to hedge against changes in market conditions affecting the
values of securities which such Fund holds or intends to purchase. When futures
contracts or options thereon are purchased to protect against a price increase
on securities intended to be purchased later, it is anticipated that at least
25% of such intended purchases will be completed. When other futures contracts
or options thereon are purchased, the underlying value of such contracts will at
all times not exceed the sum of: (1) accrued profit on such contracts held by
the broker; (2) cash or high quality money market instruments set aside in an
identifiable manner, and (3) cash proceeds from investments due in 30 days.

         WHEN-ISSUED SECURITIES. As discussed in the Prospectus, the Income Fund
and the Intermediate Tax-Free Fund may each purchase securities on a
"when-issued" basis (i.e., for delivery beyond the normal settlement date at a
stated price and yield). When such Fund agrees to purchase securities on a
"when-issued" basis, the Fund's custodian will set aside cash or liquid
portfolio securities equal to the amount of the commitment in a separate
account. Normally, the Fund's custodian will set aside portfolio securities

                                       B-8


<PAGE>   51



to satisfy the purchase commitment, and in such a case, such Fund may be
required subsequently to place additional assets in the separate account in
order to assure that the value of the account remains equal to the amount of the
Fund's commitment. It may be expected that a Fund's net assets will fluctuate to
a greater degree when it sets aside portfolio securities to cover such purchase
commitments than when it sets aside cash. In addition, because a Fund will set
aside cash or liquid portfolio securities to satisfy its purchase commitments in
the manner described above, such Fund's liquidity and the ability of the Adviser
to manage it might be affected in the event its commitments to purchase
"when-issued" securities ever exceeded 25% of the value of its total assets.
Under normal market conditions, however, neither the Income Fund's nor the
Intermediate Tax-Free Fund's commitment to purchase "when-issued" or
"delayed-delivery" securities will exceed 25% of the value of its total assets.

         When a Fund engages in "when-issued" transactions, it relies on the
seller to consummate the trade. Failure of the seller to do so may result in
such Fund's incurring a loss or missing the opportunity to obtain a price
considered to be advantageous. The Income Fund and the Intermediate Tax-Free
Fund will each engage in "when-issued" delivery transactions only for the
purpose of acquiring portfolio securities consistent with that Fund's investment
objectives and policies and not for investment leverage.

         MORTGAGE-RELATED SECURITIES. The Income Fund may, consistent with its
investment objective and policies, invest in mortgage-related securities issued
or guaranteed by the U.S. Government or its agencies or instrumentalities.

         Mortgage-related securities, for purposes of the Prospectus and this
Statement of Additional Information, represent pools of mortgage loans assembled
for sale to investors by various governmental agencies such as the Government
National Mortgage Association and government-related organizations such as the
Federal National Mortgage Association and the Federal Home Loan Mortgage
Corporation, as well as by nongovernmental issuers such as commercial banks,
savings and loan institutions, mortgage bankers and private mortgage insurance
companies. Although certain mortgage-related securities are guaranteed by a
third party or otherwise similarly secured, the market value of the security,
which may fluctuate, is not so secured. If the Income Fund purchases a
mortgage-related security at a premium, that portion may be lost if there is a
decline in the market value of the security whether resulting from changes in
interest rates or prepayments in the underlying mortgage collateral. As with
other interest-bearing securities, the prices of such securities are inversely
affected by changes in interest rates. However, though the value of a
mortgage-related security may decline when interest rates rise, the converse is
not necessarily true, since in periods

                                       B-9


<PAGE>   52



of declining interest rates the mortgages underlying the securities are prone to
prepayment, thereby shortening the average life of the security and shortening
the period of time over which income at the higher rate is received. Conversely,
when interest rates are rising, the rate of prepayment tends to decrease,
thereby lengthening the average life of the security and lengthening the period
of time over which income at the lower rate is received. For these and other
reasons, a mortgage-related security's average maturity may be shortened or
lengthened as a result of interest rate fluctuations and, therefore, it is not
possible to predict accurately the security's return to the Income Fund. In
addition, regular payments received in respect of mortgage-related securities
include both interest and principal. No assurance can be given as to the return
the Income Fund will receive when these amounts are reinvested.

         The Income Fund may invest in mortgage-related securities which are
collateralized mortgage obligations structured on pools of mortgage pass-through
certificates or mortgage loans. Mortgage-related securities will be purchased
only if rated in the three highest bond rating categories assigned by one or
more appropriate NRSROs, or, if unrated, which the Adviser deems to be of
comparable quality.

         There are a number of important differences among the agencies and
instrumentalities of the U.S. Government that issue mortgage-related securities
and among the securities that they issue. Mortgage-related securities issued by
the Government National Mortgage Association ("GNMA") include GNMA Mortgage
Pass-Through Certificates (also known as "Ginnie Maes") which are guaranteed as
to the timely payment of principal and interest by GNMA and such guarantee is
backed by the full faith and credit of the United States. GNMA is a wholly-owned
U.S. Government corporation within the Department of Housing and Urban
Development. GNMA certificates also are supported by the authority of GNMA to
borrow funds from the U.S. Treasury to make payments under its guarantee.
Mortgage-related securities issued by the Federal National Mortgage Association
("FNMA") include FNMA Guaranteed Mortgage Pass-Through Certificates (also known
as "Fannie Maes") which are solely the obligations of the FNMA and are not
backed by or entitled to the full faith and credit of the United States. The
FNMA is a government-sponsored organization owned entirely by private
stockholders. Fannie Maes are guaranteed as to timely payment of the principal
and interest by FNMA. Mortgage-related securities issued by the Federal Home
Loan Mortgage Corporation ("FHLMC") include FHLMC Mortgage Participation
Certificates (also known as "Freddie Macs" or "PCs"). The FHLMC is a corporate
instrumentality of the United States, created pursuant to an Act of Congress,
which is owned entirely by Federal Home Loan Banks. Freddie Macs are not
guaranteed by the United States or by any Federal Home Loan Banks and do not
constitute a debt or obligation of the United States or

                                      B-10


<PAGE>   53



of any Federal Home Loan Bank. Freddie Macs entitle the holder to timely payment
of interest, which is guaranteed by the FHLMC. The FHLMC guarantees either
ultimate collection or timely payment of all principal payments on the
underlying mortgage loans. When the FHLMC does not guarantee timely payment of
principal, FHLMC may remit the amount due on account of its guarantee of
ultimate payment of principal at any time after default on an underlying
mortgage, but in no event later than one year after it becomes payable.

         REPURCHASE AGREEMENTS. Securities held by each of the Funds may be
subject to repurchase agreements. Under the terms of a repurchase agreement, a
Fund would acquire securities from member banks of the Federal Deposit Insurance
Corporation and registered broker-dealers which the Adviser or the applicable
Sub-Adviser, as the case may be, deems creditworthy under guidelines approved by
the Group's Board of Trustees, subject to the seller's agreement to repurchase
such securities at a mutually agreed-upon date and price. The repurchase price
would generally equal the price paid by the Fund plus interest negotiated on the
basis of current short-term rates, which may be more or less than the rate on
the underlying portfolio securities. The seller under a repurchase agreement
will be required to maintain continually the value of collateral held pursuant
to the agreement at not less than the repurchase price (including accrued
interest). This requirement will be continually monitored by the Adviser. If the
seller were to default on its repurchase obligation or become insolvent, the
Fund holding such obligation would suffer a loss to the extent that the proceeds
from a sale of the underlying portfolio securities were less than the repurchase
price under the agreement, or to the extent that the disposition of such
securities by the Fund were delayed pending court action. Additionally, there is
no controlling legal precedent confirming that a Fund would be entitled, as
against a claim by such seller or its receiver or trustee in bankruptcy, to
retain the underlying securities, although the Board of Trustees of the Group
believes that, under the regular procedures normally in effect for custody of a
Fund's securities subject to repurchase agreements and under federal laws, a
court of competent jurisdiction would rule in favor of the Group if presented
with the question. Securities subject to repurchase agreements will be held by
that Fund's custodian or another qualified custodian or in the Federal
Reserve/Treasury book-entry system. Repurchase agreements are considered to be
loans by a Fund under the 1940 Act.

         REVERSE REPURCHASE AGREEMENTS. As discussed in the Prospectus, each of
the Funds may borrow funds by entering into reverse repurchase agreements in
accordance with that Fund's investment restrictions. Pursuant to such
agreements, a Fund would sell portfolio securities to financial institutions
such as banks and broker-dealers, and agree to repurchase the securities at a

                                      B-11


<PAGE>   54



mutually agreed-upon date and price. Each Fund intends to enter into reverse
repurchase agreements only to avoid otherwise selling securities during
unfavorable market conditions to meet redemptions. At the time a Fund enters
into a reverse repurchase agreement, it will place in a segregated custodial
account assets such as U.S. Government securities or other liquid, high grade
debt securities consistent with the Fund's investment restrictions having a
value equal to the repurchase price (including accrued interest), and will
subsequently continually monitor the account to ensure that such equivalent
value is maintained at all times. Reverse repurchase agreements involve the risk
that the market value of the securities sold by a Fund may decline below the
price at which a Fund is obligated to repurchase the securities. Reverse
repurchase agreements are considered to be borrowings by a Fund under the 1940
Act.
   

         SECURITIES OF OTHER INVESTMENT COMPANIES. Each Fund may invest in
securities issued by other investment companies. Each Fund currently intends to
limit its investments so that, as determined immediately after a securities
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; and (c) not more than 3% of the outstanding
voting stock of any one investment company will be owned by such Fund. As a
shareholder of another investment company, a Fund would bear, along with other
shareholders, its pro rata portion of that company's expenses, including
advisory fees. These expenses would be in addition to the advisory and other
expenses that such Fund bears directly in connection with its own operations.
Investment companies in which the Funds may investment may also impose a sales
or distribution charge in connection with the purchase or redemption of their
shares and other types of commissions or charges. Such charges will be payable
by such Fund and, therefore, will be borne directly by shareholders.
    

Investment Restrictions
- -----------------------

         Each Fund's investment objective is a non-fundamental policy and may be
changed without a vote of the holders of a majority of such Fund's outstanding
Shares. In addition to the fundamental investment policies listed in the
Prospectus, the following investment restrictions may be changed with respect to
a particular Fund only by a vote of the majority of the outstanding Shares of
that Fund (as defined under "ADDITIONAL INFORMATION - Vote of a Majority of the
Outstanding Shares").

         In addition to the investment restrictions set forth in the Prospectus,
each of the Funds may not:

                                      B-12


<PAGE>   55



         1. Purchase securities on margin, except for use of short-term credit
necessary for clearance of purchases of portfolio securities and except as may
be necessary to make margin payments in connection with derivative securities
transactions;

         2. Underwrite the securities issued by other persons, except to the
extent that the Fund may be deemed to be an underwriter under certain securities
laws in the disposition of "restricted securities;"

         3. Purchase or sell real estate (although investments in marketable
securities of companies engaged in such activities and securities secured by
real estate or interests therein are not prohibited by this restriction); and

         4. Purchase or sell commodities or commodities contracts, except to the
extent disclosed in the current Prospectus of the Fund.

         The following additional investment restrictions may be changed without
the vote of a majority of the outstanding Shares of a Fund. Each Fund may not:

         1. Purchase securities of other investment companies, except (a) in
connection with a merger, consolidation, acquisition or reorganization, and (b)
to the extent permitted by the 1940 Act, or pursuant to any exemptions
therefrom;

         2. Engage in any short sales;

         3. Purchase or retain the securities of an issuer if the officers or
trustees of the Group, or the officers or directors of the Adviser, who each
owns beneficially more than .5% of the outstanding securities of such issuer,
together own beneficially more than 5% of such securities; and

         4.       Mortgage or hypothecate the Fund's assets in excess of
one-third of the Fund's total assets.

         If any percentage restriction or requirement described above is
satisfied at the time of investment, a later increase or decrease in such
percentage resulting from a change in asset value will not constitute a
violation of such restriction or requirement. However, should a change in net
asset value or other external events cause a Fund's investments in illiquid
securities, repurchase agreements with maturities in excess of seven days and
other instruments in such Fund which are not readily marketable to exceed the
limit set forth in such Fund's Prospectus for its investment in illiquid
securities, the Fund will act to cause the aggregate amount of such securities
to come within such limit as soon as reasonably practicable. In such an event,
however, such

                                      B-13


<PAGE>   56



Fund would not be required to liquidate any portfolio securities where the Fund
would suffer a loss on the sale of such securities.

   
         The Group, on behalf of each Fund, has represented to the Ohio Division
of Securities that each Fund will not invest any of its assets in the securities
of other investment companies, except by purchase in the open market where no
commission or profit to a sponsor or dealer results from the purchase other than
the customary broker's commission, or except when the purchase is part of a plan
of merger, consolidation, reorganization, or acquisition. The Group intends to
comply with this representation with respect to each Fund for so long as such
representation is required by the Ohio Division of Securities.
    

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

         The portfolio turnover rate for each of the Funds is calculated by
dividing the lesser of a Fund's purchases or sales of portfolio securities for
the year by the monthly average value of the portfolio securities. The
calculation excludes all securities whose remaining maturities at the time of
acquisition were one year or less.

         Because the Money Market Fund intends to invest entirely in securities
with maturities of less than one year and because the Commission requires such
securities to be excluded from the calculation of portfolio turnover rate, the
portfolio turnover with respect to the Money Market Fund is expected to be zero
percent for regulatory purposes. The portfolio turnover rates for each of the
Diversified Equity Fund, the Income Equity Fund, the Special Equity Fund, the
Income Fund and the Intermediate Tax-Free Fund for the current fiscal year are
estimated to be less than 100%, 70%, 150%, 80% and 30%, respectively. The
portfolio turnover rate may vary greatly from year to year as well as within a
particular year, and may also be affected by cash requirements for redemptions
of Shares. High portfolio turnover rates will generally result in higher
transaction costs, including brokerage commissions, to a Fund and may result in
additional tax consequences to a Fund's Shareholders. Portfolio turnover will
not be a limiting factor in making investment decisions.

                                 NET ASSET VALUE

         As indicated in the Prospectus, the net asset value of each Fund is
determined and the Shares of each Fund are priced as of the Valuation Time or
Times (in the case of the Money Market Fund) on each Business Day of that Fund.
A "Business Day" of a Fund is a day on which the New York Stock Exchange is open
for trading and any other day (other than a day on which no Shares of that Fund
are tendered for redemption and no order to purchase any Shares of that Fund is
received) during which there is sufficient trading in

                                      B-14


<PAGE>   57



portfolio instruments that such Fund's net asset value per share might be
materially affected. The New York Stock Exchange will not open in observance of
the following holidays: New Year's Day, President's Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving, and Christmas.

Valuation of the Money Market Fund
- ----------------------------------

         The Money Market Fund has elected to use the amortized cost method of
valuation pursuant to Rule 2a-7 under the 1940 Act. This involves valuing an
instrument at its cost initially and thereafter assuming a constant amortization
to maturity of any discount or premium, regardless of the impact of fluctuating
interest rates on the market value of the instrument. This method may result in
periods during which value, as determined by amortized cost, is higher or lower
than the price the Money Market Fund would receive if it sold the instrument.
The value of securities in the Money Market Fund can be expected to vary
inversely with changes in prevailing interest rates.

         Pursuant to Rule 2a-7, the Money Market Fund will maintain a
dollar-weighted average portfolio maturity appropriate to the Money Market
Fund's objective of maintaining a stable net asset value per share, provided
that the Money Market Fund will not purchase any security with a remaining
maturity of more than 397 days (thirteen months) (securities subject to
repurchase agreements may bear longer maturities) nor maintain a dollar-weighted
average portfolio maturity which exceeds 90 days. The Group's Board of Trustees
has also undertaken to establish procedures reasonably designed, taking into
account current market conditions and the investment objective of the Money
Market Fund, to stabilize the net asset value per share of the Money Market Fund
for purposes of sales and redemptions at $1.00. These procedures include review
by the Trustees, at such intervals as they deem appropriate, to determine the
extent, if any, to which the net asset value per share of the Money Market Fund
calculated by using available market quotations deviates from $1.00 per Share.
In the event such deviation exceeds one-half of one percent, Rule 2a-7 requires
that the Board of Trustees promptly consider what action, if any, should be
initiated. If the Trustees believe that the extent of any deviation from the
Money Market Fund's $1.00 amortized cost price per Share may result in material
dilution or other unfair results to new or existing investors, they will take
such steps as they consider appropriate to eliminate or reduce, to the extent
reasonably practicable, any such dilution or unfair results. These steps may
include selling portfolio instruments prior to maturity, shortening the average
portfolio maturity, withholding or reducing dividends, reducing the number of
the Money Market Fund's outstanding Shares without monetary consideration, or
utilizing a net asset value per share determined by using available market
quotations.

                                      B-15


<PAGE>   58




Valuation of the Other Funds
- ----------------------------

         Investments in securities for which market quotations are readily
available are valued based upon their current available prices in the principal
market in which such securities are normally traded. Unlisted securities for
which market quotations are readily available are valued at such market value.
Securities and other assets for which quotations are not readily available are
valued at their fair value as determined in good faith under consistently
applied procedures established by and under the general supervision of the
Trustees of the Group. Short-term securities (i.e., with maturities of 60 days
or less) are valued at either amortized cost or original cost plus accrued
interest, which approximates current value.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

         Shares of each of the Funds are sold on a continuous basis by BISYS,
and BISYS has agreed to use appropriate efforts to solicit all purchase orders.
In addition to purchasing Shares directly from BISYS, Shares may be purchased
through procedures established by BISYS in connection with the requirements of
accounts at the Adviser or the Adviser's affiliated entities (collectively,
"Entities"). Customers purchasing Shares of the Funds may include officers,
directors, or employees of the Adviser or the Entities.

         The Group 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 (the "Exchange") is restricted by applicable rules and regulations of
the Commission, (b) the Exchange is closed for other than customary weekend and
holiday closings, (c) the Commission has by order permitted such suspension, or
(d) an emergency exists as a result of which (i) disposal by the Group of
securities owned by it is not reasonably practical, or (ii) it is not reasonably
practical for the Group to determine the fair value of its net assets.

                             MANAGEMENT OF THE GROUP

Trustees and Officers
- ---------------------

         Overall responsibility for management of the Group rests with its Board
of Trustees, which is elected by the shareholders of the Group's funds. The
Trustees elect the officers of the Group to supervise actively its day-to-day
operations.

         The names of the Trustees and officers of the Group, their addresses,

Investment Adviser
- ------------------
   

         Investment advisory and management services are provided to the Funds
of the Group by 1st Source Bank (the "Adviser"), pursuant to an Investment
Advisory Agreement dated as of August 20, 1996. Under the terms of the
Investment Advisory Agreement, the Adviser has agreed to provide, either
directly or through one or more subadvisers, investment advisory services as
described in the Prospectus of the Funds. For the services provided and expenses
assumed pursuant to the Investment Advisory Agreement, each Fund
    

                                      B-19


<PAGE>   62



pays the Adviser a fee, computed daily and paid monthly, at the following annual
rates: (1) for the Money Market Fund, thirty-five one-hundredths of one percent
(0.35%) of such Fund's average daily net assets; (2) for the Diversified Equity
Fund, one hundred ten one-hundredths of one percent (1.10%) of such Fund's
average daily net assets; (3) for the Income Equity Fund, eighty one-hundredths
of one percent (0.80%) of such Fund's average daily net assets; (4) for the
Special Equity Fund, eighty one-hundredths of one percent (0.80%) of such Fund's
average daily net assets; (5) for the Income Fund, fifty-five one-hundredths of
one percent (0.55%) of such Fund's average daily net assets; and (6) for the
Intermediate Tax-Free Fund, fifty-five one-hundredths of one percent (0.55%) of
such Fund's average daily net assets. The Adviser may from time to time
voluntarily reduce all or a portion of its advisory fee with respect to a Fund
to increase the net income of that Fund available for distribution as dividends.
   

         Unless sooner terminated, the Investment Advisory Agreement will
continue in effect until August 20, 1998, and year to year thereafter for
successive annual periods ending on August 20, if, as to each Fund, such
continuance is approved at least annually by the Group's Board of Trustees or by
vote of a majority of the outstanding Shares of the relevant Fund (as defined
under "GENERAL INFORMATION - Miscellaneous" in the Funds' Prospectus), and a
majority of the Trustees who are not parties to the Investment Advisory
Agreement or interested persons (as defined in the 1940 Act) of any party to the
Investment Advisory Agreement by votes cast in person at a meeting called for
such purpose. The Investment Advisory Agreement is terminable as to a Fund at
any time on 60 days' written notice without penalty by the Trustees, by vote of
a majority of the outstanding Shares of that Fund, or by the Adviser. The
Investment Advisory Agreement also terminates automatically in the event of any
assignment, as defined in the 1940 Act.
    

         The Investment Advisory Agreement provides that the Adviser shall not
be liable for any error of judgment or mistake of law or for any loss suffered
by a Fund in connection with the performance of the Investment Advisory
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 Adviser in the
performance of its duties, or from reckless disregard by the Adviser of its
duties and obligations thereunder.

         The Adviser has licensed the name "1st Source Monogram" to the Funds on
a royalty-free basis, and the Adviser has reserved to itself the right to grant
the non-exclusive right to use the name "1st Source Monogram" to any other
person. At such time as the Investment Advisory Agreement is no longer in
effect, the Adviser

                                      B-20


<PAGE>   63



may require the Funds to cease using the name "1st Source Monogram."

SUBADVISERS
   

         Pursuant to the terms of the Investment Advisory Agreement, the Adviser
has entered into three separate Sub-Investment Advisory Agreements each dated as
of August 20, 1996 (collectively, the "Sub-Advisory Agreements"). The first
Sub-Advisory Agreement is with Miller Anderson & Sherrerd LLP, One Tower Bridge,
Suite 1100, West Conshohocken, Pennsylvania 19428 ("Miller Anderson"). The
second Sub-Advisory Agreement is with Loomis, Sayles & Company, L.P., 3 First
National Plaza, Suite 5450, Chicago, Illinois 60600 ("Loomis"). The third
Sub-Advisory Agreement is with Columbus Circle Investors, One Station Place,
Stamford, Connecticut 06902 ("Columbus"). Pursuant to the terms of such
Sub-Investment Advisory Agreements, each of Miller Anderson, Loomis and Columbus
has been retained by the Adviser to manage the investment and reinvestment of a
portion the assets of the Diversified Equity Fund, subject to the direction and
control of the Adviser and the Group's Board of Trustees.
    

         Under this arrangement, the Sub-Advisers are responsible for the
day-to-day management of the Diversified Equity Fund's assets, investment
performance, policies and guidelines, and maintaining certain books and records,
and the Adviser is responsible for selecting and monitoring the performance of
each of the SubAdvisers, and for reporting the activities of the Sub-Advisers in
managing the Diversified Equity Fund to the Group's Board of Trustees.

         For their services provided and expenses assumed pursuant to their
respective Sub-Investment Advisory Agreement with the Adviser, the Sub-Advisers
receive from the Adviser a fee (computed daily and paid monthly as a percentage
of the Diversified Equity Fund's average daily net assets managed by that
Sub-Adviser) at the following annual rates: for Miller Anderson, 0.625% up to
$25,000,000 and 0.375% of the excess over $25,000,000; for Loomis, 0.65% up to
$5,000,000 and 0.50% of the excess over $5,000,000; and for Columbus, 1.00% up
to $10,000,000 and 0.50% of the excess over $10,000,000.

         Miller Anderson was founded in 1969 and became wholly owned by The
Morgan Stanley Group, Inc. in December, 1995.

         Loomis was founded in 1926 and established its Chicago office in 1952.
Loomis' sole general partner is Loomis, Sayles & Company, Incorporated.

                                      B-21


<PAGE>   64



         Columbus was founded in 1975 and is a sub-partnership of PIMCO Advisors
L.P., a publicly held limited partnership whose general partner is owned by
Pacific Mutual Life Insurance Company and the managing directors of one of the
subpartnerships of PIMCO Advisors L.P.
   

         Unless sooner terminated, each of the Sub-Investment Advisory
Agreements continue in effect as to the Diversified Equity Fund until August 20,
1998, and thereafter for successive one-year periods ending August 20 of each
year if such continuance is approved at least annually by the Group's Board of
Trustees or by vote of a majority of the outstanding shares of such Fund (as
defined under "GENERAL INFORMATION - Miscellaneous" in the Funds' Prospectus),
and a majority of the Trustees who are not parties to the Sub-Investment
Advisory Agreements or interested persons (as defined in the 1940 Act) of any
party to the Sub-Investment Advisory Agreements by votes cast in person at a
meeting called for such purpose. Each of the Sub-Investment Advisory Agreements
are terminable as to the Diversified Equity Fund at any time on 60 days' written
notice without penalty by the Fund, by vote of a majority of the outstanding
shares of that Fund, or on 60 days' prior written notice from the Subadviser.
Such Agreements also terminate automatically in the event of any assignment, as
defined in the 1940 Act.
    

         Each of the Sub-Investment Advisory Agreements provide that the
respective Sub-Advisers shall not be liable for any error of judgment or mistake
of law or for any loss suffered by the Group in connection with the performance
of their duties, 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
respective Sub-Advisers in the performance of their duties, or from reckless
disregard of their duties and obligations thereunder.

Portfolio Transactions
- ----------------------

         Pursuant to the Investment Advisory Agreement with respect to each
Fund, other than the Diversified Equity Fund, the Adviser determines, subject to
the general supervision of the Board of Trustees of the Group and in accordance
with each such Fund's investment objective and restrictions, which securities
are to be purchased and sold by a Fund, and which brokers are to be eligible to
execute such Fund's portfolio transactions. Pursuant to the Sub-Investment
Advisory Agreements, the Sub-Advisers determine, subject to the supervision of
the Adviser and the overall general supervision of the Group's Board of Trustees
and in accordance with the Diversified Equity Fund's respective investment
objective and policies, which securities are to be purchases and sold by such
Fund, and which brokers are to be eligible to execute such Fund's portfolio
transactions.

                                      B-22


<PAGE>   65




         Purchases and sales of portfolio securities with respect to the Income
Fund, the Intermediate Tax-Free Fund and the Money Market Fund usually are
principal transactions in which portfolio securities are normally purchased
directly from the issuer or from an underwriter or market maker for the
securities. Purchases from underwriters of portfolio securities generally
include a commission or concession paid by the issuer to the underwriter, and
purchases from dealers serving as market makers may include the spread between
the bid and asked price.

         Transactions on stock exchanges involve the payment of negotiated
brokerage commissions. Transactions in the over-the-counter market are generally
principal transactions with dealers. With respect to the over-the-counter
market, the Group, where possible, will deal directly with dealers who make a
market in the securities involved except in those circumstances where better
price and execution are available elsewhere.

         Allocation of transactions, including their frequency, to various
brokers and dealers is determined by the Adviser or the applicable Sub-Adviser,
as the case may be, in its best judgment and in a manner deemed fair and
reasonable to Shareholders. The primary consideration is prompt execution of
orders in an effective manner at the most favorable price. Subject to this
consideration, brokers and dealers who provide supplemental investment research
to the Adviser or the applicable Sub-Adviser, as the case may be, may receive
orders for transactions on behalf of the Funds. The Adviser and each Sub-Adviser
are authorized to pay a broker-dealer who provides such brokerage and research
services a commission for executing each such Fund's brokerage transactions
which is in excess of the amount of commission another broker would have charged
for effecting that transaction if, but only if, the Adviser or Sub-Adviser, as
the case may be, determines in good faith that such commission was reasonable in
relation to the value of the brokerage and research services provided by such
broker viewed in terms of that particular transaction or in terms of all of the
accounts over which it exercises investment discretion. Any such research and
other statistical and factual information provided by brokers to a Fund or to
the Adviser or Sub-Adviser, as the case may be, is considered to be in addition
to and not in lieu of services required to be performed by such Adviser or
Sub-Adviser under its respective agreement regarding management of the Fund. The
cost, value and specific application of such information are indeterminable and
hence are not practicably allocable among the Funds and other clients of the
Adviser or Sub-Adviser, as the case may be, who may indirectly benefit from the
availability of such information. Similarly, the Funds may indirectly benefit
from information made available as a result of transactions effected for such
other clients. Under the Investment Advisory Agreement and Sub-Advisory
Agreements, the Adviser and Sub-Advisers are permitted to pay higher brokerage
commissions for brokerage and research

                                      B-23


<PAGE>   66



services in accordance with Section 28(e) of the Securities Exchange Act of
1934. In the event the Adviser and/or the Sub-Advisers do follow such a 
practice, they will do so on a basis which is fair and equitable to the 
Group and the Funds.

         While the Adviser and the Sub-Advisers generally seek competitive
commissions, the Group may not necessarily pay the lowest commission available
on each brokerage transaction, for reasons discussed above.

         Except as otherwise disclosed to the Shareholders of the Funds and as
permitted by applicable laws, rules and regulations, the Group will not, on
behalf of the Funds, execute portfolio transactions through, acquire portfolio
securities issued by, make savings deposits in, or enter into repurchase or
reverse repurchase agreements with the Adviser, the Sub-Advisers, BISYS, or
their affiliates, and will not give preference to the Adviser's correspondents
with respect to such transactions, securities, savings deposits, repurchase
agreements, and reverse repurchase agreements.

         Investment decisions for each Fund are made independently from those
for the other Funds, other funds of the Group or any other investment company or
account managed by the Adviser or any of the Sub-Advisers. Any such other fund,
investment company or account may also invest in the same securities as the
Group on behalf of the Funds. When a purchase or sale of the same security is
made at substantially the same time on behalf of a Fund and another fund of the
Group, investment company or account, the transaction will be averaged as to
price and available investments will be allocated as to amount in a manner which
the Adviser or the Sub-Adviser, as the case may be, believes to be equitable to
the Fund and such other fund, 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. To the extent permitted by
law, the Adviser and the Sub-Advisers may aggregate the securities to be sold or
purchased for a Fund with those to be sold or purchased for the other Funds or
for other investment companies or accounts in order to obtain best execution. As
provided by the Investment Advisory Agreement and the Sub-Advisory Agreements,
in making investment recommendations for the Funds, neither the Adviser nor any
Sub-Adviser will inquire or take into consideration whether an issuer of
securities proposed for purchase or sale by the Group is a customer of the
Adviser, any Sub-Adviser, any of their parents or subsidiaries or affiliates
and, in dealing with its customers, the Adviser, the Sub-Advisers, their
respective parents, subsidiaries, and affiliates will not inquire or take into
consideration whether securities of such customers are held by the Funds or any
other fund of the Group.

Glass-Steagall Act
- ------------------

         In 1971, the United States Supreme Court held in INVESTMENT COMPANY
INSTITUTE V. CAMP that the Federal statute commonly referred to as the
Glass-Steagall Act prohibits a national bank from operating a mutual fund for
the collective investment of managing agency accounts. Subsequently, the Board
of Governors of the Federal Reserve System (the "Board") issued a regulation and
interpretation to the effect that the Glass-Steagall Act and such decision: (a)
forbid a bank holding company registered under the Federal Bank Holding Company
Act of 1956 (the "Holding Company Act") or any non-bank affiliate thereof from
sponsoring, organizing, or controlling a registered, open-end investment company
continuously engaged in the issuance of its shares, but (b) do not prohibit such
a holding company or affiliate from acting as investment adviser, transfer
agent, and custodian to such an investment company. In 1981, the United States
Supreme Court held in BOARD OF GOVERNORS OF THE FEDERAL RESERVE SYSTEM V.
INVESTMENT COMPANY INSTITUTE that the Board did not exceed its authority under
the Holding Company Act when it adopted its regulation and interpretation
authorizing bank holding companies and their non-bank affiliates to act as
investment advisers to registered closed-end investment companies. In the BOARD
OF GOVERNORS case, the Supreme Court also stated that if a national bank
complied with the restrictions imposed by the Board in its regulation and
interpretation authorizing bank holding companies and their non-bank affiliates
to act as investment advisers to investment companies, a national bank
performing investment advisory services for an investment company would not
violate the Glass-Steagall Act.

   
         The Adviser believes that it possesses the legal authority to perform
the services for the Funds contemplated by the Prospectus, this Statement of
Additional Information and the Investment Advisory Agreement without violation
of applicable statutes and regulations. Future changes in either Federal or
state statutes and regulations relating to the permissible activities of banks
or bank holding companies and the subsidiaries or affiliates of those entities,
as well as further judicial or administrative decisions or interpretations of
present and future statutes and regulations, could prevent or restrict the
Adviser from continuing to perform such services for the Group. In addition,
current state securities laws on the issue of the registration of banks as 
brokers or dealers may differ from the interpretation of federal law, and banks
and financial institutions may be required to register as dealers pursuant to
the laws of a specific state. Depending upon the nature of any changes in the
services which
    

                                      B-25


<PAGE>   68

   
could be provided by the Adviser, the Board of Trustees of the Group would
review the Group's relationship with the Adviser and consider taking all action
necessary in the circumstances.

         Should future legislative, judicial, or administrative action prohibit
or restrict the proposed activities of the Adviser and/or the Adviser's
affiliated and correspondent banks in connection with Customer purchases of
Shares of any of the Funds, those banks might be required to alter materially or
discontinue the services offered by them to Customers. It is not anticipated,
however, that any change in the Group's method of operations would affect its
net asset value per share or result in financial losses to any Customer.
    

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

         BISYS serves as administrator (the "Administrator") to the Funds
pursuant to a Management and Administration Agreement dated as of August 20,
1996 (the "Administration Agreement"). The Administrator assists in supervising
all operations of each Fund (other than those performed by the Adviser under the
Investment Advisory Agreement, by the Sub-Advisers under the Sub-Advisory
Agreements, by The Fifth Third Bank under the Custody Agreement and by BISYS
Fund Services, Inc. under the Transfer Agency Agreement and Fund Accounting
Agreement). The Administrator is a broker-dealer registered with the Commission,
and is a member of the National Association of Securities Dealers, Inc. The
Administrator provides financial services to institutional clients.
    

         Under the Administration Agreement, the Administrator has agreed to
maintain office facilities; furnish statistical and research data, clerical,
certain bookkeeping services and stationery and office supplies; prepare the
periodic reports to the Commission on Form N-SAR or any replacement forms
therefor; compile data for, assist the Trust or its designee in the preparation
of, and file all of the Funds' federal and state tax returns and required tax
filings other than those required to be made by the Funds' custodian and
Transfer Agent; prepare compliance filings pursuant to state securities laws
with the advice of the Group's counsel; assist to the extent requested by the
Group with the Group's preparation of its Annual and Semi-Annual Reports to
Shareholders and its Registration Statement (on Form N-1A or any replacement
therefor); compile data for, prepare and file timely Notices to the Commission
required pursuant to Rule 24f-2 under the 1940 Act; keep and maintain the
financial accounts and records of each Fund, including calculation of daily
expense accruals; periodic review of the amount of the deviation, if any, of the
Money Market Fund's current net asset value per share (calculated using
available market quotations or an appropriate substitute that reflects current
market conditions) from such Fund's amortized cost

                                      B-26


<PAGE>   69



price per share; and generally assist in all aspects of the Funds' operations
other than those performed by the Adviser under the Investment Advisory
Agreement, by the Sub-Advisers under the Sub-Investment Advisory Agreements, by
The Fifth Third Bank under the Custody Agreement and by BISYS Fund Services,
Inc. under the Transfer Agency Agreement and Fund Accounting Agreements. Under
the Administration Agreement, the Administrator may delegate all or any part of
its responsibilities thereunder.

         The Administrator receives a fee from each Fund for its services as
Administrator and expenses assumed pursuant to the Administration Agreement,
equal to a fee calculated daily and paid periodically, at the annual rate equal
to twenty one-hundredths of one percent (.20%) of that Fund's average daily net
assets.

         Unless sooner terminated as provided therein, the Administration
Agreement has an initial term expiring on August 20, 1999. The Administration
Agreement thereafter shall be renewed automatically for successive one-year
terms, unless written notice not to renew is given by the non-renewing party to
the other party at least 60 days prior to the expiration of the then-current
term. The Administration Agreement is terminable with respect to a particular
Fund only upon mutual agreement of the parties to the Administration Agreement
and for cause (as defined in the Administration Agreement) by the party alleging
cause, on not less than 60 days' notice by the Group's Board of Trustees or by
the Administrator.

         The Administration Agreement provides that the Administrator shall not
be liable for any error of judgment or mistake of law or any loss suffered by
any Fund in connection with the matters to which the Administration Agreement
relates, except a loss resulting from willful misfeasance, bad faith, or
negligence in the performance of its duties, or from the reckless disregard by
the Administrator of its obligations and duties thereunder.

Expenses
- --------

         If total expenses borne by any of the Funds in any fiscal year exceed
expense limitations imposed by applicable state securities regulations, the
Adviser and the Administrator will reimburse that Fund by the amount of such
excess in proportion to their respective fees. As of the date of this Statement
of Additional Information, the most restrictive expense limitation applicable to
the Funds limits each Fund's aggregate annual expenses, including management and
advisory fees but excluding interest, taxes, brokerage commissions and certain
other expenses, to 2 1/2% of the first $30 million of the Fund's average net
assets, 2% of the next $70 million of the Fund's average net assets, and 1/2% of
the Fund's remaining average net assets. Any expense reimbursements will be
estimated daily and reconciled and paid on a monthly basis. Fees

                                      B-27


<PAGE>   70



imposed upon customer accounts by the Adviser or its affiliated or correspondent
banks for cash management services would not be included within Fund expenses
for purposes of any such expense limitation.

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

         BISYS serves as agent for each of the Funds in the distribution of its
Shares pursuant to a Distribution Agreement dated as of August 20, 1996 (the
"Distribution Agreement"). Unless otherwise terminated, the Distribution
Agreement will continue in effect until August 20, 1998, and year to year
thereafter for successive annual periods ending on August 20, if, as to each
Fund, such continuance is approved at least annually by (i) by the Group's Board
of Trustees or by the vote of a majority of the outstanding shares of that Fund,
and (ii) by the vote of a majority of the Trustees of the Group who are not
parties to the Distribution Agreement or interested persons (as defined in the
1940 Act) of any party to the Distribution Agreement, cast in person at a
meeting called for the purpose of voting on such approval. The Distribution
Agreement may be terminated in the event of any assignment, as defined in the
1940 Act.
    

         In its capacity as Distributor, BISYS solicits orders for the sale of
Shares, advertises and pays the costs of advertising, office space and the
personnel involved in such activities. BISYS receives no compensation under the
Distribution Agreement with the Group, but may retain all or a portion of the
sales charge imposed upon sales of Shares of each of the Funds.

         As described in the Prospectus, the Group has adopted a Distribution
and Shareholder Service Plan (the "Plan") with respect to the Funds pursuant to
Rule 12b-1 under the 1940 Act under which each Fund is authorized to pay BISYS
in an amount not in excess, on an annual basis, of 0.25% of the average daily
net asset value of the Shares of that Fund (the "12b-1 Fee"). Payments of the
12b-1 Fee to BISYS will be used (i) to compensate Participating Organizations
(as defined below) for providing distribution assistance relating to a Fund's
Shares, (ii) for promotional activities intended to result in the sale of Shares
and distribution of prospectuses to other than current shareholders, and (iii)
to compensate Participating Organizations for providing shareholder services
with respect to their customers who are, from time to time, beneficial and
record holders of Shares. Participating Organizations include banks (including
affiliates of the Adviser), broker-dealers, the Adviser, BISYS and other
institutions. Payments to such Participating Organizations may be made pursuant
to agreements entered into with BISYS.

         As required by Rule 12b-1, the Plan was approved by the initial
Shareholder of each of the Funds and by the Board of

                                      B-28


<PAGE>   71



Trustees, including a majority of the Trustees who are not interested persons of
any of the Funds and who have no direct or indirect financial interest in the
operation of the Plan (the "Independent Trustees"). The Plan may be terminated
as to a Fund by vote of a majority of the Independent Trustees, or by vote of
majority of the outstanding Shares of that Fund. Any change in the Plan that
would materially increase the distribution cost to a Fund requires Shareholder
approval. The Trustees review quarterly a written report of such costs and the
purposes for which such costs have been incurred. The Plan may be amended by
vote of the Trustees including a majority of the Independent Trustees, cast in
person at a meeting called for that purpose. For so long as the Plan is in
effect, selection and nomination of those Trustees who are not interested
persons of the Group shall be committed to the discretion of such disinterested
persons. All agreements with any person relating to the implementation of the
Plan may be terminated at any time on 60 days' written notice without payment of
any penalty, by vote of a majority of the Independent Trustees or by a vote of
the majority of the outstanding Shares of the Fund. The Plan will continue in
effect for successive one-year periods, provided that each such continuance is
specifically approved (i) by the vote of a majority of the Independent Trustees,
and (ii) by a vote of a majority of the entire Board of Trustees cast in person
at a meeting called for that purpose. The Board of Trustees has a duty to
request and evaluate such information as may be reasonably necessary for them to
make an informed determination of whether the Plan should be implemented or
continued. In addition the Trustees in approving the Plan must determine that
there is a reasonable likelihood that the Plan will benefit each Fund and its
Shareholders.

         The Board of Trustees of the Group believes that the Plan is in the
best interests of each Fund since it encourages Fund growth and maintenance of
Fund assets. As a Fund grows in size, certain expenses, and therefore total
expenses per Share, may be reduced and overall performance per Share may be
improved.

         BISYS may enter into, from time to time, Rule 12b-1 Agreements with
selected dealers pursuant to which such dealers will provide certain services in
connection with the distribution of a Fund's Shares including, but not limited
to, those discussed above.

Administrative Services Plan
- ----------------------------

         As described in the Prospectus, the Group has also adopted an
Administrative Services Plan (the "Services Plan") under which each Fund is
authorized to pay certain financial institutions, including the Adviser, its
correspondent and affiliated banks, and BISYS (a "Service Organization"), to

Service Organizations are made pursuant to Servicing Agreements between the
Group and the Service Organization. The Services Plan authorizes each Fund to
make payments to Service Organizations in an amount, on an annual basis, of up
to 0.25% of the average daily net asset value of that Fund. The Services Plan
has been approved by the Board of Trustees of the Group, including a majority of
the Trustees who are not interested persons of the Group (as defined in the 1940
Act) and who have no direct or indirect financial interest in the operation of
the Services Plan or in any Servicing Agreements thereunder (the "Disinterested
Trustees"). The Services Plan may be terminated as to a Fund by a vote of a
majority of the Disinterested Trustees. The Trustees review quarterly a written
report of the amounts expended pursuant to the Services Plan and the purposes
for which such expenditures were made. The Services Plan may be amended by a
vote of the Trustees, provided that any material amendments also require the
vote of a majority of the Disinterested Trustees. For so long as the Services
Plan is in effect, selection and nomination of those Disinterested Trustees
shall be committed to the discretion of the Group's Disinterested Trustees. All
Servicing Agreements may be terminated at any time without the payment of any
penalty by a vote of a majority of the Disinterested Trustees. The Services Plan
will continue in effect for successive one-year periods, provided that each such
continuance is specifically approved by a majority of the Board of Trustees,
including a majority of the Disinterested Trustees. As of the date hereof, the
Group has not entered into any such servicing agreements.

                             ADDITIONAL INFORMATION

Description of Shares
- ---------------------

         The Group is an Ohio business trust.  The Group was organized
on April 25, 1988, and the Group's Declaration of Trust was filed

                                      B-31


<PAGE>   74



with the Secretary of State of Ohio on April 25, 1988. The Declaration of Trust
authorizes the Board of Trustees to issue an unlimited number of shares, which
are shares of beneficial interest, without par value. The Group presently has 14
series of shares, one of which represents interests in the Money Market Fund,
one of which represents interests in the Diversified Equity Fund, one of which
represents interests in the Income Equity Fund, one of which represents
interests in the Special Equity Fund, one of which represents interests in the
Income Fund and one of which represents interests in the Intermediate Tax-Free
Fund. The Group's Declaration of Trust authorizes the Board of Trustees to
divide or redivide any unissued shares of the Group into one or more additional
series by setting or changing in any one or more respects their respective
preferences, conversion or other rights, voting power, restrictions, limitations
as to dividends, qualifications, and terms and conditions of redemption.

         Shares have no subscription or preemptive rights and only such
conversion or exchange rights as the Board of Trustees may grant in its
discretion. When issued for payment as described in the Prospectus and this
Statement of Additional Information, the Shares will be fully paid and
non-assessable. In the event of a liquidation or dissolution of the Group,
shareholders of a fund are entitled to receive the assets available for
distribution belonging to that fund, and a proportionate distribution, based
upon the relative asset values of the respective funds, of any general assets
not belonging to any particular fund which are available for distribution.

         Rule 18f-2 under the 1940 Act provides that any matter required to be
submitted to the holders of the outstanding voting securities of an investment
company such as the Group shall not be deemed to have been effectively acted
upon unless approved by the holders of a majority of the outstanding shares of
each fund affected by the matter. For purposes of determining whether the
approval of a majority of the outstanding shares of a fund will be required in
connection with a matter, a fund will be deemed to be affected by a matter
unless it is clear that the interests of each fund in the matter are identical,
or that the matter does not affect any interest of the fund. Under Rule 18f-2,
the approval of an investment advisory agreement or any change in investment
policy would be effectively acted upon with respect to a fund only if approved
by a majority of the outstanding shares of such fund. However, Rule 18f-2 also
provides that the ratification of independent public accountants, the approval
of principal underwriting contracts, and the election of Trustees may be
effectively acted upon by shareholders of the Group voting without regard to
series.

         As of the date immediately preceding the public offering of the Fund's
Shares, BISYS Fund Services Ohio, Inc. owned all of the

                                      B-32


<PAGE>   75



issued and outstanding Shares of each of the Funds. It is anticipated that upon
commencement of the public offering of the Funds' Shares BISYS Fund Services
Ohio, Inc.'s holdings of Shares of each of the Funds will be reduced below 5%.

Vote of a Majority of the Outstanding Shares
- --------------------------------------------

         As used in the Prospectus and this Statement of Additional Information,
a "vote of a majority of the outstanding Shares" of a Fund means the affirmative
vote, at a meeting of Shareholders duly called, of the lesser of (a) 67% or more
of the votes of Shareholders of that Fund present at a meeting at which the
holders of more than 50% of the votes attributable to Shareholders of record of
that Fund are represented in person or by proxy, or (b) the holders of more than
50% of the outstanding votes of Shareholders of that Fund.

Additional Tax Information
- --------------------------

         Each of the Funds is treated as a separate entity for federal income
tax purposes and intends to qualify as a "regulated investment company" under
the Internal Revenue Code of 1986, as amended (the "Code") for so long as such
qualification is in the best interest of that Fund's shareholders. In order to
qualify as a regulated investment company, each Fund must, among other things:
derive at least 90% of its gross income from dividends, interest, payments with
respect to securities loans, and gains from the sale or other disposition of
securities or foreign currencies, or other income derived with respect to its
business of investing in such stock, securities, or currencies; derive less than
30% of its gross income from the sale or other disposition of stock, securities,
options, future contracts or foreign currencies held less than three months; and
diversify its investments within certain prescribed limits. In addition, to
utilize the tax provisions specially applicable to regulated investment
companies, each Fund must distribute to its Shareholders at least 90% of its
investment company taxable income for the year. In general, a Fund's investment
company taxable income will be its taxable income subject to certain adjustments
and excluding the excess of any net long-term capital gain for the taxable year
over the net short-term capital loss, if any, for such year.

         A non-deductible 4% excise tax is imposed on regulated investment
companies that do not distribute in each calendar year (regardless of whether
they otherwise have a non-calendar taxable year) an amount equal to 98% of their
ordinary income for the calendar year plus 98% of their capital gain net income
for the one-year period ending on October 31 of such calendar year. The balance
of such income must be distributed during the next calendar year. If
distributions during a calendar year were less than the

                                      B-33


<PAGE>   76



required amount, a Fund would be subject to a non-deductible excise tax equal to
4% of the deficiency.

         Although each Fund expects to qualify as a "regulated investment
company" and to be relieved of all or substantially all federal income taxes,
depending upon the extent of its activities in states and localities in which
its offices are maintained, in which its agents or independent contractors are
located, or in which it is otherwise deemed to be conducting business, a Fund
may be subject to the tax laws of such states or localities. In addition, if for
any taxable year a Fund does not qualify for the special tax treatment afforded
regulated investment companies, all of its taxable income will be subject to
federal tax at regular corporate rates (without any deduction for distributions
to its Shareholders). In such event, dividend distributions would be taxable to
Shareholders to the extent of earnings and profits, and would be eligible for
the dividends received deduction for corporations.

         It is expected that each Fund will distribute annually to Shareholders
all or substantially all of the Fund's net ordinary income and net realized
capital gains and that such distributed net ordinary income and distributed net
realized capital gains will be taxable income to Shareholders for federal income
tax purposes, even if paid in additional Shares of the Fund and not in cash.

         Distribution by a Fund of the excess of net long-term capital gain over
net short-term capital loss is taxable to Shareholders as long-term capital gain
in the year in which it is received, regardless of how long the Shareholder has
held the Shares. Such distributions are not eligible for the dividends-received
deduction.

         Federal taxable income of individuals is subject to graduated tax rates
of 15%, 28%, 31%, 36% and 39.6%. Further, the marginal tax rate may be in excess
of 39.6%, because adjustments reduce or eliminate the benefit of the personal
exemption and itemized deductions for individuals with gross income in excess of
certain threshold amounts.

         Capital gains of individuals are subject to tax at the same rates
applicable to ordinary income; however, the tax rate on long-term capital gains
of individuals cannot exceed 28%. Capital losses may be used to offset capital
gains. In addition, individuals may deduct up to $3,000 of net capital loss each
year to offset ordinary income. Excess net capital loss may be carried forward
and deducted in future years.

         Federal taxable income of corporations in excess of $75,000 up to $10
million is subject to a 34% tax rate; however, because the benefit of lower tax
rates on a corporation's taxable income of

                                      B-34


<PAGE>   77



less than $75,000 is phased out for corporations with income in excess of
$100,000 but lower than $335,000, a maximum marginal tax rate of 39% may result.
Federal taxable income of corporations in excess of $10 million is subject to a
tax rate of 35%. Further, a corporation's federal taxable income in excess of
$15 million is subject to an additional tax equal to 3% of taxable income over
$15 million, but not more than $100,000.

         Capital gains of corporations are subject to tax at the same rates
applicable to ordinary income. Capital losses may be used only to offset capital
gains and excess net capital loss may be carried back three years and forward
five years.

         Certain corporations are entitled to a 70% dividends received deduction
for distributions from certain domestic corporations. Each Fund will designate
the portion of any distributions which qualify for the 70% dividends received
deduction. The amount so designated may not exceed the amount received by the
Fund for its taxable year that qualifies for the dividends received deduction.
Because all of the Money Market Fund's and the Income Fund's net investment
income is expected to be derived from earned interest, it is anticipated that no
distributions from those Funds will qualify for the 70% dividends received
deduction.

         Foreign taxes may be imposed on a Fund by foreign countries with
respect to its income from foreign securities. Since less than 50% in value of
any one Fund's total assets at the end of its fiscal year are expected to be
invested in stocks or securities of foreign corporations, such Fund will not be
entitled under the Code to pass through to its Shareholders their pro rata share
of the foreign taxes paid by the Fund. These taxes will be taken as a deduction
by such Fund.

         Each Fund may be required by federal law to withhold and remit to the
U.S. Treasury 31% of taxable dividends, if any, and capital gain distributions
to any Shareholder, and the proceeds of redemption or the values of any
exchanges of Shares of a Fund, if such Shareholder (1) fails to furnish the Fund
with a correct taxpayer identification number, (2) under-reports dividend or
interest income, or (3) fails to certify to the Fund that he or she is not
subject to such withholding. An individual's taxpayer identification number is
his or her Social Security number.

         THE INTERMEDIATE TAX-FREE FUND. The Intermediate Tax-Free Fund is not
intended to constitute a balanced investment program and is not designed for
investors seeking capital appreciation or maximum tax-exempt income irrespective
of fluctuations in principal. Shares of the Intermediate Tax-Free Fund would not
be suitable for tax-exempt institutions and may not be suitable for retirement
plans qualified under Section 401 of the Code, H.R. 10 plans, and individual
retirement accounts, since such plans and

                                      B-35


<PAGE>   78



accounts are generally tax-exempt and, therefore, would not gain any additional
benefit from all or a portion of the Intermediate Tax-Free Fund's dividends
being tax-exempt and such dividends would be ultimately taxable to the
beneficiaries when distributed to them. In addition, the Intermediate Tax-Free
Fund may not be appropriate investments for entities which are "substantial
users," or "related persons" thereof, of facilities financed by private activity
bonds held by the Intermediate Tax-Free Fund.

         The Code permits a regulated investment company which invests in Exempt
Securities to pay to its Shareholders "exempt-interest dividends," which are
excluded from gross income for federal income tax purposes, if at the close of
each quarter of its taxable year at least 50% of its total assets consist of
Exempt Securities.

         An exempt-interest dividend is any dividend or part thereof (other than
a capital gain dividend) paid by the Intermediate Tax-Free Fund that is derived
from interest received by the Intermediate Tax-Free Fund that is excluded from
gross income for federal income tax purposes, net of certain deductions,
provided the dividend is designated as an exempt-interest dividend in a written
notice mailed to Shareholders not later than sixty days after the close of the
Intermediate Tax-Free Fund's taxable year. The percentage of the total dividends
paid by the Intermediate TaxFree Fund during any taxable year that qualifies as
exempt-interest dividends will be the same for all Shareholders of the
Intermediate Tax-Free Fund receiving dividends during such year. Exemptinterest
dividends shall be treated by the Intermediate Tax-Free Fund's Shareholders as
items of interest excludable from their gross income for Federal income tax
purposes under Section 103(a) of the Code. However, a Shareholder is advised to
consult his tax adviser with respect to whether exempt-interest dividends retain
the exclusion under Section 103(a) of the Code if such Shareholder is a
"substantial user" or a "related person" to such user under Section 147(a) of
the Code with respect to any of the Exempt Securities held by the Intermediate
Tax-Free Fund. If a Shareholder receives an exempt-interest dividend with
respect to any Share and such Share is held by the Shareholder for six months or
less, any loss on the sale or exchange of such Share shall be disallowed to the
extent of the amount of such exempt-interest dividend.

         In general, interest on indebtedness incurred or continued by a
Shareholder to purchase or carry Shares is not deductible for federal income tax
purposes if the Intermediate Tax-Free Fund distributes exempt-interest dividends
during the Shareholder's taxable year. A Shareholder of the Intermediate
Tax-Free Fund that is a financial institution may not deduct interest expense
attributable to indebtedness incurred or continued to purchase or carry Shares
of the Intermediate Tax-Free Fund if the Intermediate Tax-Free Fund distributes
exempt-interest dividends during the Shareholder's

                                      B-36


<PAGE>   79



taxable year. Certain federal income tax deductions of property and casualty
insurance companies holding Shares of the Intermediate Tax-Free Fund and
receiving exempt-interest dividends may also be adversely affected. In certain
limited instances, the portion of Social Security benefits received by a
Shareholder which may be subject to federal income tax may be affected by the
amount of tax-exempt interest income, including exempt-interest dividends
received by Shareholders of the Intermediate Tax-Free Fund.

         In the event the Intermediate Tax-Free Fund realizes long-term capital
gains, such Fund intends to distribute any realized net long-term capital gains
annually. If the Intermediate Tax-Free Fund distributes such gains, such Fund
will have no tax liability with respect to such gains, and the distributions
will be taxable to Shareholders as long-term capital gains regardless of how
long the Shareholders have held their Shares. Any such distributions will be
designated as a capital gain dividend in a written notice mailed by the
Intermediate Tax-Free Fund to the Shareholders not later than sixty days after
the close of the Intermediate Tax-Free Fund's taxable year. It should be noted,
however, that capital gains are taxed like ordinary income except that net
capital gains of individuals are subject to a maximum federal income tax rate of
28%. Net capital gains are the excess of net long-term capital gains over net
short-term capital losses. Any net short-term capital gains are taxed at
ordinary income tax rates. If a Shareholder receives a capital gain dividend
with respect to any Share and then sells the Share before he has held it for
more than six months, any loss on the sale of the Share is treated as long-term
capital loss to the extent of the capital gain dividend received.

         For taxable years of corporations beginning before 1996 (and pursuant
to legislation proposed, but not yet enacted, thereafter), the Superfund Revenue
Act of 1986 imposes an additional tax (which is deductible for federal income
tax purposes) on a corporation at a rate of 0.12 of one percent on the excess
over $2,000,000 of such corporation's "modified alternative minimum taxable
income", which would include a portion of the exempt-interest dividends
distributed by the Intermediate Tax-Free Fund to such corporation. In addition,
exempt-interest dividends distributed to certain foreign corporations doing
business in the United States could be subject to a branch profits tax imposed
by Section 884 of the Code.

         Distributions of exempt-interest dividends by the Intermediate Tax-Free
Fund may be subject to state and local taxes even though a substantial portion
of such distributions may be derived from interest on obligations which, if
received directly, would be exempt from such taxes. The Intermediate Tax-Free
Fund will report to its Shareholders annually after the close of its taxable
year the percentage and source, on a state-by-state basis, of interest income
earned on municipal obligations held by the Intermediate

                                      B-37


<PAGE>   80



Tax-Free Fund during the preceding year. Shareholders are advised to consult
their tax advisers concerning the application of state and local taxes.

         As indicated in the Prospectus, the Intermediate Tax-Free Fund may
acquire rights regarding specified portfolio securities under puts. See
"INVESTMENT OBJECTIVES AND POLICIES -- Additional Information on Portfolio
Instruments - Puts" in this Statement of Additional Information. The policy of
the Intermediate Tax-Free Fund is to limit its acquisition of puts to those
under which it will be treated for federal income tax purposes as the owner of
the Exempt Securities acquired subject to the put and the interest on the Exempt
Securities will be tax-exempt to it. Although the Internal Revenue Service has
issued a published ruling that provides some guidance regarding the tax
consequences of the purchase of puts, there is currently no guidance available
from the Internal Revenue Service that definitively establishes the tax
consequences of many of the types of puts that the Intermediate Tax-Free Fund
could acquire under the 1940 Act. Therefore, although the Intermediate Tax-Free
Fund will only acquire a put after concluding that it will have the tax
consequences described above, the Internal Revenue Service could reach a
different conclusion.

         Income itself exempt from Federal income taxation may be considered in
addition to taxable income when determining whether Social Security payments
received by a Shareholder are subject to federal income taxation.

         Information set forth in the Prospectus and this Statement of
Additional Information which relates to Federal taxation is only a summary of
some of the important Federal tax considerations generally affecting purchasers
of Shares of a Fund. No attempt has been made to present a detailed explanation
of the Federal income tax treatment of a Fund or its Shareholders and this
discussion is not intended as a substitute for careful tax planning.
Accordingly, potential purchasers of Shares of a Fund are urged to consult their
tax advisers with specific reference to their own tax situation.

         In addition, the tax discussion in the Prospectus and this Statement of
Additional Information is based on tax laws and regulations which are in effect
on the date of the Prospectus and this Statement of Additional Information; such
laws and regulations may be changed by legislative or administrative action. As
of the date hereof, several proposals have been introduced by the 104th
Congress, which if enacted, could affect much of the information contained in
this section. However, it is not possible at this time to assess which, if any,
of such proposals will be acted upon and the effect thereof, if any, on this
information.

<PAGE>   81



         Information as to the federal income tax status of all distributions
will be mailed annually to each Shareholder.

Seven-Day Yield of the Money Market Fund
- ----------------------------------------

         The standardized seven-day yield for the Money Market Fund is computed
by determining the net change, exclusive of capital changes, in the value of a
hypothetical preexisting account in the Money Market Fund having a balance of
one Share at the beginning of the period, subtracting a hypothetical charge
reflecting deductions from Shareholder accounts, and dividing the difference by
the value of the account at the beginning of the base period to obtain the base
period return, and then multiplying the base period return by (365/7). The net
change in the account value of the Money Market Fund includes the value of
additional Shares purchased with dividends from the original Share, dividends
declared on both the original Share and any such additional Shares, and all
fees, other than nonrecurring account or sales charges, that are charged to all
Shareholder accounts in proportion to the length of the base period and assuming
the Money Market Fund's average account size. The capital changes to be excluded
from the calculation of the net change in account value are realized gains and
losses from the sale of securities and unrealized appreciation and depreciation.
The 30-day yield is calculated as described above except that the base period is
30 days rather than seven days.

         The effective yield for the Money Market Fund is computed by
compounding the base period return, as calculated above, by adding 1 to the base
period return raising the sum to a power equal to 365 divided by seven and
subtracting 1 from the result.

Yields of the Other Funds
- -------------------------

         As summarized in the Prospectus under the heading "PERFORMANCE
INFORMATION," yields of the Funds, other than the Money Market Fund, will be
computed by annualizing net investment income per share for a recent 30-day
period and dividing that amount by a Fund Share's maximum offering price
(reduced by any undeclared earned income expected to be paid shortly as a
dividend) on the last trading day of that period. Net investment income will
reflect amortization of any market value premium or discount of fixed income
securities (except for obligations backed by mortgages or other assets) and may
include recognition of a pro rata portion of the stated dividend rate of
dividend paying portfolio securities. The yield will vary from time to time
depending upon market conditions, the composition of the particular Fund's
portfolio and operating expenses of the Group allocated to each Fund. These
factors and possible differences in the methods used in calculating yield should
be considered when comparing a Fund's yield to yields published for other
investment companies and other investment vehicles. Yield should also be
considered relative to changes in

                                      B-39


<PAGE>   82



the value of a Fund's Shares and to the relative risks associated with the
investment objectives and policies of each of the Funds.

         In addition, with respect to the Intermediate Tax-Free Fund, tax
equivalent yields will be computed by dividing that portion of such Fund's yield
(as computed above) which is tax-exempt by one minus a stated income tax rate
and adding that result to that portion, if any, of the yield of that Fund which
is not tax-exempt.

Calculation of Total Return
- ---------------------------

         As summarized in the Prospectus under the heading "PERFORMANCE
INFORMATION," average annual total return is a measure of the change in value of
an investment in a Fund over the period covered, which assumes any dividends or
capital gains distributions are reinvested in the Fund immediately rather than
paid to the investor in cash. Average annual total return will be calculated by:
(1) adding to the total number of Shares purchased by a hypothetical $1,000
investment in that Fund all additional Shares which would have been purchased if
all dividends and distributions paid or distributed during the period had been
immediately reinvested; (2) calculating the value of the hypothetical initial
investment of $1,000 as of the end of the period by multiplying the total number
of Shares owned at the end of the period by the net asset value per share on the
last trading day of the period; (3) assuming redemption at the end of the
period; and (4) dividing this account value for the hypothetical investor by the
initial $1,000 investment and annualizing the result for periods of less than
one year. Each Fund, however, may also advertise aggregate total return in
addition to average annual total return. Aggregate total return is a measure of
the change in value of an investment in a Fund over the relevant period and is
calculated similarly to average annual total return except that the result is
not annualized.

Distribution Rates
- ------------------

         Each of the Funds, other than the Money Market Fund, may from time to
time advertise current distribution rates which are calculated in accordance
with the method disclosed in the Prospectus.

Performance Comparisons
- -----------------------

         Investors may judge the performance of the Funds by comparing them to
the performance of other mutual funds or mutual fund portfolios with comparable
investment objectives and policies through various mutual fund or market indices
such as those prepared by Dow Jones & Co., Inc. and Standard & Poor's
Corporation and to data prepared by Lipper Analytical Services, Inc., a widely
recognized independent service which monitors the performance of mutual funds.
Comparisons may also be made to indices or data

Trustees, serve for a term lasting until the next meeting of shareholders at
which Trustees are elected. Such meetings are not required to be held at any
specific intervals. Generally, shareholders owning not less than 20% of the
outstanding shares of the Group entitled to vote may cause the Trustees to call
a special meeting. However, the Group has represented to the Commission that the
Trustees will call a special meeting for the purpose of considering the removal
of one or more Trustees upon written request therefor from shareholders owning
not less than 10% of the outstanding votes of the Group entitled to vote. At
such a meeting, a quorum of shareholders (constituting a majority of votes
attributable to all outstanding shares of the Group), by majority vote, has the
power to remove one or more Trustees.

         The Group is registered with the Commission as a management investment
company. Such registration does not involve supervision by the Commission of the
management or policies of the Group.

                                    APPENDIX

         COMMERCIAL PAPER RATINGS. Commercial paper ratings of Standard & Poor's
Corporation ("S&P") are current assessments of the likelihood of timely payment
of debt considered short term in the relevant market. Commercial paper rated A-1
by S&P indicates that the degree of safety regarding timely payment is strong.
Those issues determined to possess extremely strong safety characteristics are
denoted A-1+. Commercial paper rated A-2 by S&P indicates that capacity for
timely payment on issues is satisfactory. However, the relative degree of safety
is not as high as for issues designated A-1. Commercial paper rated A-3 by S&P
indicates adequate capacity for timely payment. Such paper is, however, more
vulnerable to the adverse effects of changes in circumstances than obligations
carrying the higher designations. Commercial paper rated B by S&P is regarded as
having only speculative capacity for timely payment. Commercial paper rated C by
S&P is regarded as short-term obligations with a doubtful capacity for payment.
Commercial paper rated D by S&P is in payment default. The D rating category is
used when interest payments or principal payments are not made on the date due,
even if the applicable grace period has not expired, unless S&P believes that
such payments will be made during such grace period.

         Moody's Investors Service, Inc.'s ("Moody's") commercial paper rating
are opinions of the ability of issuers to repay punctually senior debt
obligations which have an original maturity not exceeding one year. The rating
Prime-1 is the highest commercial paper rating assigned by Moody's. Issuers
rated Prime-1 (or supporting institutions) are considered to have a superior
capacity 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.
Issuers rated Prime-2 (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 of Prime-1 rated issuers, but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variations. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternative liquidity is maintained.
Issuers rated Prime-3 (or supporting institutions) have a strong ability for
repayment of senior short-term debt obligations. The effects of industry
characteristics and market composition may be more pronounced. Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and the requirement for relatively high financial leverage.
Adequate

                                       A-1

alternate liquidity is maintained. Issuers rated Not Prime do not fall within
any of the Prime rating categories.

         Commercial paper rated F-1+ by Fitch Investors Service ("Fitch") is
regarded as having the strongest degree of assurance for timely payments.
Commercial paper rated F-1 by Fitch is regarded as having an assurance of timely
payment only slightly less than the strongest rating, i.e., F-1+. Commercial
paper rated F-2 by Fitch is regarded as having a satisfactory degree of
assurance of timely payment, but the margin of safety is not as great as for
issues assigned F-1+ or F-1 ratings. Commercial paper rated F-3 by Fitch is
regarded as having characteristics suggesting that the degree of assurance for
timely payment is adequate, however, near-term adverse changes could cause these
securities to be rated below investment grade. Commercial paper rated F-S by
Fitch is regarded as having characteristics suggesting a minimal degree of
assurance for timely payment and is vulnerable to near term adverse changes in
financial and economic conditions. Commercial paper rated D by Fitch is in
actual or imminent payment default.

         The description of the three highest short-term debt ratings by Duff &
Phelps, Inc. ("Duff") (Duff incorporates gradations of "1+" (one plus) and "1-"
(one minus) to assist investors in recognizing quality differences within the
highest rating category) are as follows. Duff 1+ is regarded as having the
highest certainty of timely payment. Short-term liquidity, including internal
operating factors and/or access to alternative sources of funds, is outstanding,
and safety is just below risk-free U.S. Treasury short-term obligations. Duff 1
is regarded as having a very high certainty of timely payment. Liquidity factors
are excellent and supported by good fundamental protection factors. Risk factors
are minor. Duff 1- is regarded as having a high certainty of timely payment.
Liquidity factors are strong and supported by good fundamental protection
factors. Risk factors are minor. Duff 2 is regarded as having a good certainty
of timely payment. Liquidity factors and company fundamentals are sound.
Although ongoing funding needs may enlarge total financing requirements, access
to capital markets is good. Risk factors are small. Duff 3 is regarded as having
a satisfactory liquidity and other protection factors qualify issue as to
investment grade. Risk factors are larger and subject to more variation.
Nevertheless, timely payment is expected. Duff 4 is considered as having
speculative investment characteristics. Liquidity is not sufficient to insure
against disruption in debt service. Operating factors and market access may be
subject to a high degree of variation. Duff 5 indicates that the issuer has
failed to meet scheduled principal and/or interest payments.

         Commercial paper rated A1 by IBCA Limited and its affiliate, IBCA Inc.
(collectively "IBCA") is regarded by IBCA as obligations supported by the
highest capacity for timely repayment. Where

                                       A-2


<PAGE>   87



issues possess a particularly strong credit feature, a rating of A1+ is
assigned. Obligations rated A2 are supported by a good capacity for timely
repayment. Obligations rated A3 are supported by a satisfactory capacity for
timely repayment. Obligations rated B are those for which there is an
uncertainty as to the capacity to ensure timely repayment. Obligations rated C
are those for which there is a high risk of default or which are currently in
default.

         The following summarizes the description of the three highest
short-term ratings of Thomson BankWatch, Inc. ("Thomson"). TBW-1 is the highest
category and indicates a very high likelihood that principal and interest will
be paid on a timely basis. TBW-2 is the second highest category indicating 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 is the lowest investment grade category and indicates that while
more susceptible to adverse developments (both internal and external) than
obligations with higher ratings, capacity to service principal and interest in a
timely fashion is considered adequate. TBW-4 is the lowest rating category and
is regarded as non-investment grade and therefore speculative.

         The plus (+) sign is used after a rating symbol to designate the
relative position of an issuer within the rating category.

         CORPORATE DEBT RATINGS. A S&P corporate debt rating is a current
assessment of the creditworthiness of an obligor with respect to a specific
obligation. Debt rated AAA has the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong. Debt rated AA has a very
strong capacity to pay interest and to repay principal and differs from the
highest rated issues only in small degree. Debt rated A has a strong capacity to
pay interest and repay principal although it is somewhat more susceptible to
adverse effects of changes in circumstances and economic conditions than debt in
higher rated categories.

         The following summarizes the three highest ratings used by Moody's for
corporate debt. Bonds that are rated Aaa by Moody's 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. Bonds
that are rated Aa 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 risks appear

                                       A-3


<PAGE>   88



somewhat larger than in Aaa securities. Bonds that are rated A by Moody's
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 some time in the future.

         Moody's applies numerical modifiers (1, 2, and 3) with respect to bonds
rated Aa through A. The modifier 1 indicates that the bond being rated ranks in
the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the bond ranks in the lower
end of its generic rating category.

         The following summarizes the three highest long-term debt ratings by
Duff. Debt rated AAA has the highest credit quality. The risk factors are
negligible being only slightly more than for risk-free U.S. Treasury debt. Debt
rated AA has a high credit quality and protection factors are strong. Risk is
modest but may vary slightly from time to time because of economic conditions.
Debt rated A has protection factors that are average but adequate. However, risk
factors are more variable and greater in periods of economic stress.

         To provide more detailed indications of credit quality, the ratings
from AA to A may be modified by the addition of a plus or minus sign to show
relative standing within this major rating category.

         The following summarizes the three highest long-term debt ratings by
Fitch (except for AAA ratings, plus or minus signs are used with a rating symbol
to indicate the relative position of the credit within the rating category).
Bonds rated AAA are considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events. Bonds rated AA are considered to be investment grade and of very high
credit quality. The obligor's ability to pay interest and repay principal is
very strong, although not quite as strong as bonds rated "AAA." Because bonds
rated in the "AAA" and "AA" categories are not significantly vulnerable to
foreseeable future developments, short-term debt of these issues is generally
rated "F-1+." Bonds rated as A are considered to be investment grade and of high
credit quality. The obligor's ability to pay interest and repay principal is
considered to be strong, but may be more vulnerable to adverse changes in
economic conditions and circumstances than bonds with higher ratings.

         The following summarizes IBCA's three highest long-term debt ratings.
Obligations rated AAA are those for which there is the lowest expectation of
investment risk. Capacity for timely repayment of principal and interest is
substantial, such that

                                       A-4


<PAGE>   89



adverse changes in business, economic or financial conditions are unlikely to
increase investment risk significantly. Obligations rated AA are those for which
there is a very low expectation of investment risk. Capacity for timely
repayment of principal and interest is substantial. Adverse changes in business,
economic, or financial conditions may increase investment risk albeit not very
significantly. Obligations rated A are those for which there is a low
expectation of investment risk. Capacity for timely repayment of principal and
interest is strong, although adverse changes in business, economic or financial
conditions may lead to increased investment risk.

         The following summarizes Thomson's description of its three highest
long-term debt ratings (Thomson may include a plus (+) or minus (-) designation
to indicate where within the respective category the issue is placed). AAA is
the highest category and indicates that the ability to repay principal and
interest on a timely basis is very high. AA is the second highest category and
indicates a superior ability to repay principal and interest on a timely basis
with limited incremental risk versus issues rated in the highest category. A is
the third highest category and indicates 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.

Municipal Obligations Ratings
- -----------------------------

         The following summarizes the three highest ratings used by Moody's for
state and municipal short-term obligations. Obligations bearing MIG-1 or VMIG-1
designations are of the best quality, enjoying strong protection by established
cash flows, superior liquidity support or demonstrated broad-based access to the
market for refinancing. Obligations rated MIG-2 or VMIG-2 denote high quality
with ample margins of protection although not so large as in the preceding
rating group. Obligations bearing MIG-3 or VMIG-3 denote favorable quality. All
security elements are accounted for but there is 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.

         S&P SP-1, SP-2, and SP-3 municipal note ratings (the three highest
ratings assigned) are described as follows:

                  "SP-1": Very strong or strong capacity to pay principal and
                  interest. Those issues determined to possess overwhelming
                  safety characteristics will be given a plus (+) designation.

                  "SP-2":  Satisfactory capacity to pay principal and
                  interest.

                                       A-5


<PAGE>   90



                  "SP-3":  Speculative capacity to pay principal and
                  interest.

         The following summarizes the three highest ratings used by Moody's for
state and municipal bonds:

                  "Aaa": Bonds judged to be of the best quality. They carry the
                  smallest degree of investment risk and are generally referred
                  to as "gilt edge." 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 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 risks appear somewhat larger than in Aaa
                  securities.

                  "A":  Bonds which 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.

         The following summarizes the three highest ratings used by S&P for
state and municipal bonds:

                  "AAA":  Debt which has the highest rating assigned by
                  S&P.  Capacity to pay interest and repay principal is
                  extremely strong.

                  "AA":  Debt which has a very strong capacity to pay
                  interest and repay principal and differs from the highest

                  rated issues only in small degree.

                  "A":  Debt which has a strong capacity to pay interest
                  and repay principal although it is somewhat more
                  susceptible to the adverse effects of changes in
                  circumstances and economic conditions than debt in higher
                  rated categories.

Definitions of Certain Money Market Instruments

Commercial Paper

         Commercial paper consists of unsecured promissory notes issued by
corporations. Issues of commercial paper normally have maturities of less than
nine months and fixed rates of return.

Certificates of Deposit

         Certificates of Deposit are negotiable certificates issued against
funds deposited in a commercial bank or a savings and loan association for a
definite period of time and earning a specified return.

Bankers' Acceptances

         Bankers' acceptances are negotiable drafts or bills of exchange,
normally drawn by an importer or exporter to pay for specific merchandise, which
are "accepted" by a bank, meaning, in effect, that the bank unconditionally
agrees to pay the face value of the instrument on maturity.

U.S. Treasury Obligations

         U.S. Treasury Obligations are obligations issued or guaranteed as to
payment of principal and interest by the full faith and credit of the U.S.
Government. These obligations may include Treasury bills, notes and bonds, and
issues of agencies and instrumentalities of the U.S. Government, provided such
obligations are guaranteed as to payment of principal and interest by the full
faith and credit of the U.S. Government.

U.S. Government Agency and Instrumentality Obligations

         Obligations of the U.S. Government include Treasury bills, certificates
of indebtedness, notes and bonds, and issues of agencies and instrumentalities
of the U.S. Government, such as the Government National Mortgage Association,
the Tennessee Valley Authority, the Farmers Home Administration, the Federal
Home Loan Banks, the Federal Intermediate Credit Banks, the Federal Farm Credit
Banks, the Federal Land Banks, the Federal Housing Administration, the Federal
National Mortgage Association, the Federal Home Loan Mortgage Corporation, and
the Student Loan Marketing Association. Some of these obligations, such as those
of the Government National Mortgage Association, are supported by the full faith
and credit of the U.S. Treasury; others, such as those of the Federal National
Mortgage Association, are supported by the right of the issuer to borrow from
the Treasury; others, such as those of the Student Loan Marketing 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 Federal

                                       A-7


<PAGE>   92


Farm Credit Banks, 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.
