                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Institutional Class shares of the MONEY MARKET, TREASURY MONEY MARKET and
CALIFORNIA TAX-FREE MONEY MARKET FUNDS (each a "Fund"). This summary is
qualified in its entirety by reference to the more detailed information provided
elsewhere in this Prospectus and in the Statement of Additional Information.
 
WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?  THE MONEY MARKET FUND seeks to
preserve principal value and maintain a high degree of liquidity while providing
current income. THE TREASURY MONEY MARKET FUND seeks to preserve principal value
and maintain a high degree of liquidity while providing current income. THE
CALIFORNIA TAX-FREE MONEY MARKET FUND seeks to preserve principal and maintain a
high degree of liquidity while providing current income exempt from federal and
California state personal income taxes. See "Investment Objectives."
 
WHAT ARE THE FUNDS' PERMITTED INVESTMENTS?  THE MONEY MARKET FUND invests in
obligations denominated in U.S. dollars including commercial paper, bank
obligations, thrift and savings and loan obligations, short-term corporate
obligations, general U.S. Government obligations and repurchase agreements
involving such obligations, receipts evidencing ownership of component parts of
U.S. Treasury obligations and securities issued or guaranteed by foreign
branches of foreign banks and foreign commercial paper. THE TREASURY MONEY
MARKET FUND invests exclusively in direct obligations issued by the U.S.
Treasury, separately traded component parts of such obligations transferrable
through the Federal book-entry system, and repurchase agreements involving such
obligations. THE CALIFORNIA TAX-FREE MONEY MARKET FUND invests in municipal
obligations of the State of California and its political subdivisions and
municipal obligations issued by territories or possessions of the United States.
See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUNDS?  Each Fund seeks to
maintain a net asset value of $1.00 per share. There can be no assurance that a
Fund will be able to maintain a net asset value of $1.00 per share on a
continuous basis. The California Tax-Free Money Market Fund concentrates its
investments in California municipal securities, and an investment in the Fund
therefore may be riskier than an investment in other types of money market
funds. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Institutional and Cash Sweep Class shares of the Trust and for the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve Wire System are open for business ("Business Days"). The
minimum initial investment in the Trust is $2,000. Shareholders must place
orders to purchase prior to 12:00 noon, Eastern time or orders to redeem prior
to 11:00 a.m., Eastern time for the California Tax-Free Money Market Fund, and
prior to 12:00 noon, Eastern time for the Money Market and Treasury Money Market
Funds on any Business Day. Otherwise the order will be effective the next
Business Day. In addition, effectiveness of a purchase is contingent on the
Custodian's receipt of Federal funds before 2:00 p.m., Eastern time. See
"Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  The net investment income (exclusive of short-term
capital gains) of the Funds is determined and declared on each Business Day as a
dividend for Shareholders of record as of the close of business on that day.
Dividends are paid monthly in additional shares unless the Shareholder elects to
take the payment in cash. See "Dividends."

(1) The Advisor has voluntarily agreed to waive fees to the extent necessary in
    order to limit "Total Operating Expenses" to not more than .45% for the
    Treasury Money Market Fund and .30% for the California Tax-Free Money Market
    Fund. The Advisor reserves the right to terminate its waiver at any time in
    its sole discretion. Absent fee waivers, the "Advisory Fees" and "Total
    Operating Expenses" would be .30% and .50%, for the Treasury Money Market
    Fund and California Tax Free Money Market Fund, respectively. "Total
    Operating Expenses" of the California Tax-Free Money Market Fund have been
    restated to reflect current fees and fee waivers.

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF A FUND AND SHOULD NOT
BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES MAY
BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist the
investor in understanding the various costs and expenses that may be directly or
indirectly borne by investors in the Institutional Class shares of the Funds.
Financial institutions that are the record owner of shares for the account of
their customers may impose separate fees for account services to their
customers. The Trust also offers Investment Class shares of the Funds which are
subject to the same expenses, except that Investment Class shares are subject to
certain distribution expenses. Additional information may be found under "The
Administrator" and "The Advisor."

open-end management investment company that offers units of beneficial interest

THE CALIFORNIA TAX-FREE MONEY MARKET FUND seeks to preserve principal and
maintain a high degree of liquidity while providing current income exempt from
federal and California state personal income taxes.
 
There can be no assurance that a Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
MONEY MARKET FUND
 
The Money Market Fund invests in obligations denominated in U.S. dollars
consisting of: (i) commercial paper (including Section 4(2) Commercial Paper)
issued by domestic and foreign issuers rated at least A-1 by Standard & Poor's
Corporation ("S&P") or Prime-1 by Moody's Investors Service ("Moody's") at the
time of investment or, if not rated, determined by the Advisor to be of
comparable quality; (ii) obligations (certificates of deposit, bank notes, time
deposits, and bankers' acceptances) of thrift institutions, savings and loans,
U.S. commercial banks (including foreign branches of such banks), and U.S. and
foreign branches of foreign banks, provided that such institutions (or, in the
case of a branch, the parent institution) have total assets of $1 billion or
more as shown on their last published financial statements at the time of
investment; (iii) short-term corporate obligations (including Rule 144A
Securities) with a remaining term of not more than 397 days of issuers with
commercial paper of comparable priority and security meeting the above ratings
criteria or determined by the Advisor to be of comparable quality; (iv)
obligations issued by the U.S. Government and backed by its full faith and
credit, and obligations issued or guaranteed as to principal and interest by the
agencies or instrumentalities of the U.S. Government (e.g., obligations issued
by Farmers Home Administration, Government National Mortgage Association,
Federal Farm Credit Bank and Federal Housing Administration); (v) receipts,
including TR's, TIGR's and CATS; (vi) repurchase agreements involving such
obligations; (vii) loan participations; (viii) readily marketable securities
backed by company receivables, truck and auto loans, leases, and credit card
loans provided that such instruments satisfy the rating requirements described
above or are determined by the Advisor to be of comparable quality and (ix) U.S.
dollar denominated securities issued or guaranteed by foreign governments, their
political subdivisions, agencies or instrumentalities, and obligations of
supranational entities such as the World Bank and the Asian Development Bank;
provided that the Fund invests no more than 5% of its assets in any such
instrument and invests no more than 25% of its assets in such instruments in the
aggregate. The Advisor will determine that the
<PAGE>   6
 
 6
 
permitted investments present minimal credit risks in accordance with guidelines
established by the Trust's Board of Trustees.
 
The Fund may concentrate its investments in certain instruments issued by U.S.
banks, U.S. branches of foreign banks and foreign branches of U.S. banks, but
only so long as the investment risk associated with investing in foreign
branches of domestic banks is the same as that associated with investing in
instruments issued by the U.S. parent, in that the U.S. parent would be
unconditionally liable in the event that the foreign branch failed to pay.
 
The Fund may invest up to 5% of its total assets in loan participations issued
by a bank in the United States with assets exceeding $1 billion where the
underlying loan is made to a borrower in whose obligations the Fund may invest
and the underlying loan has a remaining maturity of one year or less.
 
TREASURY MONEY MARKET FUND
 
The Treasury Money Market Fund invests exclusively in direct obligations issued
by the U.S. Treasury, separately traded component parts of such obligations
transferable through the Federal book-entry system ("STRIPS"), and repurchase
agreements involving such obligations.
 
The Fund is limited to making investments and engaging in investment
transactions that are permissible for federal credit unions.
 
Guarantees of the Fund's portfolio securities by the U.S. Government or its
agencies or instrumentalities guarantee only the principal and interest on the
guaranteed securities, and do not guarantee the securities' yield or value or
the yield or value of the Fund's shares.
 
CALIFORNIA TAX-FREE MONEY MARKET FUND
 
As a matter of fundamental policy, at least 80% of the California Tax-Free Money
Market Fund's assets are invested in obligations which produce interest that, in
the opinion of bond counsel, is exempt from Federal income tax and California
state personal income tax. These include obligations issued by the State of
California and its political subdivisions or municipal authorities and
obligations issued by territories or possessions of the United States.
Qualifying obligations consist of municipal notes; municipal bonds; floating or
variable rate municipal obligations; tax-exempt commercial paper; and shares of
open-end investment companies with similar investment objectives and policies.
 
The Advisor may engage in "put" transactions. The Advisor has discretion to
invest up to 20% of the Fund's assets in taxable money market instruments
(including repurchase agreements), securities which have not been registered
under the Securities Act of 1933 (Rule 144A Securities and Section 4(2)
Commercial Paper), receipts (including TR's, TIGR's and CATS), and securities,
the interest income from which is subject to the alternative minimum tax. While
the Fund generally intends to be fully invested in tax-exempt securities, the
Advisor may leave a portion of the Fund's assets uninvested.
 
For temporary defensive purposes when the Advisor determines that market
conditions warrant, the Fund may invest up to 100% of its assets in municipal
obligations of other states or taxable money market instruments (including
repurchase agreements, U.S. Treasury securities and instruments of certain U.S.
commercial banks or savings and loan institutions). The Fund will not be
pursuing its investment objective to the extent that more than 20% of its assets
are so invested in taxable money market securities.
 
The Fund will invest in obligations which are rated or are issued by entities
with debt obligations rated, at the time of investment, in one of the two
highest rating categories by S&P, Moody's or Fitch Investors Service, Inc.
("Fitch"), or, if not rated, determined by the Advisor to be of comparable
quality.
 
Opinions relating to the validity of municipal securities and to the exemption
of interest thereon from Federal income tax (and, with respect to California
municipal securities, to the exemption of
<PAGE>   7
 
 7
 
interest thereon from California state personal income tax) are rendered by bond
counsel to the respective issuers at the time of issuance. Neither the Fund nor
its Adviser will review the proceedings relating to the issuance of municipal
securities or the basis for such opinions.
 
GENERAL INVESTMENT POLICIES
 
Each Fund intends to comply with Rule 2a-7 adopted by the Securities and
Exchange Commission ("SEC"), which Rule permits money market funds to use the
amortized cost method for calculating net asset value. The Rule imposes certain
quality, maturity and diversification restraints on investments by a Fund. Under
the Rule, a Fund will invest only in U.S. dollar denominated securities, will
maintain an average maturity on a dollar-weighted basis of 90 days or less, and
will acquire only "eligible securities" that present minimal credit risks and
have a maturity of 397 days or less. For a further discussion, see the
"Description of Permitted Investments."
 
Each Fund may enter into forward commitments, or purchase securities on a
when-issued basis. A Fund is permitted to invest in when-issued securities where
such purchases are for investment and not for leveraging purposes; however, a
Fund may sell these securities before the settlement date if it is deemed
advisable. No additional forward commitments will be made if more than 20% of a
Fund's net assets would be so committed.
 
Each Fund may engage in securities lending, and will limit such practice to
33 1/3% of its total assets.
 
Each Fund will limit its investments in illiquid securities to 10% of its net
assets.
 
For further information, see "Description of Permitted Investments."
 
ELIGIBILITY UNDER FEDERAL CREDIT
UNION ACT
 
Shares of the Treasury Money Market Fund (the Fund) are designed to qualify as
eligible investments for federally chartered credit unions pursuant to Section
107(7), 107(8) and 107(15) of the Federal Credit Union Act and Part 703 of the
National Credit Union Administration Rules and Regulations. The Fund will
continually monitor changes in the applicable laws, rules and regulations
governing eligible investments, including new investments, for federally
chartered credit unions and will take such action as may be necessary to assure
that the Fund's investments, and, therefore, shares of the Fund, continue to
qualify as eligible investments under the Federal Credit Union Act.
 
Sections 107(7), 107(8) and 107(15) of the Federal Credit Union Act set forth
those securities, deposits and other obligations in which federally chartered
credit unions may invest. The Fund's investments consist exclusively of assets
designed to qualify as eligible investments if owned directly by a federally
chartered credit union. Shares of the Fund may or may not qualify as eligible
investments for particular state chartered credit unions. Accordingly, the Fund
encourages, but does not require, each state chartered credit union to consult
qualified legal counsel concerning whether the Fund's shares are permissible
investments for that credit union. While the Advisor will assure that the Fund
follows investment policies set forth herein, the Fund cannot be responsible for
compliance by participating state chartered credit unions with limitations on
permissible investments to which they may be subject.
 
RISK FACTORS
 
It is a fundamental policy of each Fund to use its best efforts to maintain a
constant net asset value of $1.00 per share. There can be no assurance that a
Fund will be able to maintain a stable net asset value of $1.00 per share.
 
Foreign securities which the Money Market Fund may purchase involve risks that
are different from investments in securities of U.S. issuers. These risks may
include future unfavorable political and economic developments, possible
withholding taxes, seizure of foreign deposits, currency controls, interest
limitations or other government
<PAGE>   8
 
 8
 
restrictions which might affect payment of principal or interest. Additionally,
there may be less public information available about foreign issuers. Foreign
branches of foreign banks are not regulated by U.S. banking authorities, and
foreign issuers generally are not bound by accounting, auditing and financial
reporting standards comparable to U.S. issuers.
 
Certain risks are inherent in the California Tax-Free Money Market Fund's
concentrated investment in California municipal securities, which may make an
investment in the Fund riskier than an investment in other types of money market
funds. These risks result from (1) amendments to the California Constitution and
other statutes that limit the taxing and spending authority of California
government entities, (2) the general financial condition of the State of
California, and (3) a variety of California laws and regulations that may
affect, directly or indirectly, California municipal securities. The ability of
issuers to pay interest on, or repay principal of, California municipal
securities may be impaired as a result. A more complete description of these
risks is contained in the Statement of Additional Information.
 
INVESTMENT LIMITATIONS
 
1. The Money Market Fund and the Treasury Money Market Fund may not purchase
securities of any issuer (except securities issued or guaranteed by the United
States its agencies or instrumentalities and repurchase agreements involving
such securities) if as a result more than 5% of the total assets of the Fund
would be invested in the securities of such issuer. While this restriction
applies to 75% of each Fund's assets, the Money Market Fund and the Treasury
Money Market Fund have each adopted, in accordance with Rule 2a-7, a policy
providing that the 5% limitation shall apply to 100% of the Fund's assets,
provided however, that each Fund may invest up to 25% of its assets in the First
Tier quality securities of a single issuer for up to three days. For purposes of
this limitation, loan participations are considered to be issued by both the
issuing bank and the underlying corporate borrower.
 
2. The California Tax-Free Money Market Fund may not purchase securities of any
issuer (except securities issued or guaranteed by the United States, its
agencies or instrumentalities) and repurchase agreements involving such
securities if as a result more than 5% of the total assets of the Fund would be
invested in the securities of such issuer.
 
3. Each Fund may not purchase any securities which would cause more than 25% of
its total assets to be invested in the securities of one or more issuers
conducting their principal business activities in the same industry, provided
that this limitation does not apply to investments in the obligations issued or
guaranteed by the U.S. Government or its agencies and instrumentalities and
repurchase agreements involving such securities, and provided further, that
utilities as a group will not be considered to be one industry, and wholly-owned
subsidiaries organized to finance the operations of their parent companies will
be considered to be in the same industries as their parent companies. For
purposes of this limitation, loan participations are considered to be issued by
both the issuing bank and the underlying corporate borrower, and supranational
entities are considered to be a separate industry. This limitation does not
apply to investments by the Money Market Fund in certain bank instruments. In
addition, this limitation applies only to the California Tax-Free Money Market
Fund's investments in taxable securities and securities issued or backed by the
revenues of non-governmental users.
 
4. Each Fund may not make loans, except that a Fund may (a) purchase or hold
debt instruments in accordance with its investment objective and policies; (b)
enter into repurchase agreements; and (c) engage in securities lending as
described in this Prospectus and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.

FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Funds. It is also a fundamental policy of each Fund
to use its best effort to maintain a constant net asset value of $1.00 per
share. Fundamental policies cannot be changed with respect to a Fund without the
consent of a majority of the Fund's outstanding shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of each Fund and continuously reviews,
supervises and administers the Funds' investment programs. The Advisor
discharges its responsibilities subject to the supervision of, and policies
established by, the Trustees of the Trust. The Trust's shares are not sponsored,
endorsed or guaranteed by, and do not constitute obligations or deposits of, the
Advisor and are not guaranteed by the FDIC or any other governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .30% of the average daily net assets of each Fund. The Advisor
may from time to time waive all or a portion of its fee in order to limit the
operating expenses of a Fund. Any such waiver is voluntary, and may be
terminated at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, predecessor of the
Advisor, was paid an advisory fee of .30%, .25% and .10% of the average daily
net assets of the Money Market, Treasury Money Market and California Tax-Free
Money Market Funds, respectively.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of each Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of a Fund's Institutional Class
shares. Any such waiver is voluntary, and may be terminated at any time in the
Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and
<PAGE>   10
 
 10
 
shareholder servicing agent for the Institutional and Cash Sweep Class shares of
the Trust and for the Investment Class shares of the Convertible Securities,
Government Securities, Emerging Growth, Blue Chip Growth and International
Equity Funds. Compensation for these services is paid under the Administration
Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days written notice by either party, or upon assignment by the
Distributor. Investment Class shares of the Funds may bear the costs of their
distribution expenses. It is possible that an institution may offer different
classes of shares to its customers, and thus receive different compensation with
respect to different classes of shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Funds may be made on days on which
both the New York Stock Exchange and Federal Reserve wire system are open for
business ("Business Days"). The minimum initial investment in a Fund is $2,000;
however, the minimum investment may be waived in the Distributor's discretion.
Shareholders may place orders by telephone.
 
Purchase orders will be effective on the Business Day made if the Distributor
receives an order before 12:00 noon, Eastern time on such Business Day.
Otherwise, the purchase order will be effective the next Business Day.
Effectiveness of a purchase order on any Business Day is contingent on the
Custodian's receipt of Federal funds before 2:00 p.m., Eastern time on such
Business Day. The purchase price is the net asset value per share, which is
expected to remain constant at $1.00. The net asset value per share is
calculated as of 12:00 noon, Eastern time, each Business Day based on the
amortized cost method. The net asset value per share of a Fund is determined by
dividing the total value of its investments and other assets, less any
liabilities, by the total number of its outstanding shares. The Trust reserves
the right to reject a purchase order when the Distributor determines that it is
not in the best interest of the Trust and/or Shareholder(s).
 
Shares of the Funds are offered only to residents of states in which the shares
are eligible for purchase.
 
The Trust is required to redeem for cash all full and fractional shares of the
Trust. The redemption price is the net asset value per share of a Fund (normally
$1.00 per share).
 
Redemption orders may be made any time before 11:00 a.m., Eastern time for the
California Tax-Free Money Market Fund and 12:00 noon, Eastern time for the Money
Market and Treasury Money Market Funds in order to receive that day's redemption
price (i.e. the next determined net asset value per share). For redemption
orders received before 12:00 noon, Eastern time, payment will be made the same
day by transfer of Federal funds. Otherwise, payment will be made on the next
Business Day. Redeemed shares are entitled to dividends declared the day the
redemption order is effective.
 
Neither the Trust's transfer agent nor the Trust will be responsible for any
loss, liability, cost or expense for acting upon wire instructions or upon
telephone instructions that it reasonably believes are genuine. The Trust and
its transfer agent will each employ reasonable procedures to confirm that
telephone instructions are genuine. Such procedures may include taping of
telephone conversations. If market conditions are extraordinarily active or
extraordinary circumstances exist, and you experience difficulties placing
redemption orders by telephone, you may wish to consider placing your order by
other means.

COMPUTATION OF YIELD
 
From time to time a Fund advertises its "current yield" and "effective compound
yield." Both yield figures are based on historical earnings and are not intended
to indicate future performance. The "current yield" of the Fund refers to the
income generated by an investment in the Fund 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 "effective yield" is calculated similarly but,
when annualized, the income earned by an investment in the Fund is assumed to be
reinvested. The "effective yield" will typically be slightly higher than the
"current yield" because of the compounding effect of this assumed reinvestment.
The California Tax Free Money Fund may also advertise tax-equivalent yields. The
California Tax-Free Money Market Fund may also advertise tax-equivalent yields.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
The yield of each Fund will fluctuate, and the annualization of a week's
dividend is not a representation by the Trust as to what an investment in the
Fund will actually yield in the future.
 
Each Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Funds may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Funds may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios,
and could include the value of a hypothetical investment in any of the capital
markets. The Funds may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Funds may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark, while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
TAXES
 
The following summary of federal and California income tax consequences is based
on current tax laws and regulations, which may be changed by legislative,
judicial or administrative action. No attempt has been made to present a
detailed explanation of the federal, state, or local income tax treatment of a
Fund or its Shareholders. In addition, state and local income tax consequences
on an investment in a Fund may differ from the federal income tax consequences
discussed below. Accordingly, Shareholders are urged to consult their tax
advisors regarding specific questions as to federal, state and local income
taxes. Additional information concerning taxes is set forth in the Statement of
Additional Information.
 
TAX STATUS OF THE FUNDS:
 
Each Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. Each Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
<PAGE>   12
 
 12
 
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on that part of its net investment income and net capital
gain (the excess of net long-term capital gain over net short-term capital loss)
distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
Each Fund will distribute all of its net investment income (including net
short-term capital gain) and net capital gain to Shareholders. Dividends from
net investment company taxable income are taxable to Shareholders as ordinary
income (whether received in cash or in additional shares) to the extent of the
Fund's earnings and profits. Distributions of net capital gain will be taxable
to Shareholders as long-term capital gain regardless of how long Shareholders
have held their shares and regardless of whether the distributions are received
in cash or in additional shares. Dividends and distributions of capital gain
paid by a Fund do not qualify for the dividends received deduction for corporate
shareholders. Each Fund will provide annual reports to Shareholders of the
federal income tax status of all distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments, a
Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because each Fund distributes
all of its net investment income to its shareholders, a Fund may have to sell
portfolio securities to distribute such imputed income, which may occur at a
time when the Advisor would not have chosen to sell such securities and which
may result in a taxable gain or loss.
 
Dividends declared by a Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
The Funds intend to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Income received on direct U.S. obligations is exempt from tax at the state level
when received directly by a Fund, and may be exempt, depending on the state,
when received by a Shareholder as income dividends from a Fund provided certain
state-specific conditions are satisfied. Interest received on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. Each Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from a Fund is considered tax exempt in their
particular state.
 
Income derived by the Money Market Fund from obligations of foreign issuers may
be subject to foreign withholding taxes. The Money Market Fund will not be able
to elect to treat Shareholders as having paid their proportionate share of such
foreign taxes.
 
Each sale, exchange, or redemption of Fund shares is a taxable event to the
Shareholder.
 
SPECIAL CONSIDERATIONS FOR THE CALIFORNIA TAX-FREE MONEY MARKET FUND
 
The California Tax-Free Money Market Fund will distribute all of its net
investment income (including net short-term capital gain) to Shareholders. If,
at the close of each quarter of its taxable year, at least 50% of the value of
the Fund's assets consists of obligations the interest on which is excludable
from gross income, the Fund may pay "exempt-interest dividends" to its
Shareholders. Those dividends constitute the portion of the aggregate dividends
as designated by the Fund, equal to the excess of the excludable interest over
certain amounts disallowed as deductions. Exempt-interest dividends are
excludable from a Shareholder's gross income for federal income tax purposes,
but may have certain collateral federal income tax consequences, as
<PAGE>   13
 
 13
 
described in the Statement of Additional Information.
 
Current federal tax law limits the types and volume of bonds qualifying for the
federal income tax exemption of interest, which may have an effect on the
ability of the Fund to purchase sufficient amounts of tax-exempt securities to
satisfy the Code's requirements for the payment of "exempt-interest" dividends.
 
Any dividends attributable to the Fund's taxable income will be taxable to
Shareholders as ordinary income (whether received in cash or in additional
shares) to the extent of the Fund's earnings and profits. None of the Fund's
distributions will qualify for the corporate dividends-received deduction.
 
Furthermore, entities or persons who are "substantial users" (or persons related
to "substantial users") of facilities financed by "private activity bonds" or
"industrial development bonds" should consult their tax advisors before
purchasing shares. (See the Statement of Additional Information.)
 
CALIFORNIA TAXES:
 
The Fund intends to qualify to pay dividends to Shareholders that are exempt
from California personal income tax ("California exempt-interest dividends").
The Fund will qualify to pay California exempt-interest dividends if (1) at the
close of each quarter of the Fund's taxable year, at least 50 percent of the
value of the Fund's total assets consists of obligations the interest on which
would be exempt from California personal income tax if the obligations were held
by an individual ("California Tax Exempt Obligations") and (2) the Fund
continues to qualify as a regulated investment company.
 
If the Fund qualifies to pay California exempt-interest dividends, dividends
distributed to Shareholders will be considered California exempt-interest
dividends (1) if they are designated as exempt-interest dividends by the Fund in
a written notice to Shareholders mailed within 60 days of the close of the
Fund's taxable year and (2) to the extent the interest received by the Fund
during the year on California Tax Exempt Obligations exceeds expenses of the
Fund that would be disallowed under California personal income tax law as
allocable to tax-exempt interest if the Fund were an individual. If the
aggregate dividends so designated exceed the amount that may be treated as
California exempt-interest dividends, only that percentage of each dividend
distribution equal to the ratio of aggregate California exempt-interest
dividends to aggregate dividends so designated will be treated as a California
exempt-interest dividend. The California Tax-Free Money Market Fund will notify
Shareholders of the amount of California exempt-interest dividends each year.
 
Corporations subject to California franchise tax that invest in the Fund may not
be entitled to exclude California exempt-interest dividends from income.
 
Dividend distributions that do not qualify for treatment as California
exempt-interest dividends will be taxable to Shareholders at ordinary income tax
rates for California personal income tax purposes to the extent of the Fund's
earnings and profits.
 
Interest on indebtedness incurred or continued by a Shareholder in connection
with the purchase of shares of the Fund will not be deductible for California
personal income tax purposes if the Fund distributes California exempt-interest
dividends.
 
The foregoing is a general, abbreviated summary of certain provisions of the
California Revenue and Taxation Code presently in effect as they directly govern
the taxation of Shareholders subject to California personal income tax. These
provisions are subject to change by legislative or administrative action, and
any such change may be retroactive with respect to Fund transactions.
Shareholders are advised to consult with their own tax advisors for more
detailed information concerning California tax matters.

for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each Fund or class will vote separately on matters relating solely to such Fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings, but approval will be sought for certain changes in the
operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon the written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate
assistance to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658.
 
DIVIDENDS
 
The net investment income (exclusive of net short-term capital gain) of the Fund
is determined and declared on each business day as a dividend for Shareholders
of record as of the close of business on that day. Dividends are paid by the
Fund in additional shares, unless the Shareholder has elected to take such
payment in cash, on the first business day of each month. Shareholders may
change their election by providing written notice to the Administrator at least
15 days prior to the change.
 
The amount of dividends payable on Institutional Class shares will typically be
higher than the dividends payable on Investment Class shares

because of the distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Funds:
 
ASSET-BACKED SECURITIES (NON-MORTGAGE)--Instruments secured by company
receivables, truck and auto loans, leases, and credit card receivables. Such
securities are generally issued as pass-through certificates, which represent
undivided fractional ownership interests in the underlying pools of assets. Such
securities also may be debt instruments, which are also known as collateralized
obligations and are generally issued as the debt of a special purpose entity,
such as a trust organized solely for purpose of owning such assets and issuing
such debt. The purchase of non-mortgage asset-backed securities raises risk
considerations peculiar to the financing of the instruments underlying such
securities. Asset-backed securities entail prepayment risk, which may vary
depending on the type of asset.
 
BANKERS' ACCEPTANCES--Bills of exchange or time drafts drawn on and accepted by
commercial banks. They are used by corporations to finance the shipment and
storage of goods and to furnish dollar exchange. Maturities are generally six
months or less.
 
CERTIFICATES OF DEPOSIT--Negotiable interest-bearing instruments with a specific
maturity. Certificates of deposit are issued by banks and savings and loan
institutions in exchange for the deposit of funds and normally can be traded in
the secondary market prior to maturity.
 
COMMERCIAL PAPER--Unsecured short-term promissory notes issued by corporations
and other entities. Maturities on these issues vary from a few days to nine
months. Purchase of such instruments involves a risk of default by the issuer.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
LOAN PARTICIPATIONS--Interests in loans to U.S. corporations (i.e., borrowers)
administered by the lending bank or agent for a syndicate of lending banks, and
sold by the lending bank or syndicate member ("intermediary bank"). Because the
intermediary bank does not guarantee a loan participation in any way, a loan
participation is subject to the credit risks generally associated with the
underlying corporate borrower. In addition, in the event the underlying
corporate borrower fails to pay principal and interest when due, the Fund may be
subject to delays, expenses and risks that are greater than those that would
have been involved if the Fund had purchased a direct obligation (such as
commercial paper) of such borrower. Moreover, the purchasing Fund may be
regarded as a creditor of the intermediary bank (rather than of the underlying
corporate borrower), making it subject to the risk that the issuing bank may
become insolvent. Further, in the event of the bankruptcy or insolvency of the
corporate borrower, a loan participation may be subject to certain defenses that
can be asserted by
<PAGE>   16
 
 16
 
such borrower as a result of improper conduct by the issuing bank. The secondary
market, if any, for these loan participations is limited, and any such
participation purchased by the Fund may be regarded as illiquid.
 
MUNICIPAL BONDS--Obligations issued by or on behalf of governments and political
sub-divisions thereof, including private activity bonds. The payment of the
principal and interest on such bonds is dependent solely on the ability of the
facility's user to meet its financial obligations and the pledge, if any, of
real and personal property so financed as security for such payment.
 
MUNICIPAL NOTES--Instruments issued by or on behalf of governments and political
sub-divisions thereof, and consist of general obligation notes, tax anticipation
notes, revenue anticipation notes, bond anticipation notes, certificates of
indebtedness, demand notes and construction loan notes.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
REPURCHASE AGREEMENTS--Agreements by which a Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. A Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement. A
Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if a Fund realizes a loss on the sale of
the collateral. A Fund will enter into repurchase agreements only with financial
institutions deemed to present minimal risk of bankruptcy during the term of the
agreement based on established guidelines. Repurchase agreements are considered
loans under the 1940 Act.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date, and no interest
accrues to a Fund before settlement. These securities are subject to market
fluctuation due to changes, real or anticipated, in market interest rates and
the public's perception of the creditworthiness of the issuer, and will have the
effect of leveraging the Fund's assets. Purchasing securities on a forward
commitment or when-issued basis when a Fund is fully or almost fully invested
may result in greater potential fluctuation in the value of a Fund's net asset
value per share. The purchasing Fund will establish one or more segregated
accounts with the Custodian, and will maintain liquid, high-grade assets in an
amount at least equal in value to the Fund's commitments to purchase when-issued
securities.
 
SECURITIES LENDING--In order to generate additional income, each Fund may lend
the securities in which it is invested, pursuant to agreements requiring that
the loan be continuously secured by cash, securities of the U.S. Government or
its agencies or any combination of cash and such securities as collateral equal
to 100% of the market value at all times of the loaned securities. The lending
Fund will continue to receive interest on the loaned securities while
simultaneously earning interest on the investment of cash collateral. Collateral
is marked to market daily to provide a level of collateral at least equal to the
value of the loaned securities. There may be risks of delay in receiving
additional collateral or risks of delay in recovery of the securities or even
loss of rights in the collateral should the borrower of the securities fail
financially.
<PAGE>   17
 
 17
 
TAX-EXEMPT COMMERCIAL PAPER-- Commercial paper, which is commercial paper issued
by governments and political sub-divisions.
 
SECURITIES SUBJECT TO A PUT FEATURE--A "put" feature permits a Fund to sell a
security at a fixed price prior to maturity. The underlying securities subject
to a put may be sold at any time at the market rates. However, unless the put
was an integral part of the security as originally issued, it may not be
marketable or assignable. Generally, a premium is paid for a put feature or a
put feature is purchased separately which results in a lower yield than would
otherwise be available for the same securities.
 
TIME DEPOSITS--Non-negotiable receipts issued by U.S. or foreign banks in
exchange for the deposit of funds. Like certificates of deposit, they earn a
specified rate of interest over a definite period of time; however, they cannot
be traded in the secondary market. Time deposits with a withdrawal penalty are
considered to be illiquid securities.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the Federal book-entry
systems.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates or
receipts. The custodian arranges for the issuances of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR's, TIGR's and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS -- Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.
 
RESTRAINTS ON INVESTMENTS BY MONEY MARKET FUNDS
 
Investments by the Funds are subject to limitations imposed under regulations
adopted by the SEC.
 
These regulations generally require money market funds to acquire only U.S.
dollar denominated obligations maturing in 397 days or less and to maintain a
dollar-weighted average portfolio maturity of 90 days or less. In addition, the
Funds
<PAGE>   18
 
 18
 
may acquire only obligations that present minimal credit risks and that are
"eligible securities," which means they are (i) rated, at the time of
investment, by at least two nationally recognized statistical rating
organizations (one if it is the only organization rating such obligation) in the
highest short-term rating category or, if unrated, determined to be of
comparable quality (a "first tier security"), or (ii) rated according to the
foregoing criteria in the second highest short-term rating category or, if
unrated, determined to be of comparable quality ("second tier security"). A
security is not considered to be unrated if its issuer has outstanding
obligations of comparable priority and security that have a short-term-rating.
In determining whether obligations are eligible securities, the rating of the
issuer's commercial paper, if any, is used for the above tests. Investments by
the Money Market Fund in second tier securities are subject to the further
constraints that (i) no more than 5% of the Fund's assets may be invested in
such securities in the aggregate, and (ii) any investment in such securities of
one issuer is limited to the greater of 1% of the Fund's total assets or $1
million. In addition, the Fund may invest up to 25% of its total assets in first
tier securities of a single issuer for three business days.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Institutional Class shares of the GOVERNMENT SECURITIES FUND, INTERMEDIATE-TERM
BOND FUND and CONVERTIBLE SECURITIES FUND (each a "Fund"). This summary is
qualified in its entirety by reference to the more detailed information provided
elsewhere in the Prospectus and in the Statement of Additional Information.
 
WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?  THE INTERMEDIATE-TERM BOND FUND
seeks to provide total return. THE GOVERNMENT SECURITIES FUND seeks to achieve
total return consistent with the preservation of capital by investing in a
diversified portfolio of obligations issued or guaranteed by the U.S. government
or its agencies or instrumentalities. THE CONVERTIBLE SECURITIES FUND seeks a
high level of current income and capital appreciation by investing in
convertible securities. See "Investment Objectives."
 
WHAT ARE THE FUNDS' PERMITTED INVESTMENTS?  THE INTERMEDIATE-TERM BOND FUND
invests primarily in debt instruments. THE GOVERNMENT SECURITIES FUND invests
primarily in debt obligations issued or guaranteed by the U.S. government or its
agencies or instrumentalities, including mortgage-backed securities issued or
guaranteed by U.S. government agencies. THE CONVERTIBLE SECURITIES FUND invests
primarily in convertible securities, including bonds, debentures, notes, and
preferred stocks convertible into common stock. See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUND?  The investment
policies of each Fund entail certain risks and considerations of which an
investor should be aware. The market value of a Fund's fixed income investments
will change in response to interest rate changes and other factors. During
periods of falling interest rates, the value of outstanding fixed income
securities generally rise. Conversely, during periods of rising interest rates,
the values of such securities generally decline. The Convertible Securities Fund
may invest up to 35% of its assets in convertible bonds rated lower than Baa by
Moody's Investors Service, Inc. ("Moody's") or BBB by Standard & Poor's
Corporation ("S&P") and as low as Caa by Moody's or CCC by S&P, which are
lower-quality, higher-yielding, high-risk debt securities. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by U.S. Government, its agencies or
instrumentalities of the securities in which any Fund invests guarantees only
the payment of principal and interest on the guaranteed security and does not
guarantee the yield or value of the security or yield or value of shares of that
Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE SUBADVISOR?  Bank of Tokyo-Mitsubishi Trust Company serves as the
SubAdvisor to the Government Securities and Convertible Securities Funds. See
"The SubAdvisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Institutional and Cash Sweep Class shares of the Trust and for the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment in the Fund's Institutional Class is $2,000. A
purchase order will be effective if the Distributor receives an order prior to
4:00 p.m., Eastern time and the Custodian receives Federal funds before the
close of business on the next Business Day. The purchase price is the net asset
value next determined after a purchase order is received and accepted by the
Trust. Redemption orders must be placed prior to 4:00 p.m., Eastern time on any
Business Day for the order to be accepted that day. See "Purchase and Redemption
of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of each Fund is distributed in the form of monthly
dividends to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF A FUND AND SHOULD NOT
BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES MAY
BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist the
investor in understanding the various costs and expenses that may be directly or
indirectly borne by investors in the Institutional Class shares of the Funds.
Financial institutions that are the record owner of shares for the account of
their customers may impose separate fees for account services to their
customers. The Trust also offers Investment Class shares of the Funds, which are
subject to the same expenses, except there are distribution and sales charges.

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes)
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Institutional Class shares of the Trust's Government Securities,
Intermediate-Term Bond and Convertible Securities Funds (each a "Fund").
Information regarding the Trust's other funds is contained in separate
prospectuses that may be obtained from the Trust's Distributor, SEI Financial
Services Company, 680 East Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVES
 
THE INTERMEDIATE-TERM BOND FUND seeks to provide total return.
 
THE GOVERNMENT SECURITIES FUND seeks to achieve total return consistent with the
preservation of capital by investing in a diversified portfolio of obligations
issued or guaranteed by the U.S. government or its agencies or
instrumentalities.
 
THE CONVERTIBLE SECURITIES FUND seeks a high level of current income and capital
appreciation by investing in convertible securities.
 
There can be no assurance that a Fund will meet its investment objective.
 
INVESTMENT POLICIES
 
INTERMEDIATE-TERM BOND FUND
 
Under normal market conditions, at least 65% of the Intermediate-Term Bond
Fund's assets will be invested in debt instruments. Such debt instruments shall
include corporate bonds and debentures rated AAA, AA, A or BBB by Standard &
Poor's Corporation ("S&P") or Aaa, Aa, A or Baa by Moody's Investors Service
("Moody's") or determined by the Advisor to be of comparable quality at the time
of purchase; Yankee Bonds and EuroDollar instruments; obligations issued by the
U.S. Government and its agencies and instrumentalities (such as Government
National Mortgage Association ("GNMA") securities); mortgage-backed securities
including privately issued mortgage-backed securities; readily-marketable
asset-backed securities; securities issued or guaranteed by foreign governments,
their political subdivisions, agencies or instrumentalities; and obligations of
supranational entities such as the World Bank and the Asian Development Bank.
The remainder of the Fund's assets may be invested in money market instruments
and in cash. The dollar-weighted average portfolio maturity of the Fund will be
from three to ten years.
 
The portfolio turnover rate for the Intermediate-Term Bond Fund for the fiscal
year ended January 31, 1996 was 147%. This rate of portfolio turnover may result
in higher brokerage execution costs and higher levels of capital gains.
 
GOVERNMENT SECURITIES FUND
 
Under normal market conditions, the Government Securities Fund will invest at
least 80% of its assets in obligations issued or guaranteed by the U.S.
government or its agencies or instrumentalities, including mortgage-backed
securities issued or guaranteed by U.S. government agencies such as GNMA, the
Federal National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage
Corporation ("FHLMC"), and repurchase agreements backed by such securities. The
Fund may invest any remaining assets in corporate bonds that carry a rating of
Baa or better by Moody's or BBB or better by S&P, or that are deemed by the
SubAdvisor to be of comparable quality; Yankee Bonds, including sovereign,
supranational and Canadian bonds; shares of other investment companies with
similar investment objectives;
<PAGE>   25
 
 6
 
commercial paper; money market funds; privately issued mortgage-backed and other
readily-marketable asset-backed securities; and money market instruments and
cash.
 
The SubAdvisor will seek to enhance the yield of the Fund by taking advantage of
yield disparities or other factors that occur in the government securities and
money markets. The Fund may dispose of any security prior to its maturity if
such disposition and reinvestment of the proceeds are expected to enhance its
yield consistent with the SubAdvisor's judgment as to a desirable maturity
structure or if such disposition is believed to be advisable due to other
circumstances or considerations. The Fund will seek to achieve capital gains by
taking advantage of price appreciation caused by interest rate and credit
quality changes.
 
The Fund may invest in futures and options on futures for the purpose of
achieving the Fund's objectives and for adjusting portfolio duration. The Fund
may invest in futures and related options based on any type of security or index
traded on U.S. or foreign exchanges or over the counter, as long as the
underlying security, or securities represented by an index, are permitted
investments of the Fund. The Fund may enter into futures contracts and options
on futures only to the extent that obligations under such contracts or
transactions represent not more than 10% of the Fund's assets.
 
The portfolio turnover rate for the Government Securities Fund for the fiscal
year ended January 31, 1996 was 239%. This rate of portfolio turnover may result
in higher brokerage execution costs and higher levels of capital gains.
 
CONVERTIBLE SECURITIES FUND
 
Under normal market conditions, at least 65% of the Convertible Securities
Fund's assets will be invested in convertible securities consisting of bonds,
debentures, notes and preferred stocks convertible into common stock. In
general, a convertible security is a fixed-income security, such as a bond
(which typically pays a fixed annual rate of interest) or preferred stock (which
typically pays a fixed dividend), that may be converted at a stated price within
a specified period of time into a specified number of shares of common stock of
the issuing company or of a different company. A convertible security may be
subject to redemption by the issuer, but only after a particular date and under
certain circumstances (including a specified price) established upon issue. If a
convertible security held by the Fund is called for redemption, the Fund could
be required to tender it for redemption, convert it into the underlying common
stock, or sell it to a third party. Common stock received upon conversion will
be sold when, in the opinion of the SubAdvisor, it is advisable to do so.
 
Because of its conversion feature, the market value of convertible preferred
stock tends to move together with the market value of the underlying common
stock. As a result, the Fund's selection of convertible securities is based, to
a great extent, on the potential for capital appreciation that may exist in the
underlying common stocks. The value of convertible securities is also affected
by prevailing interest rates, the credit quality of the issuer, and any call
provisions. Investments in convertible securities generally entail less
volatility than investments in the common stocks of the same issuers.
Nevertheless, it is the fixed income component of these securities that is often
deemed by the ratings agencies to be high risk or speculative. The Fund may
invest less than 35% of its assets in convertible bonds rated lower than Baa by
Moody's or BBB by S&P and as low as Caa by Moody's or CCC by S&P, which are
lower-quality, higher-yielding, high-risk debt securities (commonly known as
"junk bonds"). The Fund may also invest in unrated convertible securities which,
in the SubAdvisor's opinion, are of comparable quality to such rated securities.
See "Risk Factors."
 
The Fund may invest any remaining assets in common stocks; securities issued or
guaranteed by the U.S. government or its agencies or instrumentalities;
corporate bonds rated Baa or better by Moody's or BBB by S&P or better
<PAGE>   26

(investment grade bonds); shares of other investment companies with similar
investment objectives; high grade commercial paper; money market funds; money
market instruments and cash; floating and variable rate notes; repurchase
agreements; dollar-denominated securities of foreign issuers; and Standard and
Poor's Depository Receipts ("SPDRs").
 
GENERAL INVESTMENT POLICIES
 
Mortgage-backed securities purchased by the Funds will be issued or guaranteed
as to payment of principal and interest by the U.S. government or its agencies
or instrumentalities or, if issued by private issuers, rated in one of the two
highest rating categories by a nationally recognized rating agency. The
principal governmental issuers or guarantors of mortgage-backed securities are
GNMA, FNMA, and FHLMC. Obligations of GNMA are backed by the full faith and
credit of the United States Government, while obligations of FNMA and FHLMC are
supported by the credit of the respective agency only. The Funds may purchase
mortgage-backed securities that are backed or collateralized by fixed,
adjustable or floating rate mortgages.
 
For temporary defensive purposes during periods when the Advisor or SubAdvisor
determines that market conditions warrant, each Fund may invest up to 100% of
its assets in money market instruments consisting of securities issued or
guaranteed by the U.S. government, its agencies or instrumentalities, repurchase
agreements, receipts (including TR's, TIGR's and CATS), money market funds,
certificates of deposit, time deposits, bank master notes and bankers'
acceptances issued by banks having net assets of at least $1 billion as of the
end of their most recent fiscal year, commercial paper rated at least A-1 by S&P
or P-1 by Moody's, and in cash. A Fund will not be pursuing its investment
objective to the extent that a substantial portion of its assets are invested in
money market securities.
 
In the event that a security owned by a Fund is downgraded below the stated
ratings categories, the Advisor or SubAdvisor will take appropriate action with
regard to the security.
 
Each Fund will restrict its investment in illiquid securities to 15% of its net
assets.
 
Each Fund may engage in securities lending and will limit such practice to
33 1/3% of total assets.
 
Each Fund may purchase securities which have not been registered under the
Securities Act of 1933 (Rule 144A Securities).
 
Each Fund may purchase securities on a forward commitment or when-issued basis
where such purchases are for investment and not for leveraging purposes;
however, the Fund may sell these securities before the settlement date if it is
deemed advisable. No additional forward commitments will be made if more than
20% of a Fund's net assets would be so committed.
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
Each Fund's shares will fluctuate in value with the value of the underlying
securities in its portfolio. Because of their fixed income features, however,
convertible securities are expected to fluctuate in value to a lesser degree
than the common stock into which they are convertible. Changes in the value of a
Fund's portfolio securities will not affect cash income received from ownership
of such securities, but will affect the Fund's net asset value.
 
Mortgage-backed securities that are not issued or guaranteed by the U.S.
government or its agencies or instrumentalities, including securities nominally
issued by a government entity (such as the Resolution Trust Corporation), are
not obligations of a governmental entity, and thus may bear a greater risk of
nonpayment. The timely payment of principal and interest normally is supported,
at least partially, by various forms of insurance or guarantees. There can be no
assurance, however, that such credit enhancements will support fully the payment
of principal and interest on such obligations.
<PAGE>   27
 
 8
 
Securities rated BBB by S&P or Baa by Moody's are deemed by these rating
services to have some speculative characteristics and adverse economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than is the case with higher grade
bonds.
 
Each Fund may hold dollar-denominated securities of foreign issuers which may
bear greater investment risks than those of U.S. domestic issuers. Such risks
include political and economic instability, expropriation of foreign deposits
and other restrictions which may adversely affect the payment of principal, and
interest on such securities. See "Description of Permitted Investments."
 
RISKS ASSOCIATED WITH CONVERTIBLE SECURITIES
 
Investments in lower-rated debt securities (i.e., securities rated lower than
BBB by S&P or Baa by Moody's), in which the Convertible Securities Fund may
invest, bear certain risks, including the risk that such securities may be
thinly traded, which can adversely affect the price at which these securities
can be sold and can result in high transaction costs. Market quotations may not
be available, and therefore, judgment plays a greater role in valuing
lower-rated debt securities than securities for which more extensive quotations
and last sale information are available. Adverse publicity and changing investor
perceptions may affect the ability of outside pricing services to value
lower-rated debt securities, and the Convertible Securities Fund's ability to
dispose of these securities.
 
The market price of lower-rated debt securities may decline significantly in
periods of general economic difficulty which may follow periods of rising
interest rates. During an economic downturn or a prolonged period of rising
interest rates, the ability of issuers of lower-rated debt to meet their payment
obligations on these securities may be impaired.
 
The Convertible Securities Fund may invest in securities which are rated as low
as 'Caa' by Moody's or 'CCC' by S&P. Securities rated 'Caa' by Moody's are of
poor standing and may be in default or may present elements of danger with
respect to principal or interest. Debt rated 'CCC' by S&P is regarded as having
speculative characteristics with respect to capacity to pay interest and repay
principal. In the event of adverse business, financial, and economic conditions,
debt rated 'CCC' is not likely to have the capacity to repay principal.
 
INVESTMENT LIMITATIONS
 
Each Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the U.S. government or its agencies or instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of a Fund would be invested in the securities of such issuer. This
restriction applies to 75% of a Fund's assets.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies or instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objectives and policies, (b) enter into
repurchase agreements, and (c) engage in securities lending as described in this
Prospectus and in the Statement of Additional Information.
<PAGE>   28

The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Funds. Fundamental policies cannot be changed with
respect to a Fund without the consent of the holders of a majority of the Fund's
outstanding shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of the Intermediate-Term Bond Fund and
continuously reviews, supervises and administers each Fund's investment program.
The Advisor discharges its responsibilities subject to the supervision of, and
policies established by, the Trustees of the Trust. The Trust's shares are not
sponsored, endorsed or guaranteed by, and do not constitute obligations or
deposits of, the Advisor and are not guaranteed by the FDIC or any other
governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .50% of the average daily net assets of the Government
Securities and Intermediate-Term Bond Funds and .60% of the average daily net
assets of the Convertible Securities Fund. The Advisor may from time to time
waive all or a portion of its fee in order to limit the operating expenses of a
Fund. Any such waiver is voluntary and may be terminated at any time in the
Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, predecessor of the
Advisor, was paid an advisory fee of .50%, .50% and .60% of the average daily
net assets of the Intermediate-Term Bond Fund, Government Securities Fund and
Convertible Securities Fund, respectively.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of each Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd..
 
James V. Atkinson has served as team leader of the Intermediate-Term Bond Fund
since 1991. Mr. Atkinson is a Vice President of the Advisor and has been with
the Advisor and its predecessor, Union Bank, since 1991. Mr. Atkinson was a
portfolio manager at The Boston Company from 1988 to 1990.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE SUBADVISOR
 
The Advisor and Bank of Tokyo-Mitsubishi Trust Company (the "SubAdvisor") have
entered into an investment subadvisory agreement relating to the Government
Securities and Convertible Securities Funds (the "Investment SubAdvisory
Agreement"). Under the Investment SubAdvisory Agreement, the SubAdvisor makes
the day-to-day investment decisions for the assets of the Government Securities
and Convertible Securities Funds, subject to the supervision of, and policies

established by, the Advisor and the Trustees of the Trust.
 
Bank of Tokyo-Mitsubishi Trust Company, headquartered at 1251 Avenue of the
Americas, New York, New York 10116, and with offices at 100 Broadway, New York,
New York 10005, operates as a wholly-owned subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd. The SubAdvisor was formed by the combination on April 1,
1996, of Bank of Tokyo Trust Company, a wholly-owned subsidiary of The Bank of
Tokyo, Ltd., and Mitsubishi Bank Trust Company of New York, a wholly-owned
subsidiary of The Mitsubishi Bank, Ltd. Bank of Tokyo Trust Company was the
surviving entity, and changed its name to Bank of Tokyo-Mitsubishi Trust
Company. Prior to the combination, subadvisory services were provided by Bank of
Tokyo Trust Company. Bank of Tokyo Trust Company was established in 1955, and
has provided trust services since that time and management services since 1965.
 
The SubAdvisor serves as portfolio manager to bank common funds, employee
benefit funds and personal trust accounts, managing assets in money market,
equity and fixed income portfolios. As of April 1, 1996, Bank of
Tokyo-Mitsubishi Trust Company managed $750 million in individual portfolios and
collective funds. In addition, the SubAdvisor also serves as SubAdvisor to the
Trust's Emerging Growth and Blue Chip Growth Funds.
 
The SubAdvisor is entitled to a fee, which is calculated daily and paid monthly
out of the Advisor's fee, at an annual rate of .20% of the average daily net
assets of the Government Securities Fund and .30% of the average daily net
assets of the Convertible Securities Fund. For the fiscal year ended January 31,
1996, Bank of Tokyo Trust Company, predecessor of the SubAdvisor, received .20%
and .30% of the average daily net assets of the Government Securities Fund and
the Convertible Securities Fund, respectively.
 
Stephen W. Blocklin has served as portfolio manager of the Government Securities
Fund since its inception. Mr. Blocklin has been a Vice President with the
SubAdvisor and its predecessor, Bank of Tokyo Trust Company, since December,
1993. From September, 1988 to December, 1993, he served as a senior fixed income
fund manager in the institutional investment management group at First Fidelity
Bancorporation.
 
The day-to-day management of the Convertible Securities Fund's investments is
the responsibility of a team of investment professionals.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of the average daily net assets of the Trust
up to $1 billion, .12% of the average daily net assets between $1 billion and $2
billion and .10% of the average daily net assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of a Fund's Institutional Class
shares. Any such waiver is voluntary and may be terminated at any time in the
Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional and Cash
Sweep Class shares of the Trust and for the Investment Class shares of the
Convertible Securities, Government Securities, Emerging Growth, Blue Chip Growth
and International Equity Funds. Compensation for these services is paid under
the Administration Agreement.

DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the outstanding shares of
the Trust upon not more than 60 days' written notice by either party, or upon
assignment by the Distributor. Investment Class shares of a Fund, which are
offered by a separate prospectus, may bear the costs of their distribution
expenses and, a sales charge is imposed on the sale of Investment Class shares
of the Funds. It is possible that an institution may offer different classes of
shares to its customers and thus receive different compensation with respect to
different classes of shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Funds may be made on days on which
both the New York Stock Exchange and Federal Reserve wire system are open for
business ("Business Days"). The minimum initial investment in a Fund is $2,000;
however, the minimum investment may be waived at the Distributor's discretion.
 
Purchase orders will be effective as of the day they are received by the
Distributor if the Distributor receives the order before 4:00 p.m., Eastern time
and the Custodian receives Federal funds before the close of business on the
next Business Day.
 
The purchase price of shares of a Fund is the net asset value next determined
after a purchase order is received and accepted by the Trust. The net asset
value per share of a Fund is determined by dividing the total market value of a
Fund's investments and other assets, less any liabilities, by the total number
of outstanding shares of a Fund. Net asset value per share is determined daily
as of 4:00 p.m., Eastern time, on any Business Day. Purchases will be made in
full and fractional shares of a Fund calculated to three decimal places. The
Trust reserves the right to reject a purchase order when the Distributor
determines that it is not in the best interest of the Trust and/or its
Shareholders to accept such order.
 
Shares of the Funds are offered only to residents of states in which the shares
are eligible for purchase.
 
Shareholders who desire to redeem shares of a Fund must place their redemption
orders prior to 4:00 p.m., Eastern time, on any Business Day for the order to be
accepted on that Business Day. The redemption price is the net asset value of a
Fund next determined after receipt by the Distributor of the redemption order.
Payment on redemption will be made as promptly as possible and, in any event,
within seven calendar days after the redemption order is received.
 
Neither the Trust's Transfer Agent nor the Trust will be responsible for any
loss, liability, cost, or expense for acting upon wire instructions or upon
telephone instructions that it reasonably believes are genuine. The Trust and
its transfer agent will each employ reasonable procedures to confirm that
telephone instructions are genuine. Such procedures may include taping of
telephone conversations. If market conditions are extraordinarily active or
other extraordinary circumstances exist, and you experience difficulties placing
redemption orders by telephone, you may wish to consider placing your order by
other means.
 
PERFORMANCE
 
From time to time, the Funds may advertise yield and total return. These figures
will be based on historical earnings and are not intended to indicate future
performance. The yield of a Fund refers to the annualized income generated by an
investment in the Fund over a specified 30-day period. The yield is calculated
by assuming that the same amount of income generated by the investment during
the period is generated in each 30-day period over one year and is shown as a
percentage of the investment.
<PAGE>   31
 
 12
 
The total return of a Fund refers to the average compounded rate of return to a
hypothetical investment, for designated time periods (including, but not limited
to, the period from which the Fund commenced operations through the specified
date), assuming that the entire investment is redeemed at the end of each period
and assuming the reinvestment of all dividend and capital gain distributions.
The total return of a Fund may also be quoted as a dollar amount or on an
aggregate basis, an actual basis, without inclusion of any sales charge, or with
a reduced sales charge in advertisements distributed to investors entitled to a
reduced sales charge.
 
A Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial, or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local income tax treatment of a Fund or
its Shareholders. In addition, state and local income tax consequences of an
investment in a Fund may differ from the federal income tax consequences
described below. Accordingly, Shareholders are urged to consult their tax
advisers regarding specific questions as to federal, state, and local income
taxes. Additional information concerning taxes is set forth in the Statement of
Additional Information.
 
TAX STATUS OF THE FUNDS:
 
Each Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. Each Fund intends to continue to
qualify for the special tax treatment afforded regulated investment companies by
the Internal Revenue Code of 1986, as amended (the "Code"), so as to be relieved
of federal income tax on that part of its net investment company taxable income
and net capital gain (the excess of net long-term capital gain over net
short-term capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
A Fund will distribute all of its net investment income (including net
short-term capital gain) to Shareholders. Dividends from the Fund's net
investment company taxable income are taxable to Shareholders as ordinary income
(whether received in cash or in additional shares) to the extent of the Fund's
earnings and profits. Any net capital gains will be distributed at least
annually
<PAGE>   32
 
 13
 
and will be taxed to Shareholders as long-term capital gains, regardless of how
long the Shareholder has held shares and regardless of whether the distributions
are received in cash or in additional shares. Dividends paid by a Fund to
corporate Shareholders will qualify for the dividends-received deduction to the
extent derived from dividends received by the Fund from domestic corporations. A
portion of such dividends may be subject to the alternative minimum tax. Each
Fund will provide annual reports to Shareholders of the federal income tax
status of all distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments, a
Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because each Fund distributes
all of its net investment income to Shareholders, a Fund may have to sell
portfolio securities to distribute such imputed income, which may occur at a
time when the Advisor or SubAdvisor would not have chosen to sell such
securities and which may result in a taxable gain or loss.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level when received directly by a Fund, and may be
exempt, depending on the state, when received by a Shareholder as income
dividends from a Fund provided certain state-specific conditions are satisfied.
Interest realized on repurchase agreements collateralized by U.S. government
obligations normally is not exempt from state tax. Each Fund will inform
Shareholders annually of the percentage of income and distributions derived from
direct U.S. Treasury obligations. Shareholders should consult their tax advisors
to determine whether any portion of the income dividends received from a Fund is
considered tax exempt in their particular state.
 
Income derived by a Fund from obligations of foreign issuers may be subject to
foreign withholding taxes. A Fund will not be able to elect to treat
Shareholders as having paid their proportionate share of such taxes.
 
Dividends declared by a Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared if paid by the Fund any time during the following January.
 
The Funds intend to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Each sale, exchange, or redemption of Fund shares is a taxable event to the
Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate portfolios of shares and different classes of each fund. In
addition to the Funds, the Trust consists of the following funds: Treasury Money
Market Fund, Money Market Fund, California Tax-Free Money Market Fund, Growth
Equity Fund, Value Momentum Fund, Balanced Fund, California Intermediate
Tax-Free Bond Fund, Blue Chip Growth Fund, Limited Maturity Government Fund,
Emerging Growth Fund and International Equity Fund. All consideration received
by the Trust for shares of any fund and all assets of such fund belong to that
fund and would be subject to liabilities related thereto. The Trust reserves the
right to create and issue shares of additional funds.
 
The Trust pays its expenses, including fees of its service providers, audit and
legal expenses, expenses of preparing prospectuses, proxy solicitation material
and reports to shareholders, costs of custodial services and registering the
shares under Federal and State securities laws, pricing, insurance expenses,
litigation and other
<PAGE>   33
 
 14
 
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses. Please refer to "Financial Highlights" in this prospectus
for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to that fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings of shareholders, but approval will be sought for certain changes
in the operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate
assistance and information to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania,
19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of
the Fund is distributed in the form of monthly dividends to Shareholders of
record. Currently, capital gains of a Fund, if any, will be distributed at least
annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares unless the Shareholder has elected to take
such payment in cash. Shareholders may change their election by providing
written notice to the Administrator at least 15 days prior to the distribution.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The amount of dividends payable on Institutional Class shares will typically be
higher than the dividends payable on the Investment Class shares because of the
distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank, N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the Trust. The
Custodian holds cash, securities and other assets of the Trust as required by
the Investment Company Act of 1940, as amended.

DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Funds:
 
ASSET-BACKED SECURITIES (NON-MORTGAGE)--Instruments secured by company
receivables, truck and auto loans, leases, and credit card receivables. Such
securities are generally issued as pass-through certificates, which represent
undivided fractional ownership interests in the underlying pools of assets. Such
securities also may be debt instruments, which are also known as collateralized
obligations and are generally issued as the debt of a special purpose entity,
such as a trust, organized solely for purpose of owning such assets and issuing
such debt. The purchase of non-mortgage asset-backed securities raises risk
considerations peculiar to the financing of the instruments underlying such
securities. Asset-backed securities entail prepayment risk, which may vary
depending on the type of asset, but is generally less than the prepayment risk
associated with mortgage-backed securities.
 
CONVERTIBLE BONDS AND CONVERTIBLE PREFERRED STOCK--Convertible bonds are bonds
convertible into a set number of shares of another form of security (usually
common stock) at a prestated price. Convertible bonds have characteristics
similar to both fixed income and equity securities. Convertible preferred stock
is a class of capital stock that pays dividends at a specified rate and that has
preference over common stock in the payment of dividends and the liquidation of
assets. Convertible preferred stock is preferred stock exchangeable for a given
number of common stock shares, and has characteristics similar to both
fixed-income and equity securities. Because of the conversion feature, the
market value of convertible bonds and convertible preferred stock tends to move
together with the market value of the underlying stock. As a result, the Fund's
selection of convertible bonds and convertible preferred stock is based, to a
great extent, on the potential for capital appreciation that may exist in the
underlying stock. The value of convertible bonds and convertible preferred stock
is also affected by prevailing interest rates, the credit quality of the issuer
and any call provisions.
 
CORPORATE OR GOVERNMENT BONDS-- Interest-bearing or discounted corporate or
government securities that obligates the issuer to pay the bondholder a
specified sum of money, usually at specific intervals, and to repay the
principal amount of the loan at maturity. Bonds rated Baa or better by Moody's
or BBB or better by S&P, are considered investment grade quality.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities, (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
FUTURES AND OPTIONS ON FUTURES--Some futures strategies, including selling
futures, buying puts and writing calls, reduce a Fund's exposure to price
fluctuations. Other strategies, including buying futures, writing puts and
buying calls, tend to increase market exposure. Futures and options may be
combined with each other in order to adjust the risk and return characteristics
of the overall portfolio.
 
Options and futures can be volatile instruments, and involve certain risks that
if applied at an inappropriate time, could negatively impact the Fund's return.
 
LOWER-RATED, HIGHER-YIELDING, HIGH-RISK DEBT SECURITIES--High-yield, high-risk
securities consist of securities rated Ba or lower by Moody's or BB or lower by
S&P. Lower-rated debt securities are considered speculative and involve greater
risk of loss than investment grade debt securities, and are more sensitive to
changes
<PAGE>   35
 
 16
 
in the issuer's capacity to pay. For a description of the debt securities
ratings, see the "Appendix."
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term, debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial paper; and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and
broker-dealers.
 
MORTGAGE-BACKED SECURITIES--Mortgage-backed securities are generally issued or
guaranteed by U.S. government agencies such as GNMA, FNMA, or FHLMC. GNMA
mortgage-backed certificates are mortgage-backed securities of the modified
pass-through type, which means that both interest and principal payments
(including prepayments) are passed through monthly to the holder of the
certificate. Each GNMA certificate evidences an interest in a specific pool of
mortgage loans insured by the Federal Housing Administration or the Farmers Home
Administration or guaranteed by the Veterans Administration. FNMA, a federally-
chartered and stockholder-owned corporation, issues pass-through certificates
which are guaranteed as to payment of principal and interest by FNMA. FHLMC, a
corporate instrumentality of the United States, issues participation
certificates which represent an interest in mortgages held in FHLMC's portfolio.
FHLMC guarantees the timely payment of interest and the ultimate collection of
principal. Securities issued or guaranteed by FNMA and FHLMC are not backed by
the full faith and credit of the United States. There can be no assurance that
the U.S. government would provide financial support to FNMA or FHLMC if
necessary in the future.
 
Adjustable rate mortgage securities ("ARMs") are pass-through certificates
representing ownership interests in a pool of adjustable rate mortgages and the
resulting cash flow from those mortgages. Unlike conventional debt securities,
which provide for periodic (usually semi-annually) payments of interest and
payments of principal at maturity or on specified call dates, ARMs provide for
monthly payments based on a pro rata share of both periodic interest and
principal payments and prepayments of principal on the underlying mortgage pool
(less GNMA's, FNMA's, or FHLMC's fees and any applicable loan servicing fees).
 
Collateralized mortgage obligations ("CMOs") are bonds generally issued by
single purpose, stand-alone finance subsidiaries or trusts established by
financial institutions, government agencies, investment banks, or other similar
institutions, and collateralized by pools of mortgage loans. Payments of
principal and interest on the collateral mortgages are used to pay debt service
on the CMO. In a CMO, a series of bonds or certificates is issued in multiple
classes. Each class of CMOs, often referred to as a "tranche," is issued at a
specific coupon rate and has a stated maturity or final distribution date. The
principal and interest payment on the underlying mortgages may be allocated
among the classes of CMOs in several ways. Typically, payments of principal,
including any prepayments, on the underlying mortgages would be applied to the
classes in the order of their respective stated maturities or final distribution
dates, so that no payment of principal will be made on CMOs of a class until all
CMOs of other classes having earlier stated maturities or final distribution
dates have been paid in full.
 
One or more classes of CMOs may have coupon rates that reset periodically based
on an index, such as the London Interbank Offered Rate ("LIBOR"). The Government
Securities Fund and Intermediate-Term Bond Fund may purchase fixed, adjustable,
or "floating" rate CMOs that are collateralized by fixed rate or adjustable rate
mortgages that are guaranteed as to payment of principal and interest by an
agency or
<PAGE>   36
 
 17
 
instrumentality of the U.S. government or are directly guaranteed as to payment
of principal and interest by the issuer, which guarantee is collateralized by
U.S. government securities; or are collateralized by privately issued fixed rate
or adjustable rate mortgages.
 
Real Estate Mortgage Investment Conduits ("REMICs") are private entities formed
for the purpose of holding a fixed pool of mortgages secured by an interest in
real property. REMICs are similar to CMOs in that they issue multiple classes of
securities.
 
REPURCHASE AGREEMENTS--Agreements by which a Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement. A
Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if the Fund realizes a loss on the sale
of the collateral. A Fund will enter into repurchase agreements only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based on established guidelines. Repurchase agreements are
considered loans under the 1940 Act.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date, and no interest
accrues to a Fund before settlement. These securities are subject to market
fluctuation due to changes, real or anticipated, in market interest rates and
the public's perception of the creditworthiness of the issuer and will have the
effect of leveraging the Fund's assets. Purchasing securities on a forward
commitment or when-issued basis when a Fund is fully or almost fully invested
may result in greater potential fluctuation in the value of a Fund's net asset
value per share. The purchasing Fund will establish one or more segregated
accounts with the Custodian, and will maintain liquid, high-grade assets in an
amount at least equal in value to the Fund's commitments to purchase when-issued
securities.
 
SECURITIES LENDING--In order to generate additional income, each Fund may lend
the securities in which it is invested, pursuant to agreements requiring that
the loan be continuously secured by cash, securities of the U.S. Government or
its agencies or any combination of cash and such securities as collateral equal
to 100% of the market value at all times of the loaned securities. The lending
Fund will continue to receive interest on the loaned securities while
simultaneously earning interest on the investment of cash collateral. Collateral
is marked to market daily to provide a level of collateral at least equal to the
value of the loaned securities. There may be risks of delay in receiving
additional collateral or risks of delay in recovery of the securities or even
loss of rights in the collateral should the borrower of the securities fail
financially.
 
STANDARD & POOR'S DEPOSITARY RECEIPTS ("SPDRs")--Interests in a unit investment
trust holding a portfolio of securities linked to the S&P 500 Index. SPDRs
closely track the underlying portfolio of securities, trade like a share of
common stock and pay periodic dividends proportionate to those paid by the
portfolio of stocks that constitutes the S&P 500 Index. For further information
regarding a Fund's investment in SPDRs, see the Statement of Additional
Information.
<PAGE>   37
 
 18
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes, and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS"), that are transferable through the Federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of such
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's"), "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than
interest-paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.
 
YANKEE BONDS--Dollar-denominated securities issued by foreign-domiciled issuers
that obligate the issuer to pay the bondholder a specified sum of money, usually
semiannually, and to repay the principal amount of the loan at maturity.
Sovereign bonds are bonds issued by the governments of foreign countries.
Supranational bonds are those issued by supranational entities, such as the
World Bank and the European Investment Bank. Canadian bonds are bonds issued by
Canadian provinces.
 
SECURITIES OF FOREIGN ISSUERS--Securities issued by non-U.S. issuers. There may
be certain risks connected with investing in foreign securities, including risks
of adverse political and economic developments (including possible governmental
seizure or nationalization of assets), the possible imposition of exchange
controls or other governmental restrictions, including less uniformity in
accounting and reporting requirements, the possibility that there will be less
information on such securities and their issuers available to the public, the
difficulty of obtaining or enforcing court judgments abroad, restrictions on
foreign investments in other jurisdictions, difficulties in effecting
repatriation of capital invested abroad, and difficulties in transaction
settlements and the effect of delay on shareholder equity. Foreign securities
may be subject to foreign taxes, which reduce yield, and may be less marketable
than comparable U.S. securities. A Fund may be affected favorably or unfavorably
by changes in the
<PAGE>   38
 
 19
 
exchange rates or exchange control regulations between foreign currencies and
the U.S. dollar. Changes in foreign currency exchange rates may also affect the
value of dividends and interest earned, gains and losses realized on the sale of
securities and net investment income and gains, if any, distributed to
shareholders by a Fund. See "Risk Factors."

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Institutional Class shares of the GROWTH EQUITY, VALUE MOMENTUM, BLUE CHIP
GROWTH, EMERGING GROWTH and BALANCED FUNDS, (each a "Fund"). This summary is
qualified in its entirety by reference to the more detailed information provided
elsewhere in the Prospectus and in the Statement of Additional Information.
 
WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?  THE BALANCED FUND seeks to provide
both capital appreciation and income. THE VALUE MOMENTUM FUND seeks long-term
capital growth with a secondary objective of income. THE BLUE CHIP GROWTH FUND
seeks long-term capital growth by investing in a diversified portfolio of common
stocks and other equity securities of seasoned, large capitalization companies.
THE GROWTH EQUITY FUND seeks long-term capital growth. THE EMERGING GROWTH FUND
seeks long-term growth of capital by investing in a diversified portfolio of
equity securities of small capitalization, emerging growth companies. See
"Investment Objectives."
 
WHAT ARE THE FUNDS' PERMITTED INVESTMENTS?  Each of the Funds may invest,
consistent with its investment objectives, in equity securities, including
common stocks and securities convertible into common stocks. Each Fund, except
the Emerging Growth Fund, may also invest, consistent with its investment
objective and investment policies, in debt securities. See "Investment
Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUNDS?  The investment
policies of each Fund entail certain risks and considerations of which an
investor should be aware. Each of the Funds may purchase common stocks and other
equity securities that are volatile and which may fluctuate in value more than
other types of investments. Values of fixed income securities and,
correspondingly, share prices of Funds invested in such securities, tend to vary
inversely with interest rates, and may be affected by other market and economic
factors as well. In addition, the securities of the emerging growth companies in
which the Emerging Growth Fund may invest may be less liquid, and subject to
more abrupt or erratic market movements, than securities of larger, more
established growth companies.
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE SUBADVISOR?  Bank of Tokyo-Mitsubishi Trust Company serves as the
SubAdvisor to the Emerging Growth and Blue Chip Growth Funds. See "The
SubAdvisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Institutional and Cash Sweep Class shares of the Trust and for the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment in the Trust is $2,000. A purchase order will be
effective if the Distributor receives an order prior to 4:00 p.m., Eastern time
and the Custodian receives Federal funds before the close of business on the
next Business Day. The purchase price is the net asset value next determined
after a purchase order is received and accepted by the Trust. Redemption orders
must be placed prior to 4:00 p.m., Eastern time on any Business Day for the
order to be accepted that day. See "Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of the Funds is distributed in the form of monthly
dividends to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF A FUND AND SHOULD NOT
BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES MAY
BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist the
investor in understanding the various costs and expenses that may be directly or
indirectly borne by investors in the Institutional Class shares of the Funds.
Financial institutions that are the record owner of shares for the account of
their customers may impose separate fees for account services to their
customers. The Trust also offers Investment Class shares of the Funds, which are
subject to the same expenses, except that Investment Class shares are subject to
sales charges and distribution expenses. Additional information may be found

which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Institutional Class shares of the Trust's Growth Equity, Value Momentum,
Blue Chip Growth, Emerging Growth and Balanced Funds (each a "Fund").
Information regarding the Trust's other funds is contained in separate
prospectuses that may be obtained from the Trust's Distributor, SEI Financial
Services Company, 680 East Swedesford Road, Wayne, Pennsylvania 19087-1658.

INVESTMENT POLICIES
 
BALANCED FUND
 
The Balanced Fund invests in a combination of equity, fixed-income, and money
market securities. Under normal market conditions, the Fund will invest between
50% and 70% of its total assets in equity securities, including common stocks,
warrants, and U.S. dollar denominated securities of foreign issuers, and both
preferred stock and debt securities convertible into common stocks. The Fund may
invest in a broad spectrum of common stocks with varying characteristics. All of
the common stocks in which the Fund invests (including foreign securities in the
form of American Depositary Receipts ("ADRs")) are traded on registered
exchanges or the over the counter market. Under normal market conditions, a
minimum of 25% of the Fund's total assets will be invested in senior fixed
income securities. Such securities consist of bonds, debentures, and similar
obligations or instruments which constitute a security and evidence
indebtedness. Corporate bonds and debentures will be rated AAA, AA, A, or BBB by
Standard & Poor's Corporation ("S&P") or Aaa, Aa, A, or Baa by Moody's Investors
Service ("Moody's") or as determined by the Advisor to be of comparable quality
at the time of purchase. The Fund may also invest in mortgage-backed securities
that are rated in one of the top two rating categories by Moody's or S&P, and
may invest in other asset-backed securities backed by company receivables, truck
and auto loans, leases, and credit card receivables.
 
The Fund may also buy and sell options, futures contracts and options on
futures. The Fund may enter into futures contracts and options on futures only
to the extent that obligations under such contracts or transactions, together
with options on securities represent not more than 25% of the Fund's assets. The
aggregate value of options on securities (long puts and calls) will not exceed
10% of the Fund's net assets at the time such options are purchased by the Fund.
 
The Fund may invest in securities issued or guaranteed by foreign governments,
their political
<PAGE>   45
 
 6
 
subdivisions, agencies or instrumentalities and obligations of supranational
entities such as the World Bank and the Asian Development Bank.
 
Money market instruments the Fund may invest in consist of: (i) commercial paper
rated at least A-1 by S&P or P-1 by Moody's at the time of investment, or, if
not rated, are determined by the Advisor to be of comparable quality; (ii)
obligations (certificates of deposit, time deposits, bank master notes, and
bankers' acceptances) of thrift institutions, savings and loans, U.S. commercial
banks (including foreign branches of such banks), and U.S. and foreign branches
of foreign banks, provided that such institutions (or, in the case of a branch,
the parent institution) have total assets of $1 billion or more as shown on
their last published financial statements at the time of investment; (iii)
short-term corporate obligations rated at least A by S&P or A by Moody's at the
time of investment, or, if not rated, determined by the Advisor to be of
comparable quality; (iv) general obligations issued by the U.S. Government and
backed by its full faith and credit, and obligations issued or guaranteed as to
principal and interest by agencies or instrumentalities of the U.S. Government
(e.g., obligations issued by Farmers Home Administration, Government National
Mortgage Association, Federal Farm Credit Bank and Federal Housing
Administration); (v) receipts, including TR's, TIGR's and CATS; (vi) repurchase
agreement involving such obligations; (vii) loan participations; (viii) money
market funds; and (ix) foreign commercial paper. The Fund may only purchase
interests in loan participations issued by a bank in the United States with
assets exceeding $1 billion and for which the underlying loan is issued by
borrowers in whose obligations the Fund may invest.
 
Certain of the obligations in which the Fund may invest may be variable or
floating rate instruments, may involve conditional or unconditional demand
features and may include variable amount master demand note.
 
The Fund may enter into forward commitments, or purchase securities on a
when-issued basis. The Fund is permitted to invest in when-issued securities
where such purchases are for investment and not for leveraging purposes;
however, the Fund may sell those securities before the settlement date if it is
deemed advisable. No additional forward commitments will be made if more than
20% of the Fund's net assets would be so committed.
 
VALUE MOMENTUM FUND
 
Under normal market conditions, at least 65% of the Value Momentum Fund's assets
will be invested in equity securities, including common stocks, warrants to
purchase common stock, debt securities and preferred stocks convertible into
common stocks, and ADRs.
 
The Fund invests primarily in securities which the Advisor believes to be
undervalued relative to the market and to the security's historic valuation.
Stocks are then screened for positive price or earnings momentum. Securities
purchased will generally have a medium to high market capitalization. A majority
of the securities in which the Fund invests will be dividend paying. All of the
common stocks in which the fund invests are traded on registered exchanges or
the over-the-counter market.
 
The remainder of the Fund's assets may be invested in covered call options on
equity securities, money market instruments consisting of securities issued or
guaranteed by the U.S. government or its agencies or instrumentalities, receipts
including TR's, TIGR's and CATS, money market funds, repurchase agreements,
certificates of deposit, time deposits, bank master notes and bankers'
acceptances issued by banks having net assets of at least $1 billion as of the
end of their most recent fiscal year, commercial paper rated at least A-1 by S&P
or P-1 by Moody's and in cash.
 
BLUE CHIP GROWTH FUND
 
Under normal market conditions, at least 65% of the Blue Chip Growth Fund's
assets will be invested in equity securities, including common stocks, warrants
to purchase common stocks, U.S.
<PAGE>   46
 
 7
 
dollar denominated equity securities of foreign issuers traded as ADRs,
preferred stocks convertible into common stocks, and units representing
combinations of the foregoing. The Fund primarily invests in equity securities
of seasoned, large capitalization companies. A seasoned company is a company
with a operating history of 3 years or more. A large capitalization company is a
company with capitalization in excess of $1.0 billion. The Fund will limit its
investment in foreign securities to 15% of its total assets. A majority of the
Fund's equity investments ordinarily will consist of dividend-paying securities.
 
The balance of the Fund's assets may be invested in money market instruments,
options, futures contracts and options on futures, Standard & Poor's Depositary
Receipts ("SPDRs"), shares of other investment companies with similar investment
objectives, investment grade bonds and bonds convertible into common stocks. The
aggregate value of options on securities (long puts and calls) will not exceed
10% of a Fund's net assets at the time such options are purchased by the Fund.
 
The Fund may enter into futures and options on futures only to the extent that
obligations under such contracts or transactions, together with options on
securities, represent not more than 25% of the Fund's assets. All of the common
stocks in which the Fund invests (including foreign securities, in the form of
ADRs but not including Rule 144A Securities) are traded on registered exchanges
or in the over the counter market.
 
GROWTH EQUITY FUND
 
Under normal market conditions, at least 65% of the Growth Equity Fund's assets
will be invested in equity securities consisting of common stocks, warrants to
purchase common stocks, U.S. dollar denominated equity securities of foreign
issuers, and debt securities and preferred stock convertible into common stocks.
 
The Fund may invest in covered call options on equity securities and money
market instruments consisting of securities issued or guaranteed by the U.S.
government or its agencies or instrumentalities, receipts, including TR's,
TIGR's and CATS, money market funds, repurchase agreements, certificates of
deposit, time deposits, bank master notes and bankers' acceptances issued by
banks having net assets of at least $1 billion as of the end of their most
recent fiscal year, commercial paper rated at least A-1 by S&P or P-1 by Moody's
and in cash. All of the common stocks in which the Fund invests (including
foreign securities in the form of ADRs) are traded on registered exchanges or
the over the counter market.
 
EMERGING GROWTH FUND
 
Under normal market conditions, the Emerging Growth Fund will invest at least
65% of its assets in equity securities (i.e., common stocks and convertible
preferred stocks) of small capitalization (i.e., companies with capitalization
between $50 million and $1 billion) with the potential for growth or which, in
the Advisor's opinion, have potential for above-average long-term capital
appreciation. An emerging growth company is one which, in the Advisor's
judgment, is in the developing stages of its life cycle and has demonstrated or
is expected to achieve rapid growth in earnings and/or revenues. Emerging growth
companies are characterized by opportunities for rapid growth rates and/or
dynamic business changes. Emerging growth companies, regardless of size, tend to
offer the potential for accelerated earnings or revenue growth because of new
products or technologies, new channels of distribution, revitalized management
or industry conditions, or similar opportunities. A company may or may not yet
be profitable at the time the Fund invests in its securities. Current income
will not be a criterion of investment selection, and any such income should be
considered incidental. Many of the securities in which the Fund invests will not
pay dividends.
 
The Fund may also invest in equity securities of companies in "special equity
situations," meaning companies experiencing unusual and possibly non-repetitive
developments, such as mergers; acquisitions; spin-offs; liquidations;
<PAGE>   47
 
 8
 
reorganizations; and new products, technology or management. Since a special
equity situation may involve a significant change from a company's past
experiences, the uncertainties in the appraisal of the future value of the
company's equity securities and the risk of a possible decline in the value of
the Fund's investments are significant.
 
The Fund may invest in U.S. dollar denominated equity securities of foreign
issuers traded as ADRs. All of the common stocks in which the Fund invests (with
the exception of Rule 144A Securities) are traded on registered exchanges or in
the over the counter market.
 
The balance of the Fund's assets may be invested in money market instruments.
The Fund may also invest in options, futures and options on futures, shares of
other investment companies with similar investment objectives, SPDRs and
convertible bonds. The Fund may enter into futures contracts and options on
futures to the extent that obligations under such contracts or transactions,
together with options on securities, represent not more than 25% of the Fund's
assets. The aggregate value of options on securities (long puts and calls) will
not exceed 10% of the Fund's net assets at the time such options are purchased
by the Fund.
 
The portfolio turnover rate for the Emerging Growth Fund for the fiscal year
ended January 31, 1996 was 131%. This rate of portfolio turnover may result in
higher brokerage execution costs and higher levels of capital gains.
 
GENERAL INVESTMENT POLICIES
 
For temporary defensive purposes during periods when the Advisor determines that
market conditions warrant, each Fund may invest up to 100% of its assets in
money market instruments consisting of securities issued or guaranteed by the
U.S. government or its agencies or instrumentalities, receipts, including TR's,
TIGR's and CATS, money market funds, repurchase agreements, certificates of
deposit, time deposits, bank master notes and bankers' acceptances issued by
banks having net assets of at least $1 billion as of the end of their most
recent fiscal year, commercial paper rated at least A-1 by S&P or P-1 by
Moody's, and in cash. A Fund will not be pursuing its investment objective to
the extent that a substantial portion of its assets are invested in money market
securities.
 
Each Fund will restrict its investments in illiquid securities to 15% of its net
assets.
 
Each of the Funds may engage in securities lending and will limit such practice
to 33 1/3% of its assets.
 
Each Fund may purchase securities which have not been registered under the
Securities Act of 1933 (Rule 144A Securities).
 
Each Fund may purchase in options on stock indices to invest cash on an interim
basis. The aggregate premium paid on all options on stock indices cannot exceed
20% of the Fund's total assets.
 
In the event that a security owned by a Fund is downgraded below the stated
rating categories, the Advisor or SubAdvisor will take appropriate action with
regard to the security.
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
Since the Funds invest in equity securities, each Fund's shares will fluctuate
in value, and thus may be more suitable for long-term investors who can bear the
risk of short-term fluctuations. In addition, the market value of fixed income
securities bears an inverse relationship to changes in market interest rates,
which may affect the net asset value of shares. The longer the remaining
maturity of security, the greater is the effect of interest rate changes on its
market value. Generally, because of their fixed income features, convertible
securities will fluctuate in value to a lesser degree than the common stocks
into which they are convertible.
<PAGE>   48
 
 9
 
Changes in the value of a Fund's fixed income securities will not affect cash
income received from ownership of such securities, but will affect a Fund's net
asset value.
 
Securities rated BBB by S&P or Baa by Moody's are deemed by these rating
services to have some speculative characteristics, and adverse economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than is the case with higher-grade
bonds.
 
Investments in securities of foreign issuers may subject a Fund to different
risks than those attendant to investments in securities of U.S. issuers,
including differences in accounting, auditing and financial reporting standards,
the possibility of expropriation or confiscatory taxation, and political
instability. See "Description of Permitted investments."
 
Given the uncertainty of the future value of emerging growth companies and
companies in special equity situations, the risk of possible decline in the
value of the Emerging Growth Fund's net assets are significant. Companies in
which the Emerging Growth Fund invests may offer greater opportunities for
capital appreciation than larger, more established companies, but investment in
such companies may involve certain special risks. These risks may be due to the
greater business risks of small size, limited markets and financial resources,
narrow product lines and frequent lack of depth in management. The securities of
such companies are often traded in the over-the-counter market and may not be
traded in volumes typical on a national securities exchange. Thus, the
securities of emerging growth companies may be less liquid, and subject to more
abrupt or erratic market movements than securities of larger, more established
growth companies. Since a "special equity situation" may involve a significant
change from a company's past experiences, the uncertainties in the appraisal of
the future value of the company's equity securities and the risk of a possible
decline in the value of the Fund's investments are significant.
 
INVESTMENT LIMITATIONS
 
Each Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the U.S. government or its agencies or instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of the Fund would be invested in the securities of such issuer. This
restriction applies to 75% of a Fund's assets.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies or instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies are considered to
be in the same industries as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objective and policies; (b) enter into repurchase
agreements; and (c) engage in securities lending as described in this Prospectus
and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Funds. Fundamental policies cannot be changed with
respect to a Fund without the consent of a majority of the Fund's outstanding
shares.

THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of the Balanced, Value Momentum and Growth
Equity Funds and continuously reviews, supervises and administers each Fund's
investment program. The Advisor discharges its responsibilities subject to the
supervision of, and policies established by, the Trustees of the Trust. The
Trust's shares are not sponsored, endorsed or guaranteed by, and do not
constitute obligations or deposits of, the Advisor and are not guaranteed by the
FDIC, or any other governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .60% of the average daily net assets of the Growth Equity,
Value Momentum, Balanced and Blue Chip Funds, and .80% of the average daily net
assets of the Emerging Growth Fund. Although the advisory fee paid by the
Emerging Growth Fund is higher than advisory fees paid by other mutual funds,
the Trust believes that the fee is comparable to the advisory fee paid by many
other mutual funds with similar investment objectives and policies. The Advisor
may from time to time waive all or a portion of its fee in order to limit the
operating expenses of a Fund. Any such waiver is voluntary and may be terminated
at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, as predecessor to the
Advisor, was paid an advisory fee of .60%, of the average daily net assets of
the Growth Equity, Value Momentum, Balanced, and Blue Chip Growth Funds, and
 .80% of the average daily net assets of the Emerging Growth Fund.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of each Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
Richard Earnest, a Vice President of the Advisor, has served as team leader of
the Value Momentum Fund since its inception, and has been with the Advisor and
its predecessor, Union Bank, since 1964. Carl J. Colombo, a Vice President of
the Advisor, has served as team leader of the Balanced Fund since its inception,
and as team leader of the Growth Equity Fund since May, 1995. Mr. Colombo has
been with the Advisor and its predecessor, Union Bank, since 1985.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE SUBADVISOR
 
The Advisor and Bank of Tokyo-Mitsubishi Trust Company (the "SubAdvisor") have
entered into an investment subadvisory agreement relating to the Emerging Growth
and Blue Chip Growth Funds (the "Investment SubAdvisory Agreement"). Under the
Investment SubAdvisory Agreement, the SubAdvisor makes the day-to-day investment
decisions for the assets of the Emerging Growth and Blue Chip Growth Funds,
subject to the supervision of, and policies established by, the Advisor and the
Trustees of the Trust.
 
Bank of Tokyo-Mitsubishi Trust Company, headquartered at 1251 Avenue of the
Americas, New York, New York 10116, and with offices at 100 Broadway, New York,
New York 10005,
<PAGE>   50
 
 11
 
operates as a wholly-owned subsidiary of The Bank of Tokyo-Mitsubishi, Ltd. The
SubAdvisor was formed by the combination on April 1, 1996, of Bank of Tokyo
Trust Company, a wholly-owned subsidiary of The Bank of Tokyo, Ltd., and
Mitsubishi Bank Trust Company of New York, a wholly-owned subsidiary of The
Mitsubishi Bank, Ltd. Bank of Tokyo Trust Company was the surviving entity, and
changed its name to Bank of Tokyo-Mitsubishi Trust Company. Prior to the
combination, subadvisory services were provided by Bank of Tokyo Trust Company.
Bank of Tokyo Trust Company was established in 1955, and has provided trust
services since that time and management services since 1965.
 
The SubAdvisor serves as portfolio manager to bank common funds, employee
benefit funds and personal trust accounts, managing assets in money market,
equity and fixed income portfolios. As of April 1, 1996, the SubAdvisor managed
$750 million in individual portfolios and collective funds. In addition, the
SubAdvisor also serves as SubAdvisor to the Trust's Government Securities and
Convertible Securities Funds.
 
The SubAdvisor is entitled to a fee, which is calculated daily and paid monthly
out of the Advisor's fee, at an annual rate of .30% of the average daily net
assets of the Blue Chip Growth Fund and .50% of the average daily net assets of
the Emerging Growth Fund. For the fiscal year ended January 31, 1996, Bank of
Tokyo Trust Company, predecessor of the SubAdvisor, received .30% and .50% of
the average daily net assets of the Blue Chip Growth and Emerging Growth Funds,
respectively.
 
The day-to-day management of the Blue Chip Growth Fund's investments is the
responsibility of a team of investment professionals.
 
Seth E. Shalov has served as the portfolio manager to the Emerging Growth Fund
since its inception. Mr. Shalov has been a Senior Portfolio Manager with the
SubAdvisor and its predecessor, Bank of Tokyo Trust Company, since October,
1988.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of a Fund's Institutional Class
shares. Any such waiver is voluntary and may be terminated at any time in the
Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional and Cash
Sweep Class shares of the Trust and for the Investment Class shares of the
Convertible Securities, Government Securities, Emerging Growth, Blue Chip Growth
and International Equity Funds. Compensation for these services is paid under
the Administration Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days' written notice by either party, or upon assignment by the
Distributor. Investment Class shares of a Fund, which are
<PAGE>   51
 
 12
 
offered by a separate prospectus, may bear the costs of their distribution
expenses and, a sales charge is imposed on the sale of Investment Class shares
of the Funds. It is possible that an institution may offer different classes of
shares to its customers and thus receive different compensation with respect to
different classes of shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Funds may be made on days on which
both the New York Stock Exchange and Federal Reserve wire system are open for
business ("Business Days"). The minimum initial investment in a Fund is $2,000;
however, the minimum investment may be waived in the Distributor's discretion.
Shareholders may place orders by telephone.
 
Purchase orders will be effective if the Distributor receives an order before
4:00 p.m., Eastern time, and the Custodian receives Federal funds before the
close of business on the next Business Day. The purchase price of shares of a
Fund is the net asset value next determined after a purchase order is received
and accepted by the Trust. The net asset value per share of a Fund is determined
by dividing the total market value of a Fund's investments and other assets,
less any liabilities, by the total number of outstanding shares of a Fund. Net
asset value per share is determined daily as of 4:00 p.m., Eastern time, on any
Business Day. Purchases will be made in full and fractional shares of the Trust
calculated to three decimal places. The Trust reserves the right to reject a
purchase order when the Distributor determines that it is not in the best
interest of the Trust and/or its Shareholders to accept such order.
 
Shares of the Funds are offered only to residents of states in which the shares
are eligible for purchase.
 
Shareholders who desire to redeem shares of the Trust must place their
redemption orders prior to 4:00 p.m., Eastern time, on any Business Day for the
order to be accepted on that Business Day. The redemption price is the net asset
value of the Fund next determined after receipt by the Distributor of the
redemption order. Payment on redemption will be made as promptly as possible
and, in any event, within seven calendar days after the redemption order is
received.
 
Neither the Trust's transfer agent nor the Trust will be responsible for any
loss, liability, cost or expense for acting upon wire instructions or upon
telephone instructions that it reasonably believes to be genuine. The Trust and
its transfer agent will each employ reasonable procedures to confirm that
telephone instructions are genuine. Such procedures may include taping of
telephone conversations. If market conditions are extraordinarily active or
other extraordinary circumstances exist, and you experience difficulties placing
redemption orders by telephone, you may wish to consider placing your order by
other means.
 
PERFORMANCE
 
From time to time, the Funds may advertise yield and total return. These figures
will be based on historical earnings, and are not intended to indicate future
performance. The yield of a Fund refers to the annualized income generated by an
investment in the Fund over a specified 30-day period. The yield is calculated
by assuming that the same amount of income generated by the investment during
that period is generated in each 30-day period over one year and is shown as a
percentage of the investment.
 
The total return of a Fund refers to the average compounded rate of return to a
hypothetical investment for designated time periods (including, but not limited
to, the period from which the Fund commenced operations through the specified
date), assuming that the entire investment is redeemed at the end of each period
and assuming the reinvestment of all dividend and capital gain distributions.
The total return of a Fund may also be quoted as a dollar amount or on an
aggregate basis, an actual basis, without inclusion of any sales charge, or with
a reduced sales charge in
<PAGE>   52
 
 13
 
advertisements distributed to investors entitled to a reduced sales charge.
 
A Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local income tax treatment of a Fund or
its Shareholders. In addition, state and local tax consequences of investing in
a Fund may differ from the federal income tax consequences discussed below.
Accordingly, Shareholders are urged to consult their tax advisers regarding
specific questions as to federal, state and local income taxes. Additional
information concerning taxes is set forth in the Statement of Additional
Information.
 
TAX STATUS OF THE FUNDS:
 
Each Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. Each Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so as to be relieved of federal
income tax on net investment company taxable income and net capital gain (the
excess of net long-term capital gain over net short-term capital loss)
distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
A Fund will distribute substantially all of its net investment income (including
net short-term capital gain) and net capital gain to Shareholders. Dividends
from a Fund's net investment company taxable income are taxable to Shareholders
as ordinary income (whether received in cash or in additional shares) to the
extent of the Fund's earnings and profits. Dividends paid by a Fund to corporate
Shareholders will qualify for the dividends received deduction to the extent
derived from dividends received by the Fund from domestic corporations. A
portion of such dividends may be subject to the alternative minimum tax.
Distributions of net capital gain do not qualify for the dividends-received
deduction and are taxable to Shareholders as long-term capital gain, regardless
of how long Shareholders have held their shares and regardless of whether the
distributions are received in cash or in additional shares. Each Fund will make
annual reports to Shareholders of the federal income tax status of all
<PAGE>   53
 
 14
 
distributions, including the amount of dividends eligible for the
dividends-received deduction.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments, a
Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because each Fund distributes
all of its net investment income to its shareholders, a Fund may have to sell
portfolio securities to distribute such imputed income, which may occur at a
time when the Advisor would not have chosen to sell such securities and which
may result in a taxable gain or loss.
 
Income derived by a Fund from obligations of foreign issuers may be subject to
foreign withholding taxes. A Fund will not be able to elect to treat
Shareholders as having paid their proportionate share of such taxes.
 
Dividends declared by a Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
Each Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Investment income received directly by a Fund on direct U.S. obligations is
exempt from tax at the state level and may be exempt, depending on the state,
when received by a Shareholder as income dividends from a Fund provided certain
state-specific conditions are satisfied. Interest received on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. Each Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from a Fund is considered tax exempt in their
particular state.
 
Each sale, exchange, or redemption of Fund Shares is a taxable transaction to
the Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate portfolios of shares and different Classes of each fund. In
addition to the Funds, the Trust consists of the following funds: Treasury Money
Market Fund, Money Market Fund, California Tax-Free Money Market Fund,
Intermediate-Term Bond Fund, Limited Maturity Government Fund, California
Intermediate Tax-Free Bond Fund, Convertible Securities Fund, Government
Securities Fund and International Equity Fund. All consideration received by the
Trust for shares of any fund and all assets of such fund belong to that fund and
would be subject to liabilities related thereto. The Trust reserves the right to
create and issue shares of additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses. Please refer to "Financial Highlights" in this prospectus
for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management,
<PAGE>   54
 
 15
 
administrative and shareholder services to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings of Shareholders, but approval will be sought for certain changes
in the operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon the written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate
assistance and information to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of a
Fund is distributed in the form of monthly dividends to Shareholders of record.
Currently, capital gains of a Fund, if any, will be distributed at least
annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares at the net asset value next determined
following the record date, unless the Shareholder has elected to take such
payment in cash. Shareholders may change their election by providing written
notice to the Administrator at least 15 days prior to the change.
 
Dividends and distributions of a Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on Institutional Class shares will typically be higher
than the dividends payable on the Investment Class shares because of the
distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank, N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the 1940 Act.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Funds:
 
AMERICAN DEPOSITARY RECEIPTS (ADRs)-- Receipts typically issued by a U.S.
financial institution (a "depositary"), that evidence ownership interest in a
security or a pool of securities issued by a foreign issuer.
 
CONVERTIBLE BONDS AND CONVERTIBLE PREFERRED STOCK--Convertible bonds are bonds
convertible into a set number of shares of another form of security (usually
common stock) at a prestated price. Convertible bonds have characteristics
similar to both fixed income and equity securities. Convertible preferred stock
is a class of capital stock that pays dividends at a
<PAGE>   55
 
 16
 
specified rate and that has preference over common stock in the payment of
dividends and the liquidation of assets. Convertible preferred stock is
preferred stock exchangeable for a given number of common stock shares, and has
characteristics similar to both fixed-income and equity securities. Because of
the conversion feature, the market value of convertible bonds and convertible
preferred stock tend to move together with the market value of the underlying
stock. As a result, a Fund's selection of convertible bonds and convertible
preferred stock is based, to a great extent, on the potential for capital
appreciation that may exist in the underlying stock. The value of convertible
bonds and convertible preferred stock is also affected by prevailing interest
rates, the credit quality of the issuer and any call provisions.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
FUTURES AND OPTIONS ON FUTURES--Some futures strategies, including selling
futures, buying puts and writing calls, reduce a Fund's exposure to price
fluctuations. Other strategies, including buying futures, writing puts and
buying calls, tend to increase market exposure. Futures and options may be
combined with each other in order to adjust the risk and return characteristics
of the overall portfolio.
 
Options and futures can be volatile instruments, and involve certain risks that
if applied at an inappropriate time, could negatively impact a Fund's return.
 
INVESTMENT GRADE BONDS--Interest-bearing or discounted government or corporate
securities that obligate the issuer to pay the bondholder a specified sum of
money, usually at specific intervals, and to repay the principal amount of the
loan at maturity. Investment grade bonds are those rated BBB or better by S&P or
Baa or better by Moody's.
 
LOAN PARTICIPATIONS--Interests in loans to U.S. corporations (i.e., borrowers)
which are administered by the lending bank or agent for a syndicate of lending
banks, and sold by the lending bank or syndicate member ("intermediary bank").
In a loan participation, the borrower of the underlying loan will be deemed to
be the issuer of the participation interest (except to the extent a purchasing
Fund derives its rights from the intermediary bank). Because the intermediary
bank does not guarantee a loan participation in any way, a loan participation is
subject to the credit risks associated with the underlying corporate borrower.
In addition, in the event the underlying corporate borrower fails to pay
principal and interest when due, the Fund may encounter delays, expenses and
risks that are greater than those that would have been involved if the Fund had
purchased a direct obligation (such as commercial paper) of such borrower
because it may be necessary under the terms of the loan participation, for the
Fund to assert its rights against the borrower through the intermediary bank.
Moreover, under the terms of a loan participation, the purchasing Fund may be
regarded as a creditor of the intermediary bank (rather than of the underlying
corporate borrower), making it subject to the risk that the issuing bank may
become insolvent. Further, in the event of the bankruptcy or insolvency of the
corporate borrower, a loan participation may be subject to certain defenses that
can be asserted by such borrower as a result of improper conduct by the issuing
bank. The secondary market, if any, for these loan participations is limited,
and any such participation purchased by the Fund may be regarded as illiquid.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S.
<PAGE>   56
 
 17
 
Treasury obligations and obligation of agencies and instrumentalities of the
U.S. Government; (iii) high-quality commercial paper issued by U.S. and foreign
corporations; (iv) debt obligations with a maturity of one year or less issued
by corporations that issue high-quality commercial paper; and (v) repurchase
agreements involving any of the foregoing obligations entered into with
highly-rated banks and broker-dealers.
 
OPTIONS--Under a call option, the purchaser of the option has the right to
purchase, and the writer (the Fund) the obligation to sell, the underlying
security at the exercise price during the option period. A put option gives the
purchaser the right to sell, and the writer the obligation to purchase, the
underlying securities at the exercise price during the option period.
 
In addition, each Fund may buy options on stock indices to invest cash on an
interim basis. Such options will be listed on a national securities exchange. In
order to close out an option position, a Fund may enter into a "closing purchase
transaction"--the purchase of an option on the same security with the same
exercise price and expiration date as the option previously written on any
particular security. When the security is sold, a Fund effects a closing
purchase transaction so as to close out any existing option on that security.
 
There are risks associated with such investments, including the following: (1)
the success of a hedging strategy may depend on the ability of the Advisor or
SubAdvisor to predict movements in the prices of individual securities,
fluctuations in markets and movements in interest rates; (2) there may be an
imperfect correlation between the movement in prices of securities held by the
Fund and the price of options; (3) there may not be a liquid secondary market
for options; and (4) while a Fund will receive a premium when it writes covered
call options, it may not participate fully in a rise in the market value of the
underlying security.
 
REPURCHASE AGREEMENTS--Agreements by which a Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. A Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement. A
Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if a Fund realizes a loss in the sale of
the collateral. A Fund will enter into repurchase agreements only with financial
institutions deemed to present minimal risk of bankruptcy during the term of the
agreement based on established guidelines. Repurchase agreements are considered
loans under the 1940 Act.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
SECURITIES LENDING--In order to generate additional income, each Fund may lend
the securities in which it is invested pursuant to agreements requiring that the
loan be continuously secured by cash, securities of the U.S. Government or its
agencies or securities as collateral equal to 100% of the market value at all
times of the loaned securities. The lending Fund will continue to receive
interest on the loaned securities while simultaneously earning interest on the
investment of cash collateral. Collateral is marked to market daily to provide a
level of collateral at least equal to the market value of the loaned securities.
There may be risks of delay in receiving additional collateral should the
borrower of the securities fail financially.
 
SECURITIES OF FOREIGN ISSUERS--There may be certain risks connected with
investing in foreign securities, including risks of adverse political and
economic developments (including possible
<PAGE>   57
 
 18
 
governmental seizure or nationalization of assets), the possible imposition of
exchange controls or other governmental restrictions, including less uniformity
in accounting and reporting requirements, the possibility that there will be
less information on such securities and their issuers available to the public,
the difficulty of obtaining or enforcing court judgments abroad, restrictions on
foreign investments in other jurisdictions, difficulties in effecting
repatriation of capital invested abroad, and difficulties in transaction
settlements and the effect of delay on shareholder equity. Foreign securities
may be subject to foreign taxes, which reduce yield, and may be less marketable
than comparable U.S. securities. The Fund may be affected favorably or
unfavorably by changes in the exchange rates or exchange control regulations
between foreign currencies and the U.S. dollar. Changes in foreign currency
exchange rates may also affect the value of dividends and interest earned, gains
and losses realized on the sale of securities and net investment income and
gains, if any, to distributed to shareholders by a Fund.
 
STANDARD & POOR'S DEPOSITARY RECEIPTS ("SPDRs")--Interests in a unit investment
trust holding a portfolio of securities linked to the S&P 500 Index. SPDRs
closely track the underlying portfolio of securities, trade like a share of
common stock and pay periodic dividends proportionate to those paid by the
portfolio of stocks that constitutes the S&P 500 Index. For further information
regarding a Fund's investment in SPDRs, see the Statement of Additional
Information.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations that known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") are transferable through the Federal book-entry system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of such
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not
<PAGE>   58
 
 19
 
accurately reflect existing market interest rates. A demand instrument with a
demand notice period exceeding seven days may be considered illiquid if there is
no secondary market for such security.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date, and no interest
accrued to the Fund before settlement. These securities are subject to market
fluctuations due to changes, real or anticipated, in market interest rates and
the public's perception of the creditworthiness of the issuers and will have the
effect of leveraging the Fund's assets. A Fund will establish one or more
segregated accounts with the Custodian, and the Fund will maintain liquid,
high-grade assets in an amount at least equal in value to the Fund's commitments
to purchase when-issued securities.
 
WARRANTS--Securities that entitle the holder to buy a proportionate amount of
common stock at a specified price for a limited or unlimited period of time.
Warrants are often freely transferable and are traded on major stock exchanges.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Institutional Class shares of the CALIFORNIA INTERMEDIATE TAX-FREE BOND FUND
(the "Fund"). This summary is qualified in its entirety by reference to the more
detailed information provided elsewhere in this Prospectus and in the Statement
of Additional Information.
 
WHAT IS THE FUND'S INVESTMENT OBJECTIVE?  The Fund seeks to provide high current
income that is exempt from federal and State of California income taxes. See
"Investment Objective."
 
WHAT ARE THE FUND'S PERMITTED INVESTMENTS?  The Fund invests primarily in
investment grade bonds and notes issued by the State of California, its
agencies, instrumentalities and political sub-divisions, the income on which is
exempt from regular federal and State of California personal income taxes
("California Municipal Securities"). See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUND?  The investment
policies of the Fund entail certain risks and considerations of which an
investor should be aware. Shares of the Fund will fluctuate in value with the
value of the Fund's underlying portfolio securities. Values of fixed income
securities in which the Fund invests tend to vary inversely with interest rates,
and may be affected by other market and economic factors affecting the State of
California as well. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or any instrumentalities of the securities in which the Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Fund. See "The Advisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Institutional and Cash Sweep Class shares of the Trust and for the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment in the Trust is $2,000. A purchase order will be
effective if the Distributor receives an order prior to 4:00 p.m., Eastern time
and the Custodian receives federal funds before the close of business on the
next Business Day. Redemption orders must be placed prior to 4:00 p.m., Eastern
time on any Business Day for the order to be accepted that day. See "Purchase
and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of the Fund is distributed in the form of monthly
dividends to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

(1) The Advisor has agreed to waive its fee to the extent necessary to limit
    "Total Operating Expenses" to .22%. "Total Operating Expenses" have been
    restated to reflect current expenses and fee waivers. Absent fee waivers,
    "Advisory Fees" would have been .50% and "Total Operating Expenses" would
    have been .71%. The Advisor may terminate its waiver at any time in its sole
    discretion.

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF THE FUND AND SHOULD
NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES
MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist
the investor in understanding the various costs and expenses that may be
directly or indirectly borne by investors in the Institutional Class shares of
the Fund. Financial institutions that are the record owner of shares for the
account of their customers may impose separate fees for account services to
their customers. The Trust also offers Investment Class shares of the Fund which
are subject the same expenses, except that Investment Class shares are subject
to a sales load and distribution expenses. Additional information may be found
under "The Administrator" and "The Advisor."

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in sales charges, distribution costs, voting rights
and dividends. Except for these differences among the classes, each share of
each fund represents an equal proportionate interest in that fund. This
Prospectus relates to the Institutional Class shares of the Trust's California
Intermediate Tax-Free Bond Fund (the "Fund"). Information regarding the Trust's
other funds is contained in separate prospectuses that may be obtained from the
Trust's Distributor, SEI Financial Services Company, 680 East Swedesford Road,
Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVE
 
The California Intermediate Tax-Free Bond Fund seeks to provide high current
income that is exempt from federal and State of California income taxes.
 
There can be no assurance that the Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
Under normal market conditions, the Fund will invest primarily in bonds and
notes issued by the State of California, its agencies, instrumentalities, and
political sub-divisions, the income on which is exempt from regular federal and
State of California personal income taxes ("California Municipal Securities").
The Fund may also invest in bonds and notes of other states, territories, and
possessions of the U.S. and their agencies, authorities, instrumentalities and
political sub-divisions which are exempt from Federal income taxes and in shares
of other investment companies, specifically money market funds, which have
similar investment objectives.
 
Under normal market conditions, at least 80% of the Fund's assets will be
invested in bonds and notes rated AAA, AA, A or BBB by Standard & Poor's
Corporation ("S&P"), Aaa, Aa, A or Baa by Moody's Investors Service ("Moody's"),
or AAA, AA, A or BBB by Fitch Investors Service ("Fitch") and which pay interest
that is not treated as a preference item for purposes of the federal alternative
minimum tax. The Fund may purchase unrated securities that are determined by the
Advisor to be of comparable quality at the time of purchase pursuant to quality
standards set by the Board of Trustees. In the event that a security owned by
the Fund is downgraded below the stated ratings categories, the Advisor will
take appropriate action with regard to the security.
 
Under California law, a mutual fund must have at least 50% of its total assets
invested in California Municipal Securities at the end of each quarter of its
taxable year in order to be eligible to pay California residents dividends that
are wholly or partially exempt from California personal income taxes.
Accordingly, the Fund intends to maintain at least 65% of its assets in
California Municipal Securities, and may invest up to 100% of its assets in such
securities.
 
The Fund has no restrictions on the maturity of municipal securities in which it
may invest. The dollar weighted average portfolio maturity of the Fund will be
from three to ten years. Accordingly, the Fund seeks to invest in municipal
securities of such maturities which, in the judgment of the Advisor, will
provide a high level of current income consistent with prudent investment, with
consideration given to market conditions.
 
The Fund may purchase securities on a forward commitment or a when-issued basis
where such purchases are for investment and not for leveraging purposes;
however, the Fund may sell these securities before the settlement date if it is
deemed advisable. No additional forward
<PAGE>   65
 
 6
 
commitments will be made if more than 20% of the Fund's net assets would be so
committed.
 
The Fund may also invest in securities which have not been registered under the
Securities Act of 1933 (Rule 144A Securities). The Fund will restrict its
investment in illiquid securities to 15% of its net assets.
 
CALIFORNIA MUNICIPAL SECURITIES
 
The two principal classifications of California Municipal Securities are
"general obligation" and "revenue" bonds. General obligation bonds are secured
by the issuer's pledge of its full faith, credit, and taxing power for the
payment of principal and interest. Revenue bonds are payable only from the
revenues derived from a particular facility or class of facilities or, in some
cases, from the proceeds of a special excise tax or other specific revenue
source. Private activity bonds (formerly known as industrial revenue bonds) are
generally revenue bonds.
 
Certain California Municipal Securities are municipal lease revenue obligations
(or certificates of participation or "COPs"), which typically provide that the
municipality has no obligation to make lease or installment payments in future
years unless money is appropriated for such purpose. While the risk of
non-appropriation is inherent to COP financing, this risk is mitigated by the
Fund's policy to invest in COPs that are rated in one of the four highest rating
categories used by Moody's, S&P, or Fitch.
 
California Municipal Securities also include so-called Mello-Roos and assessment
district bonds, which are usually unrated instruments issued to finance the
building of roads and other public works and projects that are primarily secured
by real estate taxes levied on property located in the local community. Most of
these bonds do not seek agency ratings because the issues are too small, and in
most cases, the purchase of these bonds are based upon the Advisor's
determination that it is suitable for the Fund.
 
The Fund may also purchase, subject to a limit of 15% of its assets, California
Municipal Securities that are variable rate demand notes (or VRDNs).
 
For temporary defensive purposes during periods when the Advisor determines that
market conditions warrant, the Fund may invest up to 25% of its assets in
taxable money market instruments consisting of securities issued or guaranteed
by the U.S. Government, its agencies or instrumentalities, receipts, including
TR's, TIGR's and CATS, money market funds, repurchase agreements, and commercial
paper rated at least A-1 by S&P or P-1 by Moody's or Fitch 1 by Fitch. The Fund
also may hold a portion of its assets in cash. The Fund will not be pursuing its
investment objective to the extent that a substantial portion of its assets is
invested in money market securities, and as a result it may pay taxable
dividends to shareholders.
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
The ability of the State of California and its political sub-divisions to raise
money through property taxes and to increase spending has been the subject of
considerable debate and various constitutional initiatives and other
limitations. This process, and associated legal challenges, remains on-going. It
is not possible to predict the ultimate effect of these constitutional and other
initiatives, nor can there be any assurance that additional initiatives will not
be introduced in the coming years.
 
The market value of the Fund's fixed income investments will change in response
to interest rate changes and other factors. During periods of falling interest
rates, the values of outstanding fixed income securities generally rise.
Conversely, during periods of rising interest rates, the values of such
securities generally decline. Changes by recognized rating agencies in the
rating of any fixed income security and in the ability of an issuer to make
payments of interest and principal also affect the value of these investments.
Changes in the value of fund securities will not affect cash
<PAGE>   66
 
 7
 
income derived from these securities, but will affect the Fund's net asset
value.
 
Securities rated BBB by S&P or Fitch or Baa by Moody's are deemed by these
rating services to have some speculative characteristics, and adverse economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than with higher grade bonds.
 
INVESTMENT LIMITATIONS
 
The Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the United States or its agencies and instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of the Fund would be invested in the securities of such issuer provided,
however, that the Fund may invest up to 25% of its total assets without regard
to this restriction as permitted by applicable law.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies and instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent company.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objective and policies; and (b) enter into
repurchase agreements.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Fund. Fundamental policies cannot be changed with
respect to the Fund without the consent of a majority of the Fund's outstanding
shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of the Fund and continuously reviews,
supervises and administers the Fund's investment program. The Advisor discharges
its responsibilities subject to the supervision of, and policies established by,
the Trustees of the Trust. The Trust's shares are not sponsored, endorsed or
guaranteed by, and do not constitute obligations or deposits of, the Advisor and
are not guaranteed by the FDIC or any other governmental agency.
 
Under the Advisory Agreement, the Advisor is entitled to a fee, which is
calculated daily and paid monthly, at an annual rate of .50% of the average
daily net assets of the Fund. The Advisor may from time to time waive all or a
portion of its fee in order to limit the operating expenses of the Fund. Any
such waiver is voluntary and may be terminated at any time in the Advisor's sole
discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, predecessor of the
Advisor, was paid an advisory fee of .03% of the average daily net assets of the
Fund.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of the Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time,
<PAGE>   67
 
 8
 
the banks' investment management divisions were combined. Each of Union Bank and
The Bank of California, N.A. (or its predecessor bank) has been in banking since
the early 1900's, and historically, each has had significant investment
functions within its trust and investment division. Union Bank of California,
N.A., is a subsidiary of The Bank of Tokyo-Mitsubishi, Ltd.
 
Robert Bigelow has served as team leader of the Fund since October, 1994. Prior
to joining the Advisor's predecessor, Union Bank, in June, 1994, Mr. Bigelow
served as a portfolio manager at City National Bank from January, 1986 to June,
1994.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of the Fund's Institutional
Class shares. Any such waiver is voluntary, and may be terminated at any time in
the Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional and Cash
Sweep Class shares of the Trust and for the Investment Class shares of the
Convertible Securities, Government Securities, Emerging Growth, Blue Chip Growth
and International Equity Funds. Compensation for these services is paid under
the Administration Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days written notice by either party, or upon assignment by the
Distributor. Investment Class shares of the Fund may bear the costs of their
distribution expenses, and a sales charge is imposed on the sale of Investment
Class shares of the Fund. It is possible that an institution may offer different
classes of shares to its customers and thus receive different compensation with
respect to different classes of shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Fund may be made on days on which
both the New York Stock Exchange and the Federal Reserve wire system are open
for business ("Business Days"). The minimum initial investment in the Trust is
$2,000; however, the minimum investment may be waived in the Distributor's
discretion. Shareholders may place orders by telephone.
 
Purchase orders will be effective if the Distributor receives an order before
4:00 p.m., Eastern time, and the Custodian receives federal funds before the
close of business on the next Business Day. The purchase price of shares of the
Fund is the net asset value next determined after a purchase order is received
and accepted by the Trust. The net asset value per share of the Fund is
determined by dividing the total market value of the Fund's investments and
other assets, less any
<PAGE>   68
 
 9
 
liabilities, by the total number of outstanding shares of the Fund. Net asset
value per share is determined daily as of 4:00 p.m., Eastern time, on any
Business Day. Purchases will be made in full and fractional shares of the Trust
calculated to three decimal places. The Trust reserves the right to reject a
purchase order when the Distributor determines that it is not in the best
interest of the Trust and/or its Shareholders to accept such order.
 
Shares of the Fund are offered only to residents of states in which the shares
are eligible for purchase.
 
Shareholders who desire to redeem shares of the Trust must place their
redemption orders prior to 4:00 p.m., Eastern time, on any Business Day for the
order to be accepted on that Business Day. The redemption price is the net asset
value of the Fund next determined after receipt by the Distributor of the
redemption order. Payment on redemption will be made as promptly as possible
and, in any event, within seven calendar days after the redemption order is
received.
 
Neither the Trust's transfer agent nor the Trust will be responsible for any
loss, liability, cost or expense for acting upon wire instructions or upon
telephone instructions that it reasonably believes are genuine. The Trust and
its transfer agent will each employ reasonable procedures to confirm that
telephone instructions are genuine. Such procedures may include taping of
telephone conversations. If market conditions are extraordinary active or other
extraordinary circumstances exist, and you experience difficulties placing
redemption orders by telephone, you may wish to consider placing your order by
other means.
 
PERFORMANCE
 
From time to time, the Fund may advertise yield and total return. These figures
will be based on historical earnings, and are not intended to indicate future
performance. The yield of the Fund refers to the annualized income generated by
an investment in the Fund over a specified 30-day period. The yield is
calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year
and is shown as a percentage of the investment.
 
The total return of the Fund refers to the average compounded rate of return to
a hypothetical investment, for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gains
distributions. The total return of the Fund may also be quoted as a dollar
amount or on an aggregate basis, an actual basis, without inclusion of any sales
charge, or with a reduced sales charge in advertisements distributed to
investors entitled to a reduced sales charge.
 
The Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising, and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical
<PAGE>   69
 
 10
 
share price fluctuations or total returns to a benchmark while measures of
benchmark correlation indicate how valid a comparative benchmark might be.
Measures of volatility and correlation are calculated using averages of
historical data and cannot be calculated precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local income tax treatment of the Fund or
its Shareholders. In addition, state and local tax consequences of an investment
in the Fund may differ from the federal income tax consequences described below.
Accordingly, Shareholders are urged to consult their tax advisers regarding
specific questions as to federal, state and local income taxes. Additional
information concerning taxes is set forth in the Statement of Additional
Information.
 
TAX STATUS OF THE FUND:
 
The Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. The Fund intends to qualify for the
special tax treatment afforded regulated investment companies of the Internal
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on that part of its net investment company taxable income and
net capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
The Fund will distribute all of its net investment income (including net
short-term capital gain) to Shareholders. If, at the close of each quarter of
its taxable year, at least 50% of the value of the Fund's assets consists of
obligations the interest on which is excludable from gross income, the Fund may
pay "exempt-interest dividends" to its Shareholders. Those dividends constitute
the portion of the aggregate dividends as designated by the Fund, equal to the
excess of the excludable interest over certain amounts disallowed as deductions.
Exempt-interest dividends are excludable from a Shareholder's gross income for
federal income tax purposes, but may have certain collateral federal income tax
consequences, including alternative minimum tax. Additional information
concerning taxes is set forth in the Statement of Additional Information.
 
Current federal tax law limits the types and volume of bonds qualifying for the
federal income tax exemption of interest, which may have an effect on the
ability of the Fund to purchase sufficient amounts of tax-exempt securities to
satisfy the Code's requirements for the payment of "exempt-interest" dividends.
 
Any dividends paid out of income realized by the Fund on taxable securities will
be taxable to Shareholders as ordinary income, whether received in cash or in
additional shares, to the extent of the Fund's earnings and profits and will not
qualify for the dividends received deductions for corporate shareholders.
Distributions of net capital gain also do not qualify for the dividends received
deduction and are taxable to Shareholders as long-term capital gain, regardless
of how long the Shareholder has held Fund Shares, and regardless of whether the
distributions are received in cash or additional shares. The Fund will make
annual reports to Shareholders of the federal income tax status of all
distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments,
the Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because the Fund
<PAGE>   70
 
 11
 
distributes all of its net investment income to Shareholders, the Fund may have
to sell Fund securities to distribute such imputed income, which may occur at a
time when the Advisor would not have chosen to sell such securities and which
may result in a taxable gain or loss.
 
Dividends declared by the Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
The Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level, and may be exempt, depending on the state,
when received by a Shareholder as income dividends from the Fund, provided
certain state-specific conditions are satisfied. Interest realized on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. The Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from the Fund is considered tax exempt in their
particular state.
 
Each sale, exchange, or redemption of Fund shares is a taxable transaction to
the Shareholder.
 
Furthermore, entities or persons who are "substantial users" (or persons related
to "substantial users") of facilities financed by "private activity bonds" or
"industrial development bonds" should consult their tax advisors before
purchasing shares. (See the Statement of Additional Information.)
 
CALIFORNIA TAXES:
 
The Fund intends to qualify to pay dividends to Shareholders that are exempt
from California personal income tax ("California exempt-interest dividends").
The Fund will qualify to pay California exempt-interest dividends if (1) at the
close of each quarter of the Fund's taxable year, at least 50 percent of the
value of the Fund's total assets consists of obligations the interest on which
would be exempt from California personal income tax if the obligations were held
by an individual ("California Tax Exempt Obligations") and (2) the Fund
continues to qualify as a regulated investment company.
 
If the Fund qualifies to pay California exempt-interest dividends, dividends
distributed to Shareholders will be considered California exempt-interest
dividends (1) if they are designated as exempt-interest dividends by the Fund in
a written notice to Shareholders mailed within 60 days of the close of the
Fund's taxable year and (2) to the extent the interest received by the Fund
during the year on California Tax Exempt Obligations exceeds expenses of the
Fund that would be disallowed under California personal income tax law as
allocable to tax exempt interest if the Fund were an individual. If the
aggregate dividends so designated exceed the amount that may be treated as
California exempt-interest dividends, only that percentage of each dividend
distribution equal to the ratio of aggregate California exempt-interest
dividends to aggregate dividends so designated will be treated as a California
exempt-interest dividend. The Fund will notify Shareholders of the amount of
California exempt-interest dividends each year.
 
Corporations subject to California franchise tax that invest in the Fund may not
be entitled to exclude California exempt-interest dividends from income.
 
Dividend distributions that do not qualify for treatment as California
exempt-interest dividends will be taxable to Shareholders at ordinary income tax
rates for California personal income tax
<PAGE>   71
 
 12
 
purposes to the extent of the Fund's earnings and profits.
 
Interest on indebtedness incurred or continued by a Shareholder in connection
with the purchase of shares of the Fund will not be deductible for California
personal income tax purposes if the Fund distributes California exempt-interest
dividends.
 
The foregoing is a general, abbreviated summary of certain of the provisions of
the California Revenue and Taxation Code presently in effect as they directly
govern the taxation of Shareholders subject to California personal income tax.

GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate series of shares and different classes of each fund. In addition
to the Fund, the Trust consists of the following funds: Treasury Money Market
Fund, Money Market Fund, California Tax-Free Money Market Fund, Growth Equity
Fund, Value Momentum Fund, Limited Maturity Government Fund, Balanced Fund,
Intermediate-Term Bond Fund, Blue Chip Growth Fund, Emerging Growth Fund,
Convertible Securities Fund, Government Securities Fund and International Equity
Fund. All consideration received by the Trust for shares of any fund and all
assets of such fund belong to that fund, and would be subject to liabilities
related thereto. The Trust reserves the right to create and issue shares of
additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses. Please refer to "Financial Highlights" in this prospectus
for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings but approval will be sought for certain changes in the operation
of the Trust and for the election of Trustees under certain circumstances. In
addition, a Trustee may be removed by the remaining Trustees or by Shareholders
at a special meeting called upon the written request of Shareholders owning at
least 10% of the outstanding shares of the Trust. In the event that such a
meeting is requested the Trust will provide appropriate assistance and
information to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management

Corporation, 680 East Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of
the Fund is distributed in the form of monthly dividends to Shareholders of
record. Currently, capital gains of the Fund, if any, will be distributed at
least annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares at the net asset value next determined
following the record date, unless the Shareholder has elected to take such
payment in cash. Shareholders may change their election by providing written
notice to the Administrator at least 15 days prior to the change.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on the Institutional Class shares will typically be higher
than the dividends payable on the Investment Class shares because of the
distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Fund:
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term, debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial paper; and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and
broker-dealers.
 
MUNICIPAL FORWARDS--Municipal Forwards are forward commitments for the purchase
of tax-exempt bonds with a specified coupon to be delivered by an issuer at a
future date, typically exceeding 45 days but normally less than one year after
the commitment date. Municipal forwards are normally used as a refunding
mechanism for bonds that may only be redeemed on a designated future date. As
with forward commitments, and when-issued securities, municipal forwards are
subject to market fluctuations due to changes, real or anticipated, in market
interest rates between the commitment date and the settlement date and will have
the effect of leveraging the Fund's assets. Municipal forwards may be considered
to be illiquid investments. The Fund will maintain liquid, high-grade securities
in a segregated
<PAGE>   73
 
 14
 
account in an amount at least equal to the purchase price of the municipal
forward.
 
MUNICIPAL SECURITIES--Municipal securities consist of (i) debt obligations
issued by or on behalf of public authorities to obtain funds to be used for
various public facilities, for refunding outstanding obligations, for general
operating expenses and for lending such funds to other public institutions and
facilities, and (ii) certain private activity and industrial development bonds
issued by or on behalf of public authorities to obtain funds to provide for the
construction, equipment, repair or improvement of privately operated facilities.
Municipal notes include general obligation notes, tax anticipation notes,
revenue anticipation notes, bond anticipation notes, certificates of
indebtedness, demand notes and construction loan notes. Municipal bonds include
general obligation bonds, revenue or special obligation bonds, private activity
and industrial development bonds. General obligation bonds are backed by the
taxing power of the issuing municipality. Revenue bonds are backed by the
revenues of a project or facility, tolls from a toll bridge, for example. The
payment of principal and interest on private activity and industrial development
bonds generally is dependent solely on the ability of the facility's user to
meet its financial obligations and the pledge, if any, of real and personal
property so financed as security for such payment.
 
PARTICIPATION INTERESTS--Participation interests are interests in municipal
securities from financial institutions such as commercial and investment banks,
savings and loan associations and insurance companies. These interests may take
the form of participations, beneficial interests in a trust, partnership
interests or any other form of indirect ownership that allows the Fund to treat
the income from the investment as exempt from federal income tax. The Fund
invests in these participation interests in order to obtain credit enhancement
or demand features that would not be available through direct ownership of the
underlying Municipal Securities.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
REPURCHASE AGREEMENTS--Agreements by which the Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will actual or constructive
possession of the securities held as collateral for the repurchase agreement.
The Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its right to
dispose of the collateral securities or if the Fund realizes a loss on the sale
of the collateral. The Fund will enter into a repurchase agreement only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based upon established guidelines. Repurchase agreements
are considered loans under the 1940 Act.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component
<PAGE>   74
 
 15
 
parts of such obligations known as Separately Traded Registered Interest and
Principal Securities ("STRIPS") that are transferable through the Federal
book-entry system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. California
Municipal Securities may also be acquired through the purchase of municipal
forwards. The interest rates on these securities may be reset daily, weekly,
quarterly or some other reset period and may have a floor or ceiling on interest
rate changes. There is a risk that the current interest rate on such obligations
may not accurately reflect existing market interest rates. A demand instrument
with a demand notice period exceeding seven days may be considered illiquid if
there is no secondary market for such security.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Institutional Class shares of the LIMITED MATURITY GOVERNMENT FUND (the "Fund").
This summary is qualified in its entirety by reference to the more detailed
information provided elsewhere in this Prospectus and in the Statement of
Additional Information.
 
WHAT IS THE FUND'S INVESTMENT OBJECTIVE?  The Fund seeks a high level of income
and relative price stability consistent with safety of capital. See "Investment
Objective."
 
WHAT ARE THE FUND'S PERMITTED INVESTMENTS?  The Fund will invest at least 65% of
its assets in U.S. Treasury notes and other direct obligations of the U.S.
Treasury, and obligations issued or guaranteed by U.S. Government agencies or
instrumentalities, including mortgage-backed securities issued or guaranteed by
U.S. Government agencies such as the Government National Mortgage Association
("GNMA"), the Federal National Mortgage Association ("FNMA"), or the Federal
Home Loan Mortgage Corporation ("FHLMC"). See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUND?  The investment
policies of the Fund entail certain risks and considerations of which an
investor should be aware. There can be no assurance that the Fund will achieve
its investment objective. The Fund's investments are subject to market and
interest rate fluctuations which may affect the value of the Fund's shares.
During periods of falling interest rates, the values of outstanding fixed income
securities generally rise. Conversely, during periods of rising interest rates,
the values of such securities generally decline. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or instrumentalities of the securities in which any Fund invests guarantees only
the payment of principal and interest on the guaranteed security, and does not
guarantee the yield or value of the security or yield or value of shares of that
Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator to the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Institutional and Cash Sweep Class shares of the Trust and for the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment in the Fund's Institutional Class is $2,000. A
purchase order will be effective if the Distributor receives an order prior to
4:00 p.m., Eastern time and the Custodian receives Federal funds before the
close of business on the next Business Day. Redemption orders must be placed
prior to 4:00 p.m., Eastern time on any Business Day for the order to be
accepted that day. See "Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of the Fund is determined and declared on each
Business Day as a dividend for Shareholders of record as of the close of
business on that day. Any capital gain is distributed at least annually.
Distributions are paid in additional shares unless the Shareholder elects to
take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF THE FUND AND SHOULD
NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES
MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist
the investor in understanding the various costs and expenses that may be
directly or indirectly borne by investors in the Institutional Class Shares of
the Fund. Financial institutions that are the record owner of shares for the
account of their customers may impose separate fees for account services to
their customers. The Trust also offers Investment Class shares of the Fund,
which are subject to the same expenses, except that Investment Class shares are
subject to a sales charge and distribution expenses. Additional information may

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in sales charges, distribution costs, voting rights
and dividends. Except for these differences among the classes, each share of
each fund represents an equal proportionate interest in that fund. This
Prospectus relates to the Institutional Class shares of the Trust's Limited
Maturity Government Fund (the "Fund"). Information regarding the Trust's other
funds is contained in separate prospectuses that may be obtained from the
Trust's Distributor, SEI Financial Services Company, 680 East Swedesford Road,
Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVE
 
The Limited Maturity Government Fund seeks a high level of income, relative to
funds with like investment objectives, and relative price stability consistent
with safety of capital.
 
There can be no assurance that the Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
The Fund will invest at least 65% of its assets in U.S. Treasury notes, other
direct obligations of the U.S. Treasury, and obligations issued or guaranteed by
U.S. Government agencies or instrumentalities, including mortgage-backed
securities issued or guaranteed by U.S. Government agencies such as GNMA, FNMA
or FHLMC.
 
With respect to its remaining assets, the Fund may invest in: restricted
securities which have not been registered under the Securities Act of 1933 (Rule
144A Securities); receipts, including TR's, TIGR's and CATS; high quality
certificates of deposit, time deposits and bankers' acceptances issued or
guaranteed by United States banks with assets of at least $1 billion, including
comparable U.S. dollar denominated obligations of foreign branches of such
banks; privately issued mortgage-backed securities; money market funds;
repurchase agreements involving securities that constitute permissible
investments for the Fund; and Federal funds.
 
The Fund will not invest more than 15% of its assets in illiquid securities. The
Trust considers Federal funds investments maturing in more than 7 days to be
illiquid. In addition, the Fund may engage in securities lending. The Fund will
limit such practice to 33 1/3% of its total assets.
 
The Fund may purchase securities on a forward commitment or when-issued basis
where such purchases are for investment and not for leveraging purposes;
however, the Fund may sell these securities before the settlement date if it is
deemed advisable. No additional forward commitments will be made if more than
20% of the Fund's net assets would be so committed.
 
Guarantees of the Fund's securities by the U.S. Government or its agencies or
instrumentalities guarantee only the payment of principal and interest on the
guaranteed securities, and do not guarantee the securities' yield or value or
the yield or value of the Fund's Institutional Class shares.
 
Under normal circumstances, the Fund will maintain an average weighted maturity
of three years or less. The measure of average maturity will use the expected
life of securities held by the Fund.
 
The Advisor will seek to enhance the yield of the Fund by taking advantage of
yield disparities or other factors that occur in the government securities and
money markets. The Fund may dispose of any security prior to its maturity if
such disposition and reinvestment of the proceeds are expected to enhance yield
consistent with the
<PAGE>   81
 
 6
 
Advisor's judgment as to a desirable maturity structure or if such disposition
is believed to be advisable due to other circumstances or considerations.
 
Mortgage-backed securities purchased by the Fund will be issued or guaranteed as
to payment of principal and interest by the United States government or its
agencies or instrumentalities or, if issued by private issuers, rated in one of
the two highest rating categories by a nationally recognized rating agency. The
principal governmental issuers or guarantors of mortgage-backed securities are
the GNMA, FNMA, and FHLMC. Obligations of GNMA are backed by the full faith and
credit of the United States Government, while obligations of FNMA and FHLMC are
supported by the respective agency only. The Fund may purchase mortgage-backed
securities that are backed or collateralized by fixed, adjustable or floating
rate mortgages.
 
Mortgage-backed securities that are not issued or guaranteed by the United
States Government or its agencies or instrumentalities, including securities
nominally issued by a governmental entity (such as the Resolution Trust
Corporation), are not obligations of a governmental entity, and thus may bear a
risk of nonpayment. The timely payment of principal and interest normally is
supported, at least partially, by various forms of insurance or guarantees.
There can be no assurance, however, that such credit enhancements will support
full payment of the principal and interest on such obligations.
 
The portfolio turnover rate for the Fund for the fiscal year ended January 31,
1996 was 186%. This rate of portfolio turnover may result in higher brokerage
execution costs and higher levels of capital gains.
 
For temporary defensive purposes when the Advisor determines that market
conditions warrant, the Fund may invest up to 100% of its assets in money market
instruments consisting of securities issued or guaranteed by the U.S.
government, its agencies or instrumentalities, repurchase agreements, receipts,
including TR's, TIGR's and CATS, certificates of deposit, time deposits, bank
master notes and bankers' acceptances issued by banks having net assets of at
least $1 billion as of the end of their most recent fiscal year or rated at
least A-1 by Standard & Poor's Corporation ("S&P") or P-1 by Moody's Investor
Services ("Moody's") and in cash. To the extent that the Fund is engaged in
temporary defensive investing, it will not be pursuing its investment objective.
 
For additional information, see "Description of Permitted Investments."
 
ELIGIBILITY UNDER FEDERAL CREDIT
UNION ACT
 
The Fund is limited to making investments and engaging in investment
transactions that are permissible for federal credit unions. Therefore, the Fund
will not invest in zero coupon securities with maturities greater than 10 years.
All collateralized mortgage obligations ("CMOs") and real estate mortgage
investment conduits ("REMICs") purchased by the Fund will comport with the
average life, average life sensitivity and price sensitivity tests of Section
703.5(g) of the National Credit Union Association's ("NCUA") Rules and
Regulations. The Fund may purchase stripped mortgage-backed securities ("SMBS"),
residual interests in CMOs or REMICs, or non-floating/adjustable rate CMOs or
REMICs that do not comport with Section 703.5(g) of the NCUA Rules and
Regulations only if the instrument is purchased to reduce the Fund's interest
rate risk and is subjected to the monitoring, reporting, evaluation and pricing
requirements of Section 703.5(i) of the NCUA Rules and Regulations. Floating or
adjustable rate CMOs or REMICs that do not comply with Section 703.5(g) may be
purchased by the Fund if they comport with the provisions of Section 703.5(j) of
the NCUA Rules and Regulations.
 
Shares of the Fund are designed to qualify as eligible investments for federally
chartered credit unions pursuant to Section 107(7), 107(8) and 107(15) of the
Federal Credit Union Act and Part 703 of the NCUA Rules and Regulations. The
Fund will continually monitor changes in the
<PAGE>   82
 
 7
 
applicable laws, rules and regulations governing eligible investments, including
new investments, for federally chartered credit unions and will take such action
as may be necessary to assure that the Fund's investments, and, therefore,
shares of the Fund, continue to qualify as eligible investments under the
Federal Credit Union Act.
 
Sections 107(7), 107(8) and 107(15) of the Federal Credit Union Act set forth
those securities, deposits and other obligations in which federally chartered
credit unions may invest. The Fund's investments consist exclusively of assets
designed to qualify as eligible investments if owned directly by a federally
chartered credit union. Shares of the Fund may or may not qualify as eligible
investments for particular state chartered credit unions. Accordingly, the Fund
encourages, but does not require, each state chartered credit union to consult
qualified legal counsel concerning whether the Fund's shares are permissible
investments for that credit union. While the Advisor will ensure that the Fund
follows investment policies set forth herein, the Fund cannot be responsible for
compliance by participating state chartered credit unions with limitations on
permissible investments to which they may be subject.
 
RISK FACTORS
 
The market value of the Fund's fixed income investments will change in response
to interest rate changes and other factors. During periods of falling interest
rates, the values of outstanding fixed income securities generally rise.
Conversely, during periods of rising interest rates, the values of such
securities generally decline. Securities with longer maturities are subject to
greater fluctuations in value than securities with shorter maturities. Changes
by recognized agencies in the rating of any fixed income security, and in the
ability of an issuer to make payments of interest and principal, also affect the
value of these investments. Changes in the value of Fund securities will not
affect cash income derived from these securities, but will affect the Fund's net
asset value.
 
Mortgage-backed securities are subject to prepayment of the underlying
mortgages. During periods of declining interest rates, prepayment of mortgages
underlying these securities can be expected to accelerate. When the mortgage-
backed securities held by a Fund are prepaid, the Fund must reinvest the
proceeds in securities the yields of which reflect prevailing interest rates,
which may be lower than those of the prepaid security.
 
Some of the permitted investments for the Fund may not be permitted investments
for particular state chartered credit unions. See "The Trust."
 
INVESTMENT LIMITATIONS
 
The Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the United States, its agencies or instrumentalities and repurchase agreements
involving such securities) if as a result more than 5% of the total assets of
the Fund would be invested in the securities of such issuer. This restriction
applies to 75% of the Fund's assets.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies and instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of the parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objectives and policies, and (b) enter into
repurchase agreements.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental

and non-fundamental investment limitations are set forth in the Statement of
Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Fund. Fundamental policies cannot be changed with
respect to the Fund without the consent of a majority of the Fund's outstanding
shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of the Fund and continuously reviews,
supervises and administers the Fund's investment program. The Advisor discharges
its responsibilities subject to the supervision of, and policies established by,
the Trustees of the Trust. The Trust's shares are not sponsored, endorsed or
guaranteed by, and do not constitute obligations or deposits of, the Advisor and
are not guaranteed by the FDIC or any other governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .30% of the average daily net assets of the Fund. The Advisor
may from time to time waive all or a portion of its fee in order to limit the
operating expenses of the Fund. Any such waiver is voluntary, and may be
terminated at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, predecessor of the
Advisor, was paid an advisory fee of .30% of the average daily net assets of the
Fund.
 
MERUS-UCA Capital Management ("the Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of the Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
Martin Standish has served as team leader of the Fund since its inception. Mr.
Standish is a Vice President of the Advisor, and has been with the Advisor and
its predecessor, Union Bank, since June, 1992. Prior to his employment with the
Advisor and its predecessor, Mr. Standish served as a portfolio manager at
Patterson Capital from November, 1991 to June, 1992 and at Pacific Century
Advisors from February, 1990 to November, 1991. He earned his M.B.A. at the
University of Texas at Dallas from 1989 to 1991, and has a B.S. in Finance from
Colorado State University.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
Administration Agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may
<PAGE>   84
 
 9
 
waive its fee or reimburse various expenses to the extent necessary to limit the
total operating expenses of the Fund's Institutional Class shares. Any such
waiver is voluntary, and may be terminated at any time in the Administrator's
sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional and Cash
Sweep Class shares of the Trust and for the Investment Class shares of the
Convertible Securities, Government Securities, Emerging Growth, Blue Chip Growth
and International Equity Funds. Compensation for these services is paid under
the Administration Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution is renewable annually and may be terminated by the
Distributor, by a majority vote of the outstanding shares of the Trust upon not
more than 60 days written notice by either party, or upon assignment by the
Distributor. Investment Class shares of the Fund may bear costs of their
distribution expenses, and a sales charge is imposed on the sale of Investment
Class shares of the Fund. It is possible that an institution may offer different
classes of shares to its customers, and thus receive different compensation with
respect to different classes of shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Fund may be made on days on which
both the New York Stock Exchange and Federal Reserve wire system are open for
business ("Business Days"). The minimum initial investment in the Trust is
$2,000; however, the minimum investment may be waived at the Distributor's
discretion.
 
Purchase orders will be effective as of the day received by the Distributor if
the Distributor receives the order before 4:00 p.m., Eastern time and the
Custodian receives Federal funds before the close of business on the next
Business Day. The purchase price of shares of the Fund is the net asset value
next determined after a purchase order is received and accepted by the Trust.
The net asset value per share of the Fund is determined by dividing the total
market value of the Fund's investments and other assets, less any liabilities,
by the total number of outstanding shares of the Fund. Net asset value per share
is determined daily as of 4:00 p.m., Eastern time, on any Business Day.
Purchases will be made in full and fractional shares of the Fund calculated to
three decimal places. The Trust reserves the right to reject a purchase order
when the Distributor determines that it is not in the best interest of the Trust
and/or its Shareholders to accept such order.
 
Shares of the Fund are offered only to residents of states in which the shares
are eligible for purchase.
 
Shareholders who desire to redeem shares of the Fund must place their redemption
orders prior to 4:00 p.m., Eastern time, on any Business Day for the order to be
accepted on that Business Day. The redemption price is the net asset value of
the Fund next determined after receipt by the Distributor of the redemption
order. Payment on redemption will be made as promptly as possible and, in any
event, within seven calendar days after the redemption order is received.
 
Neither the Trust's Transfer Agent nor the Trust will be responsible for any
loss, liability, cost, or expense for acting upon wire instructions or upon
telephone instructions that it reasonably believes are genuine. The Trust and
its transfer agent will each employ reasonable procedures to confirm that
telephone instructions are genuine. Such procedures may include taping of
telephone conversations. If market conditions are extraordinarily active or
other extraordinary circumstances exist, and you experience difficulties placing
redemption orders by telephone, you may wish to consider placing your order by
other means.

PERFORMANCE
 
From time to time, the Fund may advertise yield and total return. These figures
will be based on historical earnings, and are not intended to indicate future
performance. The yield of the Fund refers to the annualized income generated by
an investment in the Fund over a specified 30-day period. The yield is
calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year,
and is shown as a percentage of the investment.
 
The total return of the Fund refers to the average compounded rate of return to
a hypothetical investment, for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gain
distributions. The total return of the Fund may also be quoted as a dollar
amount or on an aggregate basis, an actual basis, without inclusion of any sales
charge, or with a reduced sales charge in advertisements distributed to
investors entitled to a reduced sales charge.
 
The Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising, and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark, while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial, or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local income tax treatment of the Fund or
its Shareholders. In addition, state and local tax consequences of an investment
in the Fund may differ from the federal income tax consequences described below.
Accordingly, Shareholders are urged to consult their tax advisers regarding
specific questions as to federal, state, and local income taxes. Additional
information concerning taxes is set forth in the Statement of Additional
Information.
 
TAX STATUS OF THE FUND:
 
The Fund is treated as a separate entity for Federal income tax purposes, and is
not combined with the Trust's other Funds. The Fund intends to continue to
qualify for the special tax treatment afforded regulated investment companies by
the Internal Revenue Code of 1986, as amended (the "Code"), so that it will be
relieved of federal income tax on that part of its net investment company
taxable income and net capital gain (the
<PAGE>   86
 
 11
 
excess of net long-term capital gain over net short-term capital loss)
distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
The Fund will distribute all of its net investment income (including, net
short-term capital gain) to Shareholders. Dividends from the Fund's net
investment company taxable income are taxable to Shareholders as ordinary income
(whether received in cash or in additional shares) to the extent of the Fund's
earnings and profits. Any net capital gains will be distributed at least
annually, and will be taxed to Shareholders as long-term capital gains,
regardless of how long the Shareholder has held shares and regardless of whether
the distributions are received in cash or in additional shares. Dividends and
distributions of net investment capital gain do not qualify for the
dividends-received deduction for corporate shareholders. The Fund will provide
annual reports to Shareholders of the federal income tax status of all
distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments,
the Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because the Fund distributes
all of its net investment income to Shareholders, the Fund may have to sell Fund
securities to distribute such imputed income which may occur at a time when the
Advisor would not have chosen to sell such securities, and which may result in a
taxable gain or loss.
 
Dividends declared by the Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
The Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level when received directly by the Fund, and may
be exempt, depending on the state, when received by a Shareholder as income
dividends from the Fund, provided certain state-specific conditions are
satisfied. Interest realized on repurchase agreements collateralized by U.S.
government obligations normally is not exempt from state tax. The Fund will
inform Shareholders annually of the percentage of income and distributions
derived from direct U.S. Treasury obligations. Shareholders should consult their
tax advisors to determine whether any portion of the income dividends received
from the Fund is considered tax exempt in their particular state.
 
Each sale, exchange, or redemption of Fund shares is a taxable event to the
Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate series of shares and different classes of each fund. In addition
to the Fund, the Trust consists of the following funds: Treasury Money Market
Fund, Money Market Fund, California Tax-Free Money Market Fund, Growth Equity
Fund, Value Momentum Fund, Balanced Fund, Intermediate-Term Bond Fund,
California Intermediate Tax-Free Bond Fund, Blue Chip Growth Fund, Emerging
Growth Fund, Convertible Securities Fund, Government Securities Fund and
International Equity Fund. All consideration received by the Trust for shares of
any fund and all assets of such fund belong to that fund, and would be subject
to liabilities related thereto. The Trust reserves the right to create and issue
shares of additional funds.
<PAGE>   87
 
 12
 
The Trust pays its expenses, including fees of its service providers, audit and
legal expenses, expenses of preparing prospectuses, proxy solicitation material
and reports to shareholders, costs of custodial services and registering the
shares under Federal and State securities laws, pricing, insurance expenses,
litigation and other extraordinary expenses, brokerage costs, interest charges,
taxes and organization expenses. Please refer to "Financial Highlights" in this
prospectus for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to that fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings of shareholders, but approval will be sought for certain changes
in the operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate
assistance and information to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semi-annually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania,
19087-1658.
 
DIVIDENDS
 
On each Business Day, the Fund declares a dividend from net investment income
(not including capital gain) as of the close of trading on the New York Stock
Exchange (generally 4:00 p.m. Eastern time) to shareholders of record at the
previous net asset value calculation. Dividends are normally paid (and, where
applicable, reinvested) on the first Business Day of the following month.
Currently, capital gains of the Fund, if any, will be distributed at least
annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares unless the Shareholder has elected to take
such payment in cash. Shareholders may change their election by providing
written notice to the Administrator at least 15 days prior to the distribution.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The amount of dividends payable on Institutional Class shares will typically be
higher than the dividends payable on the Investment Class shares because of the
distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.

CUSTODIAN
 
CoreStates Bank, NA., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the Trust. The
Custodian holds cash, securities and other assets of the Trust as required by
the Investment Company Act of 1940, as amended (the "1940 Act").
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Fund:
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
FEDERAL FUNDS--Federal funds are funds held by a regional Federal Reserve Bank
for the account of a bank ("Fed Bank") that is a member of such Federal Reserve
Bank. A loan of Federal funds is an unsecured loan at a negotiated interest rate
for a negotiated time period, generally overnight, of Federal funds by one Fed
Bank to another. Since, pursuant to an exemption from the reserve requirements
imposed upon depository institutions by the Board of Governors of the Federal
Reserve System (the "FRB"), the borrowing Fed Bank is not required to maintain
reserves on the borrowed Federal funds, the interest rate it pays on such
borrowings is generally higher than the rate it pays on other deposits of
comparable size and maturity that are subject to reserve requirements. In
addition, a "depository institution" or other exempt institution such as the
Trust may, under Regulation D of the FRB, in effect, make loans of Federal funds
by instructing a correspondent or other willing Fed Bank at which it maintains
an account to loan Federal funds on its behalf. Loans of Federal funds are not
federally insured.
 
The Fund may make unsecured loans of Federal funds to United States banks
provided that: 1) the accounts of such banks are federally insured; 2) the
interest received is at the market rate for Federal funds transactions; and 3)
the transaction has a specified maturity of one or more business days or the
Fund is able to require repayment at any time.
 
In the event the borrower of Federal funds enters into a bankruptcy or other
insolvency proceeding, the Fund could experience delays and incur expenses in
recovering cash. Further, the possibility exists that in such an instance, the
borrowing institution may not be able to repay the borrowed funds.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality, dollar
denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial paper; and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and broker
dealers.
 
MORTGAGE-BACKED SECURITIES--Mortgage-backed securities are generally issued or
guaranteed by U.S. Government agencies, such as GNMA, FNMA, or FHLMC. GNMA
mortgage-backed certificates are mortgage-backed securities of the modified
pass-through type, which means that both interest and principal payments
(including prepayments) are passed through monthly to the holder of the
certificate. Each GNMA certificate evidences an interest in a specific pool of
mortgage loans insured by the Federal Housing Administration or the Farmers Home
Administration or guaranteed by the
<PAGE>   89
 
 14
 
Veterans Administration. FNMA, a federally chartered and stockholder-owned
corporation, issues pass-through certificates which are guaranteed as to payment
of principal and interest by FNMA. FHLMC, a corporate instrumentality of the
United States, issues participation certificates which represent an interest in
mortgages held in FHLMC's portfolio. FHLMC guarantees the timely payment of
interest and the ultimate collection of principal. Securities issued or
guaranteed by FNMA and FHLMC are not backed by the full faith and credit of the
United States.
 
There can be no assurance that the United States Government would provide
financial support to FNMA or FHLMC if necessary in the future.
 
Adjustable rate mortgage securities ("ARMs") are pass-through certificates
representing ownership interests in a pool of adjustable rate mortgages and the
resulting cash flow from those mortgages. Unlike conventional debt securities,
which provide for periodic (usually semi-annually) payments of interest and
payments of principal at maturity or on specified call dates, ARMs provide for
monthly payments based on a pro rata share of both periodic interest and
principal payments and prepayments of principal on the underlying mortgage pool
(less GNMA's, FNMA's, or FHLMC's fees and any applicable loan servicing fees).
 
Collateralized mortgage obligations ("CMOs") are bonds generally issued by
single purpose, stand-alone finance subsidiaries or trusts established by
financial institutions, government agencies, investment banks, or other similar
institutions, and collateralized by pools of mortgage loans. Payments of
principal and interest on the collateral mortgages are used to pay debt service
on the CMO. In a CMO, a series of bonds or certificates is issued in multiple
classes. Each class of CMOs, often referred to as a "tranche," is issued at a
specific coupon rate and has a stated maturity or final distribution date. The
principal and interest payment on the underlying mortgages may be allocated
among the classes of CMOs in several ways. Typically, payments of principal,
including any prepayments, on the underlying mortgages would be applied to the
classes in the order of their respective stated maturities or final distribution
dates, so that no payment of principal will be made on CMOs of a class until all
CMOs of other classes having earlier stated maturities or final distribution
dates have been paid in full.
 
One or more classes of CMOs may have coupon rates that reset periodically based
on an index, such as the London Interbank Offered Rate ("LIBOR"). The Fund may
purchase fixed, adjustable, or "floating" rate CMOs that are collateralized by
fixed rate or adjustable rate mortgages that are guaranteed as to payment of
principal and interest by an agency or instrumentality of the United States
Government, are directly guaranteed as to payment of principal and interest by
the issuer, which guarantee is collateralized by United States Government
securities, or are collateralized by privately issued fixed rate or adjustable
rate mortgages.
 
Real Estate Mortgage Investment Conduits ("REMICs") are private entities formed
for the purpose of holding a fixed pool of mortgages secured by an interest in
real property. REMICs are similar to CMOs in that they issue multiple classes of
securities.
 
REPURCHASE AGREEMENTS--Agreements by which the Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement.
The Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its right to
dispose of the collateral securities or if the Fund realizes a loss on the sale
of the collateral. The Fund will enter into repurchase agreements only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based on established guidelines. Repurchase agreements are
considered loans under the 1940 Act.
<PAGE>   90

RULE 144A SECURITIES--Rule 144A securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of securities.
 
SECURITIES LENDING--In order to generate additional income, the Fund may lend
the securities in which it is invested pursuant to agreements requiring that the
loan be continuously secured by cash, securities of the U.S. Government or its
agencies or any combination of cash and such securities as collateral equal to
100% of the market value at all times of the loaned securities. The lending Fund
will continue to receive interest on the loaned securities while simultaneously
earning interest on the investment of cash collateral. Collateral is marked to
market daily to provide a level of collateral at least equal to the value of the
loaned securities. There may be risks of delay in receiving additional
collateral or risks of delay in recovery of the securities or even loss of
rights in the collateral should the borrower of the securities fail financially.
 
U.S. GOVERNMENT AGENCY SECURITIES--Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the Federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS-- Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date, and no interest
accrued to the Fund before settlement. These securities are subject to market
fluctuation
<PAGE>   91

due to changes, real or anticipated, in market interest rates and the public's
perception of the creditworthiness of the issuer, and will have the effect of
leveraging the Fund's assets. The Fund will establish one or more segregated
accounts with the Custodian, and the Fund will maintain liquid, high-grade
assets in an amount at least equal in value to the Fund's commitments to
purchase when-issued securities.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Institutional Class shares of the INTERNATIONAL EQUITY FUND (the "Fund"). This
summary is qualified in its entirety by reference to the more detailed
information provided elsewhere in the Prospectus and in the Statement of
Additional Information.
 
WHAT IS THE FUND'S INVESTMENT OBJECTIVE?  THE INTERNATIONAL EQUITY FUND seeks to
provide long-term capital appreciation by investing primarily in a diversified
portfolio of equity securities of non-U.S. issuers. See "Investment Objective."
 
WHAT ARE THE FUND'S PERMITTED INVESTMENTS?  The Fund invests primarily in equity
securities (common stocks, securities convertible into common stocks, preferred
stocks, warrants and rights to purchase common stock) of non-U.S. issuers. See
"Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUNDS?  The investment
policies of the Fund entail certain risks and considerations of which an
investor should be aware. The Fund may purchase common stocks and other equity
securities that are volatile and may fluctuate in value more than other types of
investments. In addition, the Fund will invest in securities of foreign
companies that involve special risks and considerations not typically associated
with investing in U.S. companies. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE SUBADVISOR?  Tokyo - Mitsubishi Asset Management (U.K.), Ltd. serves
as the SubAdvisor to the Fund. See "The SubAdvisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust . See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Institutional and Cash Sweep Class shares of the Trust and for the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment in the Trust is $2,000. A purchase order will be
effective if the Distributor receives an order prior to 4:00 p.m., Eastern time
and the Custodian receives Federal funds before the close of business on the
next Business Day. The purchase price is the net asset value next determined
after a purchase order is received and accepted by the Trust. Redemption orders
must be placed prior to 4:00 p.m., Eastern time on any Business Day for the
order to be accepted that day. See "Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of the Fund is periodically declared and paid as a
dividend to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF THE FUND AND SHOULD
NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES
MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist
the investor in understanding the various costs and expenses that may be
directly or indirectly borne by investors in the Institutional Class shares of
the Fund. Financial institutions that are the record owner of shares for the
account of their customers may impose separate fees for account services to
their customers. The Trust also offers Investment Class shares of the Fund which
are subject to the same expenses, except that Investment Class shares are
subject to sales charges and distribution expenses. Additional information may
be found under "The Administrator", "The Advisor" and "The SubAdvisor."

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Institutional Class shares of the Trust's International Equity Fund (the
"Fund") Information regarding the Trust's other funds is contained in separate
prospectuses that may be obtained from the Trust's Distributor, SEI Financial
Services Company, 680 East Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVE
 
THE INTERNATIONAL EQUITY FUND seeks to provide long-term capital appreciation by
investing primarily in a diversified portfolio of equity securities of non-U.S.
issuers.
 
There can be no assurance that the Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
Under normal market circumstances, at least 65% of the Fund's assets will be
invested in the following equity securities of non-U.S. issuers: common stocks,
securities convertible into common stocks, preferred stocks, warrants and rights
to purchase common stock. Under normal market conditions, at least 65% of the
Fund's total assets will be invested in securities of issuers organized under
the laws of at least five countries other than the United States that are
included in the Morgan Stanley Capital International Europe, Australia and Far
East Index (the "EAFE Index").(1)
 
Countries may be over- or under-weighted in comparison to the EAFE Index based
upon the Advisor's and SubAdvisor's view of forecasted rates of returns.
Regional and individual country weightings, therefore, may vary from the EAFE
Index benchmark. The Advisors and SubAdvisors will select individual securities
for the Fund on the basis of their undervaluation in relation to other
securities. The Fund expects its investments to emphasize companies with market
capitalizations in excess of $100,000,000.
 
The Fund will typically invest in equity securities listed on recognized foreign
exchanges, but may also invest up to 15% of its total assets in securities
traded in over-the-counter markets. Equity securities of non-U.S. issuers may
also be purchased in the form of sponsored or unsponsored American Depositary
Receipts ("ADRs") and sponsored or unsponsored European Depositary Receipts
("EDRs").
 
The Fund may enter into forward foreign currency contracts as a hedge against
possible variations in foreign exchange rates. A forward foreign currency
contract is a commitment to purchase or sell a specified currency at a specified
date, at a specified price. The Fund may enter into forward foreign currency
contracts to hedge a specific security transaction or to hedge a portfolio
position. These contracts may be bought and sold to protect the Fund, to some
degree, against a possible loss resulting from an adverse change in the
relationship between foreign currencies. The Fund may also invest in options on
currencies.
 
The Fund may invest in futures and options on futures for the purpose of
achieving the Fund's objectives. The Fund may invest in futures and related
options based on any type of security or index traded on U.S. or foreign
exchanges or over the counter, as long as the underlying security or securities
represented by an index, are permitted investments of the Fund. Such futures
contracts

    International which does not sponsor and is in no way affiliated with the
    International Equity Fund.
<PAGE>   98

may include index contracts and contracts for foreign Currencies. The Fund may
enter into futures contracts and options on futures only to the extent that its
obligations under such contracts or transactions, together with options on
securities or indices represent not more than 25% of the Fund's assets.
 
The premium paid on options on securities positions will not exceed 10% of the
Fund's net assets at the time such options are entered into by the Fund. The
aggregate premium paid on all options on stock indices will not exceed 20% of a
Fund's total assets.
 
The Fund's remaining assets may be invested in investment grade bonds and
debentures issued by non-U.S. or U.S. companies, obligations of supranational
entities, securities issued or guaranteed by foreign and U.S. governments, and
foreign and U.S. commercial paper. Certain of these instruments may have
floating or variable interest rate provisions. In addition, the Fund may invest
in securities of issuers whose principal activities are in countries with
emerging markets. The Fund defines an emerging market country as any country
whose economy and market the World Bank or the United Nations considers to be
emerging or developing. The Fund may also purchase shares of closed-end
investment companies that invest in the securities of issuers in a single
country or region and shares of open-end management investment companies.
 
For temporary defensive purposes during periods when the Advisor determines that
market conditions warrant, the Fund may invest up to 100% of its assets in money
market instruments and in cash. The Fund will not be pursuing its investment
objective to the extent that a substantial portion of its assets are invested in
money market securities.
 
The Fund will restrict its investment in illiquid securities to 15% of its net
assets.
 
The Fund may engage in securities lending and will limit such practice to
33 1/3% of its assets.
 
The Fund may purchase securities, which have not been registered under the
Securities Act of 1933 (Rule 144A Securities).
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
Since the Fund invests in equity securities, the Fund's shares will fluctuate in
value, and thus may be more suitable for long-term investors who can bear the
risk of short-term fluctuations.
 
There may be certain risks connected with investing in foreign securities,
including risks of adverse political and economic developments (including
possible governmental seizure or nationalization of assets), the possible
imposition of exchange controls or other governmental restrictions, including
less uniformity in accounting and reporting requirements, the possibility that
there will be less information on such securities and their issuers available to
the public, the difficulty of obtaining or enforcing court judgments abroad,
restrictions on foreign investments in other jurisdictions, difficulties in
effecting repatriation of capital invested abroad, and difficulties in
transaction settlements and the effect of delay on shareholder equity. Foreign
securities may be subject to foreign taxes, which reduce yield, and may be less
marketable than comparable U.S. securities. The value of the Fund's investments
denominated in foreign currencies will depend on the relative strengths of those
currencies and the U.S. dollar, and the Fund may be affected favorably or
unfavorably by changes in the exchange rates or exchange control regulations
between foreign currencies and the U.S. dollar. Changes in foreign currency
exchange rates may also affect the value of dividends and interest earned, gains
and losses realized on the sale of securities and net investment income and
gains, if any, to distributed to shareholders by the Fund.
 
Forward foreign currency contracts do not eliminate fluctuations in the
underlying prices of securities. Rather, they simply establish a rate of
<PAGE>   99
 
 7
 
exchange which one can achieve at some future point in time. Additionally,
although such contracts tend to minimize the risk of loss due to a decline in
the value of the hedged currency at the same time, they tend to limit any
potential gain which might result should the value of such currency increase.
 
The Fund's investments in emerging markets can be considered speculative, and
therefore, may offer higher potential for gains and losses than developed
markets of the world. With respect to any emerging country, there is the greater
potential for nationalization, expropriation or confiscatory taxation, political
changes, government regulation, social instability or diplomatic developments
(including war) which could affect adversely the economies of such countries or
investments in such countries. In addition, it may be difficult to obtain and
enforce a judgment in the courts of such countries. The economies of developing
countries generally are heavily dependent upon international trade and,
accordingly, have been and may continue to be adversely affected by trade
barriers, exchange controls, managed adjustments in relative currency values and
other protectionist measures imposed or negotiated by the countries with which
they trade.
 
Securities rated BBB by Standard & Poor's Corporation ("S&P") or Baa by Moody's
Investors Service, Inc. ("Moody's") are deemed by these ratings services to have
some speculative characteristics and adverse economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than is the case with higher grade bonds.
 
INVESTMENT LIMITATIONS
 
The Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the U.S. government or its agencies or instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of the Fund would be invested in the securities of such issuer. This
restriction applies to 75% of a Fund's assets. For purposes of this investment
limitation, each foreign governmental issuer is deemed a separate issuer.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies or instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objective and policies; (b) enter into repurchase
agreements; and (c) engage in securities lending as described in this Prospectus
and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Fund. Fundamental policies cannot be changed with
respect to the Fund without the consent of a majority of the Fund's outstanding
shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor continuously
reviews, supervises and administers the Fund's
<PAGE>   100
 
 8
 
investment program. The Advisor discharges its responsibilities subject to the
supervision of, and policies established by, the Trustees of the Trust. The
Trust's shares are not sponsored, endorsed or guaranteed by, and do not
constitute obligations or deposits of, the Advisor and are not guaranteed by the
FDIC or any other governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .95% of the average daily net assets of the Fund. Although the
advisory fee paid by the Fund is higher than advisory fees paid by other mutual
funds, the Trust believes that the fee is comparable to the advisory fee paid by
many other mutual funds with similar investment objectives and policies. The
Advisor may from time to time waive all or a portion of its fee in order to
limit the operating expenses of the Fund. Any such waiver is voluntary and may
be terminated at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, Ltd. predecessor of the
Advisor, was paid an advisory fee of .85% of the average daily net assets of the
Fund.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of the Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A., (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE SUBADVISOR
 
The Advisor and Tokyo-Mitsubishi Asset Management (U.K.), Ltd. (the
"SubAdvisor"), have entered into an investment subadvisory agreement relating to
the Fund (the "Investment SubAdvisory Agreement"). Under the Investment
SubAdvisory Agreement, the SubAdvisor makes the day-to-day investment decisions
for the assets of the Fund, subject to the supervision of, and policies
established by, the Advisor and the Trustees of the Trust. The Trust's shares
are not sponsored, endorsed or guaranteed by and do not constitute obligations
or deposits of the SubAdvisor and are not guaranteed by the FDIC or any other
governmental agency.
 
Tokyo-Mitsubishi Asset Management (U.K.), Ltd., 12-15 Finsbury Circus, London
EC2 M7BT operates as a subsidiary of The Bank of Tokyo-Mitsubishi, Ltd.
Established in 1989, the SubAdvisor provides active global investment services
for segregated funds and specialist fund management.
 
Prior to February, 1995, the SubAdvisor had not previously served as the
investment advisor to mutual funds. As of April 1, 1996, Tokyo-Mitsubishi Asset
Management (U.K.), Ltd., managed assets of $2.2 billion in individual portfolios
and collective funds.
 
The SubAdvisor is entitled to a fee, which is calculated daily and paid monthly
out of the Advisor's fee, at an annual rate of .30% of the average daily net
assets of the Fund.
 
Andrew Richmond has served as portfolio manager of the Fund since its inception.
Mr. Richmond has been with the SubAdvisor and its predecessor, Bank of Tokyo
Asset Management (U.K.), Ltd., since 1990, and has served as senior equity
investment manager since June, 1992.

THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of the Fund's Institutional
Class shares. Any such waiver is voluntary, and may be terminated at any time in
the Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional and Cash
Sweep Class shares of the Trust and for the Investment Class shares of the
Convertible Securities, Government Securities, Emerging Growth, Blue Chip Growth
and International Equity Funds. Compensation for these services is paid under
the Administration Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days written notice by either party, or upon assignment by the
Distributor. Investment Class shares of the Fund may bear the costs of their
distribution expenses and, a sales charge is imposed on the sale of Investment
Class shares of the Fund. It is possible that an institution may offer different
classes of shares to its customers and thus receive different compensation with
respect to different classes of shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Fund may be made on days on which
both the New York Stock Exchange and Federal Reserve wire system are open for
business ("Business Days"). The minimum initial investment in the Fund is
$2,000; however, the minimum investment may be waived in the Distributor's
discretion. Shareholders may place orders by telephone.
 
Purchase orders will be effective if the Distributor receives an order before
4:00 p.m., Eastern time, and the Custodian receives Federal funds before the
close of business on the next Business Day. The purchase price of shares of the
Fund is the net asset value next determined after a purchase order is received
and accepted by the Trust. The net asset value per share of the Fund is
determined by dividing the total market value of the Fund's investments and
other assets, less any liabilities, by the total number of outstanding shares of
a Fund. Net asset value per share is determined daily as of 4:00 p.m., Eastern
time, on any Business Day. Purchases will be made in full and fractional shares
of the Fund calculated to three decimal places. The Trust reserves the right to
reject a purchase order when the Distributor determines that it is not in the
best interest of the Trust and/or its Shareholders to accept such order.
 
Shares of the Fund are offered only to residents of states in which the shares
are eligible for purchase.
 
Shareholders who desire to redeem shares of the Trust must place their
redemption orders prior to 4:00 p.m., Eastern time, on any Business Day for the
order to be accepted on that Business Day. The redemption price is the net asset
value of the Fund next determined after receipt by the Distributor of the
redemption order. Payment on
<PAGE>   102
 
 10
 
redemption will be made as promptly as possible and, in any event, within seven
calendar days after the redemption order is received.
 
Neither the Trust's transfer agent nor the Trust will be responsible for any
loss, liability, cost or expense for acting upon wire instructions or upon
telephone instructions that it reasonably believes to be genuine. The Trust and
its transfer agent will each employ reasonable procedures to confirm that
telephone instructions are genuine. Such procedures may include taping of
telephone conversations. If market conditions are extraordinarily active or
other extraordinary circumstances exist, and you experience difficulties placing
redemption orders by telephone, you may wish to consider placing your order by
other means.
 
PERFORMANCE
 
From time to time, the Fund may advertise yield and total return. These figures
will be based on historical earnings and are not intended to indicate future
performance. The yield of the Fund refers to the annualized income generated by
an investment in the Fund over a specified 30-day period. The yield is
calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year
and is shown as a percentage of the investment.
 
The total return of the Fund refers to the average compounded rate of return to
a hypothetical investment for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gain
distributions. The total return of the Fund may also be quoted as a dollar
amount or on an aggregate basis, an actual basis, without inclusion of any sales
charge, or with a reduced sales charge in advertisements distributed to
investors entitled to a reduced sales charge.
 
The Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios,
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has
<PAGE>   103
 
 11
 
been made to present a detailed explanation of the federal, state, or local
income tax treatment of the Fund or its Shareholders. In addition, state and
local tax consequences of an investment in the Fund may differ from the federal
income tax consequences discussed below. Accordingly, Shareholders are urged to
consult their tax advisers regarding specific questions as to federal, state and
local income taxes. Additional information concerning taxes is set forth in the
Statement of Additional Information.
 
TAX STATUS OF THE FUND:
 
The Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. The Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on net investment company taxable income and net capital gain
(the excess of net long-term capital gain over net short-term capital loss)
distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
The Fund will distribute substantially all of its net investment income
(including net short-term capital gain) and net capital gain to Shareholders.
Dividends from the Fund's net investment company taxable income will be taxable
to Shareholders as ordinary income (whether received in cash or in additional
shares) to the extent of the Fund's earnings and profits. Dividends paid by the
Fund to corporate Shareholders will qualify for the deduction for dividends
received by corporations to the extent derived from dividends received by the
Fund from domestic corporations. Distributions of net capital gain are taxable
to Shareholders as long-term capital gain, regardless of how long Shareholders
have held their shares and regardless of whether the distributions are received
in cash or in additional shares. Dividends and distributions of capital gain
paid by the Fund do not qualify for the dividends received deduction for
corporate Shareholders. The Fund will provide annual reports to Shareholders of
the federal income tax status of all distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments,
the Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because the Fund distributes
all of its net investment income to its shareholders, the Fund may have to sell
portfolio securities to distribute such imputed income, which may occur at a
time when the Advisor or SubAdvisor would not have chosen to sell such
securities and which may result in a taxable gain or loss.
 
Income derived by the Fund from securities of foreign issuers may be subject to
foreign withholding taxes. The Fund expects to elect to treat Shareholders as
having paid their proportionate share of such taxes.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level and may be exempt, depending on the state,
when received by a Shareholder as income dividends from the Fund, provided
certain state-specific conditions are satisfied. Interest realized on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. The Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from the Fund is considered tax exempt in their
particular state.
 
Dividends declared by the Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on the last day of
December 31 of the year declared, if paid by the Fund any time during the
following January.
<PAGE>   104
 
 12
 
The Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Each sale, exchange, or redemption of Fund Shares is a taxable transaction to
the Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate portfolios of shares and different Classes of each fund. In
addition to the Fund, the Trust consists of the following funds: Treasury Money
Market Fund, Money Market Fund, California Tax-Free Money Market Fund,
Intermediate-Term Bond Fund, Limited Maturity Government Fund, California
Intermediate Tax-Free Bond Fund, Convertible Securities Fund, Government
Securities Fund, Balanced Fund, Value Momentum Fund, Blue Chip Growth Fund,
Growth Equity Fund and Emerging Growth Fund. All consideration received by the
Trust for shares of any fund and all assets of such fund belong to that fund and
would be subject to liabilities related thereto. The Trust reserves the right to
create and issue shares of additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings but approval will be sought for certain changes in the operation
of the Trust and for the election of Trustees under certain circumstances. In
addition, a Trustee may be removed by the remaining Trustees or by Shareholders
at a special meeting called upon the written request of Shareholders owning at
least 10% of the outstanding shares of the Trust. In the event that such a
meeting is requested the Trust will provide appropriate assistance and
information to the Shareholders requesting the information.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of
the Fund is periodically declared and paid as a dividend to Shareholders of
record. Currently, capital gains of the Fund, if any, will be distributed at
least annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares at the net asset value next determined
following the record date, unless the Shareholder has elected to take such
payment in cash.
<PAGE>   105
 
 13
 
Shareholders may change their election by providing written notice to the
Administrator at least 15 days prior to the change.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on Institutional Class shares will typically be higher
than the dividends payable on the Investment Class shares because of the
distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
State Street Bank and Trust Company, 225 Franklin Street, Boston, Massachusetts
02110 (the "Custodian"), acts as Custodian of the assets of the Fund. The
Custodian holds cash, securities and other assets of the Fund as required by the
Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Fund:
 
AMERICAN DEPOSITARY RECEIPTS ("ADRs") and EUROPEAN DEPOSITARY RECEIPTS
("EDRs")--Receipts, typically issued by a U.S. financial institution (a
"depositary"), that evidence ownership interests in a security or a pool of
securities issued by a foreign issuer and deposited with the depositary. ADRs
include American Depositary Shares and New York Shares. EDRs, which are
sometimes referred to as Continental Depositary Receipts ("CDRs"), are receipts,
typically issued by a non-U.S. financial institution, that evidence ownership
interests in a security or a pool of securities issued by either a U.S. or
foreign issuer. ADRs, EDRs and CDRs may be available for investment through
"sponsored" or "unsponsored" facilities. A sponsored facility is established
jointly by the issuer of the security underlying the receipt and a depositary,
whereas an unsponsored facility may be established by a depositary without
participation by the issuer of the receipt's underlying security.
 
Holders of an unsponsored depositary receipt generally bear all the costs of the
unsponsored facility. The depositary of an unsponsored facility frequently is
under no obligation to distribute shareholder communications received from the
issuer of the deposited security or to pass through to the holders of the
receipts voting rights with respect to the deposited securities.
 
CONVERTIBLE PREFERRED STOCK--Convertible preferred stock is a class of capital
stock that pays dividends at a specified rate and has preference over common
stock in the payment of dividends and the liquidation of assets. Convertible
preferred stock is preferred stock exchangeable for a given number of common
stock shares and has characteristics similar to both fixed-income and equity
securities. Because of the conversion feature, the market value of convertible
preferred stock tends to move together with the market value of the underlying
common stock. As a result, the Fund's selection of convertible preferred stock
is based, to a great extent, on the potential for capital appreciation that may
exist in the underlying common stock. The value of convertible preferred stock
is also affected by prevailing interest rates, the credit quality of the issuer
and any call provisions.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted
<PAGE>   106
 
 14
 
Investments" for discussions of these various instruments, and see "Investment
Objectives and Policies" for more information about any policies and limitations
applicable to their use.
 
FORWARD FOREIGN CURRENCY CONTRACTS-- The Fund may conduct its foreign currency
exchange transactions on a spot (i.e., cash) basis at the spot rate prevailing
in the foreign currency exchange market or through entering into forward
currency contracts to protect against uncertainty in the level of future
exchange rates between particular currencies or between foreign currencies in
which the Fund's securities are or may be denominated. A forward contract
involves an obligation to purchase or sell a specific currency amount at a
future date, which may be any fixed number of days from the date of the
contract, agreed upon by the parties, at a price set at the time of the
contract. Under normal circumstances, consideration of the prospect for changes
in currency exchanges rates will be incorporated into the Fund's long-term
investment strategies. However, the Advisor and SubAdvisor believe that it is
important to have the flexibility to enter into forward currency contracts when
it determines that the best interests of the Fund will be served.
 
When the Advisor and SubAdvisor believe that the currency of a particular
country may suffer a significant decline against another currency, the Fund may
enter into a currency contract to sell, for the appropriate currency, the amount
of foreign currency approximating the value of some or all of the Fund's
securities denominated in such foreign currency.
 
At the maturity of a forward contract, the Fund may either sell a fund security
and make delivery of the foreign currency, or it may retain the security and
terminate its contractual obligation to deliver the foreign currency by
purchasing an "offsetting" contract with the same currency trader, obligating it
to purchase on the same maturity date, the same amount of the foreign currency.
The Fund may realize a gain or loss from currency transactions.
 
FUTURES AND OPTIONS ON FUTURES--Some futures strategies, including selling
futures, buying puts and writing calls, reduce the Fund's exposure to price
fluctuations. Other strategies, including buying futures, writing puts and
buying calls, tend to increase market exposure. Futures and options may be
combined with each other in order to adjust the risk and return characteristics
of the overall portfolio.
 
Options and futures can be volatile instruments, and involve certain risks that
if applied at an inappropriate time, could negatively impact a Fund's return.
 
MONEY MARKET INSTRUMENTS--Money Market securities are high-quality,
dollar-denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits issued by
highly-rated U.S. banks and U.S. branches of foreign banks having net assets of
at least $1 billion as of the end of their most recent fiscal year; (ii) U.S.
Treasury obligations and obligations of agencies and instrumentalities of the
U.S. Government; (iii) high-quality commercial paper issued (i.e., rated A-1 by
S&P or P-1 by Moody's) by U.S. and foreign corporations; (iv) debt obligations
with a maturity of one year or less issued by corporations that issue
high-quality commercial paper; and (v) repurchase agreements involving any of
the foregoing obligations entered into with highly-rated banks and
broker-dealers.
 
OBLIGATIONS OF SUPRANATIONAL ENTITIES-- Obligations of supranational entities
are established through the joint participation of several governments, and
include the Asian Development Bank, the Inter-American Development Bank,
International Bank for Reconstruction and Development (World Bank), African
Development Bank, European Economic Community, European Investment Bank and the
Nordic Investment Bank.
 
OPTIONS--Under a call option, the purchaser of the option has the right to
purchase, and the writer (the Fund) the obligation to sell, the underlying
security at the exercise price during the option
<PAGE>   107
 
 15
 
period. A put option gives the purchaser the right to sell, and the writer the
obligation to purchase, the underlying securities at the exercise price during
the option period.
 
In addition, the Fund may buy options on stock indices to invest cash on an
interim basis. Such options will be listed on a U.S. or foreign securities
exchange. In order to close out an option position, the Fund may enter into a
"closing purchase transaction"--the purchase of an option on the same security
with the same exercise price and expiration date as the option previously
written on any particular security. When the security is sold, the Fund effects
a closing purchase transaction so as to close out any existing option on that
security.
 
There are risks associated with such investments, including the following: (1)
the success of a hedging strategy may depend on the ability of the Advisor and
SubAdvisor to predict movements in the prices of individual securities,
fluctuations in markets and movements in interest rates; (2) there may be an
imperfect correlation between the movement in prices of securities held by the
Fund and the price of options; (3) there may not be a liquid secondary market
for options; and (4) while the Fund will receive a premium when it writes
covered call options, it may not participate fully in a rise in the market value
of the underlying security.
 
OPTIONS ON CURRENCIES--The Fund may purchase options and write covered call
options on foreign currencies (traded on U.S. and foreign exchanges or
over-the-counter markets) to manage the Fund's exposure to changes in dollar
exchange rates. Call options on foreign currency written by the Fund will be
"covered," which means that the Fund will own an equal amount of the underlying
foreign currency. With respect to put options on foreign currency written by the
Fund, the Fund will establish a segregated account with its Custodian consisting
of cash, U.S. government securities or other liquid high grade debt securities
in an amount equal to the amount the Fund would be required to pay upon exercise
of the put.
 
REPURCHASE AGREEMENTS--Agreements by which the Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement.
The Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if the Fund realizes a loss in the sale
of the collateral. The Fund will enter into repurchase agreements only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based on established guidelines. Repurchase agreements are
considered loans under the 1940 Act.
 
RULE 144A SECURITIES--Rule 144A securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
SECURITIES LENDING--In order to generate additional income, the Fund may lend
the securities in which it is invested pursuant to agreements requiring that the
loan be continuously secured by cash, securities of the U.S. Government or its
agencies or any combination of cash and such securities as collateral equal to
100% of the market value at all times of the loaned securities. The lending Fund
will continue to receive interest on the loaned securities while simultaneously
earning interest on the investment of cash collateral. Collateral is marked to
market daily to provide a level of collateral at least equal to the market value
of the loaned securities. There may be risks of delay in receiving additional
collateral should the borrower of the securities fail financially.

U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. government, are either backed by the full faith and
credit of the United States or supported by the issuing agencies' right to
borrow from the Treasury.
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of
receipts. The custodian arranges for the issuances of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is not secondary
market for such security.
 
WARRANTS--Securities that entitle the holder to buy a proportionate amount of
common stock at a specified price for a limited or unlimited period of time.
Warrants are often freely transferable and are traded on major stock exchanges.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company which provides a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about
Investment Class shares of the MONEY MARKET, TREASURY MONEY MARKET and
CALIFORNIA TAX FREE MONEY MARKET FUNDS (each a "Fund"). This summary is
qualified in its entirety by reference to the more detailed information provided
elsewhere in this Prospectus and in the Statement of Additional Information.
 
WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?  THE MONEY MARKET FUND seeks to
preserve principal value and maintain a high degree of liquidity while providing
current income. THE TREASURY MONEY MARKET FUND seeks to preserve principal value
and maintain a high degree of liquidity while providing current income. THE
CALIFORNIA TAX-FREE MONEY MARKET FUND seeks to preserve principal and maintain a
high degree of liquidity while providing current income exempt from federal and
California state personal income taxes. See "Investment Objectives."
 
WHAT ARE THE FUNDS' PERMITTED INVESTMENTS?  THE MONEY MARKET FUND invests in
obligations denominated in U.S. dollars, including commercial paper, bank
obligations, thrift and savings and loan obligations, short-term corporate
obligations, general U.S. Government obligations and repurchase agreements
involving such obligations, receipts evidencing ownership of component parts of
U.S. Treasury obligations and securities issued or guaranteed by foreign
branches of foreign banks and foreign commercial paper. THE TREASURY MONEY
MARKET FUND invests exclusively in direct obligations issued by the U.S.
Treasury, separately traded component parts of such obligations transferable
through the Federal book-entry system, and repurchase agreements involving such
obligations. THE CALIFORNIA TAX-FREE MONEY MARKET FUND invests in municipal
obligations of the State of California and its political subdivisions and
municipal obligations issued by territories or possessions of the United States.
See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUNDS?  Each Fund seeks to
maintain a net asset value of $1.00 per share. There can be no assurance that a
Fund will be able to maintain a net asset value of $1.00 per share on a
continuous basis. The California Tax-Free Money Market Fund concentrates its
investments in California municipal securities, and an investment in the Fund
therefore may be riskier than an investment in other types of money market
funds. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or instrumentalities of the securities in which any Fund invests guarantees only
the payment of principal and interest on the guaranteed security, and does not
guarantee the yield or value of the security or yield or value of shares of that
Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  State Street Bank and Trust Company
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Investment Class shares of the Trust (except for the Convertible
Securities, Government Securities, Emerging Growth, Blue Chip Growth and
International Equity Funds). See "Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment is $2,000 ($1,000 for IRAs). Shareholders must place
orders to purchase prior to 12:00 noon, Eastern time or orders to redeem prior
to 11:00 a.m., Eastern time for the California Tax-Free Money Market Fund, and
prior to 12:00 noon, Eastern time for the Money Market and Treasury Money Market
Funds on any Business Day. Otherwise the order will be effective the next
Business Day. In addition, effectiveness of a purchase is contingent on the
Custodian's receipt of Federal funds before 2:00 p.m., Eastern time. See
"Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  The net investment income (exclusive of short-term
capital gains) of the Funds is determined and declared on each Business Day as a
dividend for Shareholders of record as of the close of business on that day.
Dividends are paid monthly in additional shares unless the Shareholder elects to
take the payment in cash. See "Dividends."

(1) The Advisor has voluntarily agreed to waive fees to the extent necessary in
    order to limit Total Operating Expenses of the Treasury Money Market and
    California Tax-Free Money Market Funds. The Advisor reserves the right to
    terminate its waiver at any time in its sole discretion. Absent this fee
    waiver, the Advisory Fees would be .30% for each Fund.
(2) Absent voluntary fee waivers, 12b-1 Fees would be .40% of each Fund. The
    Distributor reserves the right to terminate its waiver at any time in its
    sole discretion.
(3) Absent fee waivers, "Total Operating Expenses" would be .90% for each of the
    Money Market Fund, Treasury Money Market Fund and California Tax-Free Money
    Market Fund. "Total Operating Expenses" of the California Tax-Free Money
    Market Fund have been restated to reflect current fees and fee waivers.

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Investment Class shares of the Trust's Money Market, Treasury Money
Market and California Tax-Free Money Market Funds (each a "Fund"). Information
regarding the Trust's other funds is contained in separate prospectuses that may
be obtained from the Trust's Distributor, SEI Financial Services Company, 680
East Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVES
 
THE MONEY MARKET FUND seeks to preserve principal value and maintain a high
degree of liquidity while providing current income.
 
THE TREASURY MONEY MARKET FUND seeks to preserve principal value and maintain a
high degree of liquidity while providing current income.
 
THE CALIFORNIA TAX-FREE MONEY MARKET FUND seeks to preserve principal and
maintain a high degree of liquidity while providing current income exempt from
federal and California state personal income taxes.
 
There can be no assurance that a Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
MONEY MARKET FUND
 
The Money Market Fund invests in obligations denominated in U.S. dollars
consisting of:
(i) commercial paper (including Section 4(2) Commercial Paper) issued by
domestic and foreign issuers rated at least A-1 by Standard & Poor's Corporation
("S&P") or Prime-1 by Moody's Investors Service ("Moody's") at the time of
investment or, if not rated, determined by the Advisor to be of comparable
quality; (ii) obligations (certificates of deposit, bank notes, time deposits,
and bankers' acceptances) of thrift institutions, savings and loans, U.S.
commercial banks (including foreign branches of such banks), and U.S. and
foreign branches of foreign banks, provided that such institutions (or, in the
case of a branch, the parent institution) have total assets of $1 billion or
more as shown on their last published financial statements at the time of
investment; (iii) short-term corporate obligations (including Rule 144A
Securities) with a remaining term of not more than 397 days of issuers with
commercial paper of comparable priority and security meeting the above ratings
criteria or determined by the Advisor to be of comparable quality; (iv)
obligations issued by the U.S. Government and backed by its full faith and
credit, and obligations issued or guaranteed as to principal and interest by the
agencies or instrumentalities of the U.S. Government (e.g., obligations issued
by Farmers Home Administration, Government National Mortgage Association,
Federal Farm Credit Bank and Federal Housing Administration); (v) receipts,
including TR's, TIGR's and CATS; (vi) repurchase agreements involving such
obligations; (vii) loan participations; (viii) readily-marketable securities
backed by company receivables, truck and auto loans, leases, and credit card
loans provided that such instruments satisfy the rating requirements described
above or are determined by the Advisor to be of comparable quality and (ix) U.S.
dollar denominated securities issued or guaranteed by foreign governments, their
political subdivisions, agencies or instrumentalities, and obligations of
supranational entities such as the World Bank and the Asian Development Bank;
provided that the Fund invests no more than 5% of its assets in any such
instrument and invests no more than 25% of its assets in such instruments in the
aggregate. The Advisor will determine that the
<PAGE>   115
 
 6
 
permitted investments present minimal credit risks in accordance with guidelines
established by the Trust's Board of Trustees.
 
The Fund may concentrate its investments in certain instruments issued by U.S.
banks, U.S. branches of foreign banks and foreign branches of U.S. banks, but
only so long as the investment risk associated with investing in foreign
branches of domestic banks is the same as that associated with investing in
instruments issued by the U.S. parent, in that the U.S. parent would be
unconditionally liable in the event that the foreign branch failed to pay.
 
The Fund may invest up to 5% of its total assets in loan participations issued
by a bank in the United States with assets exceeding $1 billion where the
underlying loan is made to a borrower in whose obligations the Fund may invest
and the underlying loan has a remaining maturity of one year or less.
 
TREASURY MONEY MARKET FUND
 
The Treasury Money Market Fund invests exclusively in direct obligations issued
by the U.S. Treasury, separately traded component parts of such obligations
transferable through the Federal book-entry system ("STRIPS"), and repurchase
agreements involving such obligations.
 
The Fund is limited to making investments and engaging in investment
transactions that are permissible for federal credit unions.
 
Guarantees of the Fund's portfolio securities by the U.S. Government or its
agencies or instrumentalities guarantee only the principal and interest on the
guaranteed securities, and do not guarantee the securities' yield or value or
the yield or value of the Fund's shares.
 
CALIFORNIA TAX-FREE MONEY MARKET FUND
 
As a matter of fundamental policy, at least 80% of the California Tax-Free Money
Market Fund's assets are invested in obligations which produce interest that, in
the opinion of bond counsel, is exempt from Federal income tax and California
state personal income tax. These include obligations issued by the State of
California and its political subdivisions or municipal authorities and
obligations issued by territories or possessions of the United States.
Qualifying obligations consist of municipal notes; municipal bonds; floating or
variable rate municipal obligations; tax-exempt commercial paper; and shares of
open-end investment companies with similar investment objectives and policies.
 
The Advisor may engage in "put" transactions. The Advisor has discretion to
invest up to 20% of the Fund's assets in taxable money market instruments
(including repurchase agreements), securities which have not been registered
under the Securities Act of 1933 (Rule 144A Securities and Section 4(2)
Commercial Paper), receipts (including TR's, TIGR's, and CATS), and securities
the interest income from which is subject to the alternative minimum tax. While
the Fund generally intends to be fully invested in tax-exempt securities, the
Advisor may leave a portion of the Fund's assets uninvested.
 
For temporary defensive purposes when the Advisor determines that market
conditions warrant, the Fund may invest up to 100% of its assets in municipal
obligations of other states or taxable money market instruments (including
repurchase agreements, U.S. Treasury securities and instruments of certain U.S.
commercial banks or savings and loan institutions). The Fund will not be
pursuing its investment objective to the extent that more than 20% of its assets
are so invested in taxable money market securities.
 
The Fund will invest in obligations which are rated or are issued by entities
with debt obligations rated, at the time of investment, in one of the two
highest rating categories by S&P, Moody's or Fitch Investors Service, Inc.
("Fitch"), or, if not rated, determined by the Advisor to be of comparable
quality.
 
Opinions relating to the validity of municipal securities and to the exemption
of interest thereon from Federal income tax (and, with respect to California
municipal securities, to the exemption of interest thereon from California state
personal
<PAGE>   116
 
 7
 
income tax) are rendered by bond counsel to the respective issuers at the time
of issuance. Neither the Fund nor its Adviser will review the proceedings
relating to the issuance of municipal securities or the bases for such opinions.
 
GENERAL INVESTMENT POLICIES
 
Each Fund intends to comply with Rule 2a-7 adopted by the Securities and
Exchange Commission ("SEC"), which Rule permits money market funds to use the
amortized cost method for calculating net asset value. The Rule imposes certain
quality, maturity and diversification restraints on investments by a Fund. Under
the Rule, a Fund will invest only in U.S. dollar denominated securities, will
maintain an average maturity on a dollar-weighted basis of 90 days or less, and
will acquire only "eligible securities" that present minimal credit risks and
have a maturity of 397 days or less. For a further discussion, see the
"Description of Permitted Investments."
 
Each Fund may enter into forward commitments, or purchase securities on a
when-issued basis. A Fund is permitted to invest in when-issued securities where
such purchases are for investment and not for leveraging purposes; however, a
Fund may sell these securities before the settlement date if it is deemed
advisable. No additional forward commitments will be made if more than 20% of a
Fund's net assets would be so committed.
 
Each Fund may engage in securities lending, and will limit such practice to
33 1/3% of its total assets.
 
Each Fund will limit its investment in illiquid securities to 10% of its net
assets.
 
For further information, see "Description of Permitted Investments."
 
ELIGIBILITY UNDER FEDERAL CREDIT
UNION ACT
 
Shares of the Treasury Money Market Fund (the Fund) are designed to qualify as
eligible investments for federally chartered credit unions pursuant to Section
107(7), 107(8) and 107(15) of the Federal Credit Union Act and Part 703 of the
National Credit Union Administration Rules and Regulations. The Fund will
continually monitor changes in the applicable laws, rules and regulations
governing eligible investments, including new investments, for federally
chartered credit unions and will take such action as may be necessary to assure
that the Fund's investments, and, therefore, shares of the Fund, continue to
qualify as eligible investments under the Federal Credit Union Act.
 
Sections 107(7), 107(8) and 107(15) of the Federal Credit Union Act set forth
those securities, deposits and other obligations in which federally chartered
credit unions may invest. The Fund's investments consist exclusively of assets
designed to qualify as eligible investments if owned directly by a federally
chartered credit union. Shares of the Fund may or may not qualify as eligible
investments for particular state chartered credit unions. Accordingly, the Fund
encourages, but does not require, each state chartered credit union to consult
qualified legal counsel concerning whether the Fund's shares are permissible
investments for that credit union. While the Advisor will assure that the Fund
follows investment policies set forth herein, the Fund cannot be responsible for
compliance by participating state chartered credit unions with limitations on
permissible investments to which they may be subject.
 
RISK FACTORS
 
It is a fundamental policy of each Fund to use its best efforts to maintain a
constant net asset value of $1.00 per share. There can be no assurance that a
Fund will be able to maintain a stable net asset value of $1.00 per share.
 
Foreign securities which the Money Market Fund may purchase involve risks that
are different from investments in securities of U.S. issuers. These risks may
include future unfavorable political and economic developments, possible
withholding taxes, seizure of foreign deposits, currency controls, interest
limitations or other government
<PAGE>   117
 
 8
 
restrictions which might affect payment of principal or interest. Additionally,
there may be less public information available about foreign issuers. Foreign
branches of foreign banks are not regulated by U.S. banking authorities, and
foreign issuers generally are not bound by accounting, auditing and financial
reporting standards comparable to U.S. issuers.
 
Certain risks are inherent in the California Tax-Free Money Market Fund's
concentrated investment in California municipal securities, which may make an
investment in the Fund riskier than an investment in other types of money market
funds. These risks result from (1) amendments to the California Constitution and
other statutes that limit the taxing and spending authority of California
government entities, (2) the general financial condition of the State of
California, and (3) a variety of California laws and regulations that may
affect, directly or indirectly, California municipal securities. The ability of
issuers to pay interest on, or repay principal of, California municipal
securities may be impaired as a result. A more complete description of these
risks is contained in the Statement of Additional Information.
 
INVESTMENT LIMITATIONS
 
1. The Money Market Fund and the Treasury Money Market Fund may not purchase
securities of any issuer (except securities issued or guaranteed by the United
States its agencies or instrumentalities and repurchase agreements involving
such securities) if as a result more than 5% of the total assets of the Fund
would be invested in the securities of such issuer. While this restriction
applies to 75% of each Fund's assets, the Money Market Fund and the Treasury
Money Market Fund have each adopted, in accordance with Rule 2a-7, a policy
providing that the 5% limitation shall apply to 100% of the Fund's assets,
provided, however, that each Fund may invest up to 25% of its assets in the
First Tier quality securities of a single issuer for up to three days. For
purposes of this limitation, loan participations are considered to be issued by
both the issuing bank and the underlying corporate borrower.
 
2. The California Tax-Free Money Market Fund may not purchase securities of any
issuer (except securities issued or guaranteed by the United States, its
agencies or instrumentalities) and repurchase agreements involving such
securities if as a result more than 5% of the total assets of the Fund would be
invested in the securities of such issuer.
 
3. Each Fund may not purchase any securities which would cause more than 25% of
its total assets to be invested in the securities of one or more issuers
conducting their principal business activities in the same industry, provided
that this limitation does not apply to investments in the obligations issued or
guaranteed by the U.S. Government or its agencies and instrumentalities and
repurchase agreements involving such securities, and provided further, that
utilities as a group will not be considered to be one industry, and wholly-owned
subsidiaries organized to finance the operations of their parent companies will
be considered to be in the same industry as their parent companies. For purposes
of this limitation, loan participations are considered to be issued by both the
issuing bank and the underlying corporate borrower, and supranational entities
are considered to be a separate industry. This limitation does not apply to
investments by the Money Market Fund in certain bank instruments. In addition,
this limitation applies only to the California Tax-Free Money Market Fund's
investments in taxable securities and securities issued or backed by the
revenues of non-governmental users.
 
4. Each Fund may not make loans, except that a Fund may (a) purchase or hold
debt instruments in accordance with its investment objective and policies; (b)
enter into repurchase agreements; and (c) engage in securities lending as
described in this Prospectus and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.

FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Funds. It is also a fundamental policy of each Fund
to use its best efforts to maintain a constant net asset value of $1.00 per
share. Fundamental policies cannot be changed with respect to a Fund without the
consent of a majority of the Fund's outstanding shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of each Fund and continuously reviews,
supervises and administers the Fund's investment program. The Advisor discharges
its responsibilities subject to the supervision of, and policies established by,
the Trustees of the Trust. The Trust's shares are not sponsored, endorsed or
guaranteed by, and do not constitute obligations or deposits of, the Advisor and
are not guaranteed by the FDIC or any other government agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .30% of the average daily net assets of each Fund. The Advisor
may from time to time voluntarily waive all or a portion of its fees in order to
limit the operating expenses of a Fund. Any such waiver is voluntary, and may be
terminated at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, the Money Market, Treasury Money
Market and California Tax-Free Money Market Funds paid Union Bank, predecessor
of the Advisor, a fee of .30%, .25% and .10% of their average daily net assets,
respectively.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of each Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
Administration Agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses applicable to a Fund's
Investment Class shares. Any such waiver is voluntary, and may be terminated at
any time.
 
THE SHAREHOLDER SERVICING AGENT
 
State Street Bank and Trust Company serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Investment Class
shares of the Trust (except for the Convertible Securities, Government
Securities,
<PAGE>   119
 
 10
 
Emerging Growth, Blue Chip Growth and International Equity Funds).
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days written notice by either party, or upon assignment by the
Distributor.
 
The Investment Class shares have a distribution plan ("Investment Class Plan").
The Distribution Agreement and the Investment Class Plan provide that the
Investment Class shares of a Fund may bear the following distribution expenses:
(1) the cost of prospectuses, reports to Shareholders, sales literature and
other materials for potential investors; (2) advertising; and (3) expenses
incurred in connection with the promotion and sale of the Trust's shares
including the Distributor's expenses for travel, communication, and compensation
and benefits for sales personnel. In addition, the Trust pays the Distributor a
fee of up to .40% of a Fund's Investment Class shares average daily net assets,
of which a maximum of .25% may be used to compensate broker/dealers and service
providers which provide administrative and/or distribution services to
Investment Class Shareholders or to their other customers who beneficially own
Investment Class shares.
 
HOW TO PURCHASE SHARES
 
GENERAL INFORMATION
 
Purchases and redemptions of shares of the Funds may be made on days on which
both the New York Stock Exchange and the Federal Reserve wire system are open
for business ("Business Days"). The minimum initial investment in a Fund is
$2,000 ($1,000 for IRAs); however, the minimum investment may be waived in the
Distributor's discretion. Subsequent purchases must be at least $1,000 ($500 for
IRAs).
 
Purchase orders will be effective on the Business Day made if the Distributor
receives an order before 12:00 noon, Eastern time on such Business Day.
Otherwise, the purchase order will be effective the next Business Day.
Effectiveness of a purchase order on any Business Day is contingent on the
Custodian's receipt of Federal funds before 2:00 p.m. Eastern time on such day.
The purchase price is the net asset value per share, which is expected to remain
constant at $1.00. The net asset value per share is calculated as of 12:00 noon,
Eastern time, each Business Day based on the amortized cost method. The net
asset value per share of a Fund is determined by dividing the total value of its
investments and other assets, less any liabilities, by the total number of its
outstanding shares. The Trust reserves the right to reject a purchase order when
the Distributor determines that it is not in the best interest of the Trust
and/or Shareholder(s).
 
Shares of the Funds are offered only to residents of states in which the shares
are eligible for purchase.
 
HOW TO PURCHASE BY MAIL
 
You may purchase shares of a Fund by completing and signing an Account
Application form and mailing it, along with a check (or other negotiable bank
instrument or money order) payable to "Stepstone Funds (Fund Name)," to the
Transfer Agent at P.O. Box 8416, Boston, Massachusetts 02266-8416. All purchases
made by check should be in U.S. dollars and made payable to the "Stepstone Funds
(Fund Name)." Third party checks, credit card checks and cash will not be
accepted. You may purchase more shares at any time by mailing payment also to
the Transfer Agent at the above address. Orders placed by mail will be executed
on receipt of your payment. If your check does not clear, your purchase will be
canceled and you could be liable for any losses or fees incurred.
<PAGE>   120
 
 11
 
You may obtain Account Application forms by calling the Distributor at
1-800-734-2922.
 
HOW TO PURCHASE BY WIRE
 
You may purchase shares by wiring Federal funds, provided that your Account
Application has been previously received. You must wire funds to the Transfer
Agent and the wire instructions must include your account number. You must call
the Transfer Agent at 1-800-734-2922 before wiring any funds. An order to
purchase shares by Federal funds wire will be deemed to have been received by
the Fund on the Business Day of the wire; provided that the shareholder wires
funds to the Transfer Agent prior to 4:00 p.m., Eastern time. If the Transfer
Agent does not receive the wire by 4:00 p.m., Eastern time, the order will be
executed on the next Business Day.
 
HOW TO PURCHASE THROUGH AN AUTOMATIC
INVESTMENT PLAN ("AIP")
 
You may arrange for periodic additional investments in the Funds through
automatic deductions by Automated Clearing House ("ACH") from a checking account
by completing this section in the Account Application form. The minimum
pre-authorized investment amount is $100 per month. The AIP is available only
for additional investments to an existing account.
 
HOW TO PURCHASE THROUGH FINANCIAL INSTITUTIONS
 
Shares may be purchased through financial institutions, including the Adviser,
that provide distribution assistance or shareholder services. Shares purchased
by persons ("Customers") through financial institutions may be held of record by
the financial institution. Financial institutions may impose an earlier cut-off
time for receipt of purchase orders directed through them to allow for
processing and transmittal of these orders to the Transfer Agent for
effectiveness the same day. Customers should contact their financial institution
for information as to that institution's procedures for transmitting purchase,
exchange or redemption orders to the Trust.
 
Customers who desire to transfer the registration of shares beneficially owned
by them but held of record by a financial institution should contact the
institution to accomplish such change.
 
Depending upon the terms of a particular Customer account, a financial
institution may charge a Customer account fees. Information concerning these
services and any charges will be provided to the Customer by the financial
institution.
 
REDEMPTION OF SHARES
 
You may redeem your shares without charge on any Business Day. There is,
however, a $15 charge for wiring redemption proceeds to a shareholder's
designated account. Shares may be redeemed by mail, by telephone or through a
pre-arranged systematic withdrawal plan. Investors who own shares held by a
financial institution should contact that institution for information on how to
redeem shares.
 
BY MAIL
 
A written request for redemption must be received by the Transfer Agent, P.O.
Box 8416, Boston, Massachusetts 02266-8416 in order to constitute a valid
redemption request.
 
If the redemption request exceeds $5,000, or if the request directs the proceeds
to be sent or wired to an address different from that of record, the Transfer
Agent may require that the signature on the written redemption request be
guaranteed. You should be able to obtain a signature guarantee from a bank,
broker, dealer, credit union, securities exchange or association, clearing
agency or savings association. Notaries public cannot guarantee signatures. The
signature guarantee requirement will be waived if all of the following
conditions apply: (1) the redemption is for not more than $5,000 worth of
shares, (2) the redemption check is payable to the shareholder(s) of record, and
(3) the redemption check is mailed to the shareholders(s) at his or her address
of record.
<PAGE>   121
 
 12
 
BY TELEPHONE
 
You may redeem your shares by calling the Transfer Agent at 1-800-734-2922.
Under most circumstances, payments will be transmitted on the next Business Day
following receipt of a valid request for redemption. You may have the proceeds
mailed to your address or wired to a commercial bank account previously
designated on your Account Application. There is no charge for having redemption
proceeds mailed to you, but there is a $15 charge for wiring redemption
proceeds.
 
You may request a wire redemption for redemptions in excess of $500 by calling
the Transfer Agent at 1-800-734-2922 who will deduct a wire charge of $15 from
the amount of the wire redemption. Shares cannot be redeemed by Federal Reserve
wire on Federal holidays restricting wire transfers.
 
Neither the Transfer Agent nor the Trust will be responsible for any loss,
liability, cost or expense for acting upon wire or telephone instructions that
it reasonably believes to be genuine. The Trust and Transfer Agent will each
employ reasonable procedures to confirm that instructions communicated by
telephone are genuine. Such procedures may include taping of telephone
conversations.
 
If market conditions are extraordinarily active or other extraordinary
circumstance exist, and you experience difficulties placing redemption orders by
telephone, you may consider placing your order by mail.
 
SYSTEMATIC WITHDRAWAL PLAN ("SWP")
 
The Funds offer a Systematic Withdrawal Plan ("SWP"), which you may use to
receive regular distributions from your account. Upon commencement of the SWP,
your account must have a current net asset value of $5,000 or more. You may
elect to receive automatic payments via check or ACH of $100 or more on a
monthly, quarterly, semi-annual or annual basis. You may arrange to receive
regular distributions from your account via check or ACH by completing this
section in the Account Application form.
 
To participate in the SWP, you must have your dividends automatically
reinvested. You should realize that if your automatic withdrawals exceed income
dividends, your invested principal in the account will be depleted. Thus,
depending on the frequency and amounts of the withdrawal payments and/or any
fluctuations in the net asset value per share, your original investment could be
exhausted entirely. You may change or cancel the SWP at any time on written
notice to the Transfer Agent. The Transfer Agent may require that the signature
on the written notice be guaranteed.
 
OTHER INFORMATION REGARDING REDEMPTIONS
 
The Trust is required to redeem for cash all full and fractional shares of the
Trust. The redemption price is the net asset value per share of a Fund (normally
$1.00 per share).
 
Redemption orders may be made any time before 11:00 a.m., Eastern time for the
California Tax-Free Money Market Fund and 12:00 noon, Eastern time for the Money
Market and Treasury Money Market Fund in order to receive that day's redemption
price (i.e. the next determined net asset value per share). For redemption
orders received before 12:00 noon, Eastern time, payment will be made the same
day by transfer of federal funds. Otherwise, payment will be made on the next
Business Day. Redeemed shares are entitled to dividends declared the day the
redemption order is effective.
 
Payment to shareholders for shares redeemed will be made within seven days after
the Transfer Agent receives the valid redemption request. At various times,
however, a Fund may be requested to redeem shares for which it has not yet
received good payment; collection of payment may take ten or more days. In such
circumstances, the redemption request will be rejected by the Fund. Once a Fund
has received good payment for the shares a shareholder may submit another
request for redemption.
<PAGE>   122

Due to the relatively high costs of handling small investments, each Fund
reserves the right to redeem your shares at net asset value, if, your account in
any Fund has a value of less than the minimum initial purchase amount.
Accordingly, if you purchase shares of any Fund in only the minimum investment
amount, you may be subject to involuntary redemption if you redeem any shares.
Before any Fund exercises its right to redeem such shares, you will be given
notice that the value of the shares in your account is less than the minimum
amount and will be allowed 60 days to make an additional investment in such Fund
in an amount which will increase the value of the account to at least the
minimum amount.
 
COMPUTATION OF YIELD
 
From time to time a Fund advertises its "current yield" and "effective compound
yield." Both yield figures are based on historical earnings and are not intended
to indicate future performance. The "current yield" of the Fund refers to the
income generated by an investment in the Fund 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 "effective yield" is calculated similarly but,
when annualized, the income earned by an investment in the Fund is assumed to be
reinvested. The "effective yield" will typically be slightly higher than the
"current yield" because of the compounding effect of this assumed reinvestment.
The California Tax-Free Money Market Fund may also advertise tax equivalent
yields.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to Investment Class shares.
 
The yield of each Fund will fluctuate, and the annualization of a week's
dividend is not a representation by the Trust as to what an investment in the
Fund will actually yield in the future.
 
Each Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Funds may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Funds may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios,
and could include the value of a hypothetical investment in any of the capital
markets. The Funds may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Funds may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark, while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
TAXES
 
The following summary of federal and California income tax consequences is based
on current tax laws and regulations, which may be changed by legislative,
judicial or administrative action. No attempt has been made to present a
detailed explanation of the federal, state, or local income tax treatment of a
Fund or its Shareholders. In addition, state and local income tax consequences
<PAGE>   123
 
 14
 
of an investment in a Fund may differ from federal tax consequences described
below. Accordingly, Shareholders are urged to consult their tax advisers
regarding specific questions as to federal, state and local income taxes.
Additional information concerning taxes is set forth in the Statement of
Additional Information.
 
TAX STATUS OF THE FUNDS:
 
Each Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. Each Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on that part of its net investment company taxable income and
net capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
Each Fund will distribute all of its net investment income (including net
short-term capital gain) and net capital gain to Shareholders. Dividends from
net investment company taxable income are taxable to Shareholders as ordinary
income (whether received in cash or in additional shares) to the extent of the
Fund's earnings and profits. Distributions of net capital gain also will not
qualify for the dividends-received deduction and will be taxable to Shareholders
as long-term capital gain regardless of how long the Shareholders have held
their shares and regardless of whether the distributions are received in cash or
in additional shares. Dividends and distributions of capital gain paid by a Fund
do not qualify for the dividends received deduction for corporate Shareholders.
Each Fund will provide annual reports to Shareholders of the federal income tax
status of all distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments, a
Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because each Fund distributes
all of its net investment income to its shareholders, a Fund may have to sell
portfolio securities to distribute such imputed income, which may occur at a
time when the Advisor would not have chosen to sell such securities and which
may result in a taxable gain or loss.
 
Dividends declared by a Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
The Funds intend to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Income received on direct U.S. obligations is exempt from tax at the state level
when received directly by a Fund, and may be exempt, depending on the state,
when received by a Shareholder as income dividends from a Fund provided certain
state-specific conditions are satisfied. Interest received on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. Each Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from a Fund is considered tax exempt in their
particular state.
 
Income derived by a Fund from obligations of foreign issuers may be subject to
foreign withholding taxes. The Money Market Fund will not be able to elect to
treat Shareholders as having paid their proportionate share of such foreign
taxes.
 
Each sale, exchange or redemption of Fund shares is a taxable event to the
Shareholder.

SPECIAL CONSIDERATIONS FOR THE CALIFORNIA TAX-FREE MONEY MARKET FUND
 
The California Tax-Free Money Market Fund will distribute all of its net
investment income (including net short-term capital gain) to Shareholders. If,
at the close of each quarter of its taxable year, at least 50% of the value of
the Fund's assets consists of obligations the interest on which is excludable
from gross income, the Fund may pay "exempt-interest dividends" to its
Shareholders. Those dividends constitute the portion of the aggregate dividends
as designated by the Fund, equal to the excess of the excludable interest over
certain amounts disallowed as deductions. Exempt-interest dividends are
excludable from a Shareholder's gross income for federal income tax purposes,
but may have certain collateral federal income tax consequences, as described in
the Statement of Additional Information.
 
Current federal tax law limits the types and volume of bonds qualifying for the
federal income tax exemption of interest, which may have an effect on the
ability of the Fund to purchase sufficient amounts of tax-exempt securities to
satisfy the Code's requirements for the payment of "exempt-interest" dividends.
 
Any dividends attributable to the Fund's taxable income will be taxable to
Shareholders as ordinary income (whether received in cash or in additional
shares) to the extent of the Fund's earnings and profits. None of the Fund's
distributions will qualify for the corporate dividends-received deduction.
 
Furthermore, entities or persons who are "substantial users" (or persons related
to "substantial users") of facilities financed by "private activity bonds" or
"industrial development bonds" should consult their tax advisors before
purchasing shares. (See the Statement of Additional Information.)
 
CALIFORNIA TAXES:
 
The Fund intends to qualify to pay dividends to Shareholders that are exempt
from California personal income tax ("California exempt-interest dividends").
The Fund will qualify to pay California exempt-interest dividends if (1) at the
close of each quarter of the Fund's taxable year, at least 50 percent of the
value of the Fund's total assets consists of obligations the interest on which
would be exempt from California personal income tax if the obligations were held
by an individual ("California Tax Exempt Obligations") and (2) the Fund
continues to qualify as a regulated investment company.
 
If the Fund qualifies to pay California exempt-interest dividends, dividends
distributed to Shareholders will be considered California exempt-interest
dividends (1) if they are designated as exempt-interest dividends by the Fund in
a written notice to Shareholders mailed within 60 days of the close of the
Fund's taxable year and (2) to the extent the interest received by the Fund
during the year on California Tax Exempt Obligations exceeds expenses of the
Fund that would be disallowed under California personal income tax law as
allocable to tax-exempt interest if the Fund were an individual. If the
aggregate dividends so designated exceed the amount that may be treated as
California exempt-interest dividends, only that percentage of each dividend
distribution equal to the ratio of aggregate California exempt-interest
dividends to aggregate dividends so designated will be treated as a California
exempt-interest dividend. The California Tax-Free Money Market Fund will notify
Shareholders of the amount of California exempt-interest dividends each year.
 
Corporations subject to California franchise tax that invest in the Fund may not
be entitled to exclude California exempt-interest dividends from income.
 
Dividend distributions that do not qualify for treatment as California
exempt-interest dividends will be taxable to Shareholders at ordinary income tax
rates for California personal income tax purposes to the extent of the Fund's
earnings and profits.
 
Interest on indebtedness incurred or continued by a Shareholder in connection
with the purchase of shares of the Fund will not be deductible for California
personal income tax purposes if the
<PAGE>   125
 
 16
 
Fund distributes California exempt-interest dividends.
 
The foregoing is a general, abbreviated summary of certain provisions of the
California Revenue and Taxation Code presently in effect as they directly govern
the taxation of Shareholders subject to California personal income tax. These
provisions are subject to change by legislative or administrative action, and
any such change may be retroactive with respect to Fund transactions.
Shareholders are advised to consult with their own tax advisors for more
detailed information concerning California tax matters.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate portfolios of shares and different classes of each fund. In
addition to the Fund, the Trust consists of the following funds: Growth Equity
Fund, Value Momentum Fund, Intermediate-Term Bond Fund, Limited Maturity
Government Fund, Balanced Fund, Blue Chip Growth Fund, Emerging Growth Fund,
Convertible Securities Fund, Government Securities Fund, California Intermediate
Tax-Free Bond Fund, and International Equity Fund. All consideration received by
the Trust for shares of any fund and all assets of such fund belong to that fund
and would be subject to liabilities related thereto. The Trust reserves the
right to create and issue shares of additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses. Please refer to "Financial Highlights" in this prospectus
for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings, but approval will be sought for certain changes in the
operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon the written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate
assistance and information to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. This Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to Stepstone Funds, P.O. Box 8416,
Boston, Massachusetts 02266-8416.
 
DIVIDENDS
 
The net investment income (exclusive of net short-term capital gain) of each
Fund is determined and declared on each business day as a dividend for
Shareholders of record as of the close of business on that day. Dividends are
paid by the Fund in
<PAGE>   126
 
 17
 
additional shares, unless the Shareholder has elected to take such payment in
cash, on the first business day of each month. Shareholders may change their
election by providing written notice to the Administrator at least 15 days prior
to the change.
 
The dividends payable on the Investment Class shares will typically be lower
than the dividends payable on the Institutional Class shares because of the
distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank NA., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Funds:
 
ASSET-BACKED SECURITIES (NON-MORTGAGE)--Instruments secured by company
receivables, truck and auto loans, leases, and credit card receivables. Such
securities are generally issued as pass-through certificates, which represent
undivided fractional ownership interests in the underlying pools of assets. Such
securities also may be debt instruments, which are also known as collateralized
obligations and are generally issued as the debt of a special purpose entity,
such as a trust, organized solely for purpose of owning such assets and issuing
such debt. The purchase of non-mortgage asset-backed securities raises risk
considerations peculiar to the financing of the instruments underlying such
securities. Asset-backed securities entail prepayment risk, which may vary
depending on the type of asset.
 
BANKERS' ACCEPTANCES--Bills of exchange or time drafts drawn on and accepted by
commercial banks. They are used by corporations to finance the shipment and
storage of goods and to furnish dollar exchange. Maturities are generally six
months or less.
 
CERTIFICATES OF DEPOSIT--Negotiable interest-bearing instruments with a specific
maturity. Certificates of deposit are issued by banks and savings and loan
institutions in exchange for the deposit of funds and normally can be traded in
the secondary market, prior to maturity.
 
COMMERCIAL PAPER--Unsecured short-term promissory notes issued by corporations
and other entities. Maturities on these issues vary from a few days to nine
months. Purchase of such instruments involves a risk of default by the issuer.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
LOAN PARTICIPATIONS--Interests in loans to U.S. corporations (i.e., borrowers)
administered by the lending bank or agent for a syndicate of lending banks, and
sold by the lending bank or syndicate member ("intermediary bank"). Because the
intermediary bank does not guarantee a loan participation in any way, a loan
participation is subject to the credit risks generally associated with the
underlying corporate borrower. In addition, in the event the underlying
corporate borrower fails to pay principal and interest when due, the Fund may be
subject to delays, expenses and risks that are greater than those that would
have been involved if the Fund had purchased a direct
<PAGE>   127
 
 18
 
obligation (such as commercial paper) of such borrower. Moreover, the purchasing
Fund may be regarded as a creditor of the intermediary bank (rather than of the
underlying corporate borrower), making it subject to the risk that the issuing
bank may become insolvent. Further, in the event of the bankruptcy or insolvency
of the corporate borrower, a loan participation may be subject to certain
defenses that can be asserted by such borrower as a result of improper conduct
by the issuing bank. The secondary market, if any, for these loan participations
is limited, and any such participation purchased by the Fund may be regarded as
illiquid.
 
MUNICIPAL BONDS--Obligations issued by or on behalf of governments and political
sub-divisions thereof, including private activity bonds. The payment of the
principal and interest on such bonds is dependent solely on the ability of the
facility's user to meet its financial obligations and the pledge, if any, of
real and personal property so financed as security for such payment.
 
MUNICIPAL NOTES--Instruments issued by or on behalf of governments and political
sub-divisions thereof, and consist of general obligation notes, tax anticipation
notes, revenue anticipation notes, bond anticipation notes, certificates of
indebtedness, demand notes and construction loan notes.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
REPURCHASE AGREEMENTS--Agreements by which a Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. A Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement. A
Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if a Fund realizes a loss on the sale of
the collateral. A Fund will enter into repurchase agreements only with financial
institutions deemed to present minimal risk of bankruptcy during the term of the
agreement based on established guidelines. Repurchase agreements are considered
loans under the 1940 Act.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date, and no interest
accrues to a Fund before settlement. These securities are subject to market
fluctuation due to changes, real or anticipated, in market interest rates and
the public's perception of the creditworthiness of the issuer, and will have the
effect of leveraging the Fund's assets. Purchasing securities on a forward
commitment or when-issued basis when a Fund is fully or almost fully invested
may result in greater potential fluctuation in the value of a Fund's net asset
value per share. The purchasing Fund will establish one or more segregated
accounts with the Custodian, and will maintain liquid, high grade assets in an
amount at least equal in value to the Fund's commitments to purchase when-issued
securities.
 
SECURITIES LENDING--In order to generate additional income, each Fund may lend
the securities in which it is invested pursuant to agreements requiring that the
loan be continuously secured by cash, securities of the U.S. Government or its
agencies or any combination of cash and such securities as collateral equal to
100% of the market value at all times of the loaned securities. The lending Fund
will continue to receive interest on the loaned securities while simultaneously
earning interest on the investment of cash collateral. Collateral is marked to
market daily to provide a level of collateral at least equal to the value of the
loaned securities. There may be
<PAGE>   128
 
 19
 
risks of delay in receiving additional collateral or risks of delay in recovery
of the securities or even loss of rights in the collateral should the borrower
of the securities fail financially.
 
TAX-EXEMPT COMMERCIAL PAPER-- Commercial paper issued by governments and
political sub-divisions.
 
SECURITIES SUBJECT TO A PUT FEATURE--A "put" feature permits a Fund to sell a
security at a fixed price prior to maturity. The underlying securities subject
to a put may be sold at any time at the market rates. However, unless the put
was an integral part of the security as originally issued, it may not be
marketable or assignable. Generally, a premium is paid for a put feature or a
put feature is purchased separately which results in a lower yield than would
otherwise be available for the same securities.
 
TIME DEPOSITS--Non-negotiable receipts issued by U.S. or foreign banks in
exchange for the deposit of funds. Like certificates of deposit, they earn a
specified rate of interest over a definite period of time; however, they cannot
be traded in the secondary market. Time deposits with a withdrawal penalty are
considered to be illiquid securities.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the Federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks or brokerage firms and are
created by depositing Treasury notes and Treasury bonds into a special account
at a custodian bank. The custodian holds the interest and principal payments for
the benefit of the registered owners of the certificates or receipts. The
custodian arranges for the issuance of the certificates or receipts evidencing
ownership and maintains the register. Receipts include "Treasury Receipts"
("TR's"), "Treasury Investment Growth Receipts" ("TIGR's") and "Certificates of
Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and CATS are sold as zero
coupon securities, which means that they are sold at a substantial discount and
redeemed at face value at their maturity date without interim cash payments of
interest or principal. This discount is accreted over the life of the security,
and such accretion will constitute the income earned on the security for both
accounting and tax purposes. Because of these features, such securities may be
subject to greater interest rate volatility than interest paying securities. See
also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.
 
RESTRAINTS ON INVESTMENTS BY MONEY MARKET FUNDS
 
Investments by the Funds are subject to limitations imposed under regulations
adopted by the SEC.
<PAGE>   129
 
 20
 
These regulations generally require money market funds to acquire only U.S.
dollar denominated obligations maturing in 397 days or less and to maintain a
dollar-weighted average portfolio maturity of 90 days or less. In addition, the
Funds may acquire only obligations that present minimal credit risks and that
are "eligible securities," which means they are (i) rated, at the time of
investment, by at least two nationally recognized statistical rating
organizations (one if it is the only organization rating such obligation) in the
highest short-term rating category or, if unrated, determined to be of
comparable quality (a "first tier security"), or (ii) rated according to the
foregoing criteria in the second highest short-term rating category or, if
unrated, determined to be of comparable quality ("second tier security"). A
security is not considered to be unrated if its issuer has outstanding
obligations of comparable priority and security that have a short-term-rating.
In determining whether obligations are eligible securities, the rating of the
issuer's commercial paper, if any, is used for the above tests. Investments by
the Money Market Fund in second tier securities are subject to the further
constraints that (i) no more than 5% of the Fund's assets may be invested in
such securities in the aggregate, and (ii) any investment in such securities of
one issuer is limited to the greater of 1% of the Fund's total assets or $1
million. In addition, the Fund may invest up to 25% of its total assets in the
first tier securities of a single issuer for three business days.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Investment Class shares of the GOVERNMENT SECURITIES FUND, INTERMEDIATE-TERM
BOND FUND (each a "Fund"). This summary is qualified in its entirety by
reference to the more detailed information provided elsewhere in this Prospectus
and in the Statement of Additional Information.
 
WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?  THE INTERMEDIATE-TERM BOND FUND
seeks to provide total return. THE GOVERNMENT SECURITIES FUND seeks to achieve
total return consistent with the preservation of capital by investing in a
diversified portfolio of obligations issued or guaranteed by the U.S. government
or its agencies or instrumentalities. See "Investment Objectives."
 
WHAT ARE THE FUNDS' PERMITTED INVESTMENTS?  THE INTERMEDIATE-TERM BOND FUND
invests primarily in debt instruments. THE GOVERNMENT SECURITIES FUND invests
primarily in debt obligations issued or guaranteed by the U.S. government or its
agencies or instrumentalities, including mortgage-backed securities issued or
guaranteed by U.S. government agencies. See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUNDS?  The investment
policies of each Fund entail certain risks and considerations of which an
investor should be aware. The market value of a Fund's fixed income investments
will change in response to interest rate changes and other factors. During
periods of falling interest rates, the value of outstanding fixed income
securities generally rise. Conversely, during periods of rising interest rates,
the values of such securities generally decline. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE SUBADVISOR?  Bank of Tokyo-Mitsubishi Trust Company serves as the
SubAdvisor to the Government Securities Fund. See "The SubAdvisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  State Street Bank and Trust Company
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Investment Class shares of the Trust (except for the Convertible
Securities, Government Securities, Emerging Growth, Blue Chip Growth and
International Equity Funds). SEI Financial Management Corporation serves as
transfer agent, dividend disbursing agent, and shareholder servicing agent for
the Institutional and Cash Sweep Class shares of the Trust and for the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment in the Fund's Investment Class is $2,000 ($1,000 for
IRAs). A purchase order will be effective if the Distributor receives an order
prior to 4:00 p.m., Eastern time. Purchase orders for shares will be executed at
a per share price equal to the asset value next determined after the purchase
order is effective (plus any applicable sales charge). Redemption orders must be
placed prior to 4:00 p.m., Eastern time on any Business Day for the order to be
effective that day. See "Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of each Fund is distributed in the form of monthly
dividends to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF A FUND AND SHOULD NOT
BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES MAY
BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist the
investor in understanding the various costs and expenses that may be directly or

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Investment Class shares of the Trust's Government Securities and
Intermediate-Term Bond Funds (each a "Fund"). Information regarding the Trust's
other funds is contained in separate prospectuses that may be obtained from the
Trust's Distributor, SEI Financial Services Company, 680 East Swedesford Road,
Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVES
 
THE INTERMEDIATE-TERM BOND FUND seeks to provide total return.
 
THE GOVERNMENT SECURITIES FUND seeks to achieve total return consistent with the
preservation of capital by investing in a diversified portfolio of obligations
issued or guaranteed by the U.S. government or its agencies or
instrumentalities.
 
There can be no assurance that a Fund will meet its investment objective.
 
INVESTMENT POLICIES
 
INTERMEDIATE-TERM BOND FUND
 
Under normal market conditions, at least 65% of the Intermediate-Term Bond
Fund's assets will be invested in debt instruments. Such debt instruments shall
include corporate bonds and debentures rated AAA, AA, A, or BBB by Standard &
Poor's Corporation ("S&P") or Aaa, Aa, A, or Baa by Moody's Investors Service
("Moody's") or determined by the Advisor to be of comparable quality at the time
of purchase; Yankee Bonds and Eurodollar instruments, obligations issued by the
U.S. Government and its agencies and instrumentalities (such as Government
National Mortgage Association ("GNMA") securities); mortgage-backed securities,
including privately issued mortgage-backed securities; readily-marketable
asset-backed securities; securities issued or guaranteed by foreign governments,
their political subdivisions, agencies or instrumentalities; and obligations of
supranational entities such as the World Bank and the Asian Development Bank.
The remainder of the Fund's assets may be invested in money market instruments
and in cash. The dollar-weighted average portfolio maturity of the Fund will be
from three to ten years.
 
The portfolio turnover rate for the Intermediate-Term Bond Fund for the fiscal
year ended January 31, 1996 was 147%. This rate of portfolio turnover may result
in higher brokerage execution costs and higher levels of capital gains.
 
GOVERNMENT SECURITIES FUND
 
Under normal market conditions, the Government Securities Fund will invest at
least 80% of its assets in obligations issued or guaranteed by the U.S.
government or its agencies or instrumentalities, including mortgage-backed
securities issued or guaranteed by U.S. government agencies such as GNMA, the
Federal National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage
Corporation ("FHLMC"), and repurchase agreements backed by such securities. The
Fund may invest any remaining assets in corporate bonds that carry a rating of
Baa or better by Moody's or BBB or better by S&P, or that are deemed by the
SubAdvisor to be of comparable quality; Yankee Bonds, including sovereign,
supranational and Canadian bonds; shares of other investment companies with
similar investment objectives; commercial paper; money market funds; privately
issued mortgage-backed and other readily-marketable asset-backed securities; and
money market instruments and cash.
 
The SubAdvisor will seek to enhance the yield of the Fund by taking advantage of
yield disparities or other factors that occur in the government securities and
money markets. The Fund may dispose of any security prior to its maturity if
such
<PAGE>   136
 
 6
 
disposition and reinvestment of the proceeds are expected to enhance its yield
consistent with the SubAdvisor's judgment as to a desirable maturity structure
or if such disposition is believed to be advisable due to other circumstances or
considerations. The Fund will seek to achieve capital gains by taking advantage
of price appreciation caused by interest rate and credit quality changes.
 
The Fund may invest in futures and options on futures for the purpose of
achieving the Fund's objectives and for adjusting portfolio duration. The Fund
may invest in futures and related options based on any type of security or index
traded on U.S. or foreign exchanges or over the counter, as long as the
underlying security, or securities represented by an index, are permitted
investments of the Fund. The Fund may enter into futures contracts and options
on futures only to the extent that obligations under such contracts or
transactions represent not more than 10% of the Fund's assets.
 
The portfolio turnover rate for the Government Securities Fund for the fiscal
year ended January 31, 1996 was 239%. This rate of portfolio turnover may result
in higher brokerage execution costs and higher levels of capital gains.
 
GENERAL INVESTMENT POLICIES
 
Mortgage-backed securities purchased by the Funds will be issued or guaranteed
as to payment of principal and interest by the U.S. government or its agencies
or instrumentalities or, if issued by private issuers, rated in one of the two
highest rating categories by a nationally recognized rating agency. The
principal governmental issuers or guarantors of mortgage-backed securities are
GNMA, FNMA, and FHLMC. Obligations of GNMA are backed by the full faith and
credit of the United States Government, while obligations of FNMA and FHLMC are
supported by the credit of the respective agency only. The Funds may purchase
mortgage-backed securities that are backed or collateralized by fixed,
adjustable or floating rate mortgages.
 
For temporary defensive purposes during periods when the Advisor or SubAdvisor
determines that market conditions warrant, each Fund may invest up to 100% of
its assets in money market instruments consisting of securities issued or
guaranteed by the U.S. government, its agencies or instrumentalities, repurchase
agreements, receipts (including TR's, TIGR's and CATS), money market funds,
certificates of deposit, time deposits, bank master notes and bankers'
acceptances issued by banks having net assets of at least $1 billion as of the
end of their most recent fiscal year, commercial paper rated at least A-1 by S&P
or P-1 by Moody's, and in cash. A Fund will not be pursuing its investment
objective to the extent that more than a substantial portion of its assets are
invested in money market securities.
 
In the event that a security owned by a Fund is downgraded below the stated
ratings categories, the Advisor or SubAdvisor will take appropriate action with
regard to the security.
 
Each Fund will restrict its investment in illiquid securities to 15% of its net
assets.
 
Each Fund may engage in securities lending and will limit such practice to
33 1/3% of total assets.
 
Each Fund may purchase securities which have not been registered under the
Securities Act of 1933 (Rule 144A Securities).
 
Each Fund may purchase securities on a forward commitment or when-issued basis
where such purchases are for investment and not for leveraging purposes;
however, the Fund may sell these securities before the settlement date if it is
deemed advisable. No additional forward commitments will be made if more than
20% of a Fund's net assets would be so committed.
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
Each Fund's shares will fluctuate in value with the value of the underlying
securities in its portfolio. Changes in the value of a Fund's portfolio
securities will not affect cash received from ownership of such securities, but
will affect the Fund's net asset value.
 
Mortgage-backed securities that are not issued or guaranteed by the U.S.
government or its agencies
<PAGE>   137
 
 7
 
or instrumentalities, including securities nominally issued by a government
entity (such as the Resolution Trust Corporation), are not obligations of a
governmental entity, and thus may bear a greater risk of nonpayment. The timely
payment of principal and interest normally is supported, at least partially, by
various forms of insurance or guarantees. There can be no assurance, however,
that such credit enhancements will support fully the payment of principal and
interest on such obligations.
 
Securities rated BBB by S&P or Baa by Moody's are deemed by these rating
services to have some speculative characteristics and adverse economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than is the case with higher grade
bonds.
 
Each Fund may hold dollar denominated securities of foreign issuers which may
bear greater investment risks than those of U.S. domestic issuers. Such risks
include political and economic instability, expropriation of foreign deposits
and other restrictions which may adversely affect the payment of principal and
interest on such securities. See "Description of Permitted Investments."
 
INVESTMENT LIMITATIONS
 
Each Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the U.S. government or its agencies or instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of a Fund would be invested in the securities of such issuer. This
restriction applies to 75% of a Fund's assets.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies or instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objectives and policies, (b) enter into
repurchase agreements, and (c) engage in securities lending as described in this
Prospectus and in the Statement of Additional Income.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Funds. Fundamental policies cannot be changed with
respect to a Fund without the consent of the holders of a majority of the Fund's
outstanding shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of the Intermediate-Term Bond Fund and
continuously reviews, supervises and administers each Fund's investment program.
The Advisor discharges its responsibilities subject to the supervision of, and
policies established by, the Trustees of the Trust. The Trust's shares are not
sponsored, endorsed or guaranteed by, and do not constitute obligations or
deposits of, the Advisor and are not guaranteed by the FDIC or any other
governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .50% of the average daily net assets of the Government
Securities and Intermediate-Term Bond Funds. The Advisor may from time to time
waive all or a portion of its fee in order to limit the operating expenses of a
Fund. Any such waiver is voluntary
<PAGE>   138
 
 8
 
and may be terminated at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, predecessor of the
Advisor, was paid an advisory fee of .50% of the average daily net assets of the
Intermediate-Term Bond and the Government Securities Funds.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of each Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
James V. Atkinson has served as team leader of the Intermediate-Term Bond Fund
since 1991. Mr. Atkinson is a Vice President of the Advisor and has been with
the Advisor and its predecessor, Union Bank, since 1991. Mr. Atkinson was a
portfolio manager at The Boston Company from 1988 to 1990.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE SUBADVISOR
 
The Advisor and Bank of Tokyo-Mitsubishi Trust Company (the "SubAdvisor") have
entered into an investment subadvisory agreement relating to the Government
Securities Fund (the "Investment SubAdvisory Agreement"). Under the Investment
SubAdvisory Agreement, the SubAdvisor makes the day-to-day investment decisions
for the assets of the Government Securities Fund, subject to the supervision of,

out of the Advisor's fee, at an annual rate of .20% of the average daily net
assets of the Government Securities Fund. For the fiscal year ended January 31,
1996, Bank of Tokyo Trust Company, predecessor of the SubAdvisor, received .20%
of the average daily net assets of the Government Securities Fund.

THE SHAREHOLDER SERVICING AGENT
 
State Street Bank and Trust Company serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Investment Class
shares of the Trust (except for the Convertible Securities, Government

Distributor a fee of up to .40% of a Fund's Investment Class shares average
daily net assets, of which a maximum of .25% may be used to compensate
broker/dealers and service providers that provide administrative and/or
distribution services to Investment Class Shareholders or to their other
customers who beneficially own Investment Class shares.
 
HOW TO PURCHASE SHARES
 
GENERAL INFORMATION
 
Purchases and redemptions of shares of the Funds may be made on days on which
both the New York Stock Exchange and Federal Reserve wire system are open for
business ("Business Days"). The minimum initial investment in a Fund is $2,000
($1,000 for IRAs); however, the minimum investment may be waived at the
Distributor's discretion. All subsequent purchases must be in amounts of at
least $1,000 ($500 for IRAs).
 
Purchase orders for shares will be executed at a per share price equal to the
net asset value next determined after the receipt of the purchase order by the
Distributor (plus any applicable sales charge). The purchase price of shares of
a Fund is the net asset value next determined after a purchase order is received
and accepted by the Trust (plus a sales charge). The net asset value per share
of a Fund is determined by dividing the total market value of a Fund's
investments and other assets, less any liabilities, by the number of total
outstanding shares of a Fund. Net asset value per share is determined daily as
of 4:00 p.m.,
<PAGE>   140
 
 10
 
Eastern time, on any Business Day. Purchases will be made in full and fractional
shares of the Trust calculated to three decimal places. The Trust reserves the
right to reject a purchase order when the Distributor determines that it is not
in the best interest of the Trust and/or its Shareholders to accept such order.
 
Shares of the Funds are offered only to residents of states in which the shares
are eligible for purchase.
 
HOW TO PURCHASE BY MAIL
 
You may purchase shares of the Intermediate-Term Bond Fund by completing and
signing an Account Application form and mailing it, along with a check (or other
negotiable bank instrument or money order) payable to "Stepstone Funds (Fund
Name)," to the Transfer Agent at P.O. Box 8416, Boston, Massachusetts
02266-8416. All purchases made by check should be in U.S. dollars and made
payable to the "Stepstone Funds (Fund Name)." Third party checks, credit card
checks or cash will not be accepted. You may purchase more shares at any time by
mailing payment also to the Transfer Agent at the above address. Orders placed
by mail will be executed on receipt of your payment. If your check does not
clear, your purchase will be canceled and you could be liable for any losses or
fees incurred.
 
You may obtain Account Application Forms for the Intermediate-Term Bond Fund by
calling the Distributor at 1-800-734-2922.
 
HOW TO PURCHASE BY WIRE
 
You may purchase shares of the Intermediate-Term Bond Fund by wiring Federal
funds, provided that your Account Application has been previously received. You
must wire funds to the Transfer Agent and the wire instructions must include
your account number. You must call the Transfer Agent at 1-800-734-2922 before
wiring any funds. An order to purchase shares by Federal funds wire will be
deemed to have been received by the Fund on the Business Day of the wire;
provided that the shareholder wires funds to the Transfer Agent prior to 4:00
p.m., Eastern time, if the Transfer Agent does not receive the wire by 4:00
p.m., Eastern time, the order will be executed on the next Business Day.
 
HOW TO PURCHASE THROUGH AN AUTOMATIC
INVESTMENT PLAN ("AIP")
 
You may arrange for periodic additional investments in the Intermediate-Term
Bond Fund through automatic deductions by Automated Clearing House ("ACH") from
a checking account by completing this section in the Account Application form.
The minimum pre-authorized investment amount is $100 per month. The AIP is
available only for additional investments to an existing account.
 
HOW TO PURCHASE THROUGH FINANCIAL INSTITUTIONS
 
Shares of the Funds may be purchased through financial institutions, including
the Adviser, that provide distribution assistance or shareholder services.
Shares purchased by persons ("Customers") through financial institutions may be
held of record by the financial institution. Financial institutions may impose
an earlier cut-off time for receipt of purchase orders directed through them to
allow for processing and transmittal of these orders to the Transfer Agent for
effectiveness the same day. Customers should contact their financial institution
for information as to that institution's procedures for transmitting purchase,
exchange or redemption orders to the Trust.
 
Customers who desire to transfer the registration of shares beneficially owned
by them but held of record by a financial institution should contact the
institution to accomplish such change.
 
Depending upon the terms of a particular Customer account, a financial
institution may charge a Customer account fees. Information concerning these
services and any charges will be provided to the Customer by the financial
institution.

- ---------------
 
* A contingent deferred sales charge of 1.00% will be assessed against any
  proceeds of any redemption of such Investment Class shares prior to one year
  from date of purchase.
 
The commissions shown in the table apply to sales through authorized dealers and
brokers. Under certain circumstances, the Distributor may use its own funds to
compensate financial institutions and intermediaries in amounts that are
additional to the commissions shown above. In addition, the Distributor may,
from time to time and at its own expense, provide promotional incentives in the
form of cash or other compensation to certain financial institutions and
intermediaries whose registered representatives have sold or are expected to
sell significant amounts of the Investment Class shares of the Fund. Such other
compensation may take the form of payments for travel expenses, including
lodging, incurred in connection with trips taken by qualifying registered
representatives to places within or without the United States. Under certain
circumstances, commissions up to the amount of the entire sales charge may be
reallowed to dealers or brokers, who might then be deemed to be "underwriters"
under the Securities Act of 1933. Commission rates may vary among the Funds.
 
In calculating the sales charge rates applicable to current purchases of a
Fund's shares, a "single purchaser" is entitled to cumulate current purchases
with the net purchases of previously purchased shares of the Fund and other of
the Trust's funds (the "Eligible Funds") which are sold subject to a comparable
sales charge.
 
The term "single purchaser" refers to (i) an individual, (ii) an individual and
spouse purchasing shares of the Fund for their own account or for trust or
custodial accounts for their minor children, or (iii) a fiduciary purchasing for
any one trust, estate or fiduciary account, including employee benefit plans
created under Sections 401, 403(b) or 457 of the Internal Revenue Code of 1986,
as amended (the "Code"), including related plans of the same employer. To be
entitled to a reduced sales charge based upon shares already owned, the investor
must ask the Distributor for such entitlement at the time of purchase and
provide the account number(s) of the investor, the investor and spouse, and
their minor children, and give the age of such children. The Fund may amend or
terminate this right of accumulation at any time as to subsequent purchases.
 
LETTER OF INTENT.  By initially investing at least $2,000 and submitting a
Letter of Intent (the "Letter") to the Distributor, a "single purchaser" may
purchase shares of the Fund and the other Eligible Funds during a 13-month
period at the reduced sales charge rates applying to the aggregate amount of the
intended purchases stated in the Letter. The Letter may apply to purchases made
up to 90 days before the date of the Letter. To receive credit for such prior
purchases and later purchases benefitting from the Letter, the Shareholder must
notify the Transfer Agent at the time the Letter is submitted that there are
prior purchases that may apply, and, at the time of later purchases, notify the
Transfer Agent that such purchases are applicable under the Letter.
 
RIGHTS OF ACCUMULATION.  In calculating the sales charge rates applicable to
current purchases of Investment Class shares, a "single purchaser" is entitled
to cumulate current purchases with the current market value of previously
purchased Investment Class shares of the Funds sold subject to a comparable
sales charge.
 
To exercise your right of accumulation based upon shares you already own, you
must ask the Distributor for this reduced sales charge at the time of your
additional purchase and provide the account number(s) of the investor, as
applicable, the investor and spouse, and their minor children. The Funds may
amend or terminate this right of
<PAGE>   142
 
 12
 
accumulation at any time as to subsequent purchases.
 
WAIVER OF SALES LOAD.  No sales charge is imposed on Investment Class shares of
the Fund: (i) issued in plans of reorganization, such as mergers, asset
acquisitions and exchange offers, to which the Trust is a party; (ii) sold to
dealers or brokers that have a sales agreement with the Distributor, for their
own account or for retirement plans for their employees or sold to employees
(and their spouses) of dealers or brokers that certify to the Distributor at the
time of purchase that such purchase is for their own account (or for the benefit
of such employees' minor children); (iii) in aggregate purchases of $1 million
or more by tax-exempt organizations enumerated in Section 501(c) of the Code, or
employee benefit plans created under Sections 401, 403(b) or 457 of the Code;
(iv) sold to employees and families of the Advisor and its affiliates; (v) sold
to fiduciary accounts of the Advisor and its affiliates; or (vi) purchased with
proceeds from the recent redemption of shares of a mutual fund with similar
investment objectives and policies for which a sales charge was paid.
 
The waiver of the sales changes under clause (vi) applies only if the following
conditions are met: the purchase must be made within 60 days of the redemption;
the Distributor must be notified in writing by the investors, or his or her
agent, at the time a purchase is made; and a copy of the investor's account
statement showing such redemption must accompany such notice. The waiver policy
with respect to the purchase of shares through the use of proceeds from a recent
redemption above will not continue indefinitely and may be discontinued at any
time without notice. Investors should contact the Distributor to confirm
continued availability prior to initiating the procedures described in clause
(vi).
 
REDEMPTION OF SHARES
 
You may redeem your shares of the Intermediate-Term Bond Fund without charge on
any Business Day. There is, however, a $15 charge for wiring redemption proceeds
to a shareholder's designated account. Shares may be redeemed by mail, by
telephone or through a pre-arranged systematic withdrawal plan. Investors who
own shares held by a financial institution should contact that institution for
information on how to redeem shares.
 
BY MAIL
 
A written request for redemption of shares of the Intermediate-Term Bond Fund
must be received by the Transfer Agent, P.O. Box 8416, Boston, Massachusetts
02266-8416 in order to constitute a valid redemption request.
 
If the redemption request exceeds $5,000, or if the request directs the proceeds
to be sent or wired to an address different from that of record, the Transfer
Agent may require that the signature on the written redemption request be
guaranteed. You should be able to obtain a signature guarantee from a bank,
broker, dealer, credit union, securities exchange or association, clearing
agency or savings association. Notaries public cannot guarantee signatures. The
signature guarantee requirement will be waived if all of the following
conditions apply: (1) the redemption is for not more than $5,000 worth of
shares, (2) the redemption check is payable to the shareholder(s) of record, and
(3) the redemption check is mailed to the shareholder(s) at his or her address
of record.
 
BY TELEPHONE
 
You may redeem your shares of the Intermediate-Term Bond Fund by calling the
Transfer Agent at 1-800-734-2922. Under most circumstances, payments will be
transmitted on the next Business Day following receipt of a valid request or
redemption. You may have the proceeds mailed to your address or wired to a
commercial bank account previously designated on your Account Application. There
is no charge for having redemption proceeds mailed to you, but there is a $15
charge for wiring redemption proceeds.
 
You may request a wire redemption for redemptions of shares of the
Intermediate-Term Bond Fund in excess of $500 by calling the Transfer Agent at
1-800-734-2922 who will deduct a wire charge of $15 from the amount of the wire
redemption. Shares cannot be redeemed by Federal Reserve wire on Federal
holidays restricting wire transfers.
<PAGE>   143
 
 13
 
Neither the Transfer Agent nor the Trust will be responsible for any loss,
liability, cost or expense for acting upon wire or telephone instructions that
it reasonably believes to be genuine. The Trust and Transfer Agent will each
employ reasonable procedures to confirm that instructions, communicated by
telephone are genuine. Such procedures may include taping of telephone
conversations.
 
If market conditions are extraordinarily active or other extraordinary
circumstance exist, and you experience difficulties placing redemption orders by
telephone, you may consider placing your order by mail.
 
SYSTEMATIC WITHDRAWAL PLAN ("SWP")
 
The Intermediate-Term Bond Fund offers a Systematic Withdrawal Plan ("SWP"),
which you may use to receive regular distributions from you account. Upon
commencement of the SWP, your account must have a current net asset value of
$5,000 or more. You may elect to receive automatic payments via check or ACH of
$100 or more on a monthly, quarterly, semi-annual or annual basis. You may
arrange to receive regular distributions from your account via check or ACH by
completing this section in the Account Application form.
 
To participate in the SWP, you must have your dividends automatically
reinvested. You should realize that if your automatic withdrawals exceed income
dividends, your invested principal in the account will be depleted. Thus,
depending on the frequency and amounts of the withdrawal payments and/or any
fluctuations in the net asset value per share, your original investment could be
exhausted entirely. You may change or cancel the SWP at any time on written
notice to the Transfer Agent. The Transfer Agent may require that the signature
on the written notice be guaranteed.
 
It is generally not in your best interest to be participating in the SWP at the
same time that you are purchasing additional shares if you have to pay a sales
load in connection with such purchases.
 
OTHER INFORMATION REGARDING REDEMPTIONS.
 
Shareholders who desire to redeem shares of a Fund must place their redemption
orders prior to 4:00 p.m., Eastern time, on any Business Day for the order to be
accepted on that Business Day. The redemption price is the net asset value of a
Fund next determined after receipt by the Distributor of the redemption order.
Payment on redemption will be made as promptly as possible and, in any event,
within seven calendar days after the redemption order is received.
 
Payment to shareholders for shares redeemed will be made within seven days after
the Transfer Agent receives the valid redemption request. At various times,
however, a Fund may be requested to redeem shares for which it has not yet
received good payment; collection of payment may take ten or more days. In such
circumstances, the redemption request will be rejected by the Fund. Once a Fund
has received good payment for the shares a shareholder may submit another
request for redemption.
 
Due to the relatively high costs of handling small investments, each Fund
reserves the right to redeem your shares at net asset value, if, your account in
any Fund has a value of less than the minimum initial purchase amount.
Accordingly, if you purchase shares of any Fund in only the minimum investment
amount, you may be subject to involuntary redemption if you redeem any shares.
Before any Fund exercises its right to redeem such shares you will be given
notice that the value of the shares in your account is less than the minimum
amount and will be allowed 60 days to make an additional investment in such Fund
in an amount which will increase the value of the account to at least the
minimum amount.
 
PURCHASES BY EXCHANGE
 
As permitted pursuant to any rule, regulation or order promulgated by the
Securities and Exchange Commission, shareholders of Investment Class shares of
other Funds of the Trust that have similar sales charges may tender their shares
for those Funds for exchange into the number of shares (including fractional
shares) which have a value equal to the total net asset value of shares tendered
divided by the net asset value of Investment Class shares of the Fund next
determined after such order is received. Shares issued pursuant to this offer
will not be subject to this sales charge described above or any other
<PAGE>   144
 
 14
 
charge. The Fund may modify or terminate this exchange offer at any time upon 60
days' notice.
 
PERFORMANCE
 
From time to time, the Funds may advertise yield and total return. These figures
will be based on historical earnings and are not intended to indicate future
performance. The yield of a Fund refers to the annualized income generated by an
investment in the Fund over a specified 30-day period. The yield is calculated
by assuming that the same amount of income generated by the investment during
that period is generated in each 30-day period over one year and is shown as a
percentage of the investment.
 
The total return of a Fund refers to the average compounded rate of return to a
hypothetical investment for designated time periods (including, but not limited
to, the period from which the Fund commenced operations through the specified
date), assuming that the entire investment is redeemed at the end of each period
and assuming the reinvestment of all dividend and capital gain distributions.
The total return of a Fund may also be quoted as a dollar amount or on an
aggregate basis, an actual basis, without inclusion of any sales charge, or with
a reduced sales charge in advertisements distributed to investors entitled to a
reduced sales charge.
 
A Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long-term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial, or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local income tax treatment of a Fund or
its Shareholders. In addition, state and local tax consequences of an investment
in the Fund may differ from the federal income tax consequences described below.
Accordingly, Shareholders are urged to consult their tax advisers regarding
specific questions as to federal, state, and local income taxes. Additional
information concerning taxes is set forth in the Statement of Additional
Information.
 
TAX STATUS OF THE FUNDS:
 
Each Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. Each Fund intends to qualify for the
special tax treatment afforded regulated investment companies by the Internal
Revenue Code of 1986, as amended (the "Code"), so as to be relieved of federal
income tax on that part of its net investment company taxable income and net
capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
<PAGE>   145
 
 15
 
TAX STATUS OF DISTRIBUTIONS:
 
A Fund will distribute substantially all of its net investment income (including
net short-term capital gain) to Shareholders. Dividends from a Fund's net
investment company taxable income are taxable to Shareholders as ordinary income
(whether received in cash or in additional shares) to the extent of the Fund's
earnings and profits. Any net capital gains will be distributed at least
annually and will be taxed to Shareholders as long-term capital gains,
regardless of how long the Shareholder has held shares and regardless of whether
the distributions are received in cash or in additional shares. Dividends and
distributions of capital gain do not qualify for the dividends-received
deduction for corporate shareholders. Each Fund will provide annual reports to
Shareholders of the federal income tax status of all distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments, a
Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because each Fund distributes
all of its net investment income to Shareholders, a Fund may have to sell
portfolio securities to distribute such imputed income, which may occur at a
time when the Advisor or SubAdvisor would not have chosen to sell such
securities and which may result in a taxable gain or loss.
 
Investment income received directly by a Fund on direct U.S. obligations is
exempt from tax at the state level, and may be exempt, depending on the state,
when received by a Shareholder as income dividends from a Fund, provided certain
state-specific conditions are satisfied. Interest realized on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. Each Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from a Fund is considered tax exempt in their
particular state.
 
Dividends declared by a Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared if paid by the Fund any time during the following January.
 
The Funds intend to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Each sale, exchange, or redemption of Fund shares is a taxable event to the
Shareholder.
 
GENERAL INFORMATION

TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to that fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings of shareholders, but approval will be sought for certain changes
in the operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate

SHAREHOLDER INQUIRIES
 
Shareholder inquiries for the Intermediate-Term Bond Fund should be directed to
Stepstone Funds, P.O. Box 8416, Boston, Massachusetts 02266-8416. Shareholder
inquiries for the Government Securities Fund should be directed to the
Administrator, SEI Financial Management Corporation, 680 East Swedesford Road,
Wayne, Pennsylvania 19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of
the Fund is distributed in the form of monthly dividends to Shareholders of
record. Currently, capital gains of a Fund, if any, will be distributed at least
annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares, unless the Shareholder has elected to take
such payment in cash. Shareholders may change their election by providing
written notice to the Administrator at least 15 days prior to the distribution.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on the Investment Class shares will typically be lower
than the dividends payable on the Institutional Class shares because of the
distribution expenses charged on Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank, N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the Trust. The
Custodian holds cash, securities and other assets of the Trust as required by
the Investment Company Act of 1940, as amended (the "1940 Act").
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Funds:
 
ASSET-BACKED SECURITIES (NON-MORTGAGE)--Instruments secured by company
receivables, truck and auto loans, leases, and credit card receivables. Such
securities are generally issued as pass-through certificates, which represent
undivided fractional ownership interests in the underlying pools of assets. Such
<PAGE>   147
 
 17
 
securities also may be debt instruments, which are also known as collateralized
obligations and are generally issued as the debt of a special purpose entity,
such as a trust, organized solely for purpose of owning such assets and issuing
such debt. The purchase of non-mortgage asset-backed securities raises risk
considerations peculiar to the financing of the instruments underlying such
securities. Asset-backed securities entail prepayment risk, which may vary
depending on the type of asset, but is generally less than the prepayment risk
associated with mortgage-backed securities.
 
CORPORATE OR GOVERNMENT BONDS-- Interest-bearing or discounted corporate or
government securities that obligates the issuer to pay the bondholder a
specified sum of money, usually at specific intervals, and to repay the
principal amount of the loan at maturity. Bonds rated Baa or better by Moody's
or BBB or better by S&P are considered investment grade quality.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
FUTURES AND OPTIONS ON FUTURES--Some futures strategies, including selling
futures, buying puts and writing calls, reduce the Fund's exposure to price
fluctuations. Other strategies, including buying futures, writing puts and
buying calls, tend to increase market exposure. Futures and options may be
combined with each other in order to adjust the risk and return characteristics
of the overall portfolio.
 
Options and futures can be volatile instruments, and involve certain risks that,
if applied at an inappropriate time, could negatively impact the Fund's return.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality, dollar
denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial paper; and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and broker
dealers.
 
MORTGAGE-BACKED SECURITIES--Securities generally issued or guaranteed by U.S.
government agencies such as GNMA, FNMA, or FHLMC. GNMA mortgaged-backed
certificates are mortgage-backed securities of the modified pass-through type,
which means that both interest and principal payments (including prepayments)
are passed through monthly to the holder of the certificate. Each GNMA
certificate evidences an interest in a specific pool of mortgage loans insured
by the Federal Housing Administration or the Farmers Home Administration or
guaranteed by the Veterans Administration. FNMA, a federally-chartered and
stockholder-owned corporation, issues pass-through certificates which are
guaranteed as to payment of principal and interest by FNMA. FHLMC, a corporate
instrumentality of the United States, issues participation certificates which
represent an interest in mortgages held in FHLMC's portfolio. FHLMC guarantees
the timely payment of interest and the ultimate collection of principal.
Securities issued or guaranteed by FNMA and FHLMC are not backed by the full
faith and credit of the United States. There can be no assurance that the U.S.
government would provide financial support to FNMA or FHLMC if necessary in the
future.
 
Adjustable rate mortgage securities ("ARMs") are pass-through certificates
representing ownership interests in a pool of adjustable rate mortgages and the
resulting cash flow from those mortgages. Unlike conventional debt securities,
which provide for periodic (usually semi-annually) payments of interest and
payments of principal at maturity or on specified call dates, ARMs provide for
monthly payments based on a pro rata share of both periodic interest and
principal payments and
<PAGE>   148
 
 18
 
prepayments of principal on the underlying mortgage pool (less GNMA's, FNMA's,
or FHLMC's fees and any applicable loan servicing fees).
 
Collateralized mortgage obligations ("CMOs") are bonds generally issued by
single purpose, stand-alone finance subsidiaries or trusts established by
financial institutions, government agencies, investment banks, or other similar
institutions, and collateralized by pools of mortgage loans. Payments of
principal and interest on the collateral mortgages are used to pay debt service
on the CMO. In a CMO, a series of bonds or certificates is issued in multiple
classes. Each class of CMOs, often referred to as a "tranche," is issued at a
specific coupon rate and has a stated maturity or final distribution date. The
principal and interest payment on the underlying mortgages may be allocated
among the classes of CMOs in several ways. Typically, payments of principal,
including any prepayments, on the underlying mortgages would be applied to the
classes in the order of their respective stated maturities or final distribution
dates, so that no payment of principal will be made on CMOs of a class until all
CMOs of other classes having earlier stated maturities or final distribution
dates have been paid in full.
 
One or more classes of CMOs may have coupon rates that reset periodically based
on an index, such as the London Interbank Offered Rate ("LIBOR"). Each Fund may
purchase fixed, adjustable, or "floating" rate CMOs that are collateralized by
fixed rate or adjustable rate mortgages that are guaranteed as to payment of
principal and interest by an agency or instrumentality of the U.S. government or
are directly guaranteed as to payment of principal and interest by the issuer,
which guarantee is collateralized by U.S. government securities or are
collateralized by privately issued fixed rate or adjustable rate mortgages.
 
Real Estate Mortgage Investment Conduits ("REMICs") are private entities formed
for the purpose of holding a fixed pool of mortgages secured by an interest in
real property. REMICs are similar to CMOs in that they issue multiple classes of
securities.
 
REPURCHASE AGREEMENTS--Agreements by which a Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. A Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement. A
Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if the Fund realizes a loss on the sale
of the collateral. A Fund will enter into repurchase agreements only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based on established guidelines. Repurchase agreements are
considered loans under the 1940 Act.
 
RULE 144A SECURITIES -- Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of the Rule 144A Securities.
The Board of Trustees of the Trust has established guidelines and procedures to
be utilized to determine the liquidity of such securities.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date, and no interest
accrues to a Fund before settlement. These securities are subject to market
fluctuation due to changes, real or anticipated, in market interest rates and
the public's perception of the creditworthiness of the issuer, and will have the
effect of leveraging the Fund's assets. The Fund will establish one or more
segregated accounts with the Custodian, and the Fund will maintain liquid,
high-grade assets in an amount at least equal in value to the Fund's commitments
to purchase when-issued securities.
 
SECURITIES LENDING--In order to generate additional income, each Fund may lend
the securities in which it is invested pursuant to
<PAGE>   149
 
 19
 
agreements requiring that the loan be continuously secured by cash, securities
of the U.S. Government or its agencies or any combination of cash and such
securities as collateral equal to 100% of the market value at all times of the
loaned securities. The lending Fund will continue to receive interest on the
loaned securities while simultaneously earning interest on the investment of
cash collateral. Collateral is marked to market daily to provide a level of
collateral at least equal to the value of the loaned securities. There may be
risks of delay in receiving additional collateral or risks of delay in recovery
of the securities or even loss of rights in the collateral should the borrower
of the securities fail financially.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes, and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the Federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of such
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts includes
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than
interest-paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.
 
YANKEE BONDS--Dollar denominated securities issued by foreign-domiciled issuers
that obligate the issuer to pay the bondholder a specified sum of money, usually
semiannually, and to repay the principal amount of the loan at maturity.
Sovereign bonds are bonds issued by the governments of foreign countries.
Supranational bonds are those issued by supranational entities, such as the
World Bank and the European Investment Bank. Canadian bonds are bonds issued by
Canadian provinces.
 
SECURITIES OF FOREIGN ISSUERS--Securities issued by non-U.S. issuers. There may
be certain risks connected with investing in foreign securities, including risks
of adverse political and economic developments (including possible governmental
seizure or nationalization of assets), the possible imposition of exchange
controls or other governmental restrictions, including less uniformity in
accounting and reporting requirements, the possibility that there will be less
information on such securities and their issuers available to the public, the
difficulty of obtaining or enforcing court judgments abroad, restrictions on
foreign
<PAGE>   150
 
 20
 
investments in other jurisdictions, difficulties in effecting repatriation of
capital invested abroad, and difficulties in transaction settlements and the
effect of delay on shareholder equity. Foreign securities may be subject to
foreign taxes, which reduce yield, and may be less marketable than comparable
U.S. securities. A Fund may be affected favorably or unfavorably by changes in
the exchange rates or exchange control regulations between foreign currencies
and the U.S. dollar. Changes in foreign currency exchange rates may also affect
the value of dividends and interest earned, gains and losses realized on the
sale of securities and net investment income and gains, if any, distributed to
shareholders by a Fund. See "Risk Factors."

asset value next determined after the purchase order is effective (plus any
applicable sales charge). Redemption orders must be placed prior to 4:00 p.m.,
Eastern time on any Business Day for the order to be accepted that day. See
"Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income

subject to the same expenses, except there are no sales charges or distribution
costs. Additional information may be found under "The Administrator", "The
Advisor" and "The SubAdvisor."
 
The rules of the Securities and Exchange Commission require that the maximum
sales charge be reflected in the above table. However, certain investors may
qualify for reduced sales charges. See "Purchase and Redemption of Shares."

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Investment Class shares of the Trust's Convertible Securities Fund (the
"Fund"). Information regarding the Trust's other funds is contained in separate
prospectuses that may be obtained from the Trust's Distributor, SEI Financial
Services Company, 680 East Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVE
 
The Convertible Securities Fund seeks a high level of current income and capital
appreciation by investing in convertible securities.
 
There can be no assurance that the Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
Under normal market conditions, at least 65% of the Fund's assets will be
invested in convertible securities consisting of bonds, debentures, notes, and
preferred stocks convertible into common stock. In general, a convertible
security is a fixed-income security, such as a bond (which typically pays a
fixed annual rate of interest) or preferred stock (which typically pays a fixed
dividend), that may be converted at a stated price within a specified period of
time into a specified number of common stock of the issuing company or a
different company. A convertible security may be subject to redemption by the
issuer, but only after a particular date and under certain circumstances
(including a specified price) established upon issue. If a convertible security
held by the Fund is called for redemption, the Fund could be required to tender
it for redemption, convert it into the underlying common stock, or sell it to a
third party. Common stock received upon conversion will be sold when, in the
opinion of the SubAdvisor, it is advisable to do so.
 
Because of its conversion feature, the market value of convertible preferred
stock tends to move together with the market value of the underlying common
stock. As a result, the Fund's selection of convertible securities is based, to
a great extent, on the potential for capital appreciation that may exist in the
underlying common stocks. The value of convertible securities is also affected
by prevailing interest rates, the credit quality of the issuer, and any call
provisions. Investments in convertible securities generally entail less
volatility than investments in the common stocks of the same issuers.
Nevertheless, it is the fixed income component of these securities that is often
deemed by the ratings agencies to be high risk or speculative. The Fund may
invest less than 35% of its assets in convertible bonds rated lower than Baa by
Moody's Investors Service, Inc. ("Moody's") or BBB by Standard & Poor's
Corporation ("S&P") and as low as Caa by Moody's or CCC by S&P, which are
lower-quality, higher-yielding, high-risk debt securities (commonly known as
"junk bonds"). The Fund may also invest in unrated convertible securities which,
in the SubAdvisor's opinion, are of comparable quality to such rated securities.
See "Risk Factors."
 
The Fund may invest any remaining assets in common stocks; securities which have
not been registered under the Securities Act of 1933 (Rule 144A Securities);
securities issued or guaranteed by the U.S. government or its agencies or
instrumentalities; corporate bonds rated Baa or better by Moody's or BBB or
better by S&P (investment grade bonds); shares of other investment companies
with similar investment objectives; high grade commercial paper;
<PAGE>   156

certificates of deposit, time deposits and bankers' acceptances issued by banks
having net assets of at least $1 billion as of the end of their most recent
fiscal year, and other money market instruments; floating and variable rate
notes; repurchase agreements; money market funds; receipts (including TR's,
TIGR's and CATS), dollar-denominated securities of foreign issuers; Standard and
Poor's Depository Receipts ("SPDRs"); and cash. The Fund may purchase securities
on a forward commitment or when-issued basis, where such purchases are for
investment and not for leveraging purposes; however, the Fund may sell these
securities before the settlement date if it is deemed advisable. No additional
forward commitments will be made if more than 20% of the Fund's net assets would
be so committed. The Fund is permitted to lend securities in which it invests.
The Fund will limit its securities lending practice to 33 1/3% of its total
assets. The Fund will restrict its investments in illiquid securities to 15% of
its net assets.
 
For temporary defensive purposes during periods when the Advisor determines that
market conditions warrant, the Fund may invest up to 100% of its assets in money
market instruments described above and it also may hold a portion of its assets
in cash. The Fund will not be pursuing its investment objective to the extent
that a substantial portion of its assets are invested in money market
securities.
 
In the event that a security owned by the Fund is downgraded below the stated
ratings categories, the Advisor or SubAdvisor will take appropriate action with
regard to the security.
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
The Fund's shares will fluctuate in value with the value of the underlying
securities in its portfolio. Because of their fixed income features, however,
convertible securities are expected to fluctuate in value to a lesser degree
than the common stock into which they are convertible. Changes in the value of
the Fund's portfolio securities will not affect cash income received from
ownership of such securities, but will affect the Fund's net asset value.
 
Securities rated BBB by S&P or Baa by Moody's are deemed by these rating
services to have some speculative characteristics and adverse economic
conditions or other circumstances which are more likely to lead to a weakened
capacity to make principal and interest payments than is the case with higher
grade bonds.
 
Up to 15% of the Fund's portfolio may consist of dollar-denominated securities
of foreign issuers, which may bear greater investment risks than those of U.S.
domestic issuers, including political and economic instability, expropriation of
foreign deposits and other restrictions which may adversely affect the payment
of principal and interest on such securities. See "Description of Permitted
Investments."
 
RISKS ASSOCIATED WITH CONVERTIBLE SECURITIES
 
Investments in lower-rated debt securities (i.e. securities rated below BBB by
S&P or Baa by Moody's) bear certain risks, including the risk that such
securities may be thinly traded, which can adversely affect the price at which
these securities can be sold and can result in high transaction costs. Market
quotations may not be available, and therefore, judgment plays a greater role in
valuing lower-rated debt securities than securities for which more extensive
quotations and last sale information are available. Adverse publicity and
changing investor perceptions may affect the ability of outside pricing services
to value lower-rated debt securities, and the Fund's ability to dispose of these
securities.
 
The market price of lower-rated debt securities may decline significantly in
periods of general economic difficulty which may follow periods of rising
interest rates. During an economic downturn or a prolonged period of rising
interest rates, the ability of issuers of lower-rated debt to meet their payment
obligations on these securities may be impaired.
<PAGE>   157
 
 6
 
The Fund may invest in securities which are rated as low as 'Caa' by Moody's or
'CCC' by S&P. Securities rated 'Caa' by Moody's are of poor standing and may be
in default or may present elements of danger with respect to principal or
interest. Debt rated 'CCC' by S&P is regarded as having speculative
characteristics with respect to capacity to pay interest and repay principal. In
the event of adverse business, financial, and economic conditions, debt rated
'CCC' is not likely to have the capacity to repay principal.
 
INVESTMENT LIMITATIONS
 
The Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the U.S. government or its agencies or instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of the Fund would be invested in the securities of such issuer. This
restriction applies to 75% of the Fund's assets.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies or instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objective and policies; (b) enter into repurchase
agreements; and (c) engage in securities lending as described in this Prospectus
and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Fund. Fundamental policies cannot be changed with
respect to the Fund without the consent of a majority of the Fund's outstanding
shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor continuously
reviews, supervises and administers the Fund's investment program. The Advisor
discharges its responsibilities subject to the supervision of, and policies
established by, the Trustees of the Trust. The Trust's shares are not sponsored,
endorsed or guaranteed by, and do not constitute obligations or deposits of, the
Advisor and are not guaranteed by the FDIC or any other governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .60% of the average daily net assets of the Fund. The Advisor
may from time to time waive all or a portion of its fee in order to limit the
operating expenses of the Fund. Any such waiver is voluntary and may be
terminated at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, predecessor of the
Advisor, received .60% of the average daily net assets of the Fund.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of the Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California,
<PAGE>   158
 
 7
 
N.A., and the resulting bank changed its name to Union Bank of California, N.A.
At the same time, the banks' investment management divisions combined. Each of
Union Bank and The Bank of California, N.A. (or its predecessor bank) has been
in banking since the early 1900's, and historically, each has had significant
investment functions within its trust and investment division. Union Bank of
California, N.A., is a subsidiary of The Bank of Tokyo-Mitsubishi, Ltd.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE SUBADVISOR
 
The Advisor and Bank of Tokyo-Mitsubishi Trust Company (the "SubAdvisor") have
entered into an investment subadvisory agreement (the "Investment SubAdvisory
Agreement"). Under the Investment SubAdvisory Agreement, the SubAdvisor makes
the investment decisions for the assets of the Fund, subject to the supervision
of, and policies established by, the Advisor and the Trustees of the Trust.
 
Bank of Tokyo-Mitsubishi Trust Company, headquartered at 1251 Avenue of the
Americas, New York, New York 10116, and with offices at 100 Broadway, New York,
New York 10005, operates as a wholly-owned subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd. The SubAdvisor was formed by the combination on April 1,
1996, of Bank of Tokyo Trust Company, a wholly-owned subsidiary of The Bank of
Tokyo, Ltd., and Mitsubishi Bank Trust Company of New York, a wholly-owned
subsidiary of The Mitsubishi Bank, Ltd. Bank of Tokyo Trust Company was the
surviving entity, and changed its name to Bank of Tokyo-Mitsubishi Trust
Company. Prior to the combination, subadvisory services were provided by Bank of
Tokyo Trust Company. Bank of Tokyo Trust Company was established in 1955, and
has provided trust services since that time and management services since 1965.
 
The SubAdvisor serves as portfolio manager to bank common funds, employee
benefit funds and personal trust accounts, managing assets in money market,
equity and fixed income portfolios. As of April 1, 1996 Bank of Tokyo-Mitsubishi
Trust Company managed assets of $750 million in individual portfolios and
collective funds. In addition, the SubAdvisor also serves as SubAdvisor to the
Trust's Government Securities, Emerging Growth and Blue Chip Growth Funds.
 
The SubAdvisor is entitled to a fee, which is calculated daily and paid monthly
out of the Advisor's fee, at an annual rate of .30% of the average daily net
assets of the Fund. For the fiscal year ended January 31, 1996, Bank of Tokyo
Trust Company, predecessor of the SubAdvisor, received .30% of the average net
assets of the Fund.
 
The day-to-day management of the Convertible Security Fund's investments is the
responsibility of a team of investment professionals.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of the Fund's Investment Class
shares. Any such waiver is voluntary and may be terminated at any time in the
Administrator's sole discretion.
<PAGE>   159

THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional Class
and Cash Sweep Class shares of the Trust and the Investment Class shares of the
Convertible Securities, Government Securities, Emerging Growth, Blue Chip Growth
and International Equity Funds. Compensation for these services is paid under
the Administration Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days written notice by either party, or upon assignment by the
Distributor.
 
The Investment Class shares have a distribution plan ("Investment Class Plan").
The Distribution Agreement and the Investment Class Plan provide that the
Investment Class shares of the Fund may bear the following distribution
expenses: (1) the cost of prospectuses, reports to Shareholders, sales
literature and other materials for potential investors; (2) advertising; and (3)
expenses incurred in connection with the promotion and sale of the Trust's
shares including the Distributor's expenses for travel, communication, and
compensation and benefits for sales personnel. In addition, the Trust pays the
Distributor a fee of up to .40% of the Fund's Investment Class shares average
daily net assets, of which a maximum of .25% may be used to compensate
broker/dealers and service providers which provide administrative and/or
distribution services to Investment Class Shareholders or to their other
customers who beneficially own Investment Class shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Fund may be made on days on which
both the New York Stock Exchange and the Federal Reserve wire system are open
for business ("Business Days"). The minimum initial investment is $2,000 ($1,000
for IRAs); however, the minimum investment may be waived in the Distributors'
discretion. All subsequent purchases must be in amounts of at least $1,000 ($500
for IRAs).
 
Purchase orders for shares will be executed at a per share price equal to the
net asset value next determined after the receipt of the purchase order by the
Distributor (plus any applicable sales charge). The purchase price of shares of
the Fund is the net asset value next determined after a purchase order is
received and accepted by the Trust (plus a sales charge). The net asset value
per share of the Fund is determined by dividing the total market value of the
Fund's investments and other assets, less any liabilities, by the total number
of outstanding shares of the Fund. Net asset value per share is determined daily
as of 4:00 p.m., Eastern time, on any Business Day. Purchases will be made in
full and fractional shares of the Trust calculated to three decimal places. The
Trust reserves the right to reject a purchase order when the Distributor
determines that is not in the best interest of the Trust and/or its Shareholders
to accept such order.
 
Shares of the Fund are offered only to residents of states in which the shares
are eligible for purchase.
 
HOW TO PURCHASE THROUGH FINANCIAL INSTITUTIONS
 
Shares may be purchased through financial institutions, including the Adviser,
that provide distribution assistance or shareholder services. Shares purchased
by persons ("Customers") through financial institutions may be held of record by
the financial institution. Financial institutions may impose an earlier cut-off
time for receipt of purchase orders directed through them to allow for
processing and transmittal of these orders to the Transfer Agent for
effectiveness the same day.
<PAGE>   160
 
 9
 
Customers should contact their financial institution for information as to that
institution's procedures for transmitting purchase, exchange or redemption
orders to the Trust.
 
Customers who desire to transfer the registration of shares beneficially owned
by them but held of record by a financial institution should contact the
institution to accomplish such change.
 
Depending upon the terms of a particular Customer account, a financial
institution may charge a Customer account fees. Information concerning these
services and any charges will be provided to the Customer by the financial
institution.
 
SALES CHARGES
 
The following table shows the regular sales charge on Investment Class shares to
a "single purchaser" (defined below) together with the dealer discount paid to
dealers and the agency commission paid to brokers (collectively the
"commission"):

</TABLE>
 
- ---------------
* A contingent deferred sales charge of 1.00% will be assessed against any
  proceeds of any redemption of such Investment Class shares prior to one year
  from date of purchase.
 
The commissions shown in the table apply to sales through authorized dealers and
brokers. Under certain circumstances, the Distributor may use its own funds to
compensate financial institutions and intermediaries in amounts that are
additional to the commissions shown above. In addition, the Distributor may,
from time to time and at its own expense, provide promotional incentives in the
form of cash or other compensation to certain financial institutions and
intermediaries whose registered representatives have sold or are expected to
sell significant amounts of the Investment Class shares of the Fund. Such other
compensation may take the form of payments for travel expenses, including
lodging, incurred in connection with trips taken by qualifying registered
representatives to places within or without the United States. Under certain
circumstances, commissions up to the amount of the entire sales charge may be
reallowed to dealers or brokers, who might then be deemed to be "underwriters"
under the Securities Act of 1933. Commission rates may vary among the Funds.
 
In calculating the sales charge rates applicable to current purchases of a
Fund's shares, a "single purchaser" is entitled to cumulate current purchases
with the net purchases of previously purchased shares of the Fund and other of
the Trust's funds (the "Eligible Funds") which are sold subject to a comparable
sales charge.
 
The term "single purchaser" refers to (i) an individual, (ii) an individual and
spouse purchasing shares of the Fund for their own account or for trust or
custodial accounts for their minor children, or (iii) a fiduciary purchasing for
any one trust, estate or fiduciary account, including employee benefit plans
created under Sections 401, 403(b) or 457 of the Internal Revenue Code of 1986,
as amended (the "Code"), including related plans of the same employer. To be
entitled to a reduced sales charge based upon shares already owned, the investor
must ask the Distributor for such entitlement at the time of purchase and
provide the account number(s) of the investor, the investor and spouse, and
their minor children, and give the age of such children. The Fund may amend or
terminate this right of accumulation at any time as to subsequent purchases.
 
LETTER OF INTENT.  By initially investing at least $2,000 and submitting a
Letter of Intent to the Distributor, a "single purchaser" may purchase shares of
the Fund and the other Eligible Funds
<PAGE>   161
 
 10
 
during a 13-month period at the reduced sales charge rates applying to the
aggregate amount of the intended purchases stated in the Letter. The Letter may
apply to purchases made up to 90 days before the date of the Letter. To receive
credit for such prior purchases and later purchases benefitting from the Letter,
the Shareholder must notify the Transfer Agent at the time the Letter is
submitted that there are prior purchases that may apply, and, at the time of
later purchases, notify the Transfer Agent that such purchases are applicable
under the Letter.
 
OTHER CIRCUMSTANCES.  No sales charge is imposed on Investment Class shares of
the Fund: (i) issued in plans of reorganization, such as mergers, asset
acquisitions and exchange offers, to which the Trust is a party; (ii) sold to
dealers or brokers that have a sales agreement with the Distributor, for their
own account or for retirement plans for their employees or sold to employees
(and their spouses) of dealers or brokers that certify to the Distributor at the
time of purchase that such purchase is for their own account (or for the benefit
of such employees' minor children); (iii) in aggregate purchases of $1 million
or more by tax-exempt organizations enumerated in Section 501(c) of the Code, or
employee benefit plans created under Sections 401, 403(b) or 457 of the Code;
(iv) sold to employees and families of the Advisor and its affiliates; (v) sold
to fiduciary accounts of the Advisor and its affiliates; or (vi) purchased with
proceeds from the recent redemption of shares of a mutual fund with similar
investment objectives and policies for which a sales charge was paid.
 
The waiver of the sales charge under clause (vi) applies only if the following
conditions are met: the purchase must be made within 60 days of the redemption;
the Distributor must be notified in writing by the investor, or his or her
agent, at the time a purchase is made; and a copy of the investor's account
statement showing such redemption must accompany such notice. The waiver policy
with respect to the purchase of shares through the use of proceeds from a recent
redemption above will not continue indefinitely and may be discontinued at any
time without notice. Investors should contact the Distributor to confirm
continued availability prior to initiating the procedures described in clause
(vi).
 
Shareholders who desire to redeem shares of the Trust must place their
redemption orders prior to 4:00 p.m., Eastern time, on any Business Day for the
order to be accepted on that Business Day. The redemption price is the net asset
value of the Fund next determined after receipt by the Distributor of the
redemption order. Payment on redemption will be made as promptly as possible
and, in any event, within seven calendar days after the redemption order is
received.
 
Payment to shareholders for shares redeemed will be made within seven days after
the Transfer Agent receives the valid redemption request. At various times,
however, a Fund may be requested to redeem shares for which it has not yet
received good payment; collection of payment may take ten or more days. In such
circumstances, the redemption request will be rejected by the Fund. Once a Fund
has received good payment for the shares a shareholder may submit another
request for redemption.
 
Due to the relatively high costs of handling small investments, each Fund
reserves the right to redeem your shares at net asset value, if, your account in
any Fund has a value of less than the minimum initial purchase amount.
Accordingly, if you purchase shares of any Fund in only the minimum investment
amount, you may be subject to involuntary redemption if you redeem any shares.
Before any Fund exercises its right to redeem such shares you will be given
notice that the value of the shares in your account is less than the minimum
amount and will be allowed 60 days to make an additional investment in such Fund
in an amount which will increase the value of the account to at least the
minimum amount.
 
Neither the Transfer Agent nor the Trust will be responsible for any loss,
liability, cost or expense for acting upon wire or telephone instructions that
it reasonably believes to be genuine. The Trust and Transfer Agent will each
employ reasonable
<PAGE>   162
 
 11
 
procedures to confirm that instructions, communicated by telephone are genuine.
Such procedures may include taping of telephone conversations.
 
If market conditions are extraordinarily active or other extraordinary
circumstance exist, and you experience difficulties placing redemption orders by
telephone, you may consider placing your order by mail.
 
PURCHASES BY EXCHANGE
 
As permitted pursuant to any rule, regulation or order promulgated by the
Securities and Exchange Commission, shareholders of Investment Class Shares of
other funds of the Trust that have similar sales charges may tender their shares
of those Funds for exchange into the number of shares (including fractional
shares) which have a value equal to the total net asset value of shares tendered
divided by the net asset value of Investment Class shares of the Fund next
determined after such order is received. Shares issued pursuant to this offer
will not be subject to the sales charge described above or any other charge. The
Fund may modify or terminate this exchange offer at any time upon 60 days'
notice.
 
PERFORMANCE
 
From time to time, the Fund may advertise yield and total return. These figures
will be based on historical earnings and are not intended to indicate future
performance. The yield of the Fund refers to the annualized income generated by
an investment in the Fund over a specified 30-day period. The yield is
calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year
and is shown as a percentage of the investment.
 
The total return of the Fund refers to the average compounded rate of return to
a hypothetical investment for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gain
distributions. The total return of the Fund may also be quoted as a dollar
amount or on an aggregate basis, an actual basis, without inclusion of any sales
charge, or with a reduced sales charge in advertisements distributed to
investors entitled to a reduced sales charge.
 
The Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long-term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.

TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local income tax treatment of the Fund or
its Shareholders. In addition, state and local income tax consequences of an
investment in the Fund may differ from the federal income tax consequences
discussed below. Accordingly, Shareholders are urged to consult their tax
advisors regarding specific questions as to federal, state and local income
taxes. Additional information concerning taxes is set forth in the Statement of
Additional Information.
 
TAX STATUS OF THE FUND:
 
The Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. The Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on that part of its net investment company taxable income and
net capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
The Fund will distribute substantially all of its net investment income
(including net short-term capital gain) and net capital gain to Shareholders.
Dividends from the Fund's net investment company taxable income are taxable to
Shareholders as ordinary income (whether received in cash or in additional
shares) to the extent of the Fund's earnings and profits. Any net capital gains
will be distributed at least annually and will be taxed to Shareholders as
long-term capital gains. Dividends paid by the Fund to corporate Shareholders
will qualify for the dividends received deduction to the extent derived from
dividends received by the Fund from domestic corporations. A portion of such
dividends may be subject to the alternative minimum tax. Distributions of net
capital gain do not qualify for the dividends-received deduction and are taxable
to Shareholders as long-term capital gain, regardless of how long Shareholders
have held shares and regardless of whether the distributions are received in
cash or in additional shares. The Fund will provide annual reports to
Shareholders of the federal income tax status of all distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments,
the Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because the Fund distributes
all of its net investment income to its shareholders, the Fund may have to sell
portfolio securities to distribute such imputed income, which may occur at a
time when the Advisor or SubAdvisor would not have chosen to sell such
securities and which may result in a taxable gain or loss.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level, and may be exempt, depending on the state,
when received by a Shareholder as income dividends from the Fund provided
certain state-specific conditions are satisfied. Interest realized on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. The Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from the Fund is considered tax exempt in their
particular state.
 
Income derived by the Fund from obligations of foreign issuers may be subject to
foreign withholding taxes. The Fund will not be able to elect to treat
Shareholders as having paid their proportionate share of such taxes.

Dividends declared by the Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared if paid by the Fund any time during the following January.
 
The Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Each sale, exchange, or redemption of Fund Shares is a taxable transaction to
the Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate series of shares and different classes of each fund. In addition
to the Fund, the Trust consists of the following funds: Treasury Money Market
Fund, Money Market Fund, California Tax-Free Money Market Fund, Value Momentum
Fund, Intermediate-Term Bond Fund, Limited Maturity Government Fund, California
Intermediate Tax-Free Bond Fund, Balanced Fund, Growth Equity Fund, Blue Chip
Growth Fund, Government Securities Fund, Emerging Growth Fund and International
Equity Fund. All consideration received by the Trust for shares of any fund and
all assets of such fund belong to that fund and would be subject to liabilities
related thereto. The Trust reserves the right to create and issue shares of
additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings of Shareholders, but approval will be sought for certain changes
in the operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon the written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate
assistance and information to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of
the Fund is distributed in the form of monthly dividends to Shareholders of
record. Currently, capital gains of
<PAGE>   165
 
 14
 
the Fund, if any, will be distributed at least annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares at the net asset value next determined
following the record date, unless the Shareholder has elected to take such
payment in cash. Shareholders may change their election by providing written
notice to the Administrator at least 15 days prior to the change.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on the Investment Class shares will typically be lower
than the dividends payable on the Institutional Class shares because of the
distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank, N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of permitted investments for the Fund:
 
CONVERTIBLE BONDS AND CONVERTIBLE PREFERRED STOCK--Convertible bonds are bonds
convertible into a set number of shares of another form of security (usually
common stock) at a prestated price. Convertible bonds have characteristics
similar to both fixed income and equity securities. Convertible preferred stock
is a class of capital stock that pays dividends at a specified rate and that has
preference over common stock in the payment of dividends and the liquidation of
assets. Convertible preferred stock is preferred stock exchangeable for a given
number of common stock shares, and has characteristics similar to both
fixed-income and equity securities. Because of the conversion feature, the
market value of convertible bonds and convertible preferred stock tend to move
together with the market value of the underlying stock. As a result, the Fund's
selection of convertible bonds and convertible preferred stock is based, to a
great extent, on the potential for capital appreciation that may exist in the
underlying stock. The value of convertible bonds and convertible preferred stock
is also affected by prevailing interest rates, the credit quality of the issuer
and any call provisions.
 
CORPORATE BONDS--Interest-bearing or discounted corporate securities that
obligates the issuer to pay the bondholder a specified sum of money, usually at
specific intervals, and to repay the principal amount of the loan at maturity.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including: futures, options
(e.g., puts and calls), options on futures, swap agreements, and some mortgage-
backed securities (CMOs, REMICs, IOs and POs). See elsewhere in this
"Description of Permitted Investments" for discussions of these various
instruments, and see "Investment Objectives and Policies" for more information
about any policies and limitations applicable to their use.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date, and no interest
accrues to the Fund before settlement. These securities are subject to market
fluctuation
<PAGE>   166
 
 15
 
due to changes, real or anticipated, in market interest rates and the public's
perception of the creditworthiness of the issuer and will have the effect of
leveraging the Fund's assets. The Fund will establish one or more segregated
accounts with the Custodian, and the Fund will maintain liquid, high-grade
assets in an amount at least equal in value to the Fund's commitments to
purchase when-issued securities.
 
LOWER-RATED, HIGHER-YIELDING, HIGH-RISK DEBT SECURITIES--High-yield, high-risk
securities consist of securities rated Ba or lower by Moody's or BB or lower by
S&P. Lower-rated debt securities are considered speculative and involve greater
risk of loss than investment grade debt securities, and are more sensitive to
changes in the issuer's capacity to pay. For a description of the debt
securities ratings, see the "Appendix".
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial paper; and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and
broker-dealers.
 
REPURCHASE AGREEMENTS--Agreements by which the Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement.
The Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if the Fund realizes a loss in the sale
of the collateral. The Fund will enter into repurchase agreements only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based on established guidelines. Repurchase agreements are
considered loans under the 1940 Act.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
SECURITIES LENDING--In order to generate additional income, the Fund may lend
the securities in which it is invested pursuant to agreements requiring that the
loan be continuously secured by cash, securities of the U.S. Government or its
agencies or instrumentalities or any combination of cash and such securities as
collateral equal to 100% of the market value at all times of the loaned
securities. The lending Fund will continue to receive interest on the loaned
securities while simultaneously earning interest on the investment of cash
collateral. Collateral is marked to market daily to provide a level of at least
equal to the market value of the loaned securities. There may be risks of delay
in receiving additional collateral or risks of delay in recovery of the
securities or even loss of rights in the collateral should the borrower of the
securities fail financially.
 
SECURITIES OF FOREIGN ISSUERS--Securities issued by non-U.S. issuers. There may
be certain risks connected with investing in foreign securities, including risks
of adverse political and economic developments (including possible governmental
seizure or nationalization of assets), the possible imposition of exchange
controls or other governmental restrictions, including less uniformity in
accounting and reporting requirements, the
<PAGE>   167
 
 16
 
possibility that there will be less information on such securities and their
issuers available to the public, the difficulty of obtaining or enforcing court
judgments abroad, restrictions on foreign investments in other jurisdictions,
difficulties in effecting repatriation of capital invested abroad, and
difficulties in transaction settlements and the effect of delay on shareholder
equity. Foreign securities may be subject to foreign taxes, which reduce yield,
and may be less marketable than comparable U.S. securities. The Fund may be
affected favorably or unfavorably by changes in the exchange rates or exchange
control regulations between foreign currencies and the U.S. dollar. Changes in
foreign currency exchange rates may also affect the value of dividends and
interest earned, gains and losses realized on the sale of securities and net
investment income and gains, if any, distributed to shareholders by the Fund.
See "Risk Factors."
 
STANDARD & POOR'S DEPOSITARY RECEIPTS ("SPDRs")--Interests in a unit investment
trust holding a portfolio of securities linked to the S&P 500 Index. SPDRs
closely track the underlying portfolio of securities, trade like a share of
common stock and pay periodic dividends proportionate to those paid by the
portfolio of stocks that constitutes the S&P 500 Index. For further information
regarding a Fund's Investment in SPDRs, see the Statement of Additional
Information.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of such
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's"), "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than
interest-paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed funds of
securities. The following provides basic information about the Investment Class
shares of the GROWTH EQUITY, VALUE MOMENTUM, BALANCED and EMERGING GROWTH FUNDS
(each a "Fund"). This summary is qualified in its entirety by reference to the
more detailed information provided elsewhere in the Prospectus and in the
Statement of Additional Information.
 
WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?  THE BALANCED FUND seeks to provide
both capital appreciation and income. THE VALUE MOMENTUM FUND seeks long-term
capital growth with a secondary objective of income. THE GROWTH EQUITY FUND
seeks long-term capital growth. THE EMERGING GROWTH FUND seeks long-term growth
of capital by investing in a diversified portfolio of equity securities of small
capitalization, emerging growth companies. See "Investment Objectives."
 
WHAT ARE THE FUNDS' PERMITTED INVESTMENTS?  Each of the Funds may invest,
consistent with its investment objectives, in equity securities including common
stocks and securities convertible into common stocks. Each Fund, except the
Emerging Growth Fund, may also invest, consistent with its investment objective
and investment policies in debt securities. See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUNDS?  The investment
policies of each Fund entail certain risks and considerations of which an
investor should be aware. Each of the Funds may purchase common stocks and other
equity securities that are volatile and which may fluctuate in value more than
other types of investments. Values of fixed income securities and,
correspondingly, share prices of Funds invested in such securities, tend to vary
inversely with interest rates, and may be affected by other market and economic
factors as well. In addition, the securities of the emerging growth companies in
which the Emerging Growth Fund may invest may be less liquid, and subject to
more abrupt or erratic market movements, than securities of larger, more
established growth companies. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE SUBADVISOR?  Bank of Tokyo-Mitsubishi Trust Company serves as the
SubAdvisor to the Emerging Growth Fund. See "The SubAdvisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  State Street Bank and Trust Company
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Investment Class shares of the Trust (except for the Convertible
Securities, Government Securities, Emerging Growth, Blue Chip Growth and
International Equity Funds). SEI Financial Management Corporation serves as
transfer agent, dividend disbursing agent, and shareholder servicing agent for
the Institutional and Cash Sweep Class shares of the Trust and for the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business. ("Business Days"). The
minimum initial investment is $2,000 ($1,000 for IRAs). A purchase order will be
effective if the Distributor receives an order prior to 4:00 p.m., Eastern time.
Purchase orders for shares will be executed at a per share price equal to the
asset value next determined after the purchase order is effective (plus any
applicable sales charge). Redemption orders must be placed prior to 4:00 p.m.,
Eastern time on any Business Day for the order to be effective that day. See
"Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of the Funds is distributed in the form of monthly
dividends to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF A FUND AND SHOULD NOT
BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES MAY
BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist the
investor in understanding the various costs and expenses that may be directly or
indirectly borne by investors in the Investment Class shares of the Funds. The
Trust also offers Institutional Class shares of the Funds, which are subject to
the same expenses except there are no sales charges or distribution costs.
Additional information may be found under "The Administrator," "The Advisor" and
"The SubAdvisor."
 
The rules of the Securities and Exchange Commission require that the maximum
sales charge be reflected in the above table. However, certain investors may
qualify for reduced sales charges. See "Purchase and Redemption of Shares."
 
Long-term investors may pay more than the equivalent of the maximum front-end
sales charges otherwise permitted by the Rules of the National Association of
Securities Dealers ("NASD").

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Investment Class shares of the Trust's Growth Equity, Value Momentum,
Balanced and Emerging Growth Funds (each a "Fund"). Information regarding the
Trust's other funds is contained in separate prospectuses that may be obtained
from the Trust's Distributor, SEI Financial Services Company, 680 East
Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVES
 
THE BALANCED FUND seeks to provide both capital appreciation and income.
 
THE VALUE MOMENTUM FUND seeks long-term capital growth with a secondary
objective of income.
 
THE GROWTH EQUITY FUND seeks long-term capital growth.
 
THE EMERGING GROWTH FUND seeks long-term growth of capital by investing in a
diversified portfolio of equity securities of small capitalization, emerging
growth companies.
 
There can be no assurance that a Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
BALANCED FUND
 
The Balanced Fund invests in a combination of equity, fixed-income, and money
market securities. Under normal market conditions, the Fund will invest between
50% and 70% of its total assets in equity securities, including common stocks,
warrants, and U.S. dollar denominated securities of foreign issuers and both
preferred stock and debt securities convertible into common stocks. The Fund may
invest in a broad spectrum of common stocks with varying characteristics. All of
the common stocks in which the Fund invests (including foreign securities in the
form of American Depositary Receipts ("ADRs")) are traded on registered
exchanges or the over-the-counter market. Under normal market conditions a
minimum of 25% of the Fund's total assets will be invested in senior fixed
income securities. Such securities consist of bonds, debentures, and similar
obligations or instruments which constitute a security and evidence
indebtedness. Corporate bonds and debentures will be rated AAA, AA, A, or BBB by
Standard & Poor's Corporation ("S&P") or Aaa, Aa, A, or Baa by Moody's Investors
Service ("Moody's") or determined by the Advisor to be of comparable quality at
the time of purchase. The Fund may also invest in mortgage-backed securities
that are rated in one of the top two rating categories by Moody's or S&P, and
may invest in other asset-backed securities backed by company receivables, truck
and auto loans, leases, and credit card receivables.
 
The Fund may also buy and sell options, futures contracts and options on
futures. The Fund may enter into futures contracts and options on futures only
to the extent that obligations under such contracts or transactions, together
with options on securities represent not more than 25% of the Fund's assets. The
aggregate value of options on securities (long puts and calls) will not exceed
10% of the Fund's net assets at the time such options are purchased by the Fund.
 
The Fund may invest in securities issued or guaranteed by foreign governments,
their political subdivisions, agencies or instrumentalities and obligations of
supranational entities such as the World Bank and the Asian Development Bank.
<PAGE>   174
 
 6
 
Money market instruments the Fund may invest in consist of: (i) commercial paper
rated at least A-1 by S&P or P-1 by Moody's at the time of investment, or, if
not rated, determined by the Advisor to be of comparable quality; (ii)
obligations (certificates of deposit, time deposits, bank master notes, and
bankers' acceptances) of thrift institutions, savings and loans, U.S. commercial
banks (including foreign branches of such banks), and U.S. and foreign branches
of foreign banks, provided that such institutions (or, in the case of a branch,
the parent institution) have total assets of $1 billion or more as shown on
their last published financial statements at the time of investment; (iii)
short-term corporate obligations rated at least A by S&P or A by Moody's at the
time of investment, or, if not rated, determined by the Advisor to be of
comparable quality; (iv) general obligations issued by the U.S. Government and
backed by its full faith and credit, and obligations issued or guaranteed as to
principal and interest by agencies or instrumentalities of the U.S. Government
(e.g., obligations issued by Farmers Home Administration, Government National
Mortgage Association, Federal Farm Credit Bank and Federal Housing
Administration); (v) receipts, including TR's, TIGR's and CATS; (vi) repurchase
agreements involving such obligations; (vii) loan participations; (viii) money
market funds and (ix) foreign commercial paper. The Fund may only purchase
interests in loan participations issued by a bank in the United States with
assets exceeding $1 billion and for which the underlying loan is issued by
borrowers in whose obligations the Fund may invest.
 
Certain of the obligations in which the Fund may invest may be variable or
floating rate instruments, may involve conditional or unconditional demand
features and may include variable amount master demand notes.
 
The Fund may enter into forward commitments, or purchase securities on a
when-issued basis. The Fund is permitted to invest in when-issued securities
where such purchases are for investment and not for leveraging purposes;
however, the Fund may sell these securities before the settlement date if it is
deemed advisable. No additional forward commitments will be made if more than
20% of the Fund's net assets would be so committed.
 
VALUE MOMENTUM FUND
 
Under normal market conditions, at least 65% of the Value Momentum Fund's assets
will be invested in equity securities, including common stocks, warrants to
purchase common stock, debt securities and preferred stocks convertible into
common stocks, and ADRs.
 
The Fund will be invested primarily in securities which the Advisor believes to
be undervalued relative to the market and to the security's historic valuation.
Stocks are then screened for positive price or earnings momentum. Securities
purchased will generally have a medium to high market capitalization. A majority
of the securities in which the Fund invests will be dividend paying. All of the
common stocks in which the fund invests are traded on registered exchanges or
the over-the-counter market.
 
The remainder of the Fund's assets may be invested in covered call options on
equity securities, money market instruments consisting of securities issued or
guaranteed by the U.S. government or its agencies or instrumentalities,
receipts, including TR's, TIGR's and CATS, money market funds, repurchase
agreements, certificates of deposit, time deposits, bank master notes and
bankers' acceptances issued by banks having net assets of at least $1 billion as
of the end of their most recent fiscal year, commercial paper rated at least A-1
by S&P or P-1 by Moody's and in cash.
 
GROWTH EQUITY FUND
 
Under normal market conditions, at least 65% of the Growth Equity Fund's assets
will be invested in equity securities consisting of common stocks, warrants to
purchase common stocks, U.S. dollar denominated equity securities of foreign
issuers, and debt securities and preferred stock convertible into common stocks.
<PAGE>   175

The Fund may also invest in covered call options on equity securities and money
market instruments consisting of securities issued or guaranteed by the U.S.
government or its agencies or instrumentalities, receipts, including TR's,
TIGR's and CATS, money market funds, repurchase agreements, certificates of
deposit, time deposits, bank master notes and bankers' acceptances issued by
banks having net assets of at least $1 billion as of the end of their most
recent fiscal year, commercial paper rated at least A-1 by S&P or P-1 by Moody's
and in cash. All of the common stocks in which the Fund invests (including
foreign securities in the form of ADRs ) are traded on registered exchanges or
in the over the counter market.
 
EMERGING GROWTH FUND
 
Under normal market conditions, the Emerging Growth Fund will invest at least
65% of its assets in equity securities (i.e., common stocks and convertible
preferred stocks) of small capitalization (i.e., companies with capitalization
between $50 million and $1 billion) with the potential for growth or which, in
the Advisor's opinion, have potential for above-average long-term capital
appreciation. An emerging growth company is one which, in the Advisor's
judgment, is in the developing stages of its life cycle and has demonstrated or
is expected to achieve rapid growth in earnings and/or revenues. Emerging growth
companies are characterized by opportunities for rapid growth rates and/or
dynamic business changes. Emerging growth companies, regardless of size, tend to
offer the potential for accelerated earnings or revenue growth because of new
products or technologies, new channels of distribution, revitalized management
or industry conditions, or similar opportunities. A company may or may not yet
be profitable at the time the Fund invests in its securities. Current income
will not be a criterion of investment selection, and any such income should be
considered incidental. Many of the securities in which the Fund invests will not
pay dividends.
 
The Fund may also invest in equity securities of companies in "special equity
situations," meaning companies experiencing unusual and possibly non-repetitive
developments, such as mergers; acquisitions; spin-offs; liquidations;
reorganizations; and new products, technology or management. Since a special
equity situation may involve a significant change from a company's past
experiences, the uncertainties in the appraisal of the future value of the
company's equity securities and the risk of a possible decline in the value of
the Fund's investments are significant.
 
The Fund may invest in U.S. dollar denominated equity securities of foreign
issuers traded as ADRs. All of the common stocks in which the Fund invests (with
the exception of Rule 144A Securities) are traded on registered exchanges or in
the over the counter market.
 
The balance of the Fund's assets may be invested in money market instruments,
options, futures and options on futures, shares of other investment companies
with similar investment objectives, Standard & Poor's Depositary Receipts
("SPDRs") and convertible bonds. The Fund may enter into futures contracts and
options on futures to the extent that obligations under such contracts or
transactions, together with options on securities, represent not more than 25%
of the Fund's assets. The aggregate value options on securities (long puts and
calls) will not exceed 10% of the Fund's net asset at the time such options are
purchased by the Fund.
 
The portfolio turnover rate for the Emerging Growth Fund for the fiscal year
ended January 31, 1996 was 131%. This rate of portfolio turnover may result in
higher brokerage execution costs and higher levels of capital gains.
 
GENERAL INVESTMENT POLICIES
 
For temporary defensive purposes during periods when the Advisor determines that
market conditions warrant, each Fund may invest up to 100% of its assets in
money market instruments consisting of securities issued or guaranteed by the
U.S. government or its agencies or
<PAGE>   176
 
 8
 
instrumentalities, receipts, including TR's, TIGR's and CATS, money market
funds, repurchase agreements, certificates of deposit, time deposits, bank
master notes and bankers' acceptances issued by banks having net assets of at
least $1 billion as of the end of their most recent fiscal year, commercial
paper rated at least A-1 by S&P or P-1 by Moody's, and in cash. A Fund will not
be pursuing its investment objective to the extent that a substantial portion of
its assets are invested in money market securities.
 
Each Fund will restrict its investments in illiquid securities to 15% of its net
assets.
 
Each of the Funds may engage in securities lending and will limit such practice
to 33 1/3% of its assets.
 
Each Fund may purchase securities which have not been registered under the
Securities Act of 1933 (Rule 144A Securities).
 
Each Fund may purchase options on stock indices to invest cash on an interim
basis. The aggregate premium paid on all options on stock indices cannot exceed
20% of the Fund's total assets.
 
In the event that a security owned by a Fund is downgraded below the stated
rating categories, the Advisor or SubAdvisor will take appropriate action with
regard to the security.
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
Since the Funds invest in equity securities, each Fund's shares will fluctuate
in value, and thus may be more suitable for long-term investors who can bear the
risk of short-term fluctuations. In addition, the market value of fixed income
securities bears an inverse relationship to changes in market interest rates,
which may affect the net asset value of shares. The longer the remaining
maturity of security, the greater is the effect of interest rate changes on its
market value. Generally, because of their fixed income features, convertible
securities will fluctuate in value to a lesser degree than the common stocks
into which they are convertible. Changes in the value of a Fund's fixed income
securities will not affect cash income received from ownership of such
securities, but will affect a Fund's net asset value.
 
Securities rated BBB by S&P or Baa by Moody's are deemed by these rating
services to have some speculative characteristics, and adverse economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than is the case with higher grade
bonds.
 
Investments in securities of foreign issuers may subject the Fund to different
risks than those attendant to investments in securities of U.S. issuers,
including differences in accounting, auditing and financial reporting standards,
the possibility of expropriation or confiscatory taxation, and political
instability. See "Description of Permitted Investments."
 
Given the uncertainty of the future value of emerging growth companies and
companies in special equity situations, the risk of possible decline in the
value of the Emerging Growth Fund's net assets are significant. Companies in
which the Emerging Growth Fund invests may offer greater opportunities for
capital appreciation than larger, more established companies, but investment in
such companies may involve certain special risks. These risks may be due to the
greater business risks of small size, limited markets and financial resources,
narrow product lines and frequent lack of depth in management. The securities of
such companies are often traded in the over-the-counter market and may not be
traded in volumes typical on a national securities exchange. Thus, the
securities of emerging growth companies may be less liquid, and subject to more
abrupt or erratic market movements than securities of larger, more established
growth companies. Since a "special equity situation" may involve a significant
change from a company's past experiences, the uncertainties in the appraisal of
the future value of the company's equity securities and the risk of a
<PAGE>   177
 
 9
 
possible decline in the value of the Fund's investments are significant.
 
INVESTMENT LIMITATIONS
 
Each Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the U.S. government or its agencies or instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of the Fund would be invested in the securities of such issuer. This
restriction applies to 75% of the Fund's assets.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies or instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objective and policies; (b) enter into repurchase
agreements; and (c) engage in securities lending as described in this prospectus
and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Funds. Fundamental policies cannot be changed with
respect to a Fund without the consent of a majority of the Fund's outstanding
shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of the Balanced, Value Momentum and Growth
Equity Funds and continuously reviews, supervises and administers each Fund's
investment program. The Advisor discharges its responsibilities subject to the
supervision of, and policies established by, the Trustees of the Trust. The
Trust's shares are not sponsored, endorsed or guaranteed by, and do not
constitute obligations or deposits of, the Advisor and are not guaranteed by the
FDIC or any other governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .60% of the average daily net assets of the Balanced, Growth
Equity and Value Momentum Funds and .80% of the average daily net assets of the
Emerging Growth Fund. Although the advisory fee for the Emerging Growth Fund is
higher than advisory fees paid by other mutual funds, the Trust believes that
the fee is comparable to the advisory fee paid by many other mutual funds with
similar investment objectives and policies. The Advisor may from time to time
waive all or a portion of its fee in order to limit the operating expenses of a
Fund. Any such waiver is voluntary and may be terminated at any time in the

investment functions within its trust and investment division. Union Bank of
California, N.A., is a subsidiary of The Bank of Tokyo-Mitsubishi, Ltd.

surviving entity, and changed its name to Bank of Tokyo-Mitsubishi Trust
Company. Prior to the combination, subadvisory services were provided by Bank of
Tokyo Trust Company. Bank of Tokyo Trust Company was established in 1955, and
has provided trust services since that time and management services since 1965.
 
The SubAdvisor serves as portfolio manager to bank common funds, employee
benefit funds and personal trust accounts, managing assets in money market,
equity and fixed income portfolios. As of April 1, 1996, the SubAdvisor managed
$750 million in individual portfolios and collective funds. In addition, the

assets of the Emerging Growth Fund. For the fiscal year ended January 31, 1996,
Bank of Tokyo Trust Company, predecessor of the SubAdvisor, received .50% of the
average daily net assets of the Emerging Growth Fund.

received and accepted by the Trust (plus a sales charge). The net asset value
<PAGE>   180
 
 12
 
per share of the Fund is determined by dividing the total market value of the
Fund's investments and other assets, less any liabilities, by the total number
of outstanding shares of the Fund. Net asset value per share is determined daily
as of 4:00 p.m., Eastern time, on any Business Day. Purchases will be made in

- ---------------
 
* A contingent deferred sales charge of 1.00% will be assessed against any
  proceeds of any redemption of such Investment Class shares prior to one year
  from date of purchase.
 
The commissions shown in the table apply to sales through authorized dealers and
brokers. Under certain circumstances, the Distributor may use its own funds to
compensate financial institutions and intermediaries in amounts that are
additional to the commissions shown above. In addition, the Distributor may,
from time to time and at its own expense, provide promotional incentives in the
form of cash or other compensation to certain financial institutions and
intermediaries whose registered representatives have sold or are expected to
sell significant amounts of the Investment Class shares of the Fund. Such other
compensation may take the form of payments for travel expenses, including
lodging, incurred in connection with trips taken by qualifying registered
representatives to places within or without the United States. Under certain
circumstances, commissions up to the amount of the entire sales charge may be
reallowed to dealers or brokers, who might then be deemed to be "underwriters"
under the Securities Act of 1933. Commission rates may vary among the Funds.
 
In calculating the sales charge rates applicable to current purchases of a
Fund's shares, a "single purchaser" is entitled to cumulate current purchases
with the net purchase of previously purchased shares of the Fund and other of
the Trust's funds (the "Eligible Funds") which are sold subject to a comparable
sales charge.
 
The term "single purchaser" refers to (i) an individual, (ii) an individual and
spouse purchasing shares of the Fund for their own account or for trust or
custodial accounts for their minor children, (iii) a fiduciary purchasing for
any one trust, estate or fiduciary account including employee benefit plans
created under Sections 401, 403(b) or 457 of the Internal Revenue Code of 1986,
as amended (the "Code"), including related plans of the same employer. To be
entitled to a reduced sales charge based upon shares already owned, the investor
must ask the Distributor for such entitlement at the time of purchase and
provide the account number(s) of the investor, the investor and spouse, and
their minor children, and give the age of such children. The Fund may amend or
terminate this right of accumulation at any time as to subsequent purchases.
 
LETTER OF INTENT.  By initially investing at least $2,000 and submitting a
Letter of Intent (the "Letter") to the Distributor, a "single purchaser" may
purchase shares of the Fund and the other Eligible Funds during a 13-month
period at the reduced sales charge rates applying to the aggregate amount of the
intended purchases stated in the Letter. The Letter may apply to purchases made
up to 90 days before the date of the Letter. To receive credit for such prior
purchases and later purchases benefitting from the Letter, the Shareholder must
notify the Transfer Agent at the time the Letter is submitted that there are
prior purchases that may apply, and, at the time of later purchases, notify the
Transfer Agent
<PAGE>   182
 
 14
 
that such purchases are applicable under the Letter.
 
RIGHTS OF ACCUMULATION.  In calculating the sales charge rates applicable to
current purchases of Investment Class shares, a "single purchaser" is entitled
to cumulate current purchases with the current market value of previously
purchased Investment Class shares of the Funds sold subject to a comparable
sales charge.
 
To exercise your right of accumulation based upon shares you already own, you
must ask the Distributor for this reduced sales charge at the time of your
additional purchase and provide the account number(s) of the investor, as
applicable, the investor and spouse, and their minor children. The Funds may
amend or terminate this right of accumulation at any time as to subsequent
purchases.
 
WAIVER OF SALES LOAD.  No sales charge is imposed on the Investment Class shares
of the Fund: (i) issued in plans of reorganization, such as mergers, asset
acquisitions and exchange offers, to which the Trust is a party; (ii) sold to
dealers or brokers that have a sales agreement with the Distributor, for their
own account or for retirement plans for their employees or sold to employees
(and their spouses) of dealers or brokers that certify to the Distributor at the
time of purchase that such purchase is for their own account (or for the benefit
of such employees' minor children); (iii) in aggregate purchases of $1 million
or more by tax-exempt organizations enumerated in Section 501(c) of the Code, or
employee benefit plans created under Sections 401, 403(b) or 457 of the Code;
(iv) sold to employees and families of the Advisor and its affiliates; (v) sold
to fiduciary accounts of the Advisor and its affiliates; (vi) purchased with
proceeds from the recent redemption of shares of a mutual fund with similar
investment objectives and policies for which a sales load was paid; or (vii)
sold to purchasers of Investment Class shares of the Growth Equity Fund that are
sponsors of other investment companies that are unit investment trusts for
deposit by such sponsors into such unit investment trusts, and to purchasers of
Investment Class shares of the Growth Equity Fund that are holders of such unit
investment trusts that invest distributions from such investment trusts in
Investment Class shares of the Growth Equity Fund.
 
The waiver of the sales charge under clause (vi) applies only if the following
conditions are met: the purchase must be made within 60 days of the redemption;
the Distributor must be notified in writing by the investor, or his or her
agent, at the time a purchase is made; and a copy of the investor's account
statement showing such redemption must accompany such notice. The waiver policy
with respect to the purchase of shares through the use of proceeds from a recent
redemption above will not continue indefinitely, and may be discontinued at any
time without notice. Investors should contact the Distributor to confirm
continued availability prior to initiating the procedures described in clause
(vi).
 
REDEMPTION OF SHARES
 
You may redeem your shares of the Balanced, Value Momentum and Growth Equity
Funds without charge on any Business Day. There is, however, a $15 charge for
wiring redemption proceeds to a shareholder's designated account. Shares may be
redeemed by mail, by telephone or through a pre-arranged systematic withdrawal
plan. Investors who own shares held by a financial institution should contact
that institution for information on how to redeem shares.
 
BY MAIL
 
A written request for redemption of shares of the Balanced, Value Momentum and
Growth Equity Funds must be received by the Transfer Agent, P.O. Box 8416,
Boston, Massachusetts 02266-8416 in order to constitute a valid redemption
request.
 
If the redemption request exceeds $5,000, or if the request directs the proceeds
to be sent or wired to an address different from that of record, the
<PAGE>   183
 
 15
 
Transfer Agent may require that the signature on the written redemption request
be guaranteed. You should be able to obtain a signature guarantee from a bank,
broker, dealer, credit union, securities exchange or association, clearing
agency or savings association. Notaries public cannot guarantee signatures. The
signature guarantee requirement will be waived if all of the following
conditions apply: (1) the redemption is for not more than $5,000 worth of
shares, (2) the redemption check is payable to the shareholder(s) of record, and
(3) the redemption check is mailed to the shareholder(s) at his or her address
of record.
 
BY TELEPHONE
 
You may redeem your shares of the Balanced, Value Momentum and Growth Equity
Funds by calling the Transfer Agent at 1-800-734-2922. Under most circumstances,
payments will be transmitted on the next Business Day following receipt of a
valid request or redemption. You may have the proceeds mailed to your address or
wired to a commercial bank account previously designated on your Account
Application. There is no charge for having redemption proceeds mailed to you,
but there is a $15 charge for wiring redemption proceeds.
 
You may request a wire redemption for redemptions of shares of the Balanced,
Value Momentum and Growth Equity Funds in excess of $500 by calling the Transfer
Agent at 1-800-734-2922 who will deduct a wire charge of $15 from the amount of
the wire redemption. Shares cannot be redeemed by Federal Reserve wire on
Federal holidays restricting wire transfers.
 
Neither the Transfer Agent nor the Trust will be responsible for any loss,
liability, cost or expense for acting upon wire or telephone instructions that
it reasonably believes to be genuine. The Trust and Transfer Agent will each
employ reasonable procedures to confirm that instructions, communicated by
telephone are genuine. Such procedures may include taping of telephone
conversations.
 
If market conditions are extraordinarily active or other extraordinary
circumstance exist, and you experience difficulties placing redemption orders by
telephone, you may consider placing your order by mail.
 
SYSTEMATIC WITHDRAWAL PLAN ("SWP")
 
The Balanced, Value Momentum and Growth Equity Funds offer a Systematic
Withdrawal Plan ("SWP"), which you may use to receive regular distributions from
your account. Upon commencement of the SWP, your account must have a current net
asset value of $5,000 or more. You may elect to receive automatic payments via
check or ACH of $100 or more on a monthly, quarterly, semi-annual or annual
basis. You may arrange to receive regular distributions from your account via
check or ACH by completing this section in the Account Application form.
 
To participate in the SWP, you must have your dividends automatically
reinvested. You should realize that if your automatic withdrawals exceed income
dividends, your invested principal in the account will be depleted. Thus,
depending on the frequency and amounts of the withdrawal payments and/or any
fluctuations in the net asset value per share, your original investment could be
exhausted entirely. You may change or cancel the SWP at any time on written
notice to the Transfer Agent. The Transfer Agent may require that the signature
on the written notice be guaranteed.
 
It is generally not in your best interest to be participating in the SWP at the
same time that you are purchasing additional shares if you have to pay a sales
load in connection with such purchases.
 
OTHER INFORMATION REGARDING REDEMPTIONS.
 
Shareholders who desire to redeem shares of the Trust must place their
redemption orders prior to 4:00 p.m., Eastern time, on any Business Day for the
order to be accepted on that Business Day. The redemption price is the net asset
value of the Fund next determined after receipt by the Distributor of the
redemption order. Payment on redemption will be made as promptly as possible
<PAGE>   184
 
 16
 
and, in any event, within seven calendar days after the redemption order is
received.
 
Payment to shareholders for shares redeemed will be made within seven days after
the Transfer Agent receives the valid redemption request. At various times,
however, a Fund may be requested to redeem shares for which it has not yet
received good payment; collection of payment may take ten or more days. In such
circumstances, the redemption request will be rejected by the Fund. Once a Fund
has received good payment for the shares a shareholder may submit another
request for redemption.
 
Due to the relatively high costs of handling small investments, each Fund
reserves the right to redeem your shares at net asset value, if, your account in
any Fund has a value of less than the minimum initial purchase amount.
Accordingly, if you purchase shares of any Fund in only the minimum investment
amount, you may be subject to involuntary redemption if you redeem any shares.
Before any Fund exercises its right to redeem such shares you will be given
notice that the value of the shares in your account is less than the minimum
amount and will be allowed 60 days to make an additional investment in such Fund
in an amount which will increase the value of the account to at least the
minimum amount.
 
PURCHASES BY EXCHANGE
 
As permitted pursuant to any rule, regulation or order promulgated by the
Securities and Exchange Commission, shareholders of Investment Class shares of
other funds of the Trust that have similar sales charges may tender their shares
of those Funds for exchange into the number of shares (including fractional
shares) which have a value equal to the total net asset value of shares tendered
divided by the net asset value of Investment Class shares of the Fund next
determined after such order is received. Shares issued pursuant to this offer
will not be subject to the sales charge described above or any other charge. The
Fund may modify or terminate this exchange offer at any time upon 60 days'
notice.
 
PERFORMANCE
 
From time to time, the Funds may advertise yield and total return. These figures
will be based on historical earnings, and are not intended to indicate future
performance. The yield of a Fund refers to the annualized income generated by an
investment in the Fund over a specified 30-day period. The yield is calculated
by assuming that the same amount of income generated by the investment during
that period is generated in each 30-day period over one year and is shown as a
percentage of the investment.
 
The total return of a Fund refers to the average compounded rate of return to a
hypothetical investment, for designated time periods (including, but not limited
to, the period from which the Fund commenced operations through the specified
date), assuming that the entire investment is redeemed at the end of each period
and assuming the reinvestment of all dividend and capital gain distributions.
The total return of a Fund may also be quoted as a dollar amount or on an
aggregate basis, an actual basis, without inclusion of any sales charge, or with
a reduced sales charge in advertisements distributed to investors entitled to a
reduced sales charge.
 
A Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long-term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios,
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they
<PAGE>   185
 
 17
 
relate to fund management, investment philosophy, and investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expense generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to provide a detailed
explanation of the federal, state, or local income tax treatment of a Fund or
its Shareholders. In addition, state and local income tax consequences of an
investment in a Fund may differ from the federal income tax consequences
described below. Accordingly, Shareholders are urged to consult their tax
advisers regarding specific questions as to federal, state and local income
taxes. Additional information concerning taxes is set forth in the Statement of
Additional Information.
 
TAX STATUS OF THE FUNDS:
 
Each Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. Each Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on that part of its net investment company taxable income and
net capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
A Fund will distribute substantially all of its net investment income (including
net short-term capital gain) and net capital gain to Shareholders. Dividends
from a Fund's net investment company taxable income are taxable to Shareholders
as ordinary income, (whether received in cash or in additional shares) to the
extent of the Fund's earnings and profits. Dividends paid by a Fund to corporate
Shareholders will qualify for the dividends received deduction to the extent
derived from dividends received by the Fund from domestic corporations. A
portion of such dividends may be subject to the alternative minimum tax.
Dividends and distributions of net capital gain do not qualify for the
dividends-received deduction and are taxable to Shareholders as long-term
capital gain, regardless of how long Shareholders have held their shares and
regardless of whether the distributions are received in cash or in additional
shares. Each Fund will make annual reports to Shareholders of the federal income
tax status of all distributions, including the amount of dividends eligible for
the dividends-received deduction.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments, a
Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because each Fund distributes
all of its net investment income to its shareholders, a Fund may have to sell
Fund securities to distribute such imputed income, which may occur at a time
when the Advisor would not have chosen to sell such securities and which may
result in a taxable gain or loss.
 
Income derived by a Fund from obligations of foreign issuers may be subject to
foreign
<PAGE>   186
 
 18
 
withholding taxes. A Fund will not be able to treat Shareholders as having paid
their proportionate share of such taxes.
 
Dividends declared by a Fund in October, November, or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
Each Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Investment income received directly by a Fund on direct U.S. obligations is
exempt from tax at the state level and may be exempt, depending on the state,
when received by a Shareholder as income dividends from a Fund provided certain
state-specific conditions are satisfied. Interest received on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. Each Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from a Fund is considered tax exempt in their
particular state.
 
Each sale, exchange, or redemption of Fund Shares is a taxable transaction to
the Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate portfolio of shares and different classes of each fund. In
addition to the Funds, the Trust consists of the following funds: Treasury Money
Market Fund, Money Market Fund, California Tax-Free Money Market Fund,
Intermediate-Term Bond Fund, California Intermediate Tax-Free Bond Fund, Limited
Maturity Government Fund, Blue Chip Growth Fund, Convertible Securities Fund,
Government Securities Fund and International Equity Fund. All consideration
received by the Trust for shares of any fund and all assets of such fund belong
to that fund and would be subject to liabilities related thereto. The Trust
reserves the right to create and issue shares of additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses. Please refer to "Financial Highlights" in this Prospectus
for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings of shareholders, but approval will be sought for certain changes
in the operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon the written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust
<PAGE>   187
 
 19
 
will provide appropriate assistance and information to the Shareholders
requesting the information.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries for the Balanced, Value Momentum and Growth Equity Funds
should be directed to Stepstone Funds, P.O. Box 8416, Boston, Massachusetts
02266-8416. Shareholder inquiries for the Emerging Growth Fund should be
directed to the Administrator, SEI Financial Management Corporation, 680 East
Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of a
Fund is distributed in the form of monthly dividends to Shareholders. Currently,
capital gains of a Fund, if any, will be distributed at least annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares at the net asset value next determined
following the record date, unless the Shareholder has elected to take such
payment in cash. Shareholders may change their election by providing written
notice to the Administrator at least 15 days prior to the change.
 
Dividends and distributions of a Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on Investment Class shares will typically be lower than
dividends payable on Institutional Class shares because of the distribution
expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank, N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Funds:
 
AMERICAN DEPOSITARY RECEIPTS (ADRs)-- ADRs are receipts typically issued by a
U.S. financial institution that evidence ownership of underlying securities
issued by a foreign issuer.
 
CONVERTIBLE BONDS AND CONVERTIBLE PREFERRED STOCK--Convertible Bonds are bonds
convertible into a set number of shares of another form of security (usually
common stock) at a prestated price. Convertible bonds have characteristics
similar to both fixed income and equity securities. Convertible preferred stock
is a class of capital stock that pays dividends at a specified rate and that has
preference over common stock in the payment of dividends and the liquidation of
assets. Convertible preferred stock is preferred stock exchangeable for a given
number of common stock shares, and has characteristics similar to both
fix-income and equity securities. Because of the conversion feature, the market
value of convertible bonds and convertible preferred stock tend to move together
with the market value of the underlying stock. As a result, a Fund's selection
of convertible bonds and convertible preferred stock is based, to a great
extent, on the potential for capital appreciation that
<PAGE>   188
 
 20
 
may exist in the underlying stock. The value of convertible bonds and
convertible preferred stock is also affected by prevailing interest rates, the
credit quality of the issuer and any call provisions.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
FUTURES AND OPTIONS ON FUTURES--Some futures strategies, including selling
futures, buying puts and writing calls, reduce the Fund's exposure to price
fluctuations. Other strategies, including buying futures, writing puts and
buying calls, tend to increase market exposure. Futures and options may be
combined with each other in order to adjust the risk and return characteristics
of the overall portfolio.
 
Options and futures can be volatile instruments, and involve certain risks that
if applied at an inappropriate time, could negatively impact a Fund's return.
 
INVESTMENT GRADE BONDS--Interest-bearing or discounted government or corporate
securities that obligate the issuer to pay the bondholder a specified sum of
money, usually at specific intervals, and to repay the principal amount of the
loan at maturity. Investment grade bonds are those rated BBB or better by S&P or
Baa or better by Moody's.
 
LOAN PARTICIPATIONS--Loan Participations are interests in loans to U.S.
corporations (i.e., borrowers) which are administered by the lending bank or
agent for a syndicate of lending banks, and sold by the lending bank or
syndicate member ("intermediary bank"). In a loan participation, the borrower of
the underlying loan will be deemed to be the issuer of the participation
interest (except to the extent a purchasing Fund derives its rights from the
intermediary bank). Because the intermediary bank does not guarantee a loan
participation in any way, a loan participation is subject to the credit risks
associated with the underlying corporate borrower. In addition, in the event the
underlying corporate borrower fails to pay principal and interest when due, the
Fund may encounter delays, expenses and risks that are greater than those that
would have been involved if the Fund had purchased a direct obligation (such as
commercial paper) of such borrower because it may be necessary under the terms
of the loan participation, for the Fund to assert its rights against the
borrower through the intermediary bank. Moreover, under the terms of a loan
participation, the purchasing Fund may be regarded as a creditor of the
intermediary bank (rather than of the underlying corporate borrower), so that a
Fund may also be subject to the risk that the issuing bank may become insolvent.
Further, in the event of the bankruptcy or insolvency of the corporate borrower,
a loan participation may be subject to certain defenses that can be asserted by
such borrower as a result of improper conduct by the issuing bank. The secondary
market, if any, for these loan participations is limited, and any such
participation purchased by the Fund may be regarded as illiquid.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial paper; and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and
broker-dealers.
 
OPTIONS--Under a call option, the purchaser of the option has the right to
purchase, and the writer
<PAGE>   189
 
 21
 
(the Fund) the obligation to sell, the underlying security at the exercise price
during the option period. A put option gives the purchaser the right to sell,
and the writer the obligation to purchase, the underlying security at the
exercise price during the option period.
 
In addition, each Fund may buy options on stock indices to invest cash on an
interim basis. Such options will be listed on a national securities exchange. In
order to close out an option position, a Fund may enter into a "closing purchase
transaction"--the purchase of an option on the same security with the same
exercise price and expiration date as the option contract previously written on
any particular security. When the security is sold, a Fund effects a closing
purchase transaction so as to close out any existing option on that security.
 
There are risks associated with such investments including the following: (1)
the success of a hedging strategy may depend on the ability of the Advisor or
SubAdvisor to predict movements in the prices of individual securities,
fluctuations in markets and movements in interest rates; (2) there may be an
imperfect correlation between the movement in prices of securities held by a
Fund and the price of options; (3) there may not be a liquid secondary market
for options; and (4) while a Fund will receive a premium when it writes covered
call options, it may not participate fully in a rise in the market value of the
underlying security.
 
REPURCHASE AGREEMENTS--Agreements by which a Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. A Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement. A
Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if the Fund realizes a loss in the sale
of the collateral. A Fund will enter into repurchase agreements only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based on established guidelines. Repurchase agreements are
considered loans under the 1940 Act.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
SECURITIES LENDING--In order to generate additional income, each Fund may lend
the securities in which it is invested, pursuant to agreements requiring that
the loan be continuously secured by cash, securities of the U.S. Government or
its agencies or any combination of cash and such securities as collateral equal
to 100% of the market value at all times of the loaned securities. The lending
Fund will continue to receive interest on the loaned securities while
simultaneously earning interest on the investment of cash collateral. Collateral
is marked to market daily to provide a level of collateral at least equal to the
value of the loaned securities. There may be risks of delay in receiving
additional collateral or risks of delay in recovery of the securities or even
loss of rights in the collateral should the borrower of the securities fail
financially.
 
SECURITIES OF FOREIGN ISSUERS--Securities issued by non-U.S. issuers. There may
be certain risks connected with investing in foreign securities, including risks
of adverse political and economic developments (including possible governmental
seizure or nationalization of assets), the possible imposition of exchange
controls or other governmental restrictions, including less uniformity in
accounting and reporting requirements, the possibility that there will be less
information on
<PAGE>   190
 
 22
 
such securities and their issuers available to the public, the difficulty of
obtaining or enforcing court judgments abroad, restrictions on foreign
investments in other jurisdictions, difficulties in effecting repatriation of
capital invested abroad, and difficulties in transaction settlements and the
effect of delay on shareholder equity. Foreign securities may be subject to
foreign taxes, which reduce yield, and may be less marketable than comparable
U.S. securities. The Fund may be affected favorably or unfavorably by changes in
the exchange rates or exchange control regulations between foreign currencies
and the U.S. dollar. Changes in foreign currency exchange rates may also affect
the value of dividends and interest earned, gains and losses realized on the
sale of securities and net investment income and gains, if any, to distributed
to shareholders by a Fund.
 
STANDARD & POOR'S DEPOSITARY RECEIPTS ("SPDRs")--SPDRs are interests in a unit
investment trust holding a portfolio of securities linked to the S&P 500 Index.
SPDRs closely track the underlying portfolio of securities, trade like a share
of common stock and pay periodic dividends proportionate to those paid by the
portfolio of stocks that constitutes the S&P 500 Index. For further information
regarding the Fund's investment in SPDRs, see the Statement of Additional
Information.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the Federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of such
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date, and no
<PAGE>   191
 
 23
 
interest accrues to a Fund before settlement. These securities are subject to
market fluctuations due to changes, real or anticipated, in market interest
rates and the public's perception of the creditworthiness of the issuer, and
will have the effect of leveraging the Fund's assets. A Fund will establish one
or more segregated accounts with the Custodian, and the Fund will maintain
liquid, high-grade assets in an amount at least equal in value to the Fund's
commitments to purchase when-issued securities.
 
WARRANTS--Securities that entitle the holder to buy a proportionate amount of
common stock at a specified price for a limited or unlimited period of time.
Warrants are often freely transferable and are traded on major stock exchanges.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Investment Class shares of the BLUE CHIP GROWTH FUND (the "Fund"). This summary
is qualified in its entirety by reference to the more detailed information
provided elsewhere in this Prospectus and in the Statement of Additional
Information.
 
WHAT IS THE FUND'S INVESTMENT OBJECTIVE?  The Fund seeks long-term capital
growth by investing in a diversified portfolio of common stocks and other equity
securities of seasoned, large capitalization companies. See "Investment
Objective."
 
WHAT ARE THE FUND'S PERMITTED INVESTMENTS?  The Fund will invest primarily in
equity securities of seasoned, large capitalization companies, which include
common stocks, warrants, ADRs, preferred stocks convertible into common stock,
and units representing combinations of the foregoing. See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUND?  The investment
policies of the Fund entail certain risks and considerations of which an
investor should be aware. Because the Fund invests primarily in equity
securities, the Fund's shares will fluctuate in value with the value of the
underlying securities in its portfolio. Investments in foreign securities may
subject the Fund to different risks than those associated with investments in
securities of U.S. issuers. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's Shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE SUBADVISOR?  Bank of Tokyo-Mitsubishi Trust Company serves as the
SubAdvisor to the Fund. See "The SubAdvisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Institutional and Cash Sweep Class shares of the Trust and the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment is $2,000 ($1,000 for IRAs). A purchase order will be
effective if the Distributor receives an order prior to 4:00 p.m., Eastern time.
Purchase orders for shares will be executed at a per share price equal to the
net asset value next determined after the purchase order is effective (plus any
applicable sales charge). Redemption orders must be placed prior to 4:00 p.m.,
Eastern time on any Business Day for the order to be accepted that day. See
"Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of the Fund is distributed in the form of monthly
dividends to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF THE FUND AND SHOULD
NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES
MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist
the investor in understanding the various costs and expenses that may be
directly or indirectly borne by investors in the Investment Class shares of the
Fund. The Trust also offers Institutional Class shares of the Fund, which are
subject to the same expenses, except there are no sales charges or distribution
costs. Additional information may be found under "The Administrator," "The
Advisor" and "The SubAdvisor."
 
The rules of the Securities and Exchange Commission require that the maximum
sales charge be reflected in the above table. However, certain investors may
qualify for reduced sales charges. See "Purchase and Redemption of Shares."
 
Long-term investors may pay more than the equivalent of the maximum front-end
sales charge otherwise permitted by the Rules of the National Association of
Securities Dealers ("NASD").

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Investment Class shares of the Trust's Blue Chip Growth Fund (the
"Fund"). Information regarding the Trust's other funds is contained in separate
prospectuses that may be obtained from the Trust's Distributor, SEI Financial
Services Company, 680 East Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVE
 
The Blue Chip Growth Fund seeks long-term capital growth by investing in a
diversified portfolio of common stocks and other equity securities of seasoned,
large capitalization companies.
 
There can be no assurance that the Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
Under normal market conditions, at least 65% of the Fund's assets will be
invested in equity securities, which include common stocks, warrants to purchase
common stocks, U.S. dollar denominated equity securities of foreign issuers
traded as American Depositary Receipts ("ADRs"), preferred stocks convertible
into common stocks, and units representing combinations of the foregoing. The
Fund will invest primarily in equity securities of seasoned, large
capitalization companies. A seasoned company is a company with an operating
history of 3 years or more. A large capitalization company is a company with
capitalization in excess of $1.0 billion. The Fund will limit its investment in
foreign securities to 15% of its total assets. A majority of the Fund's equity
investments ordinarily will consist of dividend-paying securities.
 
The balance of the Fund's assets may be invested in money market instruments,
options, futures and options on futures, Standard & Poor's Depositary Receipts
("SPDRs"), shares of other investment companies with similar investment
objectives, investment grade bonds and bonds convertible into common stock. The
aggregate value of options on securities (long puts and calls) may not exceed
10% of the Fund's net assets at the time such options are purchased by the Fund.
The Fund may purchase options on stock indices to invest cash on an interim
basis. The aggregate premium paid on all options on stock indices cannot exceed
20% of the Fund's total assets.
 
The Fund may enter into futures and options on futures only to the extent that
obligations under such contracts or transactions, together with options on
securities, represent not more than 25% of the Fund's assets. The Fund may
purchase securities which have not been registered under the Securities Act of
1933 (Rule 144A Securities). All of the common stocks in which the Fund invests
(including foreign securities in the form of ADRs, but not including Rule 144A
Securities) are traded on registered exchanges or in the over the counter
market.
 
The Fund will restrict its investments in illiquid securities to 15% of its net
assets.
 
The Fund may engage in securities lending and will limit such practice to
33 1/3% of its assets.
 
For temporary defensive purposes during periods when the Advisor or SubAdvisor
determines that market conditions warrant, the Fund may invest up to 100% of its
assets in money market instruments consisting of securities issued or guaranteed
by the U.S. government or its agencies or instrumentalities, receipts, including
TR's, TIGR's and CATS, repurchase agreements, money market funds, certificates
of deposit, time deposits, bank master notes and bankers' acceptances issued by
<PAGE>   197
 
 5
 
banks having net assets of at least 1 billion as of the end of their most recent
fiscal year, commercial paper rated at least A-1 by Standard & Poor's
Corporation ("S&P") or P-1 by Moody's Investors Service, Inc. ("Moody's"), and
in cash. The Fund will not be pursuing its investment objective to the extent
that a substantial portion of its assets are invested in money market
securities.
 
In the event that a security owned by the Fund is downgraded below the stated
ratings categories the Advisor or SubAdvisor will take appropriate action with
regard to the security.
 
Under normal market conditions, the Fund does not expect its portfolio turnover
rate to exceed 75%.
 
For additional information see "Description of Permitted Investments."
 
RISK FACTORS
 
Since the Fund invests primarily in equity securities, the Fund's shares will
fluctuate in value, and thus may be more suitable for long-term investors who
can bear the risk of short-term fluctuations. In addition, the market value of
fixed income securities bears an inverse relationship to changes in market
interest rates, which may affect the net asset value of shares. The longer the
remaining maturity of security, the greater is the effect of interest rate
changes on its market value. Generally, because of their fixed income features,
convertible securities will fluctuate in value to a lesser degree than the
common stocks into which they are convertible. Changes in the value of the
Fund's fixed income securities will not affect cash income received from
ownership of such securities, but will affect the Fund's net asset value.
 
Securities rated BBB by S&P or Baa by Moody's are deemed by these rating
services to have some speculative characteristics, and adverse economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than is the case with higher grade
bonds.
 
Investments in securities of foreign issuers may subject the Fund to different
risks than those attendant to investments in securities of U.S. issuers,
including differences in accounting, auditing and financial reporting standards,
the possibility of expropriation or confiscatory taxation, and political
instability. See "Description of Permitted Investments."
 
INVESTMENT LIMITATIONS
 
The Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the U.S. government or its agencies or instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of a Fund would be invested in the securities of such issuer. This
restriction applies to 75% of the Fund's assets.
 
2. Purchase any securities which would cause more than 25% of the total assets
of a Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies or instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objective and policies; (b) enter into repurchase
agreements; and (c) engage in securities lending as described in this Prospectus
and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.

FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Fund. Fundamental policies cannot be changed with
respect to the Fund without the consent of a majority of the Fund's outstanding
shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor continuously
reviews, supervises and administers the Fund's investment program. The Advisor
discharges its responsibilities subject to the supervision of, and policies
established by, the Trustees of the Trust. The Trust's shares are not sponsored,
endorsed or guaranteed by, and do not constitute obligations or deposits of, the
Advisor and are not guaranteed by the FDIC or any other governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .60% of the average daily net assets of the Fund. The Advisor
may from time to time waive all or a portion of its fee in order to limit the
operating expenses of the Fund. Any such waiver is voluntary and may be
terminated at any time in the Advisor's sole discretion. For the fiscal year
ended January 31, 1996, Union Bank, as predecessor to the Advisor, received .60%
of the average daily net assets of the Fund.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of the Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with, The Bank
of California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE SUBADVISOR
 
The Advisor and Bank of Tokyo-Mitsubishi Trust Company (the "SubAdvisor") have
entered into an investment subadvisory agreement (the "Investment SubAdvisory
Agreement"). Under the Investment SubAdvisory Agreement, the SubAdvisor makes
the day-to-day investment decisions for the assets of the Fund, subject to the
supervision of, and policies established by, the Advisor and the Trustees of the
Trust.
 
Bank of Tokyo-Mitsubishi Trust Company, headquartered at 1251 Avenue of the
Americas, New York, New York 10116, and with offices at 100 Broadway, New York,
New York 10005, operates as a wholly-owned subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd. The SubAdvisor was formed by the combination on April
1,1996, of Bank of Tokyo Trust Company, a wholly-owned subsidiary of The Bank of
Tokyo, Ltd., and Mitsubishi Bank Trust Company of New York, a wholly-owned
subsidiary of The Mitsubishi Bank, Ltd. Bank of Tokyo Trust Company was the
surviving entity, and changed its name to Bank of Tokyo-Mitsubishi Trust
Company. Prior to the combination, subadvisory services were provided by Bank of
Tokyo Trust Company. Bank of Tokyo Trust Company was established in 1955, and
has provided trust services since that time and management services since 1965.
 
The SubAdvisor serves as portfolio manager to bank common funds, employee
benefit funds and personal trust accounts, managing assets in money market,
equity and fixed income portfolios. As of April 1, 1996, the SubAdvisor managed
$750 million in individual portfolios and collective funds. In
<PAGE>   199
 
 7
 
addition, the SubAdvisor also serves as SubAdvisor to the Trust's, Government
Securities, Convertible Securities and Emerging Growth Funds.
 
The SubAdvisor is entitled to a fee, which is calculated daily and paid monthly
out of the Advisor's fee, at an annual rate of .30% of the average daily net
assets of the Fund. For the fiscal year ended January 31, 1996, Bank of Toyko
Trust Company, predecessor of the SubAdvisor, received .30% of the average daily
net assets of the Fund.
 
The day-to-day management of the Blue Chip Growth Fund's investments is the
responsibility of a team of investment professionals.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of the Fund's Investment Class
shares. Any such waiver is voluntary, and may be terminated at any time in the
Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional Class
and Cash Sweep Class shares of the Trust and the Investment Class shares of the
Convertible Securities, Government Securities, Emerging Growth, Blue Chip Growth
and International Equity Funds. Compensation for these services is paid under
the Administration Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days written notice by either party, or upon assignment by the
Distributor.
 
The Investment Class shares have a distribution plan ("Investment Class Plan").
The Distribution Agreement and the Investment Class Plan provides that the
Investment Class shares of the Fund may bear the following distribution
expenses: (1) the cost of prospectuses, reports to Shareholders, sales
literature and other materials for potential investors; (2) advertising; and (3)
expenses incurred in connection with the promotion and sale of the Trust's
shares, including the Distributor's expenses for travel, communication, and
compensation and benefits for sales personnel. In addition, the Trust pays the
Distributor a fee of up to .40% of the Fund's Investment Class shares average
daily net assets, of which a maximum of .25% may be used to compensate
broker/dealers and service providers which provide administrative and/or
distribution services to Investment Class Shareholders or to their other
customers who beneficially own Investment Class shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Fund may be made on days on which
both the New York Stock Exchange and the Federal Reserve wire system are open
for business. ("Business Days"). The minimum initial investment is $2,000
($1,000 for IRAs); however, the minimum investment may be waived in the
Distributors' discretion. All subsequent purchases must be in amounts of at
least $1,000 ($500 for IRAs).
 
Purchase orders for shares will be executed at a per share price equal to the
net asset value next determined after the receipt of the purchase order by the
Distributor (plus any applicable sales
<PAGE>   200
 
 8
 
charge). The purchase price of shares of the Fund is the net asset value next
determined after a purchase order is received and accepted by the Trust (plus a
sales charge). The net asset value per share of the Fund is determined by
dividing the total market value of the Fund's investments and other assets, less
any liabilities, by the total number of outstanding shares of the Fund. Net
asset value per share is determined daily as of 4:00 p.m., Eastern time, on any
Business Day. Purchases will be made in full and fractional shares of the Trust
calculated to three decimal places. The Trust reserves the right to reject a
purchase order when the Distributor determines that it is not in the best
interest of the Trust and/or its Shareholders to accept such order.
 
Shares of the Fund are offered only to residents of states in which the shares
are eligible for purchase.
 
HOW TO PURCHASE THROUGH FINANCIAL INSTITUTIONS
 
Shares may be purchased through financial institutions, including the Adviser,
that provide distribution assistance or shareholder services. Shares purchased
by persons ("Customers") through financial institutions may be held of record by
the financial institution. Financial institutions may impose an earlier cut-off
time for receipt of purchase orders directed through them to allow for
processing and transmittal of these orders to the Transfer Agent for
effectiveness the same day. Customers should contact their financial institution
for information as to that Institution's procedures for transmitting purchase,
exchange or redemption orders to the Trust.
 
Customers who desire to transfer the registration of shares beneficially owned
by them but held of record by a financial institution should contact the
institution to accomplish such change.
 
Depending upon the terms of a particular Customer account, a financial
institution may charge a Customer account fees. Information concerning these
services and any charges will be provided to the Customer by the financial
institution.
 
SALES CHARGES
 
The following table shows the regular sales charge on Investment Class shares to
a "single purchaser" (defined below) together with the dealer discount paid to
dealers and the agency commission paid to brokers (collectively the
"commission"):

</TABLE>
 
The commissions shown in the table apply to sales through authorized dealers and
brokers. Under certain circumstances, the Distributor may use its own funds to
compensate financial institutions and intermediaries in amounts that are in
addition to the commissions shown above. In addition, the Distributor may, from
time to time and at its own expense, provide promotional incentives in the form
of cash or other compensation to certain financial institutions and
intermediaries whose registered representatives have sold or are expected to
sell significant amounts of the Investment Class shares of the Fund. Such other
compensation may take the form of payments for travel expenses, including
lodging, incurred in connection with trips taken by qualifying registered
representatives to places within or without the United States. Under certain
circumstances, commissions up to the amount of the entire sales charge may be
reallowed to dealers or brokers, who might then be deemed to be "underwriters"
under the Securities Act of 1933. Commission rates may vary among the Funds.
 
In calculating the sales charge rates applicable to current purchases of a
Fund's shares, a "single purchaser" is entitled to cumulate current purchases
with the net purchases of previously
<PAGE>   201
 
 9
 
purchased shares of the Fund and other of the Trust's funds (the "Eligible
Funds") which are sold subject to a comparable sales charge.
 
The term "single purchaser" refers to (i) an individual, (ii) an individual and
spouse purchasing shares of the Fund for their own account or for trust or
custodial accounts for their minor children, or (iii) a fiduciary purchasing for
any one trust, estate or fiduciary account, including employee benefit plans
created under Sections 401, 403(b) or 457 of the Internal Revenue Code of 1986,
as amended (the "Code"), including related plans of the same employer. To be
entitled to a reduced sales charge based upon shares already owned, the investor
must ask the Distributor for such entitlement at the time of purchase and
provide the account number(s) of the investor, the investor and spouse, and
their minor children, and give the age of such children. The Fund may amend or
terminate this right of accumulation at any time as to subsequent purchases.
 
LETTER OF INTENT.  By initially investing at least $2,000 and submitting a
Letter of Intent (the "Letter") to the Distributor, a "single purchaser" may
purchase shares of the Fund and the other Eligible Funds during a 13-month
period at the reduced sales charge rates applying to the aggregate amount of the
intended purchases stated in the Letter. The Letter may apply to purchases made
up to 90 days before the date of the Letter. To receive credit for such prior
purchases and later purchases benefitting from the Letter, the Shareholder must
notify the Transfer Agent at the time the Letter is submitted that there are
prior purchases that may apply, and, at the time of later purchases, notify the
Transfer Agent that such purchases are applicable under the Letter.
 
OTHER CIRCUMSTANCES.  No sales charge is imposed on Investment Class shares of
the Fund: (i) issued in plans of reorganization, such as mergers, asset
acquisitions and exchange offers, to which the Trust is a party; (ii) sold to
dealers or brokers that have a sales agreement with the Distributor, for their
own account or for retirement plans for their employees or sold to employees
(and their spouses) of dealers or brokers that certify to the Distributor at the
time of purchase that such purchase is for their own account (or for the benefit
of such employees' minor children); (iii) in aggregate purchases of $1 million
or more by tax-exempt organizations enumerated in Section 501(c) of the Code, or
employee benefit plans created under Sections 401, 403(b) or 457 of the Code;
(iv) sold to employees and families of the Advisor and its affiliates; (v) sold
to fiduciary accounts of the Advisor and its affiliates; or (vi) purchased with
proceeds from the recent redemption of shares of a mutual fund with similar
investment objectives and policies for which a sales load was paid.
 
The waiver of the sales charge under clause (vi) applies only if the following
conditions are met: the purchase must be made within 60 days of the redemption;
the Distributor must be notified in writing by the investor, or his or her
agent, at the time a purchase is made; and a copy of the investor's account
statement showing such redemption must accompany such notice. The waiver policy
with respect to the purchase of shares through the use of proceeds from a recent
redemption above will not continue indefinitely, and may be discontinued at any
time without notice. Investors should contact the Distributor to confirm
continued availability prior to initiating the procedures described in clause
(vi).
 
Shareholders who desire to redeem shares of the Trust must place their
redemption orders prior to 4:00 p.m., Eastern time, on any Business Day for the
order to be accepted on that Business Day. The redemption price is the net asset
value of the Fund next determined after receipt by the Distributor of the
redemption order. Payment on redemption will be made as promptly as possible
and, in any event, within seven calendar days after the redemption order is
received.
 
Payment to shareholders for shares redeemed will be made within seven days after
the Transfer Agent receives the valid redemption request. At various times,
however, a Fund may be requested
<PAGE>   202
 
 10
 
to redeem shares for which it has not yet received good payment; collection of
payment may take ten or more days. In such circumstances, the redemption request
will be rejected by the Fund. Once a Fund has received good payment for the
shares a shareholder may submit another request for redemption.
 
Due to the relatively high costs of handling small investments, each Fund
reserves the right to redeem your shares at net asset value, if, your account in
any Fund has a value of less than the minimum initial purchase amount.
Accordingly, if you purchase shares of any Fund in only the minimum investment
amount you may be subject to involuntary redemption if you redeem any shares.
Before any Fund exercises its right to redeem such shares you will be given
notice that the value of the shares in your account is less than the minimum
amount and will be allowed 60 days to make an additional investment in such Fund
in an amount which will increase the value of the account to at least the
minimum amount.
 
Neither the Transfer Agent nor the Trust will be responsible for any loss,
liability, cost or expense for acting upon wire or telephone instructions that
it reasonably believes to be genuine. The Trust and Transfer Agent will each
employ reasonable procedures to confirm that instructions communicated by
telephone are genuine. Such procedures may includes taping of telephone
conversations.
 
If market conditions are extraordinarily active or other extraordinary
circumstance exist and you experience difficulties placing redemption orders by
telephone, you may consider placing your order by mail.
 
PURCHASES BY EXCHANGE
 
As permitted pursuant to any rule, regulation or order promulgated by the
Securities and Exchange Commission, shareholders of Investment Class Shares of
other funds of the Trust that have similar sales charges may tender their shares
of those Funds for exchange into the number of shares (including fractional
shares) which have a value equal to the total net asset value of shares tendered
divided by the net asset value of Investment Class shares of the Fund next
determined after such order is received. Shares issued pursuant to this offer
will not be subject to the sales charge described above or any other charge. The
Fund may modify or terminate this exchange offer at any time upon 60 days'
notice.
 
PERFORMANCE
 
From time to time, the Fund may advertise yield and total return. These figures
will be based on historical earnings and are not intended to indicate future
performance. The yield of the Fund refers to the annualized income generated by
an investment in the Fund over a specified 30-day period. The yield is
calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year
and is shown as a percentage of the investment.
 
The total return of the Fund refers to the average compounded rate of return to
a hypothetical investment, for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gain
distributions. The total return of the Fund may also be quoted as a dollar
amount or on an aggregate basis, an actual basis, without inclusion of any sales
charge, or with a reduced sales charge in advertisements distributed to
investors entitled to a reduced sales charge.
 
The Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote
<PAGE>   203
 
 11
 
Morningstar, Inc., a service that ranks mutual funds on the basis of
risk-adjusted performance, and Ibbotson Associates of Chicago, Illinois, which
provides historical returns of the capital markets in the U.S. The Fund may use
long-term performance of these capital markets to demonstrate general long-term
risk versus reward scenarios and could include the value of a hypothetical
investment of any of the capital markets. The Fund may also quote financial and
business publications and periodicals as they relate to fund management,
investment philosophy, and investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local income tax treatment of the Fund or
its Shareholders. In addition, state and local income tax consequences of
investing in the Fund may differ from the federal income tax consequences
described below. Accordingly, Shareholders are urged to consult their tax
advisors regarding specific questions as to federal, state and local income
taxes. Additional information concerning taxes is set forth in the Statement of
Additional Information.
 
TAX STATUS OF THE FUND:
 
The Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. The Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so as to be relieved of federal
income tax on that part of its net investment company taxable income and net
capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
The Fund will distribute substantially all of its net investment income
(including net short-term capital gain) and net capital gain to Shareholders.
Dividends from the Fund's net investment company taxable income are taxable to
Shareholders as ordinary income (whether received in cash or in additional
shares) to the extent of the Fund's earnings and profits. Dividends paid by the
Fund to corporate Shareholders will qualify for the dividends received deduction
to the extent derived from dividends received by the Fund from domestic
corporations. A portion of such dividends may be subject to the alternative
minimum tax. Dividends and distributions of net capital gain do not qualify for
the dividends-received deduction and are taxable to Shareholders as long-term
capital gain, regardless of how long Shareholders have held their shares and
regardless of whether the distributions are received in cash or in additional
shares. The Fund will provide annual reports to Shareholders of the federal
income tax status of all distributions, including the amount of dividends
eligible for the dividends-received deduction.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments, a
Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because each Fund distributes
all of its net investment income to its
<PAGE>   204
 
 12
 
shareholders, a Fund may have to sell portfolio securities to distribute such
imputed income, which may occur at a time when the Advisor or SubAdvisor would
not have chosen to sell such securities and which may result in a taxable gain
or loss.
 
Income derived by the Fund from obligations of foreign issuers may be subject to
foreign withholding taxes. The Fund will not be able to treat Shareholders as
having paid their proportionate share of such taxes.
 
Dividends declared by the Fund in October, November, or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
The Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
investment companies.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level, and may be exempt, depending on the state,
when received by a Shareholder as income dividends from the Fund provided
certain state-specific conditions are satisfied. Interest received on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. The Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from the Fund is considered tax exempt in their
particular state.
 
Each sale, exchange, or redemption of Fund Shares is a taxable transaction to
the Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate series of shares and different classes of each fund. In addition
to the Fund, the Trust consists of the following funds: Treasury Money Market
Fund, Money Market Fund, California Tax-Free Money Market Fund, Value Momentum
Fund, Intermediate-Term Bond Fund, Limited Maturity Government Fund, California
Intermediate Tax-Free Bond Fund, Balanced Fund, Growth Equity Fund, Convertible
Securities Fund, Government Securities Fund, Emerging Growth Fund and
International Equity Fund. All consideration received by the Trust for shares of
any fund and all assets of such fund belong to that fund and would be subject to
liabilities related thereto. The Trust reserves the right to create and issue
shares of additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to
<PAGE>   205
 
 13
 
such fund or class. As a Massachusetts business trust, the Trust is not required
to hold annual meetings of shareholders, but approval will be sought for certain
changes in the operation of the Trust and for the election of Trustees under
certain circumstances. In addition, a Trustee may be removed by the remaining
Trustees or by Shareholders at a special meeting called upon the written request
of Shareholders owning at least 10% of the outstanding shares of the Trust. In
the event that such a meeting is requested the Trust will provide appropriate
assistance and information to the Shareholders requesting the information.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of
the Fund is distributed in the form of monthly dividends to Shareholders of
record. Currently, capital gains of the Fund, if any, will be distributed at
least annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares at the net asset value next determined
following the record date, unless the Shareholder has elected to take such
payment in cash. Shareholders may change their election by providing written
notice to the Administrator at least 15 days prior to the change.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on the Investment Class shares will typically be lower
than the dividends payable on the Institutional Class shares because of the
distribution expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank, N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Fund:
 
AMERICAN DEPOSITARY RECEIPTS (ADRs)-- American Depositary Receipts ("ADRs") are
receipts typically issued by a U.S. financial institution that evidence
ownership of underlying securities issued by a foreign issuer.
 
CONVERTIBLE BONDS AND CONVERTIBLE PREFERRED STOCK--Convertible bonds are bonds
convertible into a set number of shares of another form of security (usually
common stock) at a prestated price. Convertible bonds have characteristics
similar to both fixed income and equity securities. Convertible preferred stock
is a class of capital stock that pays dividends at a specified rate and that has
preference over common stock in the payment of dividends and the liquidation of
assets. Convertible preferred stock is preferred stock exchangeable for a given
number of common stock shares, and has characteristics similar to both
fixed-income and equity securities.
<PAGE>   206
 
 14
 
Because of the conversion feature, the market value of convertible bonds and
convertible preferred stock tend to move together with the market value of the
underlying stock. As a result, the Fund's selection of convertible bonds and
convertible preferred stock is based, to a great extent, on the potential for
capital appreciation that may exist in the underlying stock. The value of
convertible bonds is also affected by prevailing interest rates, the credit
quality of the issuer and any call provisions.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
FUTURES AND OPTIONS ON FUTURES--Some futures strategies, including selling
futures, buying puts and writing calls, reduce the Fund's exposure to price
fluctuations. Other strategies, including buying futures, writing puts and
buying calls, tend to increase market exposure. Futures and options may be
combined with each other in order to adjust the risk and return characteristics
of the overall portfolio.
 
Options and futures can be volatile instruments, and involve certain risks that
if applied at an inappropriate time, could negatively impact the Fund's return.
 
INVESTMENT GRADE BONDS--Interest-bearing or discounted government or corporate
securities that obligates the issuer to pay the bondholder a specified sum of
money, usually at specific intervals, and to repay the principal amount of the
loan at maturity. Investment grade bonds are those rated BBB or better by S&P or
Baa or better by Moody's.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial papers and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and
broker-dealers.
 
OPTIONS--Under a call option, the purchaser of the option has the right to
purchase, and the writer (Fund) the obligation to sell, the underlying security
at the exercise price during the option period. A put option gives the
purchasers the right to sell, and the writer the obligation to purchase the
underlying security at the exercise price during the option period.
 
In addition, the Fund may buy options on stock indices to invest cash on an
interim basis. Such options will be listed on a national securities exchange. In
order to close out an option position, the Fund may enter into a "closing
purchase transaction"--the purchase of an option on the same security with the
same exercise price and expiration date as the option contract previously
written on any particular security. When the security is sold the Fund effects a
closing purchase transaction so as to close out any existing option on that
security.
 
There are risks associated with such investments, including the following: (1)
the success of a hedging strategy may depend on the ability of the Advisor or
SubAdvisor to predict movements in the prices of individual securities,
fluctuations in markets and movements in interest rates; (2) there may be an
imperfect correlation between the movement in prices of securities held by the
Fund and the price of options; (3) there may not be a liquid secondary market
for options; and (4) while
<PAGE>   207
 
 15
 
the Fund will receive a premium when it writes covered call options, it may not
participate fully in a rise in the market value of the underlying security.
 
REPURCHASE AGREEMENTS--Agreements by which the Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement.
The Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if the Fund realizes a loss in the sale
of the collateral. A Fund will enter into repurchase agreements only with
financial institutions which are deemed to present minimal risk of bankruptcy
during the term of the agreement based on established guidelines. Repurchase
agreements are considered loans under the 1940 Act.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
SECURITIES LENDING--In order to generate additional income, the Fund may lend
the securities in which it is invested pursuant to agreements requiring that the
loan be continuously secured by cash, securities of the U.S. Government or its
agencies or instrumentalities or any combination of cash and such securities as
collateral equal to 100% of the market value at all times of the loaned
securities. The lending Fund will continue to receive interest on the loaned
securities while simultaneously earning interest on the investment of cash
collateral. Collateral is marked to market daily to provide a level of at least
equal to the market value of the loaned securities. There may be risks of delay
in receiving additional collateral or risks of delay in recovery of the
securities or even loss of rights in the collateral should the borrower of the
securities fail financially.
 
SECURITIES OF FOREIGN ISSUERS--There may be certain risks connected with
investing in foreign securities, including risks of adverse political and
economic developments (including possible governmental seizure or
nationalization of assets), the possible imposition of exchange controls or
other governmental restrictions, including less uniformity in accounting and
reporting requirements, the possibility that there will be less information on
such securities and their issuers available to the public, the difficulty of
obtaining or enforcing court judgments abroad, restrictions on foreign
investments in other jurisdictions, difficulties in effecting repatriation of
capital invested abroad, and difficulties in transaction settlements and the
effect of delay on shareholder equity. Foreign securities may be subject to
foreign taxes, which reduce yield, and may be less marketable than comparable
U.S. securities. The Fund may be affected favorably or unfavorably by changes in
the exchange rates or exchange control regulations between foreign currencies
and the U.S. dollar. Changes in foreign currency exchange rates may also affect
the value of dividends and interest earned, gains and losses realized on the
sale of securities and net investment income and gains, if any, to distributed
to shareholders by the Fund.
 
STANDARD & POOR'S DEPOSITARY RECEIPTS ("SPDRs")--Interests in a unit investment
trust holding a portfolio of securities linked to the S&P 500 Index. SPDRs
closely track the underlying portfolio of securities, trade like a share of
common stock and pay periodic dividends proportionate to those paid by the
portfolio of stocks that constitutes the S&P 500 Index. For further information
regarding the Fund's investment in SPDRs, see the Statement of Additional
Information.
<PAGE>   208
 
 16
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. government, are either backed by the full faith and
credit of the United States or supported by the issuing agencies' right to
borrow from the Treasury.
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component plans
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of such
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
WARRANTS--Securities that entitle the holder to buy a proportionate amount of
common stock at a specified price for a limited or unlimited period of time.
Warrants are often freely transferable and are traded on major stock exchanges.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Investment Class shares of the CALIFORNIA INTERMEDIATE TAX-FREE BOND FUND (the
"Fund"). This summary is qualified in its entirety by reference to the more
detailed information provided elsewhere in this Prospectus and in the Statement
of Additional Information.
 
WHAT IS THE FUND'S INVESTMENT OBJECTIVE?  The Fund seeks to provide high current
income that is exempt from federal and State of California income taxes. See
"Investment Objective."
 
WHAT ARE THE FUND'S PERMITTED INVESTMENTS?  The Fund invests primarily in
investment grade or better bonds and notes issued by the State of California,
its agencies, instrumentalities and political subdivisions, the income on which
is exempt from regular federal and State of California personal income taxes
("California Municipal Securities"). See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUND?  The investment
policies of the Fund entail certain risks and considerations of which an
investor should be aware. Shares of the Fund will fluctuate in value with the
value of the Fund's underlying portfolio securities. Values of fixed income
securities in which the Fund invests tend to vary inversely with interest rates,
and may be affected by other market and economic factors affecting the State of
California as well. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies,
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Fund. See "The Advisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  State Street Bank and Trust Company
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Investment Class shares of the Trust (except for the Convertible
Securities, Government Securities, Emerging Growth, Blue Chip Growth and
International Equity Funds). See "Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business ("Business Days"). The
minimum initial investment is $2,000 ($1,000 for IRAs). A purchase order will be
effective if the Distributor receives an order prior to 4:00 p.m., Eastern time.
Purchase orders for shares will be executed at a per share price equal to the
asset value next determined after the purchase order is effective (plus any
applicable sales charge). Redemption orders must be placed prior to 4:00 p.m.,
Eastern time on any Business Day for the order to be accepted that day. See
"Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of the Fund is distributed in the form of monthly
dividends to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF THE FUND AND SHOULD
NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES
MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist
the investor in understanding the various costs and expenses that may be
directly or indirectly borne by investors in the Investment Class shares of the
Fund. The Trust also offers Institutional Class shares of the Fund which are
subject to the same expenses, except there are no sales charges or distribution
costs. Additional information may be found under "The Administrator" and "The
Advisor."
 
The rules of the Securities and Exchange Commission require that the maximum
sales charge be reflected in the above table. However, certain investors may
qualify for reduced sales charges. See "Purchase and Redemption of Shares."
 
Long-term Shareholders may pay more than the equivalent of the maximum front-end
sales charges otherwise permitted by the Rules of the National Association of
Securities Dealers ("NASD").

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the Funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in sales charges, distribution costs, voting rights
and dividends. Except for these differences among the classes, each share of
each fund represents an equal proportionate interest in that fund. This
Prospectus relates to the Investment Class shares of the Trust's California
Intermediate Tax-Free Bond Fund (the "Fund"). Information regarding the Trust's
other funds is contained in separate prospectuses that may be obtained from the
Trust's Distributor, SEI Financial Services Company, 680 East Swedesford Road,
Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVE
 
The California Intermediate Tax-Free Bond Fund seeks to provide high current
income that is exempt from federal and State of California income taxes.
 
There can be no assurance that the Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
Under normal market conditions, the Fund will invest primarily in bonds and
notes issued by the State of California, its agencies, instrumentalities, and
political sub-divisions, the income on which is exempt from regular federal and
State of California personal income taxes ("California Municipal Securities").
The Fund may also invest in bonds and notes of other states, territories, and
possessions of the U.S. and their agencies, authorities, instrumentalities and
political sub-divisions which are exempt from federal income taxes, and in
shares of other investment companies, specifically money market funds, which
have similar investment objectives.
 
Under normal market conditions, at least 80% of the Fund's assets will be
invested in bonds and notes rated AAA, AA, A or BBB by Standard & Poor's
Corporation ("S&P"), Aaa, Aa, A or Baa by Moody's Investors Service ("Moody's"),
or AAA, AA, A or BBB by Fitch Investors Service ("Fitch") and which pay interest
that is not treated as a preference item for purposes of the federal alternative
maximum tax. The Fund may purchase unrated securities that are determined by the
Advisor to be of comparable quality at the time of purchase pursuant to quality
standards set by the Board of Trustees. In the event that a security owned by
the Fund is downgraded below the stated ratings categories, the Advisor will
take appropriate action with regard to the security.
 
Under California law, a mutual fund must have at least 50% of its total assets
invested in California Municipal Securities at the end of each quarter of its
taxable year in order to be eligible to pay California residents dividends that
are wholly or partially exempt from California personal income taxes.
Accordingly, the Fund intends to maintain at least 65% of its assets in
California Municipal Securities and may invest up to 100% of its assets in such
securities.
 
The Fund has no restrictions on the maturity of municipal securities in which it
may invest. The dollar-weighted average portfolio maturity of the Fund will be
from three to ten years. Accordingly, the Fund seeks to invest in municipal
securities of such maturities which, in the judgment of the Advisor, will
provide a high level of current income consistent with prudent investment, with
consideration given to market conditions.
 
The Fund may purchase securities on a forward commitment or a when-issued basis
where such purchases are for investment and not for leveraging purposes;
however, the Fund may sell these securities before the settlement date if it is
deemed advisable. No additional forward
<PAGE>   215
 
 6
 
commitments will be made if more than 20% of the Fund's net assets would be so
committed.
 
The Fund may invest in securities which have not been registered under the
Securities Act of 1933 (Rule 144A Securities). The Fund will restrict its
investment in illiquid securities to 15% of its net assets.
 
CALIFORNIA MUNICIPAL SECURITIES
 
The two principal classifications of California Municipal Securities are
"general obligation" and "revenue" bonds. General obligation bonds are secured
by the issuer's pledge of its full faith, credit, and taxing power for the
payment of principal and interest. Revenue bonds are payable only from the
revenues derived from a particular facility or class of facilities or, in some
cases, from the proceeds of a special excise tax or other specific revenue
source. Private activity bonds (formerly known as industrial revenue bonds) are
generally revenue bonds.
 
Certain California Municipal Securities are municipal lease revenue obligations
(or certificates of participation or "COPs"), which typically provide that the
municipality has no obligation to make lease or installment payments in future
years unless money is appropriated for such purpose. While the risk of
non-appropriation is inherent to COP financing, this risk is mitigated by the
Fund's policy to invest in COPs that are rated in one of the four highest rating
categories used by Moody's, S&P, or Fitch.
 
California Municipal Securities also include so-called Mello-Roos and assessment
district bonds, which are usually unrated instruments issued to finance the
building of roads and other public works and projects that are primarily secured
by real estate taxes levied on property located in the local community. Most of
these bonds do not seek agency ratings because the issues are too small, and in
most cases, the purchase of these bonds are based upon the Advisor's
determination that it is suitable for the Fund.
 
The Fund may also purchase, subject to a limit of 15% of its assets, California
Municipal Securities that are variable rate demand notes (or VRDNs).
 
For temporary defensive purposes during periods when the Advisor determines that
market conditions warrant, the Fund may invest up to 25% of its assets in
taxable money market instruments consisting of securities issued or guaranteed
by the U.S. Government, its agencies or instrumentalities, receipts, including
TR's, TIGR's and CATS, money market funds, repurchase agreements, and commercial
paper rated at least A-1 by S&P, or P-1 by Moody's, or Fitch-1 by Fitch. The
Fund also may hold a portion of its assets in cash. The Fund will not be
pursuing its investment objective to the extent that a substantial portion of
its assets is invested in money market securities, and the Fund may pay taxable
dividends to shareholders as a result.
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
The ability of the State of California and its political sub-divisions to raise
money through property taxes and to increase spending has been the subject of
considerable debate and various constitutional initiatives and other
limitations. This process, and associated legal challenges, remains on-going. It
is not possible to predict the ultimate effect of these constitutional
initiatives, nor can there be any assurance that additional initiatives will not
be introduced in the coming years.
 
The market value of the Fund's fixed income investments will change in response
to interest rate changes and other factors. During periods of falling interest
rates, the values of outstanding fixed income securities generally rise.
Conversely, during periods of rising interest rates, the values of such
securities generally decline. Changes by recognized rating agencies in the
rating of any fixed income security and in the ability of an issuer to make
payments of interest and principal also affect the value of these investments.
Changes in the value of fund securities will not affect cash
<PAGE>   216
 
 7
 
income derived from these securities, but will affect the Fund's net asset
value.
 
Securities rated BBB by S&P or Fitch or Baa by Moody's are deemed by these
rating services to have some speculative characteristics, and adverse economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than is the case with higher grade
bonds.
 
INVESTMENT LIMITATIONS
 
The Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the United States or its agencies and instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of the Fund would be invested in the securities of such issuer provided,
however, that the Fund may invest up to 25% of its total assets without regard
to this restriction as permitted by applicable law.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies and instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objective and policies; and (b) enter into
repurchase agreements.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Fund. Fundamental policies cannot be changed with
respect to the Fund without the consent of a majority of the Fund's outstanding
shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of the Fund and continuously reviews,
supervises and administers the Fund's investment program. The Advisor discharges
its responsibilities subject to the supervision of, and policies established by,
the Trustees of the Trust. The Trust's shares are not sponsored, endorsed or
guaranteed by, and do not constitute obligations or deposits of, the Advisor and
are not guaranteed by the FDIC or any other governmental agency.
 
Under the Advisory Agreement, the Advisor is entitled to a fee, which is
calculated daily and paid monthly, at an annual rate of .50% of the average
daily net assets of the Fund. The Advisor may from time to time waive all or a
portion of its fee in order to limit the operating expenses of the Fund. Any
such waiver is voluntary and may be terminated at any time in the Advisor's sole
discretion.
 
For the fiscal year ended January 31, 1996, Union Bank, predecessor of the
Advisor, was paid an advisory fee of .03% of the average daily net assets of the
Fund.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of the Fund. On April 1,
1996, Union Bank, the Trust's then-investment
<PAGE>   217

advisor, combined with The Bank of California, N.A., and the resulting bank
changed its name to Union Bank of California, N.A. At the same time, the banks'
investment management divisions were combined. Each of Union Bank and The Bank
of California, N.A., (or its predecessor bank) has been in banking since the
early 1900's and historically, each has had significant investment functions
within its trust and investment division. Union Bank of California, N.A., is a
subsidiary of The Bank of Tokyo-Mitsubishi, Ltd.
 
Robert Bigelow has served as team leader of the Fund since October, 1994. Prior
to joining the Advisor's predecesser, Union Bank, in June, 1994, Mr. Bigelow
served as a portfolio manager at City National Bank from January, 1986 to June,
1994.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement dated January 30, 1991 (the "Administration
Agreement"). Under the terms of the Administration Agreement, the Administrator
provides the Trust with certain management services including all necessary
office space, equipment, personnel, and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of the Fund's Investment Class
shares. Any such waiver is voluntary, and may be terminated at any time in the
Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
State Street Bank and Trust Company serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Investment Class
shares of the Trust (except for the Convertible Securities, Government
Securities, Emerging Growth, Blue Chip Growth and International Equity Funds).
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days written notice by either party, or upon assignment by the
Distributor.
 
The Investment Class shares have a distribution plan ("Investment Class Plan").
The Distribution Agreement and the Investment Class Plan provide that the
Investment Class shares of the Fund may bear the following distribution
expenses: (1) the cost of prospectuses, reports to shareholders, sales
literature and other materials for potential investors; (2) advertising; and (3)
expenses incurred in connection with the promotion and sale of the Trust's
shares, including the Distributor's expenses for travel, communication, and
compensation and benefits for sales personnel. In addition, the Trust pays the
Distributor a fee of up to .40% of the Fund's Investment Class shares average
daily net assets, of which a maximum of .25% may be used to compensate
broker/dealers and service providers which provide administrative and/or
distribution services to Investment Class Shareholders or to their other
customers who beneficially own Investment Class shares.
 
HOW TO PURCHASE SHARES
 
GENERAL INFORMATION
 
Purchases and redemptions of shares of the Fund may be made on days on which
both the New York
<PAGE>   218
 
 9
 
Stock Exchange and the Federal Reserve wire system are open for business.
("Business Days"). The minimum initial investment is $2,000 ($1,000 for IRAs);
however, the minimum investment may be waived in the Distributor's discretion.
All subsequent purchases must be at least $1,000 ($500 for IRAs).
 
Purchase orders for shares will be executed at a per share price equal to the
net asset value next determined after the receipt of the purchase order by the
Distributor (plus any applicable sales charge). The purchase price of shares of
the Fund is the net asset value next determined after a purchase order is
received and accepted by the Trust (plus a sales charge). The net asset value
per share of the Fund is determined by dividing the total market value of the
Fund's investments and other assets, less any liabilities, by the total number
of outstanding shares of the Fund. Net asset value per share is determined daily
as of 4:00 p.m., Eastern time, on any Business Day. Purchases will be made in
full and fractional shares of the Trust calculated to three decimal places. The
Trust reserves the right to reject a purchase order when the Distributor
determines that it is not in the best interest of the Trust and/or its
Shareholders to accept such order.
 
Shares of the Fund are offered only to residents of states in which the shares
are eligible for purchase.
 
HOW TO PURCHASE BY MAIL
 
You may purchase shares of the Fund by completing and signing an Account
Application form and mailing it, along with a check (or other negotiable bank
instrument or money order) payable to "Stepstone Funds (Fund Name)," to the
Transfer Agent at P.O. Box 8416, Boston, Massachusetts 02266-8416. All purchases
made by check should be in U.S. dollars and made payable to the "Stepstone Funds
(Fund Name)." Third party checks, credit card checks or cash will not be
accepted. You may purchase more shares at any time by mailing payment also to
the Transfer Agent at the above address. Orders placed by mail will be executed
on receipt of your payment. If your check does not clear, your purchase will be
canceled and you could be liable for any losses or fees incurred.
 
You may obtain Account Application Forms by calling the Distributor at
1-800-734-2922.
 
HOW TO PURCHASE BY WIRE
 
You may purchase shares by wiring Federal funds, provided that your Account
Application has been previously received. You must wire funds to the Transfer
Agent and the wire instructions must include your account number. You must call
the Transfer Agent at 1-800-734-2922 before wiring any funds. An order to
purchase shares by Federal funds wire will be deemed to have been received by
the Fund on the Business Day of the wire; provided that the shareholder wires
funds to the Transfer Agent prior to 4:00 p.m., Eastern time, if the Transfer
Agent does not receive the wire by 4:00 p.m., Eastern time, the order will be
executed on the next Business Day.
 
HOW TO PURCHASE THROUGH AN AUTOMATIC
INVESTMENT PLAN ("AIP")
 
You may arrange for periodic additional investments in the Fund through
automatic deductions by Automated Clearing House ("ACH") from a checking account
by completing this section in the Account Application form. The minimum
pre-authorized investment amount is $100 per month. The AIP is available only
for additional investments to an existing account.
 
HOW TO PURCHASE THROUGH FINANCIAL INSTITUTIONS
 
Shares may be purchased through financial institutions, including the Adviser,
that provide distribution assistance or shareholder services. Shares purchased
by persons ("Customers") through financial institutions may be held of record by
the financial institution. Financial institutions may impose an earlier cut-off
time for receipt of purchase orders directed through them to allow for
processing and transmittal of these orders to the Transfer Agent for
effectiveness the same day.
<PAGE>   219

Customers should contact their financial institution for information as to that
institution's procedures for transmitting purchase, exchange or redemption
orders to the Trust.
 
Customers who desire to transfer the registration of shares beneficially owned
by them but held of record by a financial institution should contact the
institution to accomplish such change.
 
Depending upon the terms of a particular Customer account, a financial
institution may charge a Customer account fees. Information concerning these
services and any charges will be provided to the Customer by the financial
institution.
 
SALES CHARGES
 
The following table shows the regular sales charge on Investment Class shares to
a "single purchaser" (defined below), together with the dealer discount paid to

</TABLE>
 
- ---------------
*  A contingent deferred sales charge of 1.00% will be assessed against any
   proceeds of any redemption of such Investment Class shares prior to one year
   from date of purchase.
 
The commissions shown in the table apply to sales through authorized dealers and
brokers. Under certain circumstances, the Distributor may use its own funds to
compensate financial institutions and intermediaries in amounts that are
additional to the commissions shown above. In addition, the Distributor may,
from time to time and at its own expense, provide promotional incentives in the
form of cash or other compensation to certain financial institutions and
intermediaries whose registered representatives have sold or are expected to
sell significant amounts of the Investment Class shares of the Fund. Such other
compensation may take the form of payments for travel expenses, including
lodging, incurred in connection with trips taken by qualifying registered
representatives to places within or without the United States. Under certain
circumstances, commissions up to the amount of the entire sales charge may be
reallowed to dealers or brokers, who might then be deemed to be "underwriters"
under the Securities Act of 1933. Commission rates may vary among the Funds.
 
In calculating the sales charge rates applicable to current purchases of a
Fund's shares, a "single purchaser" is entitled to cumulate current purchases
with net purchases of previously purchased shares of the Fund and other of the
Trust's funds (the "Eligible Funds") which are sold subject to a comparable
sales charge.
 
The term "single purchaser" refers to (i) an individual, (ii) an individual and
spouse purchasing shares of the Fund for their own account or for trust or
custodial accounts for their minor children, or (iii) a fiduciary purchasing for
any one trust, estate or fiduciary account, including employee benefit plans
created under Sections 401, 403(b) or 457 of the Internal Revenue Code of 1986,
as amended (the "Code"), including related plans of the same employer. To be
entitled to a reduced sales charge based upon shares already owned, the investor
must ask the Distributor for such entitlement at the time of purchase and
provide the account number(s) of the investor, the investor and spouse, and
their minor children, and give the age of such children. The Fund may amend or
terminate this right of accumulation at any time as to subsequent purchases.
 
LETTER OF INTENT.  By initially investing at least $2,000 and submitting a
Letter of Intent (the "Letter") to the Distributor, a "single purchaser" may
purchase shares of the Fund and the other Eligible Funds during a 13-month
period at the reduced sales charge rates applying to the aggregate amount of the
intended purchases stated in the Letter. The Letter may apply to
<PAGE>   220
 
 11
 
purchases made up to 90 days before the date of the Letter. To receive credit
for such prior purchases and later purchases benefitting from the Letter, the
Shareholder must notify the Transfer Agent at the time the Letter is submitted
that there are prior purchases that may apply, and, at the time of later
purchases, notify the Transfer Agent that such purchases are applicable under
the Letter.
 
RIGHTS OF ACCUMULATION.  In calculating the sales charge rates applicable to
current purchases of Investment Class shares, a "single purchaser" is entitled
to cumulate current purchases with the current market value of previously
purchased Investment Class shares of the Fund sold subject to a comparable sales
charge.
 
To exercise your right of accumulation based upon shares you already own, you
must ask the Distributor for this reduced sales charge at the time of your
additional purchase and provide the account number(s) of the investor, as
applicable, the investor and spouse, and their minor children. The Fund may
amend or terminate this right of accumulation at any time as to subsequent
purchases.
 
WAIVER OF SALES LOAD.  No sales charge is imposed on Investment Class shares of
the Fund: (i) issued in plans of reorganization, such as mergers, asset
acquisitions and exchange offers, to which the Trust is a party; (ii) sold to
dealers or brokers that have a sales agreement with the Distributor, for their
own account or for retirement plans for their employees or sold to employees
(and their spouses) of dealers or brokers that certify to the Distributor at the
time of purchase that such purchase is for their own account (or for the benefit
of such employees' minor children); (iii) in aggregate purchases of $1 million
or more by tax-exempt organizations enumerated in Section 501(c) of the Code, or
employee benefit plans created under Sections 401, 403(b) or 457 of the Code;
(iv) sold to employees and families of the Advisor and its affiliates; (v) sold
to fiduciary accounts of the Advisor and its affiliates; or (vi) purchased with
proceeds from the recent redemption of shares of a mutual fund with similar
investment objectives and policies for which a sales charge was paid.
 
The waiver of the sales charge under circumstance (vi) above applies only if the
purchase is made within 60 days of the redemption and if conditions imposed by
the Distributor are met. This waiver policy with respect to the purchase of
shares through the use of proceeds from a recent redemption as described in
circumstance (vi) above will not be continued indefinitely, and may be
discontinued at any time without notice. Investors should contact the
Distributor to determine whether they are eligible to purchase shares without
paying a sales charge through the use of proceeds from a recent redemption as
described above and to confirm continued availability of this waiver policy
prior to initiating the procedures described in circumstance (vi).
 
REDEMPTION OF SHARES
 
You may redeem your shares without charge on any Business Day. There is,
however, a $15 charge for wiring redemption proceeds to a shareholder's
designated account. Shares may be redeemed by mail, by telephone or through a
pre-arranged systematic withdrawal plan. Investors who own shares held by a
financial institution should contact that institution for information on how to
redeem shares.
 
BY MAIL
 
A written request for redemption must be received by the Transfer Agent, P.O.
Box 8416, Boston, Massachusetts 02266-8416 in order to constitute a valid
redemption request.
 
If the redemption request exceeds $5,000, or if the request directs the proceeds
to be sent or wired to an address different from that of record, the Transfer
Agent may require that the signature on the written redemption request be
guaranteed. You should be able to obtain a signature guarantee from a bank,
broker, dealer, credit union, securities exchange or association, clearing
agency or savings association. Notaries public cannot guarantee

signatures. The signature guarantee requirement will be waived if all of the
following conditions apply: (1) the redemption is for not more than $5,000 worth
of shares, (2) the redemption check is payable to the shareholder(s) of record,
and (3) the redemption check is mailed to the shareholder(s) at his or her
address of record.
 
BY TELEPHONE
 
You may redeem your shares by calling the Transfer Agent at 1-800-734-2922.
Under most circumstances, payments will be transmitted on the next Business Day
following receipt of a valid request or redemption. You may have the proceeds
mailed to your address or wired to a commercial bank account previously
designated on your Account Application. There is no charge for having redemption
proceeds mailed to you, but there is a $15 charge for wiring redemption
proceeds.
 
You may request a wire redemption for redemptions in excess of $500 by calling
the Transfer Agent at 1-800-734-2922 who will deduct a wire charge of $15 from
the amount of the wire redemption. Shares cannot be redeemed by Federal Reserve
wire on Federal holidays restricting wire transfers.
 
Neither the Transfer Agent nor the Trust will be responsible for any loss,
liability, cost or expense for acting upon wire or telephone instructions that
it reasonably believes to be genuine. The Trust and Transfer Agent will each
employ reasonable procedures to confirm that instructions, communicated by
telephone are genuine. Such procedures may include taping of telephone
conversations.
 
If market conditions are extraordinarily active or other extraordinary
circumstance exist, and you experience difficulties placing redemption orders by
telephone, you may consider placing your order by mail.
 
SYSTEMATIC WITHDRAWAL PLAN ("SWP")
 
The Fund offers a Systematic Withdrawal Plan ("SWP"), which you may use to
receive regular distributions from your account. Upon commencement of the SWP,
your account must have a current net asset value of $5,000 or more. You may
elect to receive automatic payments via check or ACH of $100 or more on a
monthly, quarterly, semi-annual or annual basis. You may arrange to receive
regular distributions from your account via check or ACH by completing this
section in the Account Application form.
 
To participate in the SWP, you must have your dividends automatically
reinvested. You should realize that if your automatic withdrawals exceed income
dividends, your invested principal in the account will be depleted. Thus,
depending on the frequency and amounts of the withdrawal payments and/or any
fluctuations in the net asset value per share, your original investment could be
exhausted entirely. You may change or cancel the SWP at any time on written
notice to the Transfer Agent. The Transfer Agent may require that the signature
on the written notice be guaranteed.
 
It is generally not in your best interest to be participating in the SWP at the
same time that you are purchasing additional shares if you have to pay a sales
load in connection with such purchases.
 
OTHER INFORMATION REGARDING REDEMPTIONS.
 
Shareholders who desire to redeem shares of the Trust must place their
redemption orders prior to 4:00 p.m., Eastern time, on any Business Day for the
order to be accepted on that Business Day. The redemption price is the net asset
value of the Fund next determined after receipt by the Distributor of the
redemption order. Payment on redemption will be made as promptly as possible
and, in any event, within seven calendar days after the redemption order is
received.
 
Payment to shareholders for shares redeemed will be made within seven days after
the Transfer Agent receives the valid redemption request. At various times,
however, a Fund may be requested to redeem shares for which it has not yet
received good payment; collection of payment may take ten or more days. In such
circumstances, the redemption request will be rejected by the Fund. Once a Fund
has received good payment for the
<PAGE>   222
 
 13
 
shares a shareholder may submit another request for redemption.
 
Due to the relatively high costs of handling small investments, each Fund
reserves the right to redeem your shares at net asset value, if, your account in
any Fund has a value of less than the minimum initial purchase amount.
Accordingly, if you purchase shares of any Fund in only the minimum investment
amount, you may be subject to involuntary redemption if you redeem any shares.
Before any Fund exercises its right to redeem such shares you will be given
notice that the value of the shares in your account is less than the minimum
amount and will be allowed 60 days to make an additional investment in such Fund
in an amount which will increase the value of the account to at least the
minimum amount.
 
PURCHASES BY EXCHANGE
 
As permitted pursuant to any rule, regulation or order promulgated by the
Securities and Exchange Commission, shareholders of Investment Class shares of
other Funds of the Trust that have similar sales charge schedules may tender
their shares of those Funds for exchange into the number of shares (including
fractional shares) which have a value equal to the total net asset value of
shares tendered divided by the net asset value of Investment Class shares of the
Fund next determined after such order is received. Shares issued pursuant to
this offer will not be subject to the sales charge described above or any other
charge. The Fund may modify or terminate this exchange offer at any time upon 60
days' notice.
 
PERFORMANCE
 
From time to time, the Fund may advertise yield and total return. These figures
will be based on historical earnings and are not intended to indicate future
performance. The yield of the Fund refers to the annualized income generated by
an investment in the Fund over a specified 30-day period. The yield is
calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year,
and is shown as a percentage of the investment.
 
The total return of the Fund refers to the average compounded rate of return to
a hypothetical investment for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gain
distributions. The total return of the Fund may also be quoted as a dollar
amount or on an aggregate basis, an actual basis, without inclusion of any sales
charge, or with a reduced sales charge in advertisements distributed to
investors entitled to a reduced sales charge.
 
The Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long-term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising, and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark
<PAGE>   223
 
 14
 
correlation indicate how valid a comparative benchmark might be. Measures of
volatility and correlation are calculated using averages of historical data and
cannot be calculated precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to provide a detailed
explanation of the federal, state, or local income tax treatment of the Fund or
its Shareholders. In addition, state and local tax consequences of an investment
in the Fund may differ from the federal income tax consequences described below.
Accordingly, Shareholders are urged to consult their tax advisors regarding
specific questions as to federal, state and local income taxes. Additional
information concerning taxes is set forth in the Statement of Additional
Information.
 
TAX STATUS OF THE FUND:
 
The Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. The Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on that part of its net investment company taxable income and
net capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
The Fund will distribute all of its net investment income (including net
short-term capital gain) to Shareholders. If, at the close of each quarter of
its taxable year, at least 50% of the value of the Fund's assets consists of
obligations the interest on which is excludable from gross income, the Fund may
pay "exempt-interest dividends" to its Shareholders. Those dividends constitute
the portion of the aggregate dividends as designated by the Fund, equal to the
excess of the excludable interest over certain amounts disallowed as deductions.
Exempt-interest dividends are excludable from a Shareholder's gross income for
federal income tax purposes, but may have certain collateral federal income tax
consequences, including alternative minimum tax. Additional information
concerning taxes is set forth in the Statement of Additional Information.
 
Current federal tax law limits the types and volume of bonds qualifying for the
federal income tax exemption of interest, which may have an effect on the
ability of the Fund to purchase sufficient amounts of tax-exempt securities to
satisfy the Code's requirements for the payment of "exempt-interest" dividends.
 
Any dividends paid out of income realized by the Fund on taxable securities will
be taxable to Shareholders as ordinary income, whether received in cash or in
additional shares, to the extent of the Fund's earnings and profits and will not
qualify for the dividends received deductions for corporate shareholders.
 
Distributions of net capital gain also do not qualify for the dividends-received
deduction and are taxable to shareholders as long-term capital gain, regardless
of how long a Shareholder has held Fund shares, and regardless of whether the
distributions are received in cash or in additional shares. The Fund will make
annual reports to Shareholders of the federal income tax status of all
distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments,
the Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because the Fund
<PAGE>   224
 
 15
 
distributes all of its net investment income to shareholders, the Fund may have
to sell Fund securities to distribute such imputed income, which may occur at a
time when the Advisor would not have chosen to sell such securities and which
may result in a taxable gain or loss.
 
Dividends declared by the Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared if paid by the Fund any time during the following January.
 
The Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level, and may be exempt, depending on the state,
when received by a Shareholder as income dividends from the Fund provided
certain state-specific conditions are satisfied. Interest received on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. The Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from the Fund is considered tax exempt in their
particular state.
 
Each sale, exchange, or redemption of Fund shares is a taxable transaction to
the Shareholder.
 
Furthermore, entities or persons who are "substantial users" (or persons related
to "substantial users") of facilities financed by "private activity bonds" or
"industrial development bonds" should consult their tax advisors before
purchasing shares. (See the Statement of Additional Information.)
 
CALIFORNIA TAXES:
 
The Fund intends to qualify to pay dividends to Shareholders that are exempt
from California personal income tax ("California exempt-interest dividends").
The Fund will qualify to pay California exempt-interest dividends if (1) at the
close of each quarter of the Fund's taxable year, at least 50 percent of the
value of the Fund's total assets consists of obligations the interest on which
would be exempt from California personal income tax if the obligations were held
by an individual ("California Tax Exempt Obligations") and (2) the Fund
continues to qualify as a regulated investment company.
 
If the Fund qualifies to pay California exempt-interest dividends, dividends
distributed to Shareholders will be considered California exempt-interest
dividends (1) if they are designated as exempt-interest dividends by the Fund in
a written notice to Shareholders mailed within 60 days of the close of the
Fund's taxable year and (2) to the extent the interest received by the Fund
during the year on California Tax Exempt Obligations exceeds expenses of the
Fund that would be disallowed under California personal income tax law as
allocable to tax-exempt interest if the Fund were an individual. If the
aggregate dividends so designated exceed the amount that may be treated as
California exempt-interest dividends, only that percentage of each dividend
distribution equal to the ratio of aggregate California exempt-interest
dividends to aggregate dividends so designated will be treated as a California
exempt-interest dividend. The Fund will notify Shareholders of the amount of
California exempt-interest dividends each year.
 
Corporations subject to California franchise tax that invest in the Fund may not
be entitled to exclude California exempt-interest dividends from income.
 
Dividend distributions that do not qualify for treatment as California
exempt-interest dividends will be taxable to Shareholders at ordinary income tax
rates for California personal income tax
<PAGE>   225
 
 16
 
purposes to the extent of the Fund's earnings and profits.
 
Interest on indebtedness incurred or continued by a Shareholder in connection
with the purchase of shares of the Fund will not be deductible for California
personal income tax purposes if the Fund distributes California exempt-interest
dividends.
 
The foregoing is a general, abbreviated summary of certain of the provisions of
the California Revenue and Taxation Code presently in effect as they directly
govern the taxation of Shareholders subject to California personal income tax.
These provisions are subject to change by legislative or administrative action,
and any such change may be retroactive with respect to Fund transactions.
Shareholders are advised to consult with their own tax advisors for more
detailed information concerning California tax matters.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate series of shares and different classes of each fund. In addition
to the Fund, the Trust consists of the following funds: Treasury Money Market
Fund, Money Market Fund, California Tax-Free Money Market Fund, Growth Equity
Fund, Value Momentum Fund, Limited Maturity Government Fund, Balanced Fund,
Intermediate-Term Bond Fund, Blue Chip Growth Fund, Emerging Growth Fund,
Convertible Securities Fund, Government Securities Fund and International Equity
Fund. All consideration received by the Trust for shares of any fund and all
assets of such fund belong to that fund, and would be subject to liabilities
related thereto. The Trust reserves the right to create and issue shares of
additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses. Please refer to "Financial Highlights" in this prospectus
for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings, but approval will be sought for certain changes in the
operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon the written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate
assistance and information to the Shareholders requesting the meeting in
connection with such matters.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.

SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to Stepstone Funds, P.O. Box 8416,
Boston, Massachusetts 02266-8416.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of
the Fund is distributed in the form of monthly dividends to Shareholders of
record. Currently, capital gains of the Fund, if any, will be distributed at
least annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares at the net asset value next determined
following the record date, unless the Shareholder has elected to take such
payment in cash. Shareholders may change their election by providing written
notice to the Administrator at least 15 days prior to the change.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on Investment Class shares will typically be lower than
dividends payable on Institutional Class shares because of the distribution
expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank, N.A. Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Fund:
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term, debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial paper; and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and
broker-dealers.
 
MUNICIPAL FORWARDS--Municipal Forwards are forward commitments for the purchase
of tax-exempt bonds with a specified coupon to be delivered by an issuer at a
future date, typically exceeding 45 days but normally less than one year after
the commitment date. Municipal forwards are normally used as a refunding
mechanism for bonds that may only be redeemed on a designated future date. As
with forward commitments and when-issued securities, municipal forwards are
subject to market fluctuations due to changes, real or anticipated, in market
interest rates between the
<PAGE>   227
 
 18
 
commitment date and the settlement date and will have the effect of leveraging
the Fund's assets. Municipal forwards may be considered to be illiquid
investments. The Fund will maintain liquid, high-grade securities in a
segregated account in an amount at least equal to the purchase price of the
municipal forward.
 
MUNICIPAL SECURITIES--Municipal securities consist of (i) debt obligations
issued by or on behalf of public authorities to obtain funds to be used for
various public facilities, for refunding outstanding obligations, for general
operating expenses and for lending such funds to other public institutions and
facilities, and (ii) certain private activity and industrial development bonds
issued by or on behalf of public authorities to obtain funds to provide for the
construction, equipment, repair or improvement of privately operated facilities.
Municipal notes include general obligation notes, tax anticipation notes,
revenue anticipation notes, bond anticipation notes, certificates of
indebtedness, demand notes and construction loan notes. Municipal bonds include
general obligation bonds, revenue or special obligation bonds, private activity
and industrial development bonds. General obligation bonds are backed by the
taxing power of the issuing municipality. Revenue bonds are backed by the
revenues of a project or facility, tolls from a toll bridge, for example. The
payment of principal and interest on private activity and industrial development
bonds generally is dependent solely on the ability of the facility's user to
meet its financial obligations and the pledge, if any, of real and personal
property so financed as security for such payment.
 
PARTICIPATION INTERESTS--Participation interests are interests in municipal
securities from financial institutions such as commercial and investment banks,
savings and loan associations and insurance companies. These interests may take
the form of participations, beneficial interests in a trust, partnership
interests or any other form of indirect ownership that allows the Fund to treat
the income from the investment as exempt from federal income tax. The Fund
invests in these participation interests in order to obtain credit enhancement
or demand features that would not be available through direct ownership of the
underlying Municipal Securities.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
REPURCHASE AGREEMENTS--Agreements by which the Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement.
The Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its right to
dispose of the collateral securities or if the Fund realizes a loss on the sale
of the collateral. The Fund will enter into a repurchase agreement only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based on established guidelines. Repurchase agreements are
considered loans under the 1940 Act.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
<PAGE>   228
 
 19
 
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury
and separately traded interest and principal component parts of such obligations
that are transferable through the Federal book-entry system known as Separately
Traded Registered Interest and Principal Securities ("STRIPS").
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's"), "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. California
Municipal Securities may also be acquired through the purchase of municipal
forwards. The interest rates on these securities may be reset daily, weekly,
quarterly or some other reset period, and may have a floor or ceiling on
interest rate changes. There is a risk that the current interest rate on such
obligations may not accurately reflect existing market interest rates. A demand
instrument with a demand notice period exceeding seven days may be considered
illiquid if there is no secondary market for such security.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Investment Class shares of the LIMITED MATURITY GOVERNMENT FUND (the "Fund").
This summary's qualified in its entirety by reference to the more detailed
information provided elsewhere in this Prospectus and in the Statement of
Additional Information.
 
WHAT IS THE FUND'S INVESTMENT OBJECTIVE?  The Fund seeks a high level of income
and relative price stability consistent with safety of capital. See "Investment
Objective."
 
WHAT ARE THE FUND'S PERMITTED INVESTMENTS?  The Fund will invest at least 65% of
its assets in U.S. Treasury notes and other direct obligations of the U.S.
Treasury, and obligations issued or guaranteed by U.S. Government agencies or
instrumentalities, including mortgage-backed securities issued or guaranteed by
U.S. Government agencies such as the Government National Mortgage Association
("GNMA"), the Federal National Mortgage Association ("FNMA"), or the Federal
Home Loan Mortgage Corporation ("FHLMC"). See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUND?  The investment
policies of the Fund entail certain risks and considerations of which an
investor should be aware. There can be no assurance that the Fund will achieve
its investment objective. The Fund's investments are subject to market and
interest rate fluctuations which may affect the value of the Fund's shares.
During periods of falling interest rates, the values of outstanding fixed income
securities generally rise. Conversely, during periods of rising interest rates,
the values of such securities generally decline. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies,
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in sales charges, distribution costs, voting rights
and dividends. Except for these differences among the classes, each share of
each fund represents an equal proportionate interest in that fund. This
Prospectus relates to the Investment Class shares of the Trust's Limited
Maturity Government Fund (the "Fund"). Information regarding the Trust's other
funds is contained in separate prospectuses that may be obtained from the
Trust's Distributor, SEI Financial Services Company, 680 East Swedesford Road,
Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVE
 
The Limited Maturity Government Fund seeks a high level of income, relative to
funds with like investment objectives, and relative price stability consistent
with safety of capital.
 
There can be no assurance that the Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
The Fund will invest at least 65% of its assets in U.S. Treasury notes, other
direct obligations of the U.S. Treasury, and obligations issued or guaranteed by
U.S. Government agencies or instrumentalities, including mortgage-backed
securities issued or guaranteed by U.S. Government agencies such as GNMA, FNMA
or FHLMC.
 
With respect to its remaining assets, the Fund may invest in: restricted
securities which have not been registered under the Securities Act of 1933 (Rule
144A Securities); receipts, including TR's, TIGR's and CATS; certificates of
deposit, time deposits and bankers' acceptances issued or guaranteed by United
States banks with assets of at least $1 billion, including comparable U.S.
dollar denominated obligations of foreign branches of such banks; privately
issued mortgage-backed securities; money market funds; repurchase agreements
involving securities that constitute permissible investments for the Fund; and
Federal funds.
 
The Fund will not invest more than 15% of its assets in illiquid securities. The
Trust considers Federal funds investments maturing in more than 7 days to be
illiquid. In addition, the Fund may engage in securities lending. The Fund will
limit such practice to 33 1/3% of total assets.
 
The Fund may purchase securities on a forward commitment or when-issued basis
where such purchases are for investment and not for leveraging purposes;
however, the Fund may sell these securities before the settlement date if it is
deemed advisable. No additional forward commitments will be made if more than
20% of the Fund's net assets would be so committed.
 
Guarantees of the Fund's securities by the U.S. Government or its agencies or
instrumentalities guarantee only the principal and interest on the guaranteed
securities, and do not guarantee the securities' yield or the yield or value of
the Fund's shares.
 
Under normal circumstances, the Fund will maintain an average weighted maturity
of three years or less. The measure of average maturity will use the expected
life of securities held by the Fund.
 
The Advisor will seek to enhance the yield of the Fund by taking advantage of
yield disparities or other factors that occur in the government securities and
money markets. The Fund may dispose of any security prior to its maturity if
such disposition and reinvestment of the proceeds are expected to enhance yield
consistent with the Advisor's judgment as to a desirable maturity
<PAGE>   235
 
 6
 
structure or if such disposition is believed to be advisable due to other
circumstances or considerations.
 
Mortgage-backed securities purchased by the Fund will be issued or guaranteed as
to payment of principal and interest by the United States government or its
agencies or instrumentalities or, if issued by private issuers, rated in one of
the two highest rating categories by a nationally recognized rating agency. The
principal governmental issuer or guarantors of mortgage-backed securities are
the GNMA, FNMA, and FHLMC. Obligations of GNMA are backed by the full faith and
credit of the United States Government, while obligations of FNMA and FHLMC are
supported by the respective agency only. The Fund may purchase mortgage-backed
securities that are backed or collateralized by fixed, adjustable or floating
rate mortgages.
 
Mortgage-backed securities that are not issued or guaranteed by the United
States Government or its agencies or instrumentalities, including securities
nominally issued by a governmental entity (such as the Resolution Trust
Corporation), are not obligations of a governmental entity, and thus may bear a
risk of nonpayment. The timely payment of principal and interest normally is
supported, at least partially, by various forms of insurance or guarantees.
There can be no assurance, however, that such credit enhancements will support
full payment of the principal and interest on such obligations.
 
The portfolio turnover rate for the Fund for the fiscal year ended January 31,
1996 was 186%. This rate of portfolio turnover may result in higher brokerage
execution costs and higher levels of capital gains.
 
For temporary defensive purposes when the Adviser determines that market
conditions warrant, the Fund may invest up to 100% of its assets in money market
instruments consisting of securities issued or guaranteed by the U.S.
government, its agencies or instrumentalities, repurchase agreements, receipts,
including TR's, TIGR's and CATS, certificates of deposit, time deposits, bank
master notes and bankers' acceptances issued by banks having net assets of at
least $1 billion as of the end of its most recent fiscal year or rated at least
A-1 by Standard & Poor's Corporation ("S&P") or P-1 by Moody's Investor Services
("Moody's"), and in cash. To the extent that the Fund is engaged in temporary
defensive investing, it will not be pursuing its investment objective.
 
For additional information, see "Description of Permitted Investments."
 
ELIGIBILITY UNDER FEDERAL CREDIT
UNION ACT
 
The Fund is limited to making investments and engaging in investment
transactions that are permissible for federal credit unions. Therefore, the Fund
will not invest in zero coupon securities with maturities greater than 10 years.
All collateralized mortgage obligations ("CMOs") and real estate mortgage
investment conduits ("REMICs") purchased by the Fund will comport with the
average life, average life sensitivity and price sensitivity tests of Section
703.5(g) of the National Credit Union Association's ("NCUA") Rules and
Regulations. The Fund may purchase stripped mortgage-backed securities ("SMBS"),
residual interests in CMOs or REMICs, or non-floating/adjustable rate CMOs or
REMICs that do not comport with Section 703.5(g) of the NCUA Rules and
Regulations only if the instrument is purchased to reduce the Fund's interest
rate risk and is subjected to the monitoring, reporting, evaluation and pricing
requirements of Section 703.5(i) of the NCUA Rules and Regulations. Floating or
adjustable rate CMOs or REMICs that do not comply with Section 703.5(g) may be
purchased by the Fund if, they comport with the provisions of Section 703.5(j)
of the NCUA Rules and Regulations.
 
Shares of the Fund are designed to qualify as eligible investments for federally
chartered credit unions pursuant to Section 107(7), 107(8) and 107(15) of the
Federal Credit Union Act and Part 703 of the NCUA Rules and Regulations. The
Fund will continually monitor changes in the applicable laws, rules and
regulations governing eligible investments, including new investments, for
<PAGE>   236
 
 7
 
federally chartered credit unions and will take such action as may be necessary
to assure that the Fund's investments, and, therefore, shares of the Fund,
continue to qualify as eligible investments under the Federal Credit Union Act.
 
Sections 107(7), 107(8) and 107(15) of the Federal Credit Union Act set forth
those securities, deposits and other obligations in which federally chartered
credit unions may invest. The Fund's investments consist exclusively of assets
designed to qualify as eligible investments if owned directly by a federally
chartered credit union. Shares of the Fund may or may not qualify as eligible
investments for particular state chartered credit unions. Accordingly, the Fund
encourages, but does not require, each state chartered credit union to consult
qualified legal counsel concerning whether the Fund's shares are permissible
investments for that credit union. While the Advisor will ensure that the Fund
follows investment policies set forth herein, the Fund cannot be responsible for
compliance by participating state chartered credit unions with limitations on
permissible investments to which they may be subject.
 
RISK FACTORS
 
The market value of the Fund's fixed income investments will change in response
to interest rate changes and other factors. During periods of falling interest
rates, the values of outstanding fixed income securities generally rise.
Conversely, during periods of rising interest rates, the values of such
securities generally decline. Securities with longer maturities are subject to
greater fluctuations in value than securities with shorter maturities. Changes
by recognized agencies in the rating of any fixed income security, and in the
ability of an issuer to make payments of interest and principal, also affect the
value of these investments. Changes in the value of Fund securities will not
affect cash income derived from these securities, but will affect the Fund's net
asset value.
 
Mortgage-backed securities are subject to prepayment of the underlying
mortgages. During periods of declining interest rates, prepayment of mortgages
underlying these securities can be expected to accelerate. When the mortgage-
backed securities held by a Fund are prepaid, the Fund must reinvest the
proceeds in securities, the yields of which reflect prevailing interest rates,
which may be lower than those of the prepaid security.
 
Some of the permitted investments for the Fund may not be permitted investments
for particular state chartered credit unions. See "The Trust."
 
INVESTMENT LIMITATIONS
 
The Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the United States, its agencies or instrumentalities and repurchase agreements
involving such securities) if as a result more than 5% of the total assets of
the Fund would be invested in the securities of such issuer. This restriction
applies to 75% of the Fund's assets.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies and instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industry as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objectives and policies, and (b) enter into
repurchase agreements.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental
<PAGE>   237

and non-fundamental investment limitations are set forth in the Statement of
Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Fund. Fundamental policies cannot be changed with
respect to the Fund without the consent of a majority of the Fund's outstanding
shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of the Fund and continuously reviews,
supervises and administers the Fund's investment program. The Advisor discharges
its responsibilities subject to the supervision of, and policies established by,
the Trustees of the Trust. The Trust's shares are not sponsored, endorsed or
guaranteed by, and do not constitute obligations or deposits of, the Advisor and
are not guaranteed by the FDIC or any other government agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .30% of the average daily net assets of the Fund. The Advisor
may from time to time waive all or a portion of its fees in order to limit the
operating expenses of the Fund. Any such waiver is voluntary, and may be
terminated at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, the Fund paid Union Bank, as
predecessor to the Advisor, an advisory fee of .30% of its average daily net
assets.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of the Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
Martin Standish has served as team leader of the Fund since its inception. Mr.
Standish is a Vice President of the Advisor, and has been with the Advisor and
its predecessor, Union Bank, since June, 1992. Prior to his employment with the
Advisor and its predecessor, Union Bank, Mr. Standish served as a portfolio
manager at Patterson Capital from November, 1991 to June, 1992 and at Pacific
Century Advisors from February, 1990 to November, 1991. He earned his M.B.A. at
the University of Texas at Dallas from 1989 to 1991 and has a B.S. in Finance
from Colorado State University.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
Administration Agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10%
<PAGE>   238
 
 9
 
of assets over $2 billion. The Administrator may waive its fee or reimburse
various expenses to the extent necessary to limit the total operating expenses
of the Fund's Investment Class shares. Any such waiver is voluntary, and may be
terminated at any time in the Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
State Street Bank and Trust Company serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Investment Class
shares of the Trust (except for the Convertible Securities, Government
Securities, Emerging Growth, Blue Chip Growth and International Equity Funds).
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution is renewable annually and may be terminated by the
Distributor, by a majority vote of the Disinterested Trustees or by a majority
vote of the outstanding securities of the Trust upon not more than 60 days
written notice by either party, or upon assignment by the Distributor.
 
The Investment Class shares have a distribution plan (the "Investment Class
Plan"). The Distribution Agreement and the Investment Class Plan provide that
the Investment Class shares of the Fund may bear the following distribution
expenses: (1) the cost of prospectuses, reports to Shareholders, sales
literature and other materials for potential investors; (2) advertising; and (3)
expenses incurred in connection with the promotion and sale of the Trust's
shares, including the Distributor's expenses for travel, communication, and
compensation and benefits for sales personnel. In addition, the Trust pays the
Distributor a fee of up to .40% of the Fund's Investment Class shares average
daily net assets, of which a maximum of .25% may be used to compensate
broker/dealers and service providers, which provide administrative and/or
distribution services to Investment Class Shareholders or to their other
customers.
 
HOW TO PURCHASE SHARES
 
GENERAL INFORMATION
 
Purchases and redemptions of shares of the Fund may be made on days on which
both the New York Stock Exchange and the Federal Reserve wire system are open
for business ("Business Days"). The minimum initial investment in the Trust is
$2,000 ($1,000 for IRAs); however, the minimum investment may be waived at the
Distributor's discretion. All subsequent purchases must be at least $1,000 ($500
for IRAs).
 
Purchase orders for shares will be executed at a per share price equal to the
net asset value next determined after the receipt of the purchase order by the
Distributor. The purchase price of shares of the Fund is the net asset value
next determined after a purchase order is received and accepted by the Trust.
The net asset value per share of the Fund is determined by dividing the total
market value of the Fund's investments and other assets, less any liabilities,
by the total number of outstanding shares of the Fund. Net asset value per share
is determined daily as of 4:00 p.m., Eastern time, on any Business Day.
Purchases will be made in full and fractional shares of the Trust calculated to
three decimal places. The Trust reserves the right to reject a purchase order
when the Distributor determines that it is not in the best interest of the Trust
and/or its Shareholders to accept such order.
 
Shares of the Fund are offered only to residents of states in which the shares
are eligible for purchase.
 
HOW TO PURCHASE BY MAIL
 
You may purchase shares of the Fund by completing and signing an Account
Application form and mailing it, along with a check (or other negotiable bank
instrument or money order) payable to "Stepstone Funds (Fund Name)," to the
Transfer Agent at P.O. Box 8416, Boston, Massachusetts 02266-8416. All purchases
made
<PAGE>   239
 
 10
 
by check should be in U.S. dollars and made payable to the "Stepstone Funds
(Fund Name)." Third party checks, credit card checks or cash will not be
accepted. You may purchase more shares at any time by mailing payment also to
the Transfer Agent at the above address. Orders placed by mail will be executed
on receipt of your payment. If your check does not clear, your purchase will be
canceled and you could be liable for any losses or fees incurred.
 
You may obtain Account Application Forms by calling the Distributor at
1-800-734-2922.
 
HOW TO PURCHASE BY WIRE
 
You may purchase shares by wiring Federal funds, provided that your Account
Application has been previously received. You must wire funds to the Transfer
Agent and the wire instructions must include your account number. You must call
the Transfer Agent at 1-800-734-2922 before wiring any funds. An order to
purchase shares by Federal funds wire will be deemed to have been received by
the Fund on the Business Day of the wire, provided that the shareholder wires
funds to the Transfer Agent prior to 4:00 p.m., Eastern time, if the Transfer
Agent does not receive the wire by 4:00 p.m., Eastern time, the order will be
executed on the next Business Day.
 
HOW TO PURCHASE THROUGH AN AUTOMATIC INVESTMENT PLAN ("AIP")
 
You may arrange for periodic additional investments in the Fund through
automatic deductions by Automated Clearing House ("ACH") from a checking account
by completing this section in the Account Application form. The minimum
pre-authorized investment amount is $100 per month. The AIP is available only
for additional investments to an existing account.
 
HOW TO PURCHASE THROUGH FINANCIAL INSTITUTIONS
 
Shares may be purchased through financial institutions, including the Advisor,
that provide distribution assistance or shareholder services. Shares purchased
by persons ("Customers") through financial institutions may be held of record by
the financial institution. Financial institutions may impose an earlier cut-off
time for receipt of purchase orders directed through them to allow for
processing and transmittal of these orders to the Transfer Agent for
effectiveness the same day. Customers should contact their financial institution
for information as to that institution's procedures for transmitting purchase,
exchange or redemption orders to the Trust.
 
Customers who desire to transfer the registration of shares beneficially owned
by them but held of record by a financial institution should contact the
institution to accomplish such change.
 
Depending upon the terms of a particular Customer account, a financial
institution may charge a Customer account fees. Information concerning these
services and any charges will be provided to the Customer by the financial
institution.
 
SALES CHARGES
 
The following table shows the regular sales charge on Investment Class shares to
a "single purchaser" (described below) together with the dealer discount paid to
dealers and the agency commission paid to brokers (collectively the

The commissions shown in the table apply to sales through authorized dealers and
brokers. Under
<PAGE>   240
 
 11
 
certain circumstances, the Distributor may use its own funds to compensate
financial institutions and intermediaries in amounts that are additional to the
commissions shown above. In addition, the Distributor may, from time to time and
at its own expense, provide promotional incentives in the form of cash or other
compensation to certain financial institutions and intermediaries whose
registered representatives have sold or are expected to sell significant amounts
of the Investment Class shares of the Fund. Such other compensation may take the
form of payments for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives to places within or
without the United States. Under certain circumstances, commissions up to the
amount of the entire sales charge may be reallowed to dealers or brokers, who
might then be deemed to be "underwriters" under the Securities Act of 1933.
Commission rates may vary among the Funds.
 
In calculating the sales charge rates applicable to current purchases of a
Fund's shares, a "single purchaser" is entitled to cumulate current purchases
with the net purchases of previously purchased shares of the Fund and other of
the Trust's funds (the "Eligible Funds") which are sold subject to a comparable
sales charge.
 
The term "single purchaser" refers to (i) an individual, (ii) an individual and
spouse purchasing shares of the Fund for their own account or for trust or
custodial accounts for their minor children, or (iii) a fiduciary purchasing for
any one trust, estate or fiduciary account, including employee benefit plans
created under Sections 401, 403(b) or 457 of the Internal Revenue Code of 1986,
as amended (the "Code"), including related plans of the same employer. To be
entitled to a reduced sales charge based upon shares already owned, the investor
must ask the Distributor for such entitlement at the time of purchase and
provide the account number(s) of the investor, the investor and spouse, and
their minor children, and give the age of such children. The Fund may amend or
terminate this right of accumulation at any time as to subsequent purchases.
 
LETTER OF INTENT. By initially investing at least $2,000 and submitting a Letter
of Intent (the "Letter") to the Distributor, a "single purchaser" may purchase
shares of the Fund and the other Eligible Funds during a 13 month period at the
reduced sales charge rates applying to the aggregate amount of the intended
purchases stated in the Letter. The Letter may apply to purchases made up to 90
days before the date of the Letter. To receive credit for such prior purchases
and later purchases benefitting from the Letter, the Shareholder must notify the
Transfer Agent at the time the Letter is submitted that there are prior
purchases that may apply, and, at the time of later purchases, notify the
Transfer Agent that such purchases are applicable under the Letter.
 
RIGHTS OF ACCUMULATION.  In calculating the sales charge rates applicable to
current purchases of Investment Class shares, a "single purchaser" is entitled
to cumulate current purchases with the current market value of previously
purchased Investment Class shares of the Fund sold subject to a comparable sales
charge.
 
To exercise your right of accumulation based upon shares you already own, you
must ask the Distributor for this reduced sales charge at the time of your
additional purchase and provide the account number(s) of the investor, as
applicable, the investor and spouse, and their minor children. The Fund may
amend or terminate this right of accumulation at any time as to subsequent
purchases.
 
WAIVER OF SALES LOAD.  No sales charge is imposed on Investment Class shares of
the Fund: (i) issued in plans of reorganization, such as mergers, asset
acquisitions and exchange offers, to which the Trust is a party; (ii) sold to
dealers or brokers that have a sales agreement with the Distributor, for their
own account or for retirement plans for prior employees or sold to employees
(and their spouses) of dealers or brokers that certify to the Distributor at the
time of purchase that such purchase is for their own account (or for the benefit
of such employees' minor children):
<PAGE>   241
 
 12
 
(iii) in aggregate purchases of $1 million or more by tax-exempt organizations
enumerated in Section 501(c) of the Code, or employee benefit plans created
under Section 401, 403(b) or 457 of the Code; (iv) sold to employees and
families of the Advisor and its affiliates; (v) sold to fiduciary accounts of
the Advisor and its affiliates; or (vi) purchased with proceeds from the recent
redemption of shares of a mutual fund with similar investment objectives and
policies for which a sales charge was paid.
 
The waiver of the sales changes under clause (vi) applies only if the following
conditions are met: the purchase must be made within 60 days of the redemption;
the Distributor must be notified in writing by the investors, or his or her
agent, at the time a purchase is made; and a copy of the investor's account
statement showing such redemption must accompany such notice. The waiver policy
with respect to the purchase of shares through the use of proceeds from a recent
redemption above will not continue indefinitely and may be discontinued at any
time without notice. Investors should contact the Distributor to confirm
continued availability prior to initiating the procedures described in clause
(vi).
 
REDEMPTION OF SHARES
 
You may redeem your shares without charge on any Business Day. There is,
however, a $15 charge for wiring redemption proceeds to a shareholder's
designated account. Shares may be redeemed by mail, by telephone or through a
pre-arranged systematic withdrawal plan. Investors who own shares held by a
financial institution should contact that institution for information on how to
redeem shares.
 
BY MAIL
 
A written request for redemption must be received by the Transfer Agent, P.O.
Box 8416, Boston, Massachusetts 02266-8416 in order to constitute a valid
redemption request.
 
If the redemption request exceeds $5,000, or if the request directs the proceeds
to be sent or wired to an address different from that of record, the Transfer
Agent may require that the signature on the written redemption request be
guaranteed. You should be able to obtain a signature guarantee from a bank,
broker, dealer, credit union, securities exchange or association, clearing
agency or savings association. Notaries public cannot guarantee signatures. The
signature guarantee requirement will be waived if all of the following
conditions apply: (1) the redemption is for not more than $5,000 worth of
shares, (2) the redemption check is payable to the shareholder(s) of record, and
(3) the redemption check is mailed to the shareholder(s) at his or her address
of record.
 
BY TELEPHONE
 
You may redeem your shares by calling the Transfer Agent at 1-800-734-2922.
Under most circumstances, payments will be transmitted on the next Business Day
following receipt of a valid request or redemption. You may have the proceeds
mailed to your address or wired to a commercial bank account previously
designated on your Account Application. There is no charge for having redemption
proceeds mailed to you, but there is a $15 charge for wiring redemption
proceeds.
 
You may request a wire redemption for redemptions in excess of $500 by calling
the Transfer Agent at 1-800-734-2922 who will deduct a wire charge of $15 from
the amount of the wire redemption. Shares cannot be redeemed by Federal Reserve
wire on Federal holidays restricting wire transfers.
 
Neither the Transfer Agent nor the Trust will be responsible for any loss,
liability, cost or expense for acting upon wire or telephone instructions that
it reasonably believes to be genuine. The Trust and Transfer Agent will each
employ reasonable procedures to confirm that instructions, communicated by
telephone are genuine. Such procedures may include taping of telephone
conversations.
<PAGE>   242
 
 13
 
If market conditions are extraordinarily active or other extraordinary
circumstance exist, and you experience difficulties placing redemption orders by
telephone, you may consider placing your order by mail.
 
SYSTEMATIC WITHDRAWAL PLAN ("SWP")
 
The Fund offers a Systematic Withdrawal Plan ("SWP"), which you may use to
receive regular distributions from your account. Upon commencement of the SWP,
your account must have a current net asset value of $5,000 or more. You may
elect to receive automatic payments via check or ACH of $100 or more on a
monthly, quarterly, semi-annual or annual basis. You may arrange to receive
regular distributions from your account via check or ACH by completing this
section in the Account Application form.
 
To participate in the SWP, you must have your dividends automatically
reinvested. You should realize that if your automatic withdrawals exceed income
dividends, your invested principal in the account will be depleted. Thus,
depending on the frequency and amounts of the withdrawal payments and/or any
fluctuations in the net asset value per share, your original investment could be
exhausted entirely. You may change or cancel the SWP at any time on written
notice to the Transfer Agent. The Transfer Agent may require that the signature
on the written notice be guaranteed.
 
It is generally not in your best interest to be participating in the SWP at the
same time that you are purchasing additional shares if you have to pay a sales
load in connection with such purchases.
 
OTHER INFORMATION REGARDING REDEMPTIONS.
 
Shareholders who desire to redeem shares of the Fund must place their redemption
orders prior to 4:00 p.m., Eastern time, on any Business Day for the order to be
accepted on that Business Day. The redemption price is the net asset value of
the Fund next determined after receipt by the Distributor of the redemption
order. Payment on redemption will be made as promptly as possible and, in any
event, within seven calendar days after the redemption order is received.
 
Payment to shareholders for shares redeemed will be made within seven days after
the Transfer Agent receives the valid redemption request. At various times,
however, a Fund may be requested to redeem shares for which it has not yet
received good payment; collection of payment may take ten or more days. In such
circumstances, the redemption request will be rejected by the Fund. Once a Fund
has received good payment for the shares a shareholder may submit another
request for redemption.
 
Due to the relatively high costs of handling small investments, each Fund
reserves the right to redeem your shares at net asset value, if, your account in
any Fund has a value of less than the minimum initial purchase amount.
Accordingly, if you purchase shares of any Fund in only the minimum investment
amount, you may be subject to involuntary redemption if you redeem any shares.
Before any Fund exercises its right to redeem such shares you will be given
notice that the value of the shares in your account is less than the minimum
amount and will be allowed 60 days to make an additional investment in such Fund
in an amount which will increase the value of the account to at least the
minimum amount.
 
PURCHASES BY EXCHANGE
 
As permitted pursuant to any rule, regulation or order promulgated by the
Securities and Exchange Commission, shareholders of Investment Class shares of
other Funds of the Trust that have sales charges may tender their shares for
those Funds for exchange into the number of shares (including fractional shares)
which have a value equal to the total net asset value of shares tendered divided
by the net asset value of Investment Class shares of the Fund next determined
after such order is received. Shares issued pursuant to this offer will not be
subject to this sales charge described above or any other charge. The Fund may
modify or terminate this exchange offer at any time upon 60 days' notice.
<PAGE>   243

PERFORMANCE
 
From time to time, the Fund may advertise yield and total return. These figures
will be based on historical earnings, and are not intended to indicate future
performance. The yield of the Fund refers to the annualized income generated by
an investment in the Fund over a specified 30-day period. The yield is
calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year,
and is shown as a percentage of the investment.
 
The total return of the Fund refers to the average compounded rate of return to
a hypothetical investment, for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gain
distributions. The total return of the Fund may also be quoted as a dollar
amount or on an aggregate basis, an actual basis, without inclusion of any sales
charge, or with a reduced sales charge in advertisements distributed to
investors entitled to a reduced sales charge.
 
The Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Fund may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising, and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark, while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial, or
administrative action. No attempt has been made to present a detailed
explanation of the federal, state, or local income tax treatment of the Fund or
its Shareholders. In addition, state and local tax consequences of an investment
in the Fund may differ from the federal income tax consequences discussed below.
Accordingly, Shareholders are urged to consult their tax advisers regarding
specific questions as to federal, state, and local income taxes. Additional
information concerning taxes is set forth in the Statement of Additional
Information.
 
TAX STATUS OF THE FUND:
 
The Fund is treated as a separate entity for federal income tax purposes, and is
not combined with the Trust's other Funds. The Fund intends to qualify for the
special tax treatment afforded regulated investment companies by the Internal
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on that part of its net investment company taxable income and
net capital gain (the excess of net long-term
<PAGE>   244
 
 15
 
capital gain over net short-term capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
The Fund will distribute all of its net investment income (including net
short-term capital gain) to Shareholders. Dividends from the Fund's net
investment company taxable income are taxable to Shareholders as ordinary income
(whether received in cash or in additional shares) to the extent of the Fund's
earnings and profits. Any net capital gains will be distributed at least
annually, and will be taxed to Shareholders as long-term capital gains,
regardless of how long the Shareholder has held shares and regardless of whether
the distributions are received in cash or in additional shares. Dividends and
distributions of capital gain do not qualify for the corporate
dividends-received deduction for corporate shareholders. The Fund will provide
annual reports to Shareholders of the federal income tax status of all
distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments,
the Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations on such obligations during that period. Because the
Fund distributes all of its net investment income to shareholders, the Fund may
have to sell Fund securities to distribute such imputed income which may occur
at a time when the Advisor would not have chosen to sell such securities, and
which may result in a taxable gain or loss.
 
Dividends declared by the Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared if paid by the Fund any time during the following January.
 
The Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level when received directly by the Fund, and may
be exempt, depending on the state, when received by a Shareholder as income
dividends from the Fund provided certain state-specific conditions are
satisfied. Interest realized on repurchase agreements collateralized by U.S.
government obligations normally is not exempt from state tax. The Fund will
inform Shareholders annually of the percentage of income and distributions
derived from direct U.S. Treasury obligations. Shareholders should consult their
tax advisors to determine whether any portion of the income dividends received
from the Fund is considered tax exempt in their particular state.
 
Each sale, exchange, or redemption of Fund shares is a taxable event to the
Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts Business Trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate series of shares and different classes of each fund. In addition
to the Fund, the Trust consists of the following funds: Treasury Money Market
Fund, Money Market Fund, California Tax-Free Money Market Fund, Growth Equity
Fund, Value Momentum Fund, Balanced Fund, Intermediate-Term Bond Fund,
California Intermediate Tax-Free Bond Fund, Blue Chip Growth Fund, Emerging
Growth Fund, Convertible Securities Fund, Government Securities Fund and
International Equity Fund. All consideration received by the Trust for shares of
any fund and all assets of such fund belong to that fund, and would be subject
to liabilities related thereto. The Trust reserves the right to create and issue
shares of additional funds.
<PAGE>   245
 
 16
 
The Trust pays its expenses, including fees of its service providers, audit and
legal expenses, expenses of preparing prospectuses, proxy solicitation material
and reports to shareholders, costs of custodial services and registering the
shares under Federal and State securities laws, pricing, insurance expenses,
litigation and other extraordinary expenses, brokerage costs, interest charges,
taxes and organization expenses. Please refer to "Financial Highlights" in this
prospectus for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to that fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings of shareholders, but approval will be sought for certain changes
in the operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide appropriate
assistance and information to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semi-annually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to Stepstone Funds, P.O. Box 8416,
Boston, Massachusetts 02266-8416.
 
DIVIDENDS
 
On each Business Day, the Fund declares a dividend from net investment income
(not including capital gain) as of the close of trading on the New York Stock
Exchange (generally 4:00 p.m. Eastern time) to shareholders of record at the
previous net asset value calculation. Dividends are normally paid (and, where
applicable, reinvested) on the first Business Day of the following month.
Currently capital gains of the Fund, if any, will be distributed at least
annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares, unless the Shareholder has elected to take
such payment in cash. Shareholders may change their election by providing
written notice to the Administrator at least 15 days prior to the distribution.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on the Investment Class shares will typically be lower
than the dividends payable on the Institutional Class shares because of the
distribution expenses charged on Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.

CUSTODIAN
 
CoreStates Bank, N.A., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian"), acts as Custodian of the Trust. The
Custodian holds cash, securities and other assets of the Trust as required by
the Investment Company Act of 1940, as amended (the "1940 Act").
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Fund:
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
FEDERAL FUNDS--Federal funds are funds held by a regional Federal Reserve Bank
for the account of a bank ("Fed Bank") that is a member of such Federal Reserve
Bank. A loan of Federal funds is an unsecured loan at a negotiated interest rate
for a negotiated time period, generally overnight, of Federal funds by one Fed
Bank to another. Since, pursuant to an exemption from the reserve requirements
imposed upon depository institutions by the Board of Governors of the Federal
Reserve System (the "FRB"), the borrowing Fed Bank is not required to maintain
reserves on the borrowed Federal funds, the interest rate it pays on such
borrowings is generally higher than the rate it pays on other deposits of
comparable size and maturity that are subject to reserve requirements. In
addition, a "depository institution" or other exempt institution such as the
Trust may, under Regulation D of the FRB, in effect, make loans of Federal funds
by instructing a correspondent or other willing Fed Bank at which it maintains
an account to loan Federal funds on its behalf. Loans of Federal funds are not
federally insured.
 
The Fund may make unsecured loans of Federal funds to United States banks
provided that: 1) the accounts of such banks are federally insured; 2) the
interest received is at the market rate for Federal funds transactions; and 3)
the transaction has a specified maturity of one or more business days or the
Fund is able to require repayment at any time.
 
In the event the borrower of Federal funds enters into a bankruptcy or other
insolvency proceeding, the Fund could experience delays and incur expenses in
recovering cash. Further, the possibility exists that in such an instance, the
borrowing institution may not be able to repay the borrowed funds.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits of highly-rated
U.S. banks and U.S. branches of foreign banks; (ii) U.S. Treasury obligations
and obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued by U.S. and foreign corporations; (iv) debt
obligations with a maturity of one year or less issued by corporations that
issue high-quality commercial paper; and (v) repurchase agreements involving any
of the foregoing obligations entered into with highly-rated banks and
broker-dealers.
 
MORTGAGE-BACKED SECURITIES--Mortgage-backed securities are generally issued or
guaranteed by U.S. Government agencies, such as GNMA, FNMA, or FHLMC. GNMA
mortgaged-backed certificates are mortgage-backed securities of the modified
pass-through type, which means that both interest and principal payments
(including prepayments) are passed through monthly to the holder of the
certificate. Each GNMA certificate evidences an interest in a specific pool of
mortgage loans insured by the Federal Housing Administration or the Farmers Home
Administration or guaranteed by the Veterans Administration. FNMA, a federally
<PAGE>   247
 
 18
 
chartered and stockholder-owned corporation, issues pass-through certificates
which are guaranteed as to payment of principal and interest by FNMA. FHLMC, a
corporate instrumentality of the United States, issues participation
certificates which represent an interest in mortgages held in FHLMC's portfolio.
FHLMC guarantees the timely payment of interest and the ultimate collection of
principal. Securities issued or guaranteed by FNMA and FHLMC are not backed by
the full faith and credit of the United States.
 
There can be no assurance that the United States Government would provide
financial support to FNMA or FHLMC if necessary in the future.
 
Adjustable rate mortgage securities ("ARMs") are pass-through certificates
representing ownership interests in a pool of adjustable rate mortgages and the
resulting cash flow from those mortgages. Unlike conventional debt securities,
which provide for periodic (usually semi-annually) payments of interest and
payments of principal at maturity or on specified call dates, ARMs provide for
monthly payments based on a pro rata share of both periodic interest and
principal payments and prepayments of principal on the underlying mortgage pool
(less GNMA's, FNMA's, or FHLMC's fees and any applicable loan servicing fees).
 
Collateralized mortgage obligations ("CMOs") are bonds generally issued by
single purpose, stand-alone finance subsidiaries or trusts established by
financial institutions, government agencies, investment banks, or other similar
institutions, and collateralized by pools of mortgage loans. Payments of
principal and interest on the collateral mortgages are used to pay debt service
on the CMO. In a CMO, a series of bonds or certificates is issued in multiple
classes. Each class of CMOs, often referred to as a "tranche," is issued at a
specific coupon rate and has a stated maturity or final distribution date. The
principal and interest payment on the underlying mortgages may be allocated
among the classes of CMOs in several ways. Typically, payments of principal,
including any prepayments, on the underlying mortgages would be applied to the
classes in the order of their respective stated maturities or final distribution
dates, so that no payment of principal will be made on CMOs of a class until all
CMOs of other classes having earlier stated maturities or final distribution
dates have been paid in full.
 
One or more classes of CMOs may have coupon rates that reset periodically based
on an index, such as the London Interbank Offered Rate ("LIBOR"). The Fund may
purchase fixed, adjustable, or "floating" rate CMOs that are collateralized by
fixed rate or adjustable rate mortgages that are guaranteed as to payment of
principal and interest by an agency or instrumentality of the United States
Government, are directly guaranteed as to payment of principal and interest by
the issuer, which guarantee is collateralized by United States Government
securities, or are collateralized by privately issued fixed rate or adjustable
rate mortgages.
 
Real Estate Mortgage Investment Conduits ("REMICs") are private entities formed
for the purpose of holding a fixed pool of mortgages secured by an interest in
real property. REMICs are similar to CMOs in that they issue multiple classes of
securities.
 
REPURCHASE AGREEMENTS--Agreements by which a Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement.
The Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its right to
dispose of the collateral securities or if the Fund realizes a loss on the sale
of the collateral. A Fund will enter into repurchase agreements only with
financial institutions deemed to present minimal risk of bankruptcy during the
term of the agreement based on established guidelines. Repurchase agreements are
considered loans under the 1940 Act.
<PAGE>   248

RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
SECURITIES LENDING--In order to generate additional income, the Fund may lend
the securities in which it is invested, pursuant to agreements requiring that
the loan be continuously secured by cash, securities of the U.S. Government or
its agencies or any combination of cash and such securities as collateral equal
to 100% of the market value at all times of the loaned securities. The lending
Fund will continue to receive interest on the loaned securities while
simultaneously earning interest on the investment of cash collateral. Collateral
is marked to market daily to provide a level of collateral at least equal to the
value of the loaned securities. There may be risks of delay in receiving
additional collateral or risks of delay in recovery of the securities or even
loss of rights in the collateral should the borrower of the securities fail
financially.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United States (e.g., GNMA securities) or supported by the issuing
agencies' right to borrow from the Treasury. The issues of other agencies are
supported only by the credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the Federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates of
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates.
A demand instrument with a demand notice period exceeding seven days may be
considered illiquid
if there is no secondary market for such
security.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement

on a future date. The interest rate realized on these securities is fixed as of
the purchase date, and no interest accrued to the Fund before settlement. These
securities are subject to market fluctuation due to changes, real or
anticipated, in market interest rates, and the public's perception of the
creditworthiness of the issuer and will have the effect of leveraging the Fund's
assets. The Fund will establish one or more segregated accounts with the
Custodian, and the Fund will maintain liquid, high-grade assets in an amount at
least equal in value to the Fund's commitments to purchase when-issued
securities.

                                    SUMMARY
 
STEPSTONE FUNDS (the "Trust") is a diversified, open-end management investment
company providing a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about the
Investment Class shares of the INTERNATIONAL EQUITY FUND (the "Fund"). This
summary is qualified in its entirety by reference to the more detailed
information provided elsewhere in the Prospectus and in the Statement of
Additional Information.
 
WHAT IS THE FUND'S INVESTMENT OBJECTIVE?  THE INTERNATIONAL EQUITY FUND seeks to
provide long-term capital appreciation by investing primarily in a diversified
portfolio of equity securities of non-U.S. issuers. See "Investment Objective."
 
WHAT ARE THE FUND'S PERMITTED INVESTMENTS?  The Fund invests primarily in equity
securities (common stocks, securities convertible into common stocks, preferred
stocks, warrants and rights to purchase common stock) of non-U.S. issuers. See
"Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUND?  The investment
policies of the Fund entail certain risks and considerations of which an
investor should be aware. The Fund may purchase common stocks and other equity
securities that are volatile and may fluctuate in value more than other types of
investments. In addition, the Fund will invest in securities of foreign
companies that involve special risks and considerations not typically associated
with investing in U.S. companies. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or any instrumentalities of the securities in which any Fund invests guarantees
only the payment of principal and interest on the guaranteed security, and does
not guarantee the yield or value of the security or yield or value of shares of
that Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE SUBADVISOR?  Tokyo - Mitsubishi Asset Management (U.K.), Ltd. serves
as the SubAdvisor to the Fund. See "The SubAdvisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing
agent for the Institutional and Cash Sweep Class shares of the Trust and the
Investment Class shares of the Convertible Securities, Government Securities,
Emerging Growth, Blue Chip Growth and International Equity Funds. See
"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions may be made
through the Distributor on days on which both the New York Stock Exchange and
the Federal Reserve wire system are open for business. ("Business Days"). The
minimum initial investment is $2,000 ($1,000 for IRAs). A purchase order will be
effective if the Distributor receives an order prior to 4:00 p.m., Eastern time.
Purchase orders for shares will be executed at a per share price equal to the
net asset value next determined after the purchase order is effective (plus any
applicable sales charge). Redemption orders must be placed prior to 4:00 p.m.,
Eastern time on any Business Day for the order to be effective that day. See
"Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  Substantially all of the net investment income
(exclusive of capital gains) of the Fund is periodically declared and paid as a
dividend to Shareholders of record. Any capital gain is distributed at least
annually. Distributions are paid in additional shares unless the Shareholder
elects to take the payment in cash. See "Dividends."

THE EXAMPLE IS BASED UPON THE TOTAL OPERATING EXPENSES OF THE FUND AND SHOULD
NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES
MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this table is to assist
the investor in understanding the various costs and expenses that may be
directly or indirectly borne by investors in the Investment Class shares of the
Fund. The Trust also offers Institutional Class shares of the Fund, which are
subject to the same expenses except there are no sales charges or distribution
costs. Additional information may be found under "The Administrator," "The
Advisor" and "The SubAdvisor."
 
The rules of the Securities and Exchange Commission require that the maximum
sales charge be reflected in the above table. However, certain investors may
qualify for reduced sales charges. See "Purchase and Redemption of Shares."
 
Long-term Shareholders may pay more than the equivalent of the maximum sales
charges otherwise permitted by the Rules of the National Association of
Securities Dealers ("NASD").

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified,
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Investment Class shares of the Trust's International Equity Fund (the
"Fund"). Information regarding the Trust's other funds is contained in separate
prospectuses that may be obtained from the Trust's Distributor, SEI Financial
Services Company, 680 East Swedesford Road, Wayne, Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVE
 
THE INTERNATIONAL EQUITY FUND seeks to provide long-term capital appreciation by
investing primarily in a diversified portfolio of equity securities of non-U.S.
issuers.
 
There can be no assurance that the Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
Under normal market circumstances, at least 65% of the Fund's assets will be
invested in the following equity securities of non-U.S. issuers: common stocks,
securities convertible into common stocks, preferred stocks, warrants and rights
to purchase common stock. Under normal market conditions, at least 65% of the
Fund's total assets will be invested in securities of issuers organized under
the laws of at least five countries other than the United States that are
included in the Morgan Stanley Capital International Europe, Australia and Far
East Index (the "EAFE Index").1
 
Countries may be over- or under-weighted in comparison to the EAFE Index based
upon the Advisor's and SubAdvisor's view of forecasted rates of returns.
 
Regional and individual country weightings therefore may vary from the EAFE
Index benchmark. The Advisor and SubAdvisor will select individual securities
for the Fund on the basis of their undervaluation in relation to other
securities. The Fund expects its investments to emphasize companies with market
capitalization in excess of $100,000,000.
 
The Fund will typically invest in equity securities listed on recognized foreign
exchanges, but may also invest up to 15% of its total assets in securities
traded in over-the-counter markets. Equity securities of non-U.S. issuers may
also be purchased in the form of sponsored or unsponsored American Depositary
Receipts ("ADRs") and sponsored or unsponsored European Depositary Receipts
("EDRs").
 
The Fund may enter into forward foreign currency contracts as a hedge against
possible variations in foreign exchange rates. A forward foreign currency
contract is a commitment to purchase or sell a specified currency, at a
specified date, at a specified price. The Fund may enter into forward foreign
currency contracts to hedge a specific security transaction or to hedge a
portfolio position. These contracts may be bought and sold to protect the Fund
to some degree, against a possible loss resulting from an adverse change in the
relationship between foreign currencies. The Fund may also invest in options on
currencies.
 
The Fund may invest in futures and options on futures for the purpose of
achieving the Fund's objectives. The Fund may invest in futures and

related options based on any type of security or index traded on U.S. or foreign
exchanges or over the counter, as long as the underlying security or securities
represented by an index, are permitted investments of the Fund. Such futures
contracts may include index contracts and contracts for foreign currencies. The
Fund may enter into futures contracts and options on futures only to the extent
that obligations under such contracts or transactions, together with options on
securities or indices represent not more than 25% of the Fund's assets.
 
The premium paid of options on securities positions will not exceed 10% of the
Fund's net assets at the time such options are entered into by the Fund. The
aggregate premium paid on all options on stock indices will not exceed 20% of a
Fund's total assets.
 
The Fund's remaining assets may be invested in investment grade bonds and
debentures issued by non-U.S. or U.S. companies, obligations of supranational
entities, securities issued or guaranteed by foreign and U.S. governments, and
foreign and U.S. commercial paper. Certain of these instruments may have
floating or variable interest rate provisions. In addition, the Fund may invest
in securities of issuers whose principal activities are in countries with
emerging markets. The Fund defines an emerging market country as any country
whose economy and market the World Bank or the United Nations considers to be
emerging or developing. The Fund may also purchase shares of closed-end
investment companies that invest in the securities of issuers in a single
country or region and shares of open-end management investment companies.
 
For temporary defensive purposes during periods when the Advisor and SubAdvisor
determine that market conditions warrant, the Fund may invest up to 100% of its
assets in money market instruments and in cash. The Fund will not be pursuing
its investment objective to the extent that a substantial portion of its assets
are invested in money market securities.
 
The Fund will restrict its investment in illiquid securities to 15% of its net
assets.
 
The Fund may engage in securities lending and will limit such practice to
33 1/3% of its assets.
 
The Fund may purchase securities, which have not been registered under the
Securities Act of 1933 (Rule 144A Securities).
 
For further information see "Description of Permitted Investments."
 
RISK FACTORS
 
Since the Fund invests in equity securities, the Fund's shares will fluctuate in
value and thus may be more suitable for long-term investors who can bear the
risk of short-term fluctuations.
 
There may be certain risks connected with investing in foreign securities,
including risks of adverse political and economic developments (including
possible governmental seizure or nationalization of assets), the possible
imposition of exchange controls or other governmental restrictions, including
less uniformity in accounting and reporting requirements, the possibility that
there will be less information on such securities and their issuers available to
the public, the difficulty of obtaining or enforcing court judgments abroad,
restrictions on foreign investments in other jurisdictions, difficulties in
effecting repatriation of capital invested abroad, and difficulties in
transaction settlements and the effect of delay on shareholder equity. Foreign
securities may be subject to foreign taxes, which reduce yield, and may be less
marketable than comparable U.S. securities. The value of the Fund's investments
denominated in foreign currencies will depend on the relative strengths of those
currencies and the U.S. dollar, and the Fund may be affected favorably or
unfavorably by changes in the exchange rates or exchange control regulations
between foreign currencies and the U.S. dollar. Changes in foreign currency
exchange rates may also affect the value of dividends and interest earned, gains
and losses realized on the sale of
<PAGE>   256
 
 6
 
securities and net investment income and gains, if any, to distributed to
shareholders by the Fund.
 
Forward foreign currency contracts do not eliminate fluctuations in the
underlying prices of securities. Rather, they simply establish a rate of
exchange which one can achieve at some future point in time. Additionally,
although such contracts tend to minimize the risk of loss due to a decline in
the value of the hedged currency at the same time, they tend to limit any
potential gain which might result should the value of such currency increase.
 
The Fund's investments in emerging markets can be considered speculative, and
therefore, may offer higher potential for gains and losses than developed
markets of the world. With respect to any emerging country, there is the greater
potential for nationalization, expropriation or confiscatory taxation, political
changes, government regulation, social instability or diplomatic developments
(including war) which could affect adversely the economies of such countries or
investments in such countries. In addition, it may be difficult to obtain and
enforce a judgment in the courts of such countries. The economies of developing
countries generally are heavily dependent upon international trade and,
accordingly, have been and may continue to be adversely affected by trade
barriers, exchange controls, managed adjustments in relative currency values and
other protectionist measures imposed or negotiated by the countries with which
they trade.
 
Securities rated BBB by Standard & Poor's Corporation ("S&P") or Baa by Moody's
Investors Service, Inc. ("Moody's") are deemed by these rating services to have
some speculative characteristics and adverse economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than is the case with higher grade bonds.
 
INVESTMENT LIMITATIONS
 
The Fund may not:
 
1. Purchase securities of any issuer (except securities issued or guaranteed by
the U.S. government or its agencies or instrumentalities and repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of the Fund would be invested in the securities of such issuer. This
restriction applies to 75% of the Fund's total assets. For purposes of this
investment limitation, each foreign governmental issuer is deemed a separate
issuer.
 
2. Purchase any securities which would cause more than 25% of the total assets
of the Fund to be invested in the securities of one or more issuers conducting
their principal business activities in the same industry, provided that this
limitation does not apply to investments in the obligations issued or guaranteed
by the U.S. Government or its agencies or instrumentalities and repurchase
agreements involving such securities, and provided further, that utilities as a
group will not be considered to be one industry, and wholly-owned subsidiaries
organized to finance the operations of their parent companies will be considered
to be in the same industries as their parent companies.
 
3. Make loans, except that the Fund may (a) purchase or hold debt instruments in
accordance with its investment objective and policies; (b) enter into repurchase
agreements; and (c) engage in securities lending as described in this prospectus
and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.
 
FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Fund. Fundamental policies cannot be changed with
respect to the Fund without the consent of a majority of the Fund's outstanding
shares.

THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor continuously
reviews, supervises and administers the Fund's investment program. The Advisor
discharges its responsibilities subject to the supervision of, and policies
established by, the Trustees of the Trust. The Trust's shares are not sponsored,
endorsed or guaranteed by, and do not constitute obligations or deposits of, the
Advisor and are not guaranteed by the FDIC or any other governmental agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .95% of the average daily net assets of the Fund. Although the
advisory fee for the Fund is higher than advisory fees paid by other mutual
funds, the Trust believes that the fee is comparable to the advisory fee paid by
many other mutual funds with similar investment objectives and policies. The
Advisor may from time to time waive all or a portion of its fee in order to
limit the operating expenses of the Fund. Any such waiver is voluntary and may
be terminated at any time in the Advisor's sole discretion.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of the Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time, the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE SUBADVISOR
 
The Advisor and Tokyo-Mitsubishi Asset Management (U.K.), Ltd. (the
"SubAdvisor"), have entered into an investment subadvisory agreement relating to
the Fund (the "Investment SubAdvisory Agreement"). Under the Investment
SubAdvisory Agreement, the SubAdvisor makes the day-to-day investment decisions
for the assets of the Fund, subject to the supervision of, and policies
established by, the Advisor and the Trustees of the Trust. The Trust's shares
are not sponsored, endorsed or guaranteed by and do not constitute obligations
or deposits of the SubAdvisor and are not guaranteed by the FDIC or any other
governmental agency.

EC2 M7BT operates as a subsidiary of The Bank of Tokyo-Mitsubishi, Ltd.
Established in 1989, the SubAdvisor provides active global investment services
for segregated funds and specialist fund management.
 
Prior to February, 1995, the SubAdvisor had not previously served as the
investment advisor to mutual funds. As of April 1, 1996, Tokyo-Mitsubishi Asset
Management (U.K.), Ltd. managed assets of $2.2 billion in individual portfolios
and collective funds.
 
The SubAdvisor is entitled to a fee, which is calculated daily and paid monthly
out of the Advisor's fee, at an annual rate of .30% of the average daily net
assets of the Fund.

THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
administration agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses of the Fund's Investment Class
shares. Any such waiver is voluntary, and may be terminated at any time in the
Administrator's sole discretion.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional and Cash
Sweep Class shares of the Trust and the Investment Class shares of the
Convertible Securities, Government Securities, Emerging Growth, Blue Chip Growth
and International Equity Funds. Compensation for these services is paid under
the Administration Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement"). The Distribution Agreement is renewable annually and may be
terminated by the Distributor, by a majority vote of the Disinterested Trustees
or by a majority vote of the outstanding securities of the Trust upon not more
than 60 days written notice by either party, or upon assignment by the
Distributor.
 
The Investment Class shares have a distribution plan ("Investment Class Plan").
The Distribution Agreement and the Investment Class Plan provide that the
Investment Class shares of the Fund may bear the following distribution
expenses: (1) the cost of prospectuses, reports to Shareholders, sales
literature and other materials for potential investors; (2) advertising; and (3)
expenses incurred in connection with the promotion and sale of the Trust's
shares, including the Distributor's expenses for travel, communication, and
compensation and benefits for sales personnel. In addition, the Trust pays the
Distributor a fee of up to .40% of the Fund's Investment Class shares average
daily net assets, of which a maximum of .25% may be used to compensate
broker/dealers and service providers which provide administrative and/or
distribution services to Investment Class Shareholders or to their other
customers who beneficially own Investment Class shares.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Fund may be made on days on which
both the New York Stock Exchange and the Federal Reserve wire system are open
for business. ("Business Days"). The minimum initial investment in the Fund is
$2,000 ($1,000 for IRAs); however, the minimum investment may be waived in the
Distributor's discretion. All subsequent purchases must be at least $1,000 ($500
for IRAs).
 
Purchase orders for shares will be executed at a per share price equal to the
net asset value next determined after the receipt of the purchase order by the
Distributor (plus any applicable sales charge). The purchase price of shares of
the Fund is the net asset value next determined after a purchase order is
received and accepted by the Trust (plus a sales charge). The net asset value
per share of the Fund is determined by dividing the total market value of the
Fund's investments and other assets, less any liabilities, by the total number
of outstanding shares of the Fund. Net asset value per share is determined daily
as of
<PAGE>   259
 
 9
 
4:00 p.m., Eastern time, on any Business Day. Purchases will be made in full and
fractional shares of the Trust calculated to three decimal places. The Trust
reserves the right to reject a purchase order when the Distributor determines
that it is not in the best interest of the Trust and/or its Shareholders to
accept such order.
 
HOW TO PURCHASE THROUGH FINANCIAL INSTITUTIONS
 
Shares may be purchased through financial institutions, including the Adviser,
that provide distribution assistance or shareholder services. Shares purchased
by persons ("Customers") through financial institutions may be held of record by
the financial institution. Financial institutions may impose an earlier cut-off
time for receipt of purchase orders directed through them to allow for
processing and transmittal of these orders to the Transfer Agent for
effectiveness the same day. Customers should contact their financial institution
for information as to that institution's procedures for transmitting purchase,
exchange or redemption orders to the Trust.
 
Customers who desire to transfer the registration of shares beneficially owned
by them but held of record by a financial institution should contact the
institution to accomplish such change.
 
Depending upon the terms of a particular Customer account, a financial
institution may charge a Customer account fees. Information concerning these
services and any charges will be provided to the Customer by the financial
institution.
 
SALES CHARGES
 
Shares of the Fund are offered only to residents of states in which the shares
are eligible for purchase.
 
The following table shows the regular sales charge on Investment Class shares to
a "single purchaser" (defined below), together with the dealer discount paid to
dealers and the agency commission paid to brokers (collectively the
"commission"):

</TABLE>
 
The commissions shown in the table apply to sales through authorized dealers and
brokers. Under certain circumstances, the Distributor may use its own funds to
compensate financial institutions and intermediaries in amounts that are
additional to the commissions shown above. In addition, the Distributor may,
from time to time and at its own expense, provide promotional incentives in the
form of cash or other compensation to certain financial institutions and
intermediaries whose registered representatives have sold or are expected to
sell significant amounts of the Investment Class shares of the Fund. Such other
compensation may take the form of payments for travel expenses, including
lodging, incurred in connection with trips taken by qualifying registered
representatives to places within or without the United States. Under certain
circumstances, commissions up to the amount of the entire sales charge may be
reallowed to dealers or brokers, who might then be deemed to be "underwriters"
under the Securities Act of 1933.
 
In calculating the sales charge rates applicable to current purchases of the
Fund's shares, a "single purchaser" is entitled to cumulate current purchases
with the net purchase of previously purchased shares of the Fund and other of
the Trust's funds (the "Eligible Funds") which are sold subject to a comparable
sales charge.
 
The term "single purchaser" refers to (i) an individual, (ii) an individual and
spouse purchasing shares of the Fund for their own account or for
<PAGE>   260
 
 10
 
trust or custodial accounts for their minor children, (iii) a fiduciary
purchasing for any one trust, estate or fiduciary account including employee
benefit plans created under Sections 401, 403(b) or 457 of the Internal Revenue
Code of 1986, as amended (the "Code"), including related plans of the same
employer. To be entitled to a reduced sales charge based upon shares already
owned, the investor must ask the Distributor for such entitlement at the time of
purchase and provide the account number(s) of the investor, the investor and
spouse, and their minor children, and give the age of such children. The Fund
may amend or terminate this right of accumulation at any time as to subsequent
purchases.
 
LETTER OF INTENT.  By initially investing at least $2,000 and submitting a
Letter of Intent (the "Letter") to the Distributor, a "single purchaser" may
purchase shares of the Fund and the other Eligible Funds during a 13-month
period at the reduced sales charge rates applying to the aggregate amount of the
intended purchases stated in the Letter. The Letter may apply to purchases made
up to 90 days before the date of the Letter. To receive credit for such prior
purchases and later purchases benefitting from the Letter, the Shareholder must
notify the Transfer Agent at the time the Letter is submitted that there are
prior purchases that may apply, and, at the time of later purchases, notify the
Transfer Agent that such purchases are applicable under the Letter.
 
OTHER CIRCUMSTANCES.  No sales charge is imposed on the Investment Class shares
of the Fund: (i) issued in plans of reorganization, such as mergers, asset
acquisitions and exchange offers, to which the Trust is a party; (ii) sold to
dealers or brokers that have a sales agreement with the Distributor, for their
own account or for retirement plans for their employees or sold to employees
(and their spouses) of dealers or brokers that certify to the Distributor at the
time of purchase that such purchase is for their own account (or for the benefit
of such employees' minor children); (iii) in aggregate purchases of $1 million
or more by tax-exempt organizations enumerated in Section 501(c) of the Code, or
employee benefit plans created under Sections 401, 403(b) or 457 of the Code;
(iv) sold to employees and families of the Advisor and its affiliates; (v) sold
to fiduciary accounts of the Advisor and its affiliates; or (vi) purchased with
proceeds from the recent redemption of shares of a mutual fund with similar
investment objectives and policies for which a sales load was paid.
 
The waiver of the sales charge under clause (vi) applies only if the following
conditions are met: the purchase must be made within 60 days of the redemption;
the Distributor must be notified in writing by the investor, or his or her
agent, at the time a purchase is made; and a copy of the investor's account
statement showing such redemption must accompany such notice. The waiver policy
with respect to the purchase of shares through the use of proceeds from a recent
redemption above will not continue indefinitely and may be discontinued at any
time without notice. Investors should contact the Distributor to confirm
continued availability prior to initiating the procedures described in clause
(vi).
 
Shareholders who desire to redeem shares of the Trust must place their
redemption orders prior to 4:00 p.m., Eastern time, on any Business Day for the
order to be accepted on that Business Day. The redemption price is the net asset
value of the Fund next determined after receipt by the Distributor of the
redemption order. Payment on redemption will be made as promptly as possible
and, in any event, within seven calendar days after the redemption order is
received.
 
Payment to shareholders for shares redeemed will be made within seven days after
the Transfer Agent receives the valid redemption request. At various times,
however, a Fund may be requested to redeem shares for which it has not yet
received good payment; collection of payment may take ten or more days. In such
circumstances, the redemption request will be rejected by the Fund. Once a Fund
has received good payment for the
<PAGE>   261
 
 11
 
shares a shareholder may submit another request for redemption.
 
Due to the relatively high costs of handling small investments, each Fund
reserves the right to redeem your shares at net asset value, if, your account in
any Fund has a value of less than the minimum initial purchase amount.
Accordingly, if you purchase shares of any Fund in only the minimum investment
amount, you may be subject to involuntary redemption if you redeem any shares.
Before any Fund exercises its right to redeem such shares you will be given
notice that the value of the shares in your account is less than the minimum
amount and will be allowed 60 days to make an additional investment in such Fund
in an amount which will increase the value of the account to at least the
minimum amount.
 
Neither the Transfer Agent nor the Trust will be responsible for any loss,
liability, cost or expense for acting upon wire or telephone instructions that
it reasonably believes to be genuine. The Trust and Transfer Agent will each
employ reasonable procedures to confirm that instructions, communicated by
telephone are genuine. Such procedures may include taping of telephone
conversations.
 
If market conditions are extraordinarily active or other extraordinary
circumstance exist, and you experience difficulties placing redemption orders by
telephone, you may consider placing your order by mail.
 
PURCHASES BY EXCHANGE
 
As permitted pursuant to any rule, regulation or order promulgated by the
Securities and Exchange Commission, shareholders of Investment Class shares of
other funds of the Trust that have similar sales charges may tender their shares
of those Funds for exchange into the number of shares (including fractional
shares) which have a value equal to the total net asset value of shares tendered
divided by the net asset value of Investment Class shares of the Fund next
determined after such order is received. Shares issued pursuant to this offer
will not be subject to the sales charge described above or any other charge. The
Fund may modify or terminate this exchange offer at any time upon 60 days'
notice.
 
PERFORMANCE
 
From time to time, the Fund may advertise yield and total return. These figures
will be based on historical earnings and are not intended to indicate future
performance. The yield of the Fund refers to the annualized income generated by
an investment in the Fund over a specified 30-day period. The yield is
calculated by assuming that the same amount of income generated by the
investment during that period is generated in each 30-day period over one year
and is shown as a percentage of the investment.
 
The total return of the Fund refers to the average compounded rate of return to
a hypothetical investment, for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period and assuming the reinvestment of all dividend and capital gain
distributions. The total return of the Fund may also be quoted as a dollar
amount or on an aggregate basis, an actual basis, without inclusion of any sales
charge, or with a reduced sales charge in advertisements distributed to
investors entitled to a reduced sales charge.
 
The Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Fund may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Fund may use long term performance of these
capital markets to demonstrate general
<PAGE>   262
 
 12
 
long-term risk versus reward scenarios and could include the value of a
hypothetical investment in any of the capital markets. The Fund may also quote
financial and business publications and periodicals as they relate to fund
management, investment philosophy, and investment techniques.
 
The Fund may quote various measures of volatility and benchmark correlation in
advertising, and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class shares because the Institutional Class is not subject to
distribution expenses generally charged to the Investment Class shares.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to provide a detailed
explanation of the federal, state, or local income tax treatment of the Fund or
its Shareholders. In addition, state and local tax consequences of an investment
in the Fund may differ from the federal income tax consequences described below.
Accordingly, Shareholders are urged to consult their tax advisers regarding
specific questions as to federal, state and local income taxes. Additional
information concerning taxes is set forth in the Statement of Additional
Information.
 
TAX STATUS OF THE FUND:
 
The Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. The Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so that it will be relieved of
federal income tax on that part of its net investment company taxable income and
net capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
The Fund will distribute substantially all of its net investment income
(including net short-term capital gain) and net capital gain to Shareholders.
Dividends from the Fund's net investment company taxable income are taxable to
Shareholders as ordinary income, (whether received in cash or in additional
shares) to the extent of the Fund's earnings and profits. Distributions of net
capital gain are taxable to Shareholders as long-term capital gain, regardless
of how long Shareholders have held their shares and regardless of whether the
distributions are received in cash or in additional shares. Dividends and
distributions of capital gain paid by the Fund do not qualify for the dividends
received deduction for corporate shareholders. The Fund will provide annual
reports to Shareholders of the federal income tax status of all distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS, which are sold at
original issue discount and thus do not make periodic cash interest payments,
the Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because the Fund distributes
all of its net investment income to its shareholders, the Fund may have to sell
portfolio securities to distribute such imputed income, which may occur at a
time when the Advisor or SubAdvisor would not have chosen to sell such
securities and which may result in a taxable gain or loss.
 
Income derived by the Fund from obligations of foreign issuers may be subject to
foreign withholding taxes. The Fund expects to elect to
<PAGE>   263
 
 13
 
treat Shareholders as having paid their proportionate share of such taxes.
 
Investment income received directly by the Fund on direct U.S. obligations is
exempt from tax at the state level and may be exempt, depending on the state,
when received by a Shareholder as income dividends from the Fund, provided
certain state-specific conditions are satisfied. Interest realized on repurchase
agreements collateralized by U.S. government obligations normally is not exempt
from state tax. The Fund will inform Shareholders annually of the percentage of
income and distributions derived from direct U.S. Treasury obligations.
Shareholders should consult their tax advisors to determine whether any portion
of the income dividends received from the Fund is considered tax exempt in their
particular state.
 
Dividends declared by the Fund in October, November, or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
The Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Each sale, exchange, or redemption of Fund Shares is a taxable transaction to
the Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate portfolios of shares and different classes of each fund. In
addition to the Fund, the Trust consists of the following funds: Treasury Money
Market Fund, Money Market Fund, California Tax-Free Money Market Fund,
Intermediate-Term Bond Fund, California Intermediate Tax-Free Bond Fund, Limited
Maturity Government Fund, Blue Chip Growth Fund, Convertible Securities Fund,
Government Securities Fund, Balanced Fund, Value Momentum Fund, Growth Equity
Fund, and Emerging Growth Fund. All consideration received by the Trust for
shares of any fund and all assets of such fund belong to that fund, and would be
subject to liabilities related thereto. The Trust reserves the right to create
and issue shares of additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses. Please refer to "Financial Highlights" in this Prospectus
for more information regarding the Trust's expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings, but approval will be sought for certain changes in the
operation of the Trust and for the election of Trustees under certain
circumstances. In addition, a Trustee may be removed by the remaining Trustees
or by Shareholders at a special meeting called upon the written request of
Shareholders owning at least 10% of the outstanding shares of the Trust. In the
event that such a meeting is requested the Trust will provide
<PAGE>   264
 
 14
 
appropriate assistance and information to the Shareholders requesting the
information.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658.
 
DIVIDENDS
 
Substantially all of the net investment income (exclusive of capital gains) of
the Fund is periodically declared and paid as a dividend to Shareholders of
record. Currently, capital gains of the Fund, if any, will be distributed at
least annually.
 
Shareholders automatically receive all income dividends and capital gain
distributions in additional shares at the net asset value next determined
following the record date, unless the Shareholder has elected to take such
payment in cash. Shareholders may change their election by providing written
notice to the Administrator at least 15 days prior to the change.
 
Dividends and distributions of the Fund are paid on a per-share basis. The value
of each share will be reduced by the amount of the payment. If shares are
purchased shortly before the record date for a dividend or the distribution of
capital gains, a Shareholder will pay the full price for the shares and receive
some portion of the price back as a taxable dividend or distribution.
 
The dividends payable on Investment Class shares will typically be lower than
dividends payable on Institutional Class shares because of the distribution
expenses charged to Investment Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
State Street Bank and Trust Company, 225 Franklin Street, Boston, Massachusetts
02110 (the "Custodian"), acts as Custodian of the assets of the Fund. The
Custodian holds cash, securities and other assets of the Trust as required by
the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Fund:
 
AMERICAN DEPOSITARY RECEIPTS ("ADRs") and EUROPEAN DEPOSITARY RECEIPTS
("EDRs")--Receipts, typically issued by a U.S. financial institution (a
"depositary"), that evidence ownership interests in a security or a pool of
securities issued by a foreign issuer and deposited with the depositary. ADRs
include American Depositary Shares and New York Shares. EDRs, which are
sometimes referred to as Continental Depositary Receipts ("CDRs"), are
securities, typically issued by a non-U.S. financial institution, that evidence
ownership interests in a security or a pool of securities issued by either a
U.S. or foreign issuer. ADRs, EDRs and CDRs may be available for investment
through "sponsored" or "unsponsored" facilities. A sponsored facility is
established jointly by the issuer of the security underlying the receipt and a
depositary, whereas an unsponsored facility may be established by a depositary
without participation by the issuer of the receipt's underlying security.
 
Holders of an unsponsored depositary receipt generally bear all the costs of the
unsponsored facility. The depositary of an unsponsored facility frequently is
under no obligation to distribute shareholder communications received from the
issuer of the deposited security or to pass through to the holders of the
receipts voting rights with respect to the deposited securities.
<PAGE>   265

CONVERTIBLE PREFERRED STOCK--Convertible preferred stock is a class of capital
stock that pays dividends at a specified rate and has preference over common
stock in the payment of dividends and the liquidation of assets. Convertible
preferred stock is preferred stock exchangeable for a given number of common
stock shares and has characteristics similar to both fixed-income and equity
securities. Because of the conversion feature, the market value of convertible
preferred stock tends to move together with the market value of the underlying
common stock. As a result, the Fund's selection of convertible preferred stock
is based, to a great extent, on the potential for capital appreciation that may
exist in the underlying common stock. The value of convertible preferred stock
is also affected by prevailing interest rates, the credit quality of the issuer,
and any call provisions.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
FORWARD FOREIGN CURRENCY CONTRACTS-- The Fund may conduct its foreign currency
exchange transactions on a spot (i.e., cash) basis at the spot rate prevailing
in the foreign currency exchange market or through entering into forward
currency contracts to protect against uncertainty in the level of future
exchange rates between particular currencies or between foreign currencies in
which the Fund's securities are or may be denominated. A forward contract
involves an obligation to purchase or sell a specific currency amount at a
future date, which may be any fixed number of days from the date of the
contract, agreed upon by the parties, at a price set at the time of the
contract. Under normal circumstances, consideration of the prospect for changes
in currency exchange rates will be incorporated into the Fund's long-term
investment strategies. However, the Advisor and SubAdvisor believe that it is
important to have the flexibility to enter into forward currency contracts when
it determines that the best interests of the Fund will be served.
 
When the Advisor and SubAdvisor believe that the currency of a particular
country may suffer a significant decline against another currency, the Fund may
enter into a currency contract to sell, for the appropriate currency, the amount
of foreign currency approximating the value of some or all of the Fund's
securities denominated in such foreign currency.
 
At the maturity of a forward contract, the Fund may either sell a fund security
and make delivery of the foreign currency, or it may retain the security and
terminate its contractual obligation to deliver the foreign currency by
purchasing an "offsetting" contract with the same currency trader, obligating it
to purchase on the same maturity date, the same amount of the foreign currency.
The Fund may realize a gain or loss from currency transactions.
 
FUTURES AND OPTIONS ON FUTURES--Some futures strategies, including selling
futures, buying puts and writing calls, reduce the Fund's exposure to price
fluctuations. Other strategies, including buying futures, writing puts and
buying calls, tend to increase market exposure. Futures and options may be
combined with each other in order to adjust the risk and return characteristics
of the overall portfolio.
 
Options and futures can be volatile instruments, and involve certain risks that
if applied at an inappropriate time, could negatively impact a Fund's return.
 
MONEY MARKET INSTRUMENTS--Money market securities are high-quality,
dollar-denominated, short-term debt instruments. They consist of: (i) bankers'
acceptances, certificates of deposits, notes and time deposits issued by
highly-rated U.S. banks and U.S. branches of foreign banks having net assets of
at least $1 billion as of the
<PAGE>   266
 
 16
 
end of their most recent fiscal year; (ii) U.S. Treasury obligations and
obligations of agencies and instrumentalities of the U.S. Government; (iii)
high-quality commercial paper issued (i.e., rated A-1 by S&P or P-1 by Moody's)
by U.S. and foreign corporations; (iv) debt obligations with a maturity of one
year or less issued by corporations that issue high-quality commercial paper;
and (v) repurchase agreements involving any of the foregoing obligations entered
into with highly-rated banks and broker-dealers.
 
OBLIGATIONS OF SUPRANATIONAL ENTITIES-- Obligations of supranational entities
are established through the joint participation of several governments, and
include the Asian Development Bank, the Inter-American Development Bank,
International Bank for Reconstruction and Development (World Bank), African
Development Bank, European Economic Community, European Investment Bank and the
Nordic Investment Bank.
 
OPTIONS--Under a call option, the purchaser of the option has the right to
purchase, and the writer (the Fund) the obligation to sell, the underlying
security at the exercise price during the option period. A put option gives the
purchaser the right to sell, and the writer the obligation to purchase, the
underlying security at the exercise price during the option period.
 
In addition, the Fund may buy options on stock indices to invest cash on an
interim basis. Such options will be listed on a U.S. or foreign securities
exchange. In order to close out an option position, the Fund may enter into a
"closing purchase transaction"--the purchase of an option on the same security
with the same exercise price and expiration date as the option contract
previously written on any particular security. When the security is sold, the
Fund effects a closing purchase transaction so as to close out any existing
option on that security.
 
There are risks associated with such investments including the following: (1)
the success of a hedging strategy may depend on the ability of the Advisor or
SubAdvisor to predict movements in the prices of individual securities,
fluctuations in markets and movements in interest rates; (2) there may be an
imperfect correlation between the movement in prices of securities held by a
Fund and the price of options; (3) there may not be a liquid secondary market
for options; and (4) while a Fund will receive a premium when it writes covered
call options, it may not participate fully in a rise in the market value of the
underlying security.
 
OPTIONS ON CURRENCIES--The Fund may purchase options and write covered call
options on foreign currencies (traded on U.S. and foreign exchanges or
over-the-counter markets) to manage the Fund's exposure to changes in dollar
exchange rates. Call options on foreign currency written by the Fund will be
"covered," which means that the Fund will own an equal amount of the underlying
foreign currency. With respect to put options on foreign currency written by the
Fund, the Fund will establish a segregated account with its Custodian consisting
of cash, U.S. government securities or other liquid high grade debt securities
in an amount equal to the amount the Fund would be required to pay upon exercise
of the put.
 
REPURCHASE AGREEMENTS--Agreements by which the Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. The Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement.
The Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from its rights to dispose of
the collateral securities or if the Fund realizes a loss in the sale of the
collateral. The Fund will enter into repurchase agreements only with financial
institutions deemed to present minimal risk of bankruptcy during the term of the
agreement based on established guidelines. Repurchase agreements are considered
loans under the 1940 Act.
<PAGE>   267
 
 17
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933, but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
SECURITIES LENDING--In order to generate additional income, the Fund may lend
the securities in which it is invested, in order to generate additional income,
pursuant to agreements requiring that the loan be continuously secured by cash,
securities of the U.S. Government or its agencies or any combination of cash and
such securities as collateral equal to 100% of the market value at all times of
the loaned securities. The lending Fund will continue to receive interest on the
loaned securities while simultaneously earning interest on the investment of
cash collateral. Collateral is marked to market daily to provide a level of
collateral at least equal to the value of the loaned securities. There may be
risks of delay in receiving additional collateral or risks of delay in recovery
of the securities or even loss of rights in the collateral should the borrower
of the securities fail financially.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. government, are either backed by the full faith and
credit of the United States or supported by the issuing agencies' right to
borrow from the Treasury.
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks and brokerage firms and
are created by depositing Treasury notes and Treasury bonds into a special
account at a custodian bank. The custodian holds the interest and principal
payments for the benefit of the registered owners of the certificates or
receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
"Treasury Receipts" ("TR's") "Treasury Investment Growth Receipts" ("TIGR's")
and "Certificates of Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and
CATS are sold as zero coupon securities, which means that they are sold at a
substantial discount and redeemed at face value at their maturity date without
interim cash payments of interest or principal. This discount is accreted over
the life of the security, and such accretion will constitute the income earned
on the security for both accounting and tax purposes. Because of these features,
such securities may be subject to greater interest rate volatility than interest
paying securities. See also "Taxes".
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve a conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.
 
WARRANTS--Securities that entitle the holder to buy a proportionate amount of
common stock at a specified price for a limited or unlimited period of time.
Warrants are often freely transferable and are traded on major stock exchanges.

STEPSTONE FUNDS (the "Trust") is a diversified open-end management investment
company which provides a convenient way to invest in professionally managed
portfolios of securities. The following provides basic information about Cash
Sweep Class shares of the MONEY MARKET and TREASURY MONEY MARKET FUNDS (each a
"Fund"). This summary is qualified in its entirety by reference to the more
detailed information provided elsewhere in this Prospectus and in the Statement
of Additional Information.
 
WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?  THE MONEY MARKET FUND seeks to
preserve principal value and maintain a high degree of liquidity while providing
current income. THE TREASURY MONEY MARKET FUND seeks to preserve principal value
and maintain a high degree of liquidity while providing current income. See
"Investment Objectives."
 
WHAT ARE THE FUNDS' PERMITTED INVESTMENTS?  THE MONEY MARKET FUND invests in
obligations denominated in U.S. dollars, including commercial paper, bank
obligations, thrift and savings and loan obligations, short-term corporate
obligations, general U.S. Government obligations and repurchase agreements
involving such obligations, receipts evidencing ownership of component parts of
U.S. Treasury obligations and securities issued or guaranteed by foreign
branches of foreign banks and foreign commercial paper. THE TREASURY MONEY
MARKET FUND invests exclusively in direct obligations issued by the U.S.
Treasury, separately traded component parts of such obligations transferable
through the Federal book-entry system, and repurchase agreements involving such
obligations. See "Investment Policies."
 
WHAT ARE THE RISKS INVOLVED WITH AN INVESTMENT IN THE FUNDS?  Each Fund seeks to
maintain a net asset value of $1.00 per share. There can be no assurance that a
Fund will be able to maintain a net asset value of $1.00 per share on a
continuous basis. See "Risk Factors."
 
ARE MY INVESTMENTS INSURED?  Any guarantee by the U.S. Government, its agencies
or instrumentalities of the securities in which any Fund invests guarantees only
the payment of principal and interest on the guaranteed security and does not
guarantee the yield or value of the security or yield or value of shares of that
Fund. The Trust's shares are not federally insured by the FDIC or any other
government agency.
 
WHO IS THE ADVISOR?  MERUS-UCA Capital Management, a division of Union Bank of
California, N.A., serves as the Advisor to the Trust. See "The Advisor."
 
WHO IS THE ADMINISTRATOR?  SEI Financial Management Corporation serves as the
Administrator of the Trust. See "The Administrator."
 
WHO IS THE SHAREHOLDER SERVICING AGENT?  SEI Financial Management Corporation
serves as transfer agent, dividend disbursing agent, and shareholder servicing

"Shareholder Servicing Agent."
 
WHO IS THE DISTRIBUTOR?  SEI Financial Services Company acts as Distributor of
the Trust's shares. See "The Distributor."
 
HOW DO I PURCHASE AND REDEEM SHARES?  Purchases and redemptions will be effected
pursuant to the terms and conditions of Cash Sweep accounts entered into by
shareholders with Union Bank and its affiliates and correspondents. Orders may
be placed on days on which both the New York Stock Exchange and the Federal
Reserve wire system are open for business ("Business Days"). The minimum initial
investment is $1,000. Shareholders must place orders to purchase prior to 9:00
a.m. Pacific time or orders to redeem prior to 9:00 a.m. Pacific time for the
Money Market and Treasury Money Market Fund on any Business Day. Otherwise the
order will be effective the next Business Day. In addition, effectiveness of a
purchase is contingent on the Custodian's receipt of Federal funds before 11:00
a.m. Pacific time. See "Purchase and Redemption of Shares."
 
HOW ARE DIVIDENDS PAID?  The net investment income (exclusive of short-term
capital gains) of the Funds is determined and declared on each Business Day as a

(1) The Advisor has voluntarily agreed to waive fees to the extent necessary in
    order to limit Total Operating Expenses of the Treasury Money Market Fund.
    The Advisor reserves the right to terminate its waiver at any time in its
    sole discretion. Absent this fee waiver, the Advisory Fees would be .30% for
    the Fund.
(2) The Cash Sweep Class Plan provides that the Cash Sweep Class shares will
    bear the costs of distribution expenses and, in addition, the Trust may pay
    the Distributor a fee of up to .50% of the Cash Sweep Class shares' average
    daily net assets, which may be used to compensate broker/dealers and service
    providers. See "The Distributor" for further information. The Distributor
    has agreed to waive fees so that such fees payable under the Cash Sweep Plan
    are limited to .35%.
(3) Absent fee waivers, "Total Operating Expenses" would be 1.00% and 1.00% for
    the Money Market Fund and Treasury Money Market Fund, respectively.

THE TRUST
 
STEPSTONE FUNDS (formerly Union Investors Funds) (the "Trust") is a diversified
open-end management investment company that offers units of beneficial interest
("shares") in fourteen separate funds. Shareholders may purchase shares of
twelve of the funds through two separate classes of shares (Institutional and
Investment Classes) and through three separate classes of the Money Market and
Treasury Money Market Funds (Institutional, Investment and Cash Sweep Classes),
which provide for variations in distribution costs, voting rights and dividends.
Except for these differences among the classes, each share of each fund
represents an equal proportionate interest in that fund. This Prospectus relates
to the Cash Sweep Class shares of the Trust's Money Market and Treasury Money
Market Funds (each a "Fund"). Information regarding the Trust's other funds is
contained in separate prospectuses that may be obtained from the Trust's
Distributor, SEI Financial Services Company, 680 East Swedesford Road, Wayne,
Pennsylvania 19087-1658.
 
INVESTMENT OBJECTIVES
 
THE MONEY MARKET FUND seeks to preserve principal value and maintain a high
degree of liquidity while providing current income.
 
THE TREASURY MONEY MARKET FUND seeks to preserve principal value and maintain a
high degree of liquidity while providing current income.
 
There can be no assurance that a Fund's investment objective will be met.
 
INVESTMENT POLICIES
 
MONEY MARKET FUND
 
The Money Market Fund invests in obligations denominated in U.S. dollars
consisting of: (i) commercial paper (including Section 4(2) Commercial Paper)
issued by domestic and foreign issuers rated at least A-1 by Standard & Poor's
Corporation ("S&P") or Prime-1 by Moody's Investors Service ("Moody's") at the
time of investment or, if not rated, as determined by the Advisor to be of
comparable quality; (ii) obligations (certificates of deposit, bank notes, time
deposits, and bankers' acceptances) of thrift institutions, savings and loans,
U.S. commercial banks (including foreign branches of such banks), and U.S. and
foreign branches of foreign banks, provided that such institutions (or, in the
case of a branch, the parent institution) have total assets of $1 billion or
more as shown on their last published financial statements at the time of
investment; (iii) short-term corporate obligations (including Rule 144A
Securities) with a remaining term of not more than 397 days of issuers with
commercial paper of comparable priority and security meeting the above ratings
criteria or determined by the Advisor to be of comparable quality; (iv) general
obligations issued by the U.S. Government and backed by its full faith and
credit, and obligations issued or guaranteed as to principal and interest by the
agencies or instrumentalities of the U.S. Government (e.g., obligations issued
by Farmers Home Administration, Government National Mortgage Association,
Federal Farm Credit Bank and Federal Housing Administration); (v) receipts,
including TR's, TIGR's and CATS; (vi) repurchase agreements involving such
obligations; (vii) loan participations; (viii) readily-marketable securities
backed by company receivables, truck and auto loans, leases, and credit card
loans provided that such instruments satisfy the rating requirements described
above or are determined by the Advisor to be of comparable quality and (ix) U.S.
dollar denominated securities issued or guaranteed by foreign governments, their
political subdivisions, agencies or instrumentalities, and obligations of
supranational entities such as the World Bank and the Asian Development Bank;
provided that the Fund invests no more than 5% of its assets in any such
instrument and invests no more than 25% of its assets in such instruments in the
aggregate. The Advisor will determine that the permitted investments present
minimal credit risks in accordance with guidelines established by the Trust's
Board of Trustees.
 
The Fund may concentrate its investments in certain instruments issued by U.S.
banks, U.S.
<PAGE>   273

branches of foreign banks and foreign branches of U.S. banks, but only so long
as the investment risk associated with investing in foreign branches of domestic
banks is the same as that associated with investing in instruments issued by the
U.S. parent, in that the U.S. parent would be unconditionally liable in the
event that the foreign branch failed to pay.
 
The Fund may invest up to 5% of its total assets in loan participations issued
by a bank in the United States with assets exceeding $1 billion where the
underlying loan is made to a borrower in whose obligations the Fund may invest
and the underlying loan has a remaining maturity of one year or less.
 
TREASURY MONEY MARKET FUND
 
The Treasury Money Market Fund invests exclusively in direct obligations issued
by the U.S. Treasury, separately traded component parts of such obligations
transferable through the Federal book-entry system ("STRIPS"), and repurchase
agreements involving such obligations.
 
The Fund is limited to making investments and engaging in investment
transactions that are permissible for federal credit unions.
 
Guarantees of the Fund's portfolio securities by the U.S. Government or its
agencies or instrumentalities guarantee only the principal and interest on the
guaranteed securities, and do not guarantee the securities' yield or value or
the yield or value of the Fund's shares.
 
GENERAL INVESTMENT POLICIES
 
Each Fund intends to comply with Rule 2a-7 adopted by the Securities and
Exchange Commission ("SEC"), which Rule permits money market funds to use the
amortized cost method for calculating net asset value. The Rule imposes certain
quality, maturity and diversification restraints on investments by a Fund. Under
the Rule, a Fund will invest only in U.S. dollar denominated securities, will
maintain an average maturity on a dollar-weighted basis of 90 days or less, and
will acquire only "eligible securities" that present minimal credit risks and
have a maturity of 397 days or less. For a further discussion, see the
"Description of Permitted Investments."
 
Each Fund may enter into forward commitments, or purchase securities on a
when-issued basis. A Fund is permitted to invest in when-issued securities where
such purchases are for investment and not for leveraging purposes; however, a
Fund may sell these securities before the settlement date if it is deemed
advisable. No additional forward commitments will be made if more than 20% of a
Fund's net assets would be so committed.
 
Each Fund may engage in securities lending, and will limit such practice to
33 1/3% of its total assets.
 
Each Fund will limit its investment in illiquid securities to 10% of its net
assets.
 
For further information, see "Description of Permitted Investments."
 
ELIGIBILITY UNDER FEDERAL CREDIT
UNION ACT
 
Shares of the Treasury Money Market Fund (the Fund) are designed to qualify as
eligible investments for federally chartered credit unions pursuant to Section
107(7), 107(8) and 107(15) of the Federal Credit Union Act and Part 703 of the
National Credit Union Administration Rules and Regulations. The Fund will
continually monitor changes in the applicable laws, rules and regulations
governing eligible investments, including new investments, for federally
chartered credit unions and will take such action as may be necessary to assure
that the Fund's investments, and, therefore, shares of the Fund, continue to
qualify as eligible investments under the Federal Credit Union Act.
 
Sections 107(7), 107(8) and 107(15) of the Federal Credit Union Act set forth
those securities, deposits and other obligations in which federally chartered
credit unions may invest. The Fund's investments consist exclusively of assets
designed to qualify as eligible investments if owned directly
<PAGE>   274
 
 6
 
by a federally chartered credit union. Shares of the Fund may or may not qualify
as eligible investments for particular state chartered credit unions.
Accordingly, the Fund encourages, but does not require, each state chartered
credit union to consult qualified legal counsel concerning whether the Fund's
shares are permissible investments for that credit union. While the Advisor will
assure that the Fund follows investment policies set forth herein, the Fund
cannot be responsible for compliance by participating state chartered credit
unions with limitations on permissible investments to which they may be subject.
 
RISK FACTORS
 
It is a fundamental policy of each Fund to use its best efforts to maintain a
constant net asset value of $1.00 per share. There can be no assurance that a
Fund will be able to maintain a stable net asset value of $1.00 per share.
 
Foreign securities which the Money Market Fund may purchase involve risks that
are different from investments in securities of U.S. issuers. These risks may
include future unfavorable political and economic developments, possible
withholding taxes, seizure of foreign deposits, currency controls, interest
limitations or other government restrictions which might affect payment of
principal or interest. Additionally, there may be less public information
available about foreign issuers. Foreign branches of foreign banks are not
regulated by U.S. banking authorities, and foreign issuers generally are not
bound by accounting, auditing and financial reporting standards comparable to
U.S. issuers.
 
INVESTMENT LIMITATIONS
 
1. The Money Market Fund and the Treasury Money Market Fund may not purchase
securities of any issuer (except securities issued or guaranteed by the United
States its agencies or instrumentalities and repurchase agreements involving
such securities) if as a result more than 5% of the total assets of the Fund
would be invested in the securities of such issuer. While this restriction
applies to 75% of each Fund's assets, the Money Market Fund and the Treasury
Money Market Fund have each adopted, in accordance with Rule 2a-7, a policy
providing that the 5% limitation shall apply to 100% of the Fund's assets,
provided, however, that each Fund may invest up to 25% of its assets in the
First Tier quality securities of a single issuer for up to three days. For
purposes of this limitation, loan participations are considered to be issued by
both the issuing bank and the underlying corporate borrower.
 
2. Each Fund may not purchase any securities which would cause more than 25% of
its total assets to be invested in the securities of one or more issuers
conducting their principal business activities in the same industry, provided
that this limitation does not apply to investments in the obligations issued or
guaranteed by the U.S. Government or its agencies and instrumentalities and
repurchase agreements involving such securities, and provided further, that
utilities as a group will not be considered to be one industry, and wholly-owned
subsidiaries organized to finance the operations of their parent companies will
be considered to be in the same industry as their parent companies. For purposes
of this limitation, loan participations are considered to be issued by both the
issuing bank and the underlying corporate borrower, and supranational entities
are considered to be a separate industry. This limitation does not apply to
investments by the Money Market Fund in certain bank instruments.
 
3. Each Fund may not make loans, except that a Fund may (a) purchase or hold
debt instruments in accordance with its investment objective and policies; (b)
enter into repurchase agreements; and (c) engage in securities lending as
described in this Prospectus and in the Statement of Additional Information.
 
The foregoing percentages will apply at the time of the purchase of a security.
Additional fundamental and non-fundamental investment limitations are set forth
in the Statement of Additional Information.

FUNDAMENTAL POLICIES
 
The investment objective and certain of the investment limitations are
fundamental policies of the Funds. It is also a fundamental policy of each Fund
to use its best efforts to maintain a constant net asset value of $1.00 per
share. Fundamental policies cannot be changed with respect to a Fund without the
consent of a majority of the Fund's outstanding shares.
 
THE ADVISOR
 
The Trust and MERUS-UCA Capital Management, a division of Union Bank of
California, N.A. (the "Advisor"), have entered into an advisory agreement (the
"Advisory Agreement"). Under the Advisory Agreement, the Advisor makes the
investment decisions for the assets of each Fund and continuously reviews,
supervises and administers the Fund's investment program. The Advisor discharges
its responsibilities subject to the supervision of, and policies established by,
the Trustees of the Trust. The Trust's shares are not sponsored, endorsed or
guaranteed by, and do not constitute obligations or deposits of, the Advisor and
are not guaranteed by the FDIC or any other government agency.
 
The Advisor is entitled to a fee, which is calculated daily and paid monthly, at
an annual rate of .30% of the average daily net assets of each Fund. The Advisor
may from time to time voluntarily waive all or a portion of its fees in order to
limit the operating expenses of a Fund. Any such waiver is voluntary and may be
terminated at any time in the Advisor's sole discretion.
 
For the fiscal year ended January 31, 1996, the Money Market and Treasury Money
Market Funds paid Union Bank, predecessor of the Advisor, a fee of .30% and .25%
of their average daily net assets, respectively.
 
MERUS-UCA Capital Management (the "Advisor"), 475 Sansome Street, San Francisco,
California 94111, the investment management division of Union Bank of
California, N.A., manages the day-to-day operations of each Fund. On April 1,
1996, Union Bank, the Trust's then-investment advisor, combined with The Bank of
California, N.A., and the resulting bank changed its name to Union Bank of
California, N.A. At the same time the banks' investment management divisions
were combined. Each of Union Bank and The Bank of California, N.A. (or its
predecessor bank) has been in banking since the early 1900's, and historically,
each has had significant investment functions within its trust and investment
division. Union Bank of California, N.A., is a subsidiary of The Bank of
Tokyo-Mitsubishi, Ltd.
 
As of April 1, 1996, the Advisor managed approximately $12 billion in individual
portfolios and collective funds. The Advisor's clients range from pension funds,
national labor union plans and foundations to personal investments and trust
portfolios.
 
THE ADMINISTRATOR
 
SEI Financial Management Corporation (the "Administrator"), a wholly-owned
subsidiary of SEI Corporation ("SEI"), and the Trust are parties to an
Administration Agreement (the "Administration Agreement"). Under the terms of
the Administration Agreement, the Administrator provides the Trust with certain
management services including all necessary office space, equipment, personnel,
and facilities.
 
The Administrator is entitled to a fee, which is calculated daily and paid
monthly, at an annual rate of .15% of Trust assets up to $1 billion, .12% of
assets between $1 billion and $2 billion and .10% of assets over $2 billion. The
Administrator may waive its fee or reimburse various expenses to the extent
necessary to limit the total operating expenses applicable to a Fund's Cash
Sweep Class shares. Any such waiver is voluntary, and may be terminated at any
time.
 
THE SHAREHOLDER SERVICING AGENT
 
SEI Financial Management Corporation serves as the transfer agent, dividend
disbursing agent, and shareholder servicing agent for the Institutional and Cash
Sweep Class shares of the Trust and the Investment Class shares of the
Convertible
<PAGE>   276
 
 8
 
Securities, Government Securities, Emerging Growth, Blue Chip Growth and
International Equity Funds. Compensation for these services is paid under the
Administration Agreement.
 
DISTRIBUTION
 
SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary of
SEI, Corporation (SEI), and the Trust are parties to a distribution agreement
("Distribution Agreement"). The Distribution Agreement is renewable annually and
may be terminated by the Distributor, by a majority vote of the Disinterested
Trustees or by a majority vote of the outstanding securities of the Trust upon
not more than 60 days written notice by either party, or upon assignment by the
Distributor.
 
The Cash Sweep Class shares have a distribution plan ("Cash Sweep Class Plan").
The Cash Sweep Class Plan provides that the Cash Sweep Class shares of a Fund
will reimburse the Distributor for the following expenses: (1) the cost of
prospectuses, reports to Shareholders, sales literature and other materials for
potential investors and (2) expenses incurred in connection with the promotion
and sale of the Trust's shares including expenses for travel, communication, and
compensation and benefits for sales personnel.
 
In addition, the Trust pays the Distributor a fee of up to .50% of a Fund's Cash
Sweep Class shares average daily net assets, which can be used by the
Distributor to compensate broker/dealers and service providers. The Distributor
has agreed to waive any fees payable pursuant to the Plan other than .35%. The
Distributor reserves the right to terminate its waiver at any time in its sole
discretion.
 
PURCHASE AND REDEMPTION OF SHARES
 
Purchases and redemptions of shares of the Funds may be made on days on which
both the New York Stock Exchange and the Federal Reserve wire system are open
for business ("Business Days"). Such orders will generally be effected pursuant
to the terms and conditions of Cash Sweep accounts entered into by shareholders
of the Funds with Union Bank and its affiliates and correspondents. The minimum
initial investment is $1,000.
 
At the end of each business day a shareholder's commercial demand deposit
account at Union Bank is automatically reviewed to identify funds available for
automatic investment. Fund shares are then purchased in $1,000 increments. When
the shareholder's commercial demand deposit account falls below a predetermined
target, Fund shares are redeemed in $1,000 increments, up to the balance of the
Fund account, as needed to raise a shareholder's commercial demand deposit
account to the target balance.
 
Purchase orders will be effective on the Business Day made if the Distributor
receives an order before 12:00 noon, Eastern time on such Business Day.
Otherwise, the purchase order will be effective the next Business Day.
Effectiveness of a purchase order on any Business Day is contingent on the
Custodian's receipt of Federal funds before 2:00 p.m., Eastern time on such day.
The purchase price is the net asset value per share, which is expected to remain
constant at $1.00. The net asset value per share is calculated as of 12:00 noon,
Eastern time, each Business Day based on the amortized cost method. The net
asset value per share of a Fund is determined by dividing the total value of its
investments and other assets, less any liabilities, by the total number of its
outstanding shares. The Trust reserves the right to reject a purchase order when
the Distributor determines that it is not in the best interest of the Trust
and/or Shareholder(s).
 
Shares of the Funds are offered only to residents of states in which the shares
are eligible for purchase.
 
The Trust is required to redeem for cash all full and fractional shares of the
Trust. The redemption price is the net asset value per share of a Fund (normally
$1.00 per share).
 
Redemption orders may be made any time before 12:00 noon, Eastern time for the
Money Market and Treasury Money Market Funds in order to receive that day's
redemption price (i.e. the next
<PAGE>   277
 
 9
 
determined net asset value per share). For redemption orders received before
12:00 noon, Eastern time, payment will be made the same day by transfer of
federal funds. Otherwise, payment will be made on the next Business Day.
Redeemed shares are entitled to dividends declared the day the redemption order
is effective.
 
Neither the Trust's transfer agent nor the Trust will be responsible for any
loss, liability, cost or expense for acting upon wire instructions or upon
telephone instructions that it reasonably believes are genuine. The Trust and
its transfer agent will each employ reasonable procedures to confirm that
telephone instructions are genuine. Such procedures may include taping of
telephone conversations. If market conditions are extraordinarily active or
extraordinary circumstances exist, and you experience difficulties placing
redemption order by telephone, you may wish to consider placing your order by
other means.
 
COMPUTATION OF YIELD
 
From time to time a Fund advertises its "current yield" and "effective compound
yield." Both yield figures are based on historical earnings and are not intended
to indicate future performance. The "current yield" of the Fund refers to the
income generated by an investment in the Fund 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 "effective yield" is calculated similarly but,
when annualized, the income earned by an investment in the Fund is assumed to be
reinvested. The "effective yield" will typically be slightly higher than the
"current yield" because of the compounding effect of this assumed reinvestment.
 
The performance of Institutional Class shares will normally be higher than for
Investment Class and Cash Sweep Class shares because the Institutional Class is
not subject to distribution expenses generally charged to Investment Class and
Cash Sweep Class shares.
 
The yield of each Fund will fluctuate, and the annualization of a week's
dividend is not a representation by the Trust as to what an investment in the
Fund will actually yield in the future.
 
Each Fund may periodically compare its performance to the performance of: other
mutual funds tracked by mutual fund rating services (such as Lipper Analytical),
financial and business publications and periodicals; broad groups of comparable
mutual funds; unmanaged indices which may assume investment of dividends but
generally do not reflect deductions for administrative and management costs; or
other investment alternatives. The Funds may quote Morningstar, Inc., a service
that ranks mutual funds on the basis of risk-adjusted performance, and Ibbotson
Associates of Chicago, Illinois, which provides historical returns of the
capital markets in the U.S. The Funds may use long term performance of these
capital markets to demonstrate general long-term risk versus reward scenarios
and could include the value of a hypothetical investment in any of the capital
markets. The Funds may also quote financial and business publications and
periodicals as they relate to fund management, investment philosophy, and
investment techniques.
 
The Funds may quote various measures of volatility and benchmark correlation in
advertising and may compare these measures to those of other funds. Measures of
volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be. Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.
 
TAXES
 
The following summary of federal income tax consequences is based on current tax
laws and regulations, which may be changed by legislative, judicial or
administrative action. No attempt has been made to present a detailed
explanation of the
<PAGE>   278
 
 10
 
federal, state, or local income tax treatment of a Fund or its Shareholders. In
addition, state and local income tax consequences of an investment in a Fund may
differ from the federal income tax consequences discussed below. Accordingly,
Shareholders are urged to consult their tax advisers regarding specific
questions as to federal, state and local income taxes. Additional information
concerning taxes is set forth in the Statement of Additional Information.
 
TAX STATUS OF THE FUNDS:
 
Each Fund is treated as a separate entity for federal income tax purposes and is
not combined with the Trust's other Funds. Each Fund intends to qualify for the
special tax treatment afforded regulated investment companies under the Internal
Revenue Code of 1986, as amended (the "Code"), so as to be relieved of federal
company taxable income tax on that part of its net investment income and net
capital gain (the excess of net long-term capital gain over net short-term
capital loss) distributed to Shareholders.
 
TAX STATUS OF DISTRIBUTIONS:
 
Each Fund will distribute all of its net investment income (including net
short-term capital gain) and net capital gain to Shareholders. Dividends from
net investment company taxable income are taxable to Shareholders as ordinary
income (whether received in cash or in additional shares) to the extent of the
Fund's earnings and profits. Distributions of net capital gain are taxable to
Shareholders as long-term capital gain regardless of how long the Shareholders
have held their shares and regardless of whether the distributions are received
in cash or in additional shares. Dividends and distributions of capital gain
paid by a Fund do not qualify for the dividends received deduction for corporate
shareholders. Each Fund will provide annual reports to Shareholders of the
federal income tax status of all distributions.
 
With respect to investments in STRIPS, TR's, TIGR's and CATS which are sold at
original issue discount and thus do not make periodic cash interest payments, a
Fund will be required to include as part of its current income the imputed
interest on such obligations even though the Fund has not received any interest
payments on such obligations during that period. Because each Fund distributes
all of its net investment income to its shareholders, a Fund may have to sell
portfolio securities to distribute such imputed income which may occur at a time
when the Advisor would not have chosen to sell such securities and which may
result in a taxable gain or loss.
 
Dividends declared by a Fund in October, November or December of any year and
payable to Shareholders of record on a date in that month will be deemed to have
been paid by the Fund and received by the Shareholders on December 31 of the
year declared, if paid by the Fund any time during the following January.
 
The Funds intend to make sufficient distributions prior to the end of each
calendar year to avoid liability for the federal excise tax applicable to
regulated investment companies.
 
Income received directly by a Fund on direct U.S. obligations is exempt from tax
at the state level when received directly by a Fund and may be exempt, depending
on the state, when received by a Shareholder as income dividends from a Fund
provided certain state-specific conditions are satisfied. Interest received on
repurchase agreements collateralized by U.S. government obligations normally is
not exempt from state tax. A Fund will inform Shareholders annually of the
percentage of income and distributions derived from direct U.S. Treasury
obligations. Shareholders should consult their tax advisors to determine whether
any portion of the income dividends received from a Fund is considered tax
exempt in their particular state.
 
Income derived by a Fund from obligations of foreign issuers may be subject to
foreign withholding taxes. Each Fund will not be able to elect to treat
Shareholders as having paid their proportionate share of such foreign taxes.

Each Fund intends to make sufficient distributions prior to the end of each
calendar year to avoid liability for federal excise tax applicable to regulated
investment companies.
 
Each sale, exchange or redemption of Fund shares is a taxable event to the
Shareholder.
 
GENERAL INFORMATION
 
THE TRUST
 
The Trust was organized as a Massachusetts business trust under a Declaration of
Trust dated October 16, 1990. The Declaration of Trust permits the Trust to
offer separate portfolios of shares and different classes of each fund. In
addition to the Money Market and Treasury Money Market Funds, the Trust consists
of the following funds: Growth Equity Fund, Value Momentum Fund, Intermediate-
Term Bond Fund, Limited Maturity Government Fund, Balanced Fund, Blue Chip
Growth Fund, Emerging Growth Fund, Convertible Securities Fund, Government
Securities Fund, California Tax-Free Bond Fund, California Intermediate Tax-Free
Money Market Fund and International Equity Fund. All consideration received by
the Trust for shares of any fund and all assets of such fund belong to that fund
and would be subject to liabilities related thereto. The Trust reserves the
right to create and issue shares of additional funds.
 
The Trust pays its expenses, including audit and legal expenses, expenses of
preparing and printing prospectuses, proxy solicitation material and reports to
Shareholders, costs of custodial services and registering the shares under
federal and state securities laws, insurance expenses, litigation and other
extraordinary expenses, brokerage costs, interest charges, taxes and
organization expenses.
 
TRUSTEES OF THE TRUST
 
The management and affairs of the Trust are supervised by the Trustees under the
laws governing business trusts in the Commonwealth of Massachusetts. The
Trustees have approved contracts under which, as described above, certain
companies provide essential management, administrative and shareholder services
to the Trust.
 
VOTING RIGHTS
 
Each share held entitles the Shareholder of record to one vote. Shareholders of
each fund or class will vote separately on matters relating solely to such fund
or class. As a Massachusetts business trust, the Trust is not required to hold
annual meetings but approval will be sought for certain changes in the operation
of the Trust and for the election of Trustees under certain circumstances. In
addition, a Trustee may be removed by the remaining Trustees or by Shareholders
at a special meeting called upon the written request of Shareholders owning at
least 10% of the outstanding shares of the Trust. In the event that such a
meeting is requested the Trust will provide appropriate communication assistance
and information to the Shareholders requesting the meeting.
 
REPORTING
 
The Trust issues unaudited financial information semiannually and audited
financial statements annually. The Trust furnishes proxy statements and other
reports to Shareholders of record.
 
SHAREHOLDER INQUIRIES
 
Shareholder inquiries should be directed to the Administrator, SEI Financial
Management Corporation, 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658.
 
DIVIDENDS
 
The net investment income (exclusive of net short-term capital gain) of each
Fund is determined and declared on each business day as a dividend for
Shareholders of record as of the close of business on that day. Dividends are
paid by the Fund in additional shares, unless the Shareholder has elected to
take such payment in cash, on the first business day of each month. Shareholders
may change their election by providing written notice to the Administrator at
least 15 days prior to the change.
<PAGE>   280
 
 12
 
The dividends payable on the Cash Sweep Class shares will typically be lower
than the dividends payable on the Institutional Class shares because of the
distribution expenses charged to Cash Sweep Class shares. The dividends payable
on the Cash Sweep Class will also be less than the dividends payable on the
Investment Class shares because of the higher distribution expenses charged to
Cash Sweep Class shares.
 
COUNSEL AND INDEPENDENT PUBLIC ACCOUNTANTS
 
Morgan, Lewis & Bockius LLP serves as counsel to the Trust. Arthur Andersen LLP
serves as the independent public accountants of the Trust.
 
CUSTODIAN
 
CoreStates Bank NA., Broad and Chestnut Streets, P.O. Box 7618, Philadelphia,
Pennsylvania 19101 (the "Custodian") acts as Custodian of the assets of the
Fund. The Custodian holds cash, securities and other assets of the Trust as
required by the Investment Company Act of 1940, as amended.
 
DESCRIPTION OF PERMITTED INVESTMENTS
 
The following is a description of the permitted investments for the Funds:
 
ASSET-BACKED SECURITIES (NON-MORTGAGE)--Instruments secured by company
receivables, truck and auto loans, leases, and credit card receivables. Such
securities are generally issued as pass-through certificates, which represent
undivided fractional ownership interests in the underlying pools of assets. Such
securities also may be debt instruments, which are also known as collateralized
obligations and are generally issued as the debt of a special purpose entity,
such as a trust, organized solely for purpose of owning such assets and issuing
such debt. The purchase of non-mortgage asset-backed securities raises risk
considerations peculiar to the financing of the instruments underlying such
securities. Asset-backed securities entail prepayment risk, which may vary
depending on the type of asset.
 
BANKERS' ACCEPTANCE--Bills of exchange or time drafts drawn on and accepted by
commercial banks. They are used by corporations to finance the shipment and
storage of goods and to furnish dollar exchange. Maturities are generally six
months or less.
 
CERTIFICATES OF DEPOSIT--Negotiable interest-bearing instruments with a specific
maturity. Certificates of deposit are issued by banks and savings and loan
institutions in exchange for the deposit of funds and normally can be traded in
the secondary market, prior to maturity.
 
COMMERCIAL PAPER--Unsecured short-term promissory notes issued by corporations
and other entities. Maturities on these issues vary from a few days to nine
months. Purchase of such instruments involves a risk of default by the issuer.
 
DERIVATIVES--Instruments whose value is derived from an underlying contract,
index or security, or any combination thereof, including futures, options (e.g.,
puts and calls), options on futures, swap agreements, and some mortgage-backed
securities (CMOs, REMICs, IOs and POs). See elsewhere in this "Description of
Permitted Investments" for discussions of these various instruments, and see
"Investment Objectives and Policies" for more information about any policies and
limitations applicable to their use.
 
LOAN PARTICIPATIONS--Interests in loans to U.S. corporations (i.e., borrowers)
administered by the lending bank or agent for a syndicate of lending banks, and
sold by the lending bank or syndicate member ("intermediary bank"). Because the
intermediary bank does not guarantee a loan participation in any way, a loan
participation is subject to the credit risks generally associated with the
underlying corporate borrower. In addition, in the event the underlying
corporate borrower fails to pay principal and interest when due, the Fund may be
subject to delays, expenses and risks that are greater than those that would
have been involved if the Fund had purchased a direct obligation (such as
commercial paper) of such borrower. Moreover, the purchasing Fund may be
regarded as a creditor of the intermediary bank
<PAGE>   281
 
 13
 
(rather than of the underlying corporate borrower), making it subject to the
risk that the issuing bank may become insolvent. Further, in the event of the
bankruptcy or insolvency of the corporate borrower, a loan participation may be
subject to certain defenses that can be asserted by such borrower as a result of
improper conduct by the issuing bank. The secondary market, if any, for these
loan participations is limited, and any such participation purchased by the Fund
may be regarded as illiquid.
 
RULE 144A SECURITIES--Rule 144A Securities are securities that have not been
registered under the Securities Act of 1933 but which may be traded between
certain qualified institutional investors, including investment companies. The
absence of a secondary market may affect the value of Rule 144A Securities. The
Board of Trustees of the Trust has established guidelines and procedures to be
utilized to determine the liquidity of such securities.
 
REPURCHASE AGREEMENTS--Agreements by which a Fund obtains a security and
simultaneously commits to return the security to the seller at an agreed upon
price (including principal and interest) on an agreed upon date within a number
of days from the date of purchase. A Fund will have actual or constructive
possession of the securities held as collateral for the repurchase agreement. A
Fund bears a risk of loss in the event the other party defaults on its
obligations and the Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities or if a Fund realizes a loss on the sale of
the collateral. A Fund will enter into repurchase agreements only with financial
institutions deemed to present minimal risk of bankruptcy during the term of the
agreement based on established guidelines. Repurchase agreements are considered
loans under the 1940 Act.
 
SECURITIES ISSUED ON A FORWARD COMMITMENT BASIS OR WHEN-ISSUED
SECURITIES--Securities subject to settlement on a future date. The interest rate
realized on these securities is fixed as of the purchase date and no interest
accrues to a Fund before settlement. These securities are subject to market
fluctuation due to changes, real or anticipated, in market interest rates and
the public's perception of the creditworthiness of the issuer and will have the
effect of leveraging the Fund's assets. Purchasing securities on a forward
commitment or when-issued basis when a Fund is fully or almost fully invested
may result in greater potential fluctuation in the value of a Fund's net asset
value per share. The purchasing Fund will establish one or more segregated
accounts with the Custodian, and will maintain liquid, high grade assets in an
amount at least equal in value to the Fund's commitments to purchase when-issued
securities.
 
SECURITIES LENDING--In order to generate additional income, each Fund may lend
the securities in which it is invested pursuant to agreements requiring that the
loan be continuously secured by cash, securities of the U.S. Government or its
agencies or any combination of cash and such securities as collateral equal to
100% of the market value at all times of the loaned securities. The lending Fund
will continue to receive interest on the loaned securities while simultaneously
earning interest on the investment of cash collateral. Collateral is marked to
market daily to provide a level of collateral at least equal to the value of the
loaned securities. There may be risks of delay in receiving additional
collateral or risks of delay in recovery of the securities or even loss of
rights in the collateral should the borrower of the securities fail financially.
 
TIME DEPOSITS--Non-negotiable receipts issued by U.S. or foreign banks in
exchange for the deposit of funds. Like certificates of deposit, they earn a
specified rate of interest over a definite period of time; however, they cannot
be traded in the secondary market. Time deposits with a withdrawal penalty are
considered to be illiquid securities.
 
U.S. GOVERNMENT AGENCY SECURITIES-- Certain Federal agencies have been
established as instrumentalities of the U.S. Government to supervise and finance
certain types of activities. Issues of these agencies, while not direct
obligations of the U.S. Government, are either backed by the full faith and
credit of the United
<PAGE>   282
 
 14
 
States (e.g., GNMA securities) or supported by the issuing agencies' right to
borrow from the Treasury. The issues of other agencies are supported only by the
credit of the instrumentality (e.g., FNMA securities).
 
U.S. TREASURY OBLIGATIONS--Bills, notes and bonds issued by the U.S. Treasury,
as well as separately traded interest and principal component parts of such
obligations known as Separately Traded Registered Interest and Principal
Securities ("STRIPS") that are transferable through the Federal book-entry
system.
 
RECEIPTS--Interests in separately traded interest and principal component parts
of U.S. Treasury obligations that are issued by banks or brokerage firms and are
created by depositing Treasury notes and Treasury bonds into a special account
at a custodian bank. The custodian holds the interest and principal payments for
the benefit of the registered owners of the certificates or receipts. The
custodian arranges for the issuance of the certificates or receipts evidencing
ownership and maintains the register. Receipts include "Treasury Receipts"
("TR's"), "Treasury Investment Growth Receipts" ("TIGR's") and "Certificates of
Accrual on Treasury Securities" ("CATS"). TR'S, TIGR'S and CATS are sold as zero
coupon securities, which means that they are sold at a substantial discount and
redeemed at face value at their maturity date without interim cash payments of
interest or principal. This discount is accreted over the life of the security,
and such accretion will constitute the income earned on the security for both
accounting and tax purposes. Because of these features, such securities may be
subject to greater interest rate volatility than interest paying securities. See
also "Taxes."
 
VARIABLE AND FLOATING RATE INSTRUMENTS--Obligations that may carry variable or
floating rates of interest, may involve conditional or unconditional demand
features and may include variable amount master demand notes. The interest rates
on these securities may be reset daily, weekly, quarterly or some other reset
period, and may have a floor or ceiling on interest rate changes. There is a
risk that the current interest rate on such obligations may not accurately
reflect existing market interest rates. A demand instrument with a demand notice
period exceeding seven days may be considered illiquid if there is no secondary
market for such security.
 
RESTRAINTS ON INVESTMENTS BY MONEY MARKET FUNDS
 
Investments by the Funds are subject to limitations imposed under regulations
adopted by the SEC. These regulations generally require money market funds to
acquire only U.S. dollar denominated obligations maturing in 397 days or less
and to maintain a dollar-weighted average portfolio maturity of 90 days or less.
In addition, the Funds may acquire only obligations that present minimal credit
risks and that are "eligible securities" which means they are (i) rated, at the
time of investment, by at least two nationally recognized statistical rating
organizations (one if it is the only organization rating such obligation) in the
highest short-term rating category or, if unrated, determined to be of
comparable quality (a "first tier security"), or (ii) rated according to the
foregoing criteria in the second highest short-term rating category or, if
unrated, determined to be of comparable quality ("second tier security"). A
security is not considered to be unrated if its issuer has outstanding
obligations of comparable priority and security that have a short-term-rating.
In determining whether obligations are eligible securities, the rating of the
issuer's commercial paper, if any, is used for the above tests. Investments by
the Money Market Fund in second tier securities are subject to the further
constraints that (i) no more than 5% of the Fund's assets may be invested in
such securities in the aggregate, and (ii) any investment in such securities of
one issuer is limited to the greater of 1% of the Fund's total assets or $1
million. In addition, the Fund may invest up to 25% of its total assets in the
first tier securities of a single issuer for three business days.

THE TRUST

Stepstone Funds (formerly Union Investors Funds) (the "Trust") is a
diversified, open-end management investment company established under
Massachusetts law as a business trust pursuant to a Declaration of Trust dated
October 16, 1990.  The Trust changed its name on May 12, 1992, from Union
Investors Portfolios to Union Investors Funds.  On March 1, 1994, the Trust
changed its name from Union Investors Funds to its current name, Stepstone
Funds.  The Declaration of Trust permits the Trust to offer separate series of
shares of beneficial interest ("shares") and different classes of shares of
each Fund.  Shareholders may purchase shares through two separate classes
(Institutional and Investment Classes) of twelve of the Trust's Funds and
through three separate classes (Institutional, Investment and Cash Sweep
Classes) of two of the Trust's Funds, which provide for variations in
distribution costs, voting rights and dividends.  Except for these differences
among Institutional, Investment and Cash Sweep Class shares, each share of
each Fund represents an equal proportionate interest in that Fund.  See
"Description of Shares."  This Statement of Additional Information relates to
the Institutional Class and Investment Class shares of the Trust's
International Equity, Balanced, Blue Chip Growth, California Intermediate
Tax-Free Bond, California Tax-Free Money Market, Convertible Securities,
Emerging Growth, Government Securities, Growth Equity, Intermediate-Term Bond,
Limited Maturity Government, Money Market, Treasury Money Market, and Value
Momentum Funds and the Cash Sweep Class shares of the Money Market and Treasury
Money Market Funds (the "Funds").


DESCRIPTION OF PERMITTED INVESTMENTS


The following information supplements the information about permitted
investments set forth in the Prospectuses.


VARIABLE AMOUNT MASTER DEMAND NOTES.  Certain of the permitted investments of
the Funds may include VARIABLE AMOUNT MASTER DEMAND NOTES, which may or may not
be backed by bank letters of credit.  These notes permit the investment of
fluctuating amounts at varying market rates of interest pursuant to direct
arrangements between the Trust, as lender, and the borrower.  Such notes
provide that the interest rate on the amount outstanding varies on a daily,
weekly or monthly basis depending upon a stated short-term interest rate index.
Both the lender and the borrower have the right to reduce the amount of
outstanding indebtedness at any time.  There is no secondary market for the
notes.  It is not generally contemplated that such instruments will be traded.


SHARES OF OTHER INVESTMENT COMPANIES.  A Fund's purchase of investment company
securities will result in the layering of expenses.  A Fund is prohibited from
acquiring the securities of other investment companies if, as a result of such
acquisition, the Fund owns in the aggregate (1) more than 3% of the total
outstanding voting stock of the acquired company, (2) securities issued by the
acquired company having an aggregate value in excess of 5% of the value of the
total assets of the Fund, or (3) securities issued by the acquired company and
all other investment companies having an aggregate value in excess of 10% of
the value of the total assets of the Fund.


GNMA SECURITIES.  Certain of the Funds may invest in SECURITIES ISSUED BY THE
GOVERNMENT NATIONAL MORTGAGE ASSOCIATION ("GNMA"), a wholly-owned U.S.
Government corporation which guarantees the timely payment of principal and
interest.  The market value and interest yield of these instruments can vary
due to market interest rate fluctuations and early prepayments of underlying
mortgages.  These securities represent ownership in a pool of federally insured
mortgage loans.  GNMA certificates consist of underlying mortgages with a
maximum maturity of 30 years.  However, due to scheduled and unscheduled
principal payments, GNMA certificates have a shorter average maturity and,
therefore, less principal volatility than a comparable 30-year bond.  Since
prepayment





                                      S-2

<PAGE>   286
rates vary widely, it is not possible to predict accurately the average
maturity of a particular GNMA pool.  The scheduled monthly interest and
principal payments relating to mortgages in the pool will be "passed through"
to investors.  GNMA securities differ from conventional bonds in that principal
is paid back to the certificate holders over the life of the loan rather than
at maturity.  As a result, there will be monthly scheduled payments of
principal and interest.  In addition, there may be unscheduled principal
payments representing prepayments on the underlying mortgages.  Although GNMA
certificates may offer yields higher than those available from other types of
U.S. Government securities, GNMA certificates may be less effective than other
types of securities as a means of "locking in" attractive long-term rates
because of the prepayment feature.  For instance, when interest rates decline,
the value of a GNMA certificate likely will not rise as much as comparable debt
securities due to the prepayment feature.  In addition, these prepayments can
cause the price of a GNMA certificate originally purchased at a premium to
decline in price to its par value, which may result in a loss.

MORTGAGE-BACKED SECURITIES.  The Intermediate-Term Bond, Balanced, Government
Securities and Limited Maturity Government Funds may invest in MORTGAGE-BACKED
SECURITIES.  Two types of mortgage-backed securities are
collateralized mortgage obligations ("CMOs") and real estate mortgage
investment conduits ("REMICS"), which are rated in one of the two top
categories by S&P or Moody's.  CMOs are securities collateralized by mortgages,
mortgage pass-throughs, mortgage pay-through bonds (bonds representing an
interest in a pool of mortgages where the cash flow generated from the mortgage
collateral pool is dedicated to bond repayment), and mortgage-backed bonds
(general obligations of the issuers payable out of the issuers' general funds
and additionally secured by a first lien on a pool of single family detached
properties).  Many CMOs are issued with a number of classes or series which
have different maturities and are retired in sequence.

Investors purchasing such CMOs in the shortest maturities receive or are
credited with their pro rata portion of the scheduled payments of interest and
principal on the underlying mortgages, plus all unscheduled prepayments of
principal up to a predetermined portion of the total CMO obligation.  Until
that portion of such CMO obligation is repaid, investors in the longer
maturities receive interest only.  Accordingly, the CMOs in the longer maturity
series are less likely than other mortgage pass-throughs to be prepaid prior to
their stated maturity.  Although some of the mortgages underlying CMOs may be
supported by various types of insurance, and some CMOs may be backed by GNMA
certificates or other mortgage pass-throughs issued or guaranteed by U.S.
Government agencies or instrumentalities, the CMOs themselves are not generally
guaranteed.

REMICs, which were authorized under the Tax Reform Act of 1986, are private
entities formed for the purpose of holding a fixed pool of mortgages secured by
an interest in real property.  REMICs are similar to CMOs in that they issue
multiple classes of securities.


ASSET-BACKED SECURITIES.  The Intermediate-Term Bond, Money Market, Balanced
and Government Securities Funds may invest in readily marketable ASSET-BACKED
SECURITIES backed by corporate receivables, truck and auto loans, leases, and
credit card receivables.  These issues may be traded over-the-counter and
typically have a short-intermediate maturity structure depending on the paydown
characteristics of the underlying assets which are passed through to the
security holder.


REPURCHASE AGREEMENTS.  REPURCHASE AGREEMENTS are agreements by which a
Fund obtains a security and simultaneously commits to return the security to
the seller (a member bank of the Federal Reserve System or recognized
securities dealer) at an agreed upon price (including principal and interest)
on an agreed upon date within a number of days (usually not more than seven)
from the date of purchase.  The repurchase price reflects the purchase price
plus an agreed upon market rate of interest which is unrelated to the coupon
rate or maturity of the underlying security.  A repurchase agreement





                                      S-3

<PAGE>   287
involves the obligation of the seller to pay the agreed upon price, which
obligation is in effect secured by the value of the underlying security.

Repurchase agreements are considered to be loans by the Fund for
purposes of its investment limitations.  The repurchase agreements entered into
by the Funds will provide that the underlying security at all times shall have
a value at least equal to 102% of the repurchase price stated in the agreement
(the Advisor monitors compliance with this requirement).  Under all repurchase
agreements entered into by the Funds, the Custodian or its agent must take
possession of the underlying collateral.  However, if the seller defaults, the
Funds could realize a loss on the sale of the underlying security to the extent
that the proceeds of sale including accrued interest are less than the
repurchase price provided in the agreement including interest.  In addition,
even though the Bankruptcy Code provides protection for most repurchase
agreements, if the seller should be involved in bankruptcy or insolvency
proceedings, the Funds may incur delay and costs in selling the underlying
security or may suffer a loss of principal and interest if the Funds are
treated as an unsecured creditor and required to return the underlying security
to the seller's estate.


MUNICIPAL SECURITIES.  MUNICIPAL NOTES in which the California Tax-Free Money
Market and California Intermediate Tax-Free Bond Funds may invest, include, but
are not limited to, general obligation notes, tax anticipation notes (notes
sold to finance working capital needs of the issuer in anticipation of
receiving taxes on a future date), revenue anticipation notes (notes sold to
provide needed cash prior to receipt of expected non-tax revenues from a
specific source), bond anticipation notes, certificates of indebtedness, demand
notes and construction loan notes.  The Fund's investments in any of the notes
described above will be limited to those obligations (i) where both principal
and interest are backed by the full faith and credit of the United States, (ii)
which are rated MIG-2 or V-MIG-2 at the time of investment by Moody's Investors
Service ("Moody's"), (iii) which are rated SP-2 at the time of investment by
Standard and Poor's Corporation ("S&P"), (iv) which are rated F-1 at the time
of investment by Fitch Investors Service, Inc. ("Fitch") or (v) which, if not
rated, are of equivalent quality in the Advisor's judgment, to MIG-2, V-MIG-2,
SP-2 or F-1.


MUNICIPAL BONDS, in which the California Tax-Free Money Market and California
Intermediate Tax-Free Bond Funds may invest, must be rated AA or better S&P or
Fitch or Aa or better by Moody's at the time of investment for the California
Tax-Free Money Market Fund or, if purchased for the California Intermediate
Tax-Free Bond Fund, rated BBB or better by S&P or Fitch or Baa or better by
Moody's, or, if unrated, be deemed by the Advisor to have essentially the same
characteristics and quality as bonds having the above ratings.  The Advisor may
purchase private activity bonds if the interest paid is excludable from Federal
income tax.  Private activity bonds are issued by or on behalf of States or
political subdivisions thereof to finance privately owned or operated
facilities for business and manufacturing, housing, sports, and pollution
control and to finance activities of and facilities for charitable
institutions.  Private activity bonds are also used to finance public
facilities such as airports, mass transit systems, ports, parking and low
income housing.  The payment of the principal and interest on private activity
bonds is dependent solely on the ability of the facility's user to meet its
financial obligations and may be secured by a pledge of real and personal
property so financed.


California municipal securities, which are payable only from the revenues
derived from a particular facility, may be adversely affected by California
laws or regulations which make it more difficult for the particular facility to
generate revenues sufficient to pay such interest and principal, including,
among others, laws and regulations which limit the amount of fees, rates or
other charges which may be imposed for use of the facility or which increase
competition among facilities of that type or which limit or otherwise have the
effect of reducing the use of such facilities generally, thereby reducing the
revenues generated by the particular facility.  California municipal
securities, the payment of interest and principal on which is insured in whole
or in part by a California governmentally created fund, may





                                      S-4

<PAGE>   288
be adversely affected by California laws or regulations which restrict the
aggregate insurance proceeds available for payment of principal and interest in
the event of a default on such municipal securities.  Similarly, California
municipal securities, the payment of interest and principal on which is
secured, in whole or in part, by an interest in real property, may be adversely
affected by California laws which limit the availability of remedies or the
scope of remedies available in the event of a default on such municipal
securities.  Because of the diverse nature of such laws and regulations and the
impossibility of either predicting in which specific California municipal
securities the Funds will invest from time to time or predicting the nature or
extent of future changes in existing laws or regulations or the future
enactment or adoption of additional laws or regulations, it is not presently
possible to determine the impact of such laws and regulations on the municipal
securities in which the Funds may invest and, therefore, on the shares of the
Funds.


TAX-EXEMPT COMMERCIAL PAPER will be limited to investments in obligations which
are rated at least A-2 by S&P, F-2 by Fitch or Prime-2 by Moody's at the time
of investment or which are determined by the Advisor to be of equivalent
quality.



Other types of TAX-EXEMPT INSTRUMENTS which are permissible investments for the
California Tax-Free Money Market and California Intermediate Tax-Free Bond
Funds include floating rate notes.  Investments in such floating rate
instruments will normally involve industrial development or revenue bonds which
provide that the rate of interest is set as a specific percentage of a
designated base rate (such as the prime rate) at a major commercial bank, and
that a Fund can demand payment of the obligation at all times, or at stipulated
dates on short notice (not to exceed 30 days), at par plus accrued interest.
The Funds may use the longer of the period required before a Fund is entitled
to prepayment under such obligations or the period remaining until the next
interest rate adjustment date for purposes of determining the maturity.  Such
obligations are frequently secured by letters of credit or other credit support
arrangements provided by banks.  The quality of the underlying credit or of the
bank, as the case may be, must, in the Advisor's opinion, be equivalent to the
long-term bond or commercial paper ratings stated above.  The Advisor will
monitor the earning power, cash flow and liquidity ratios of the issuers of
such instruments, and the ability of an issuer of a demand instrument to pay
principal and interest on demand.  The Advisor may purchase other types of
tax-exempt instruments, as long as they are of a quality equivalent to the bond
or commercial paper ratings stated above.


The Advisor has the authority to purchase securities at a price which would
result in a yield to maturity lower than that generally offered by the seller
at the time of purchase when it can simultaneously acquire the right to sell
the securities back to the seller, the issuer, or a third party (the "writer")
at an agreed-upon price at any time during a stated period or on a certain
date.  Such a right is generally denoted as a "standby commitment" or a "put."
The purpose of engaging in transactions involving puts is to maintain
flexibility and liquidity to permit the California Tax-Free Money Market and
California Intermediate Tax-Free Bond Funds to meet redemptions and remain as
fully invested as possible in municipal securities.  The Funds reserve the
right to engage in put transactions.  The right to put the securities depends
on the writer's ability to pay for the securities at the time the put is
exercised.  The Funds limit their put transactions to institutions which the
Advisor believes present minimum credit risks, and the Advisor uses its best
efforts to initially determine and continue to monitor the financial strength
of the sellers of the puts by evaluating their financial statements and such
other information as is available in the marketplace.  It may, however, be
difficult to monitor the financial strength of the writers because adequate
current financial information may not be available.  In the event that any
writer is unable to honor a put for financial reasons, the affected Fund would
be a general creditor (i.e., on a parity with all other unsecured creditors) of
the writer.  Furthermore, particular provisions of the contract between a Fund
and the writer may excuse the writer from repurchasing the securities; for
example, a change in the published rating of the underlying municipal
securities or any similar event





                                      S-5

<PAGE>   289
that has an adverse effect on the issuer's credit or a provision in the
contract that the put will not be exercised except in certain special cases,
for example, to maintain portfolio liquidity.  A Fund could, however, at any
time sell the underlying portfolio security in the open market or wait until
the portfolio security matures, at which time it should realize the full par
value of the security.


The municipal securities purchased subject to a put may be sold to third
persons at any time, even though the put is outstanding, but the put itself,
unless it is an integral part of the security as originally issued, may not be
marketable or otherwise assignable.  Therefore, the put would have value only
to a Fund.  Sale of the securities to third parties or lapse of time with the
put unexercised may terminate the right to put the securities.  Prior to the
expiration of any put option, a Fund could seek to negotiate terms for the
extension of such an option.  If such a renewal cannot be negotiated on terms
satisfactory to a Fund, such Fund could, of course, sell the portfolio
security.  The maturity of the underlying security will generally be different
from that of the put.  There will be no limit to the percentage of portfolio
securities that the Funds may purchase subject to a put, but the amount paid
directly or indirectly for puts which are not integral parts of the security as
originally issued held in either Fund will not exceed 1/2 of 1% of the value of
the total assets of such Funds calculated immediately after any such put is
acquired.  For the purpose of determining the "maturity" of securities
purchased subject to an option to put, and for the purpose of determining the
dollar-weighted average maturity of the Funds including such securities, the
Trust will consider "maturity" to be the first date on which it has the right
to demand payment from the writer of the put although the final maturity of the
security is later than such date.


SPECIAL CONSIDERATIONS RELATING TO CALIFORNIA MUNICIPAL SECURITIES


The ability of issuers to pay interest on, and repay principal of, California
municipal securities ("California Municipal Securities") may be affected by (1)
amendments to the California Constitution and related statutes that limit the
taxing and spending authority of California government entities, (2) voter
initiatives, (3) a wide variety of California laws and regulations, including
laws related to the operation of health care institutions and laws related to
secured interests in real property and (4) the general financial condition of
the State of California. The following information constitutes only a brief
summary, and is not intended as a complete description. The information has
been drawn, in some cases by excerpt, from official statements relating to
securities offerings of the State of California available as of the date of
this Statement of Additional Information.  While the information has not been
independently verified by the California Tax-Free Money Market and California
Intermediate Tax-Free Bond Funds, these Funds have no reason to believe that
such information is not correct in all material respects.


Amendments to the California Constitution and Related Statutes.  Certain of the
California Municipal Securities may be obligations of issuers who rely in whole
or in part on ad valorem real property taxes as a source of revenue.  On June
6, 1978, California voters approved an amendment to the California Constitution
known as Proposition 13, which added Article XIIIA to the California
Constitution.  The effect of Article XIIIA is to limit ad valorem taxes on real
property, and to restrict the ability of taxing entities to increase real
property tax revenues.  On November 7, 1978, California voters approved
Proposition 8, and on June 3, 1986, California voters approved Proposition 46,
both of which amended Article XIIIA.

Section 1 of Article XIIIA limits the maximum ad valorem tax on real property
to 1% of full cash value (as defined in Section 2), to be collected by the
counties and apportioned according to law; provided that the 1% limitation does
not apply to ad valorem taxes or special assessments to pay the interest and
redemption charges on (i) any indebtedness approved by the voters prior to July
1, 1978, or (ii) any bonded indebtedness for the acquisition or improvement of
real property approved on or after July 1, 1978, by two-thirds of the votes
cast by the voters voting on the proposition.  Section 2 of Article





                                      S-6

<PAGE>   290
XIIIA defines "full cash value" to mean "the County Assessor's valuation of
real property as shown on the 1975/76 tax bill under 'full cash value' or,
thereafter, the appraised value of real property when purchased, newly
constructed, or a change in ownership has occurred after the 1975 assessment."
The "full cash value" may be adjusted annually to reflect inflation at a rate
not to exceed 2% per year, or reduction in the consumer price index or
comparable local data, or reduced in the event of declining property value
caused by damage, destruction or other factors.  The California State Board of
Equalization has adopted regulations, binding on county assessors, interpreting
the meanings of "change in ownership" and "new construction" for purposes of
determining full cash value of property under Article XIIIA.

Legislation enacted by the California Legislature to implement Article XIIIA
(Statutes of 1978, Chapter 292, as amended) provides that notwithstanding any
other law, local agencies may not levy any ad valorem property tax except to
pay debt service on indebtedness approved by the voters prior to July 1, 1978,
and that each county will levy the maximum tax permitted by Article XIIIA of
$4.00 per $100 assessed valuation (based on the former practice of using 25%,
instead of 100%, of full cash value as the assessed value for tax purposes).
The legislation further provided that, for the 1978/79 fiscal year only, the
tax levied by each county was to be apportioned among all taxing agencies
within the county in proportion to their average share of taxes levied in
certain previous years.  The apportionment of property taxes in fiscal years
after 1978/79 has been revised pursuant to Statutes of 1979, Chapter 282, which
provides relief funds from State moneys beginning in fiscal year 1979/80 and is
designed to provide a permanent system for sharing State taxes and budget funds
with local agencies.  Under Chapter 282, cities and counties receive more of
the remaining property tax revenues collected under Proposition 13 instead of
direct State aid.  School districts receive a correspondingly reduced amount of
property taxes, but receive compensation directly from the State and are given
additional relief.  Chapter 282 does not affect the derivation of the base levy
($4.00 per $100 of assessed valuation) and the bonded debt tax rate.

On November 6, 1979, an initiative known as "Proposition 4" or the "Gann
Initiative" was approved by the California voters, which added Article XIIIB to
the California Constitution.  Under Article XIIIB, State and local governmental
entities have an annual "appropriations limit" and are not allowed to spend
certain moneys called "appropriations subject to limitation" in an amount
higher than the "appropriations limit."  Article XIIIB does not affect the
appropriation of moneys which are excluded from the definition of
"appropriations subject to limitation," including debt service on indebtedness
existing or authorized as of January 1, 1979, or bonded indebtedness
subsequently approved by the voters.  In general terms, the "appropriations
limit" is required to be based on certain 1978/79 expenditures, and is to be
adjusted annually to reflect changes in consumer prices, population and certain
services provided by these entities.  Article XIIIB also provides that if these
entities' revenues in any year exceed the amounts permitted to be spent, the
excess is to be returned by revising the tax rates or fee schedules over the
subsequent two years.

Article XIIIB, like XIIIA, may require further interpretation by both the
Legislature and the courts to determine its applicability to specific
situations involving the State and local taxing authorities.  Depending upon
the interpretation, Article XIIIB may limit significantly a governmental
entity's ability to budget sufficient funds to meet debt service on bonds and
other obligations.

Voter Initiatives.  On November 8, 1988, voters of the State approved
Proposition 98, a combined initiative constitutional amendment and statute
called the "Classroom Instructional Improvement and Accountability Act."
Proposition 98 changed State funding of public education below the university
level and the operation of the State Appropriations Limit, primarily by
guaranteeing K-14 schools a minimum share of General Fund revenues.  Under
Proposition 98 (as modified by Proposition 111, which was enacted on June 5,
1990), K-14 schools are guaranteed the greater of (a) in general, a fixed
percent of General Fund revenues ("Test 1"), (b) the amount appropriated to
K-14 schools in the





                                      S-7

<PAGE>   291
prior year, adjusted for changes in the cost of living (measured as in Article
XIII B by reference to State per capita personal income) and enrollment ("Test
2"), or (c) a third test, which would replace "Test 2" in any year when the
percentage growth in per capita General Fund revenues from the prior year plus
one half of one percent is less than the percentage growth in State per capita
personal income ("Test 3").  Under "Test 3," schools would receive the amount
appropriated in the prior year adjusted for changes in enrollment and per
capita General Fund revenues, plus an additional small adjustment factor.  If
"Test 3" is used in any year, the difference between "Test 3" and "Test 2"
would become a "credit" to schools which would be the basis of payments in
future years when per capita General Fund revenue growth exceeds per capita
personal income growth.  Legislation adopted prior to the end of the 1988-89
Fiscal Year, implementing Proposition 98, determined the K-14 schools' funding
guarantee under Test 1 to be 40.3 percent of the General Fund Tax revenues,
based on 1986-87 appropriations.  However, that percent would be adjusted to
account for redirection of local property taxes, since such a subsequent
redirection directly affects the share of General Fund revenues to schools.

Proposition 98 permits the Legislature by two-thirds vote of both houses, with
the Governor's concurrence, to suspend the K-14 schools' minimum funding
formula for a one-year period.  Proposition 98 also contains provisions
transferring certain State tax revenues in excess of the Article XIII B limit
to K-14 schools.


During the recent recession, General Fund revenues for several years were less
than originally projected, so that the original Proposition 98 appropriations
turned out to be higher than the minimum percentage provided in the law.  The
Legislature responded to these developments by designating the "extra"
Proposition 98 payments in one year as a "loan" from future years' Proposition
98 entitlements, and also intended that the "extra" payments would not be
included in the Proposition 98 "base" for calculating future years'
entitlements.  By implementing these actions, per-pupil funding from
Proposition 98 sources stayed almost constant at approximately $4,220 from
Fiscal Year 1991-92 to Fiscal Year 1993-94.


In 1992, a lawsuit was filed, called CALIFORNIA TEACHERS' ASSOCIATION V. GOULD,
which challenged the validity of these off-budget loans.  As part of the
negotiations leading to the 1995-96 Budget Act, an oral agreement was reached
to settle this case.  It is expected that a formal settlement reflecting these
conditions will be entered into in  the near future.


The oral agreement provides that both the State and K-14 schools share in the
repayment of prior years' emergency loans to schools.  Of the total $1.76
billion in loans, the State will repay $935 million by forgiveness of the
amount owed, while schools will repay $825 million.  The State share of the
repayment will be reflected as expenditures above the current Proposition 98
base calculation.  The schools' share of the repayment will count as
appropriations that count toward satisfying the Proposition 98 guarantee, or
from "below" the current base.  Repayments are spread over the eight-year
period of 1994-95 through 2001-02 to mitigate any adverse fiscal impact.  Once
a court settlement is reached, and the Director of Finance certifies that such
a settlement has occurred, approximately $377 million in appropriations from
the 1995-96 Fiscal Year to schools will be disbursed in August 1996.


On November 4, 1986, California voters approved an initiative statute known as
Proposition 62.  This initiative (i) requires that any tax for general
governmental purposes imposed by local governments be approved by resolution or
ordinance adopted by a two-thirds vote of the governmental entity's legislative
body and by a majority vote of the electorate of the governmental entity, (ii)
requires that any special tax (defined as taxes levied for other than general
governmental purposes) imposed by a local governmental entity be approved by a
two-thirds vote of the voters within that jurisdiction, (iii)





                                      S-8

<PAGE>   292
restricts the use of revenues from a special tax to the purposes or for the
service for which the special tax was imposed, (iv) prohibits the imposition of
ad valorem taxes on real property by local governmental entities except as
permitted by Article XIIIA, (v) prohibits the imposition of transaction taxes
and sales taxes on the sale of real property by local governments, (vi)
requires that any tax imposed by a local government on or after August 1, 1985
be ratified by a majority vote of the electorate within two years of the
adoption of the initiative or be terminated by November 15, 1988, (vii)
requires that, in the event a local government fails to comply with the
provisions of this measure, a reduction in the amount of property tax revenue
allocated to such local government occurs in an amount equal to the revenues
received by such entity attributable to the tax levied in violation of the
initiative, and (viii) permits these provisions to be amended exclusively by
the voters of the State of California.


In September 1988, the California Court of Appeal in City of Westminster v.
County of Orange 204 Cal. App. 3d 623, 215 Cal. Rptr.  511 (Cal. Ct. App.
1988), held that Proposition 62 is unconstitutional to the extent that it
requires a general tax by a general law city, enacted on or after August 1,
1985 and prior to the effective date of Proposition 62, to be subject to
approval by a majority of voters.  The Court held that the California
Constitution prohibits the imposition of a requirement that local tax measures
be submitted to the electorate by either referendum or initiative.  It is not
possible to predict the impact of this decision on charter cities, on special
taxes, or on new taxes imposed after the effective date of Proposition 62.


On November 8, 1988, California voters approved Proposition 87.  Proposition 87
amended Article XVI, Section 16, of the California Constitution by authorizing
the California Legislature to prohibit redevelopment agencies from receiving
any of the property tax revenue raised by increased property tax rates levied
to repay bonded indebtedness of local governments which is approved by voters
on or after January 1, 1989.  It is not possible to predict whether the
California Legislature will enact such a prohibition nor is it possible to
predict the impact of Proposition 87 on redevelopment agencies and their
ability to make payments on outstanding debt obligations.


Other Relevant California Laws.  A wide variety of California laws and
regulations may affect, directly or indirectly, the payment of interest on, or
the repayment of the principal of, California Municipal Securities in which the
California Tax-Free Money Market and California Intermediate Tax-Free Bond
Funds may invest.  The impact of such laws and regulations on particular
California Municipal Securities may vary depending upon numerous factors
including, among others, the particular type of Municipal Security involved,
the public purpose funded by the Municipal Security and the nature and extent
of insurance or other security for payment of principal and interest on the
Municipal Security.  For example, California Municipal Securities which are
payable only from the revenues derived from a particular facility may be
adversely affected by California laws or regulations which make it more
difficult for the particular facility to generate revenues sufficient to pay
such interest and principal, including, among others, laws and regulations
which limit the amount of fees, rates or other charges which may be imposed for
use of the facility or which increase competition among facilities of that type
or which limit or otherwise have the effect of reducing the use of such
facilities generally, thereby reducing the revenues generated by the particular
facility.  California Municipal Securities, the payment of interest and
principal on which is insured in whole or in part by a California
governmentally created fund, may be adversely affected by California laws or
regulations which restrict the aggregate insurance proceeds available for
payment of principal and interest in the event of a default on such Municipal
Securities.


Certain California Municipal Securities in which the Tax-Free Money Market and
California Intermediate Tax-Free Bond Funds may invest may be obligations that
are payable solely from the revenues of health care institutions.  Certain
provisions under California law may adversely affect such revenues and,
consequently, payment on those California Municipal Securities.

The Federally sponsored Medicaid program for health care services to eligible
welfare beneficiaries in California is known as the Medi-Cal program.
Historically, the Medi-Cal program has provided for a cost-based system of
reimbursement for inpatient care furnished to Medi-Cal beneficiaries by any
hospital wanting to participate in the Medi-Cal program, provided such hospital
met applicable requirements for participation.  California law now provides
that the State of California shall selectively contract with hospitals to
provide acute inpatient services to Medi-Cal patients.  Medi-Cal contracts
currently apply only to acute inpatient services.  Generally, such selective
contracting is made on a flat per diem payment basis for all services to
Medi-Cal beneficiaries, and generally such payment has not increased in
relation to inflation, costs or other factors.  Other reductions or limitations
may be imposed in payment for services rendered to Medi-Cal beneficiaries in
the future.

Under this approach, in most geographical areas of California, only those
hospitals which enter into a Medi-Cal contract with the State of California
will be paid for non-emergency acute inpatient services rendered to Medi-Cal
beneficiaries.  The State may also terminate these contracts without notice
under certain circumstances and is obligated to make contractual payments only
to the extent the California legislature appropriates adequate funding
therefor.

In February 1987, the Governor of the State of California announced that
payments to Medi-Cal providers for certain services (not including hospital
acute inpatient services) would be decreased by ten percent through June 1987.
However, a federal district court issued a preliminary injunction preventing
application of any cuts until a trial on the merits can be held.  If the
injunction is deemed to have been granted improperly, the State of California
would be entitled to recapture the payment differential for the intended
reduction period.  It is not possible to predict at this time whether any
decreases will ultimately be implemented.

California enacted legislation in 1982 that authorizes private health plans and
insurers to contract directly with hospitals for services to beneficiaries on
negotiated terms.  Some insurers have introduced plans known as "preferred
provider organizations" ("PPOs"), which offer financial incentives for
subscribers who use only the hospitals which contract with the plan.  Under an
exclusive provider plan, which includes most health maintenance organizations
("HMOs"), private payors limit coverage to those services provided by selected
hospitals.  Discounts offered to HMOs and PPOs may result in payment to the
contracting hospital of less than actual cost and the volume of patients
directed to a hospital under an HMO or PPO contract may vary significantly from
projections.  Often, HMO or PPO contracts are enforceable for a stated term,
regardless of provider losses or of bankruptcy of the respective HMO or PPO.
It is expected that failure to execute and maintain such PPO and HMO contracts
would reduce a hospital's patient base or gross revenues.  Conversely,
participation may maintain or increase the patient base, but may result in
reduced payment and lower net income to the contracting hospitals.

These Debt Obligations may also be insured by the State of California pursuant
to an insurance program implemented by the Office of Statewide Health Planning
and Development for health facility construction loans.  If a default occurs on
insured Debt Obligations, the State Treasurer will issue debentures payable out
of a reserve fund established under the insurance program or will pay principal
and interest on an unaccelerated basis from unappropriated State funds.  At the
request of the Office of Statewide Health Planning and Development, Arthur D.
Little, Inc. prepared a study in December, 1983, to evaluate the adequacy of
the reserve fund established under the insurance program and based on certain
formulations and assumptions found the reserve fund substantially underfunded.
In September of 1986, Arthur D. Little, Inc. prepared an update of the study
and concluded that an additional 10% reserve be established for "multi-level"
facilities.  For the balance of the reserve fund, the update recommended
maintaining the current reserve calculation method.  In March of 1990, Arthur
D. Little, Inc. prepared a further review of the study and recommended that
separate reserves





                                      S-10

<PAGE>   294
continue to be established for "multi-level" facilities at a reserve level
consistent with those that would be required by an insurance company.


Certain California Municipal Securities in which the California Tax-Free Money
Market and California Intermediate Tax-Free Bond Funds may invest may be
obligations which are secured in whole or in part by a mortgage or deed of
trust on real property.  California has five principal statutory provisions
which limit the remedies of a creditor secured by a mortgage or deed of trust,
two of which limit the creditor's right to obtain a deficiency judgment.  One
of the limitations is based on the method of foreclosure and the other on the
type of debt secured.  Under the former, a deficiency judgment is barred when
the foreclosure is accomplished by means of a nonjudicial trustee's sale.
Under the latter, a deficiency judgment is barred when the foreclosed mortgage
or deed of trust secures certain purchase money obligations.  Another
California statute, commonly known as the "one form of action" rule, requires
the creditors secured by real property to exhaust their real property security
by foreclosure before bringing a personal action against the debtor.  The
fourth statutory provision limits any deficiency judgment obtained by a
creditor secured by real property following a judicial sale of such property to
the excess of the outstanding debt over the fair value of the property at the
time of the sale, thus preventing the creditor from obtaining a large
deficiency judgment against the debtor as the result of low bids at a judicial
sale.  The fifth statutory provision gives the debtor the right to redeem the
real property from any judicial foreclosure sale as to which a deficiency
judgment may be ordered against the debtor.


Upon the default of a mortgage or deed of trust with respect to California real
property, the creditor's nonjudicial foreclosure rights under the power of sale
contained in the mortgage or deed of trust are subject to the constraints
imposed by California law upon transfers of title to real property by private
power of sale.  During the three-month period beginning with the filing of a
formal notice of default, the debtor is entitled to reinstate the mortgage by
making any overdue payments.  Under standard loan servicing procedures, the
filing of the formal notice of default does not occur unless at least three
full monthly payments have become due and remain unpaid.  The power of sale is
exercised by posting and publishing a notice of sale for at least 20 days after
expiration of the three-month reinstatement period.  Therefore, the effective
minimum period for foreclosing on a home mortgage could be in excess of seven
months after the initial default.  Such time delays in collections could
disrupt the flow of revenues available to an issuer for the payment of debt
service on the outstanding obligations if such defaults occur with respect to a
substantial number of mortgages or deeds of trust securing an issuer's
obligations.

In addition, a court could find that there is sufficient involvement of the
issuer in the nonjudicial sale of property securing a mortgage for such private
sale to constitute "state action," and could hold that the
private-right-of-sale proceedings violate the due process requirements of the
Federal or State Constitutions, consequently preventing an issuer from using
the nonjudicial foreclosure remedy described above.


Certain California Municipal Securities in which the California Tax-Free Money
Market and California Intermediate Tax-Free Bond Funds may invest may be
obligations which finance the acquisition of single family home mortgages for
low and moderate income mortgagors.  These obligations may be payable solely
from revenues derived from the home mortgages, and are subject to the
California statutory limitations described above applicable to obligations
secured by real property.  Under California anti-deficiency legislation, there
is no personal recourse against a mortgagor of a single family residence
purchased with the loan secured by the mortgage, regardless of whether the
creditor chooses judicial or nonjudicial foreclosure.


Under California law, mortgage loans secured by single family owner-occupied
dwellings may be prepaid at any time.  Prepayment charges on such mortgage
loans may be imposed only with respect





                                      S-11

<PAGE>   295
to voluntary prepayments made during the first five years during the term of
the mortgage loan, and cannot in any event exceed six months' advance interest
on the amount prepaid in excess of 20% of the original amount of the mortgage
loan.  This limitation could affect the flow of revenues available to an issuer
for debt service on the outstanding debt obligations which financed such home
mortgages.

Because of the diverse nature of such laws and regulations and the
impossibility of either predicting in which specific California Municipal
Securities the Funds will invest from time to time or predicting the nature or
extent of future changes in existing laws or regulations or the future
enactment or adoption of additional laws or regulations, it is not presently
possible to determine the impact of such laws and regulations on the Municipal
Securities in which the Funds may invest and, therefore, on the units of the
Funds.


The General Financial Condition of the State of California.  The 1989-90 Fiscal
Year ended with revenues below estimates, so that the State's budget reserve
(the Special Fund for Economic Uncertainties or "SFEU") was fully depleted by
June 30, 1990. A recession began in mid-1990, which severely affected State
General Fund revenues, and increased expenditures above initial budget
appropriations due to greater health and welfare costs.  The State's budget
problems in recent years have also been caused by a structural imbalance in
that the largest General Fund Programs -- K-14 education, health, welfare and
corrections -- were increasing faster than the revenue base, driven by the
State's rapid population growth. These pressures are expected to continue as
population trends maintain strong demand for health and welfare services, as
the school age population continues to grow, and as the State's corrections
program responds to a "Three Strikes" law enacted in 1994, which requires
mandatory life prison terms for certain third-time felony offenders.


As a result of these factors and others, from the late 1980's until 1992-93,
the State had a period of budget imbalance. During this period, expenditures
exceeded revenues in four out of six years, and the State accumulated and
sustained a budget deficit in the SFEU approaching $2.8 billion at its peak at
June 30, 1993. Starting in the 1990-91 Fiscal Year and for each fiscal year
thereafter, each budget required multibillion dollar actions to bring projected
revenues and expenditures into balance. The Legislature and Governor agreed on
the following principal steps to produce Budget Acts in the years 1991-92 to
1993-94, including:


         -       significant cuts in health and welfare program expenditures;

         -       transfers of program responsibilities and funding from the
State to local governments referred to as "realignment"), coupled with some
reduction in mandates on local government;

         -       transfer of about $3.6 billion in local property tax revenues
from cities, counties, redevelopment agencies and some other districts to local
school districts, thereby reducing State funding for schools under Proposition
98;

         -       reduction in growth of support for higher education programs,
coupled with increases in student fees;

         -       revenue increases (particularly in the 1991-92 Fiscal Year
budget), most of which were of a short duration;

         -       increased reliance on aid from the federal government to
offset the costs of incarcerating, educating and providing health and welfare
services to illegal immigrants; and

         -       various one-time adjustments and accounting changes.





                                      S-12

<PAGE>   296

Despite these budget actions, as noted, the effects of the recession led to
large, unanticipated deficits in the budget reserve, the SFEU, as compared to
projected positive balances. By the 1993-94 Fiscal Year, the accumulated
deficit was so large that it was impractical to budget to retire it in one
year, so a two-year program was implemented, using the issuance of revenue
anticipation warrants to carry a portion of the deficit over the end of the
fiscal year. When the economy failed to recover sufficiently in 1993-94, a
second two-year plan was implemented in 1994-95.


Another consequence of the accumulated budget deficits, together-with other
factors such as disbursement of funds to local school districts "borrowed" from
future fiscal years and hence not shown in the annual budget, was to
significantly reduce the State's cash resources available to pay its ongoing
obligations. When the Legislature and the Governor failed to adopt a budget for
the 1992-93 Fiscal Year by July 1, 1992, which would have allowed the state to
carry out its normal annual cash flow borrowing to replenish its cash reserves,
the State Controller issued registered warrants to pay a variety of obligations
representing prior years' or continuing appropriations, and mandates from court
orders.  Available funds were used to make constitutionally-mandated payments,
such as debt service on bonds and warrants.  Between July 1 and September 4,
1992 the State Controller issued a total of approximately $3.8 billion of
registered warrants. After that date, all remaining outstanding registered
warrants (about $2.9 billion) were called for redemption from proceeds of the
issuance of 1992 Interim Notes after the budget was adopted.



In late spring of 1992, the State Controller issued revenue anticipation
warrants maturing in the following fiscal year in order to pay the State's
continuing obligations.  The State was forced to rely increasingly on external
debt markets to meet its cash needs, as a succession of notes and warrants were
issued in the period from June 1992 to July 1994, often needed to pay
previously maturing notes or warrants. These borrowings were used also in part
to spread out the repayment of the accumulated budget deficit over the end of a
fiscal year, as noted earlier.



The Governor's Budget Proposal for the 1994-95 Fiscal Year, as updated in May
and June 1994, recognized that the accumulated deficit could not be repaid in
one year, and proposed a two-year solution designed to eliminate the
accumulated budget deficit, estimated at about $1.8 billion at June 30, 1994,
by June 30, 1996.



The 1994-95 Budget Act, signed by the Governor on July 8, 1994, projected
General Fund revenues and transfers of $41.9 billion, $2.1 billion more than
actual revenues received in 1993-94, and expenditures of $40.9 billion, an
increase of $1.6 billion from the prior year. As a result of the improving
economy, the Department of Finance's final estimates for the fiscal year showed
revenues and transfers of $42.7 billion and expenditures of $42.0 billion,
reducing he accumulated budget deficit to about $600 million.



The principal features of the 1994-95 Budget Act were the following:



         1.      Receipt of additional federal aid of about $760 million for
costs of refugee assistance and costs of incarceration and medical care for
illegal immigrants. Only about $33 million of this amount was received, with
about another $98 million scheduled to be received in the 1995-96 Fiscal Year.



         2.      Reductions of approximately $1.1 billion in health and welfare
costs. Certain of these actions were blocked by legal challenges.



         3.      A General Fund increase of approximately $38 million in
support for the University of California and $65 million for California State
University, accompanied by student fee increases for both the University of
California and California State University.






                                      S-13

<PAGE>   297


         4.      Proposition 98 funding for K-14 schools was increased by $526
million from 1993-94 Fiscal Year levels, representing an increase for
enrollment growth and inflation.  Consistent with previous budget agreements,
Proposition 98 funding provided approximately $4,217 per student for K-12
schools, equal to the level in the prior three years.



         5.      Additional miscellaneous cuts ($500 million), fund transfers
($255 million), adjustment to prior years' legislation concerning property tax
shifts for local governments ($300 million).



The 1994-95 Budget Act contained no tax increases.  Under legislation enacted
for the 1993-94 Budget Act, the renters' tax credit was suspended for two years
(1993 and 1994).  A ballot proposition to permanently restore the renters' tax
credit after this year failed at the June 1994 election.  The Legislature
enacted a further one-year suspension of the renters' tax credit, for 1995,
saving about $390 million in the 1995-96 Fiscal Year.



The State's cash flow management plan for the 1994-95 Fiscal Year included the
issuance $4.0 billion of Revenue Anticipation Warrants, Series C and D (the
"RAWs") on July 26, 1994, to mature on April 25, 1996, as part of a two-year
plan to retire the accumulated State budget deficit.  To assure payment of the
RAWs, the Legislature enacted a backup mechanism which could result in
automatic expenditure cuts if projected revenues did not meet certain targets
(Section 12467 of the California Government Code, enacted by Chapter 135,
Statutes of 1994, the "Budget Adjustment Law").



The third and last step in the Budget Adjustment Law process occurred on
October 16, 1995, when the State Controller issued a report (the "October
Trigger Report") reviewing the estimated cash condition of the General Fund for
the 1995-96 Fiscal Year.  The State Controller estimated that the General Fund
would have at least $1.4 billion of internal cash resources on June 30, 1996
(i. e., external borrowing would not be needed on June 30, 1996). As a result
of this funding, certain provisions of the Budget Adjustment Law, which could
have ultimately led to automatic, across-the-board cuts in the General Fund
budget, will not have to be implemented.  Likewise, an earlier report issued on
November 15, 1994, avoided implementation of any automatic budget cuts in the
1994-95 fiscal year.)



The discussion below of the 1995-96 Fiscal Year budget is based on estimates
and projections of revenues and expenditures for the current fiscal year and
must not be construed as statements of fact.  These estimates and projections
are based upon various assumptions which may be affected by numerous factors,
including future economic conditions in the State and the nation, and there can
be no assurance that the estimates will be achieved.



Periodic reports on revenues and expenditures during the fiscal year are issued
by the Administration, the State Controller's Office and the Legislative
Analyst's Office.  The Department of Finance issues a monthly Bulletin which
reports the most recent revenue receipts, comparing them to Budget projections,
and reports on other current developments affecting the Budget.  The
Administration also formally updates its budget projections twice during each
fiscal year, generally in January and May.



With strengthening revenues and reduced caseload growth based on an improving
economy, the State entered the 1995-96 Fiscal Year budget negotiations with the
smallest nominal "budget gap" to be closed in many years.  Nonetheless, serious
policy differences between the Governor and Legislature prevented timely
enactment of the budget. The 1995-96 Budget Act was signed by the Governor on
August 3, 1995, 34 days after the start of the fiscal year.  The Budget Act
projected General Fund revenues and transfers of $44.1 billion, a 3.5 percent
increase from the prior year.  Expenditures were budgeted at $43.4 billion, a 4
percent increase.  The Department of Finance projected that, after repaying the
last of the carry over budget deficit, there would be a positive balance of $28
million in the budget reserve, the Special Fund for Economic Uncertainties, at
June 30,1996.  The Budget Act






                                      S-14

<PAGE>   298

also projected Special Fund revenues of $12.7 billion and appropriated Special
Fund expenditures of $13.0 billion.



The Governor's Budget for the 1996-97 Fiscal Year, released on January 10, 1996
(the Governor's Budget"), updated the current year projections, so that
revenues and transfers are estimated to be $45.0 billion, and expenditures to
be $44.2 billion.  The Special Fund for Economic Uncertainties is projected to
have a positive balance of about $50 million at June 30, 1996, and on that date
available internal borrowable resources (available cash, after payment of
obligations due) will be about $2.2 billion.  The Administration projects it
will issue up to $2.0 billion of revenue anticipation notes in April, 1996, to
mature June 30, 1996, to assist in cash flow management for the final two
months of the year, after repayment of the $4.0 billion RAW issue on April 25,
1996.



The following are the principal features of the 1995-96 Budget Act:



         1.      Proposition 98 funding for schools and community colleges was
originally budgeted to increase by about $ 1.0 billion (General Fund) and $ 1.2
billion total above revised 1994-95 levels.  Because of higher than projected
revenues in 1994-95, an additional $543 million ($91 per K-12 ADA) was
appropriated to the 1994-95 Proposition 98 entitlement.  A large part of this
is a block grant of about $54 per pupil for any one-time purpose.  For the
first time in several years, a full 2.7 percent cost of living allowance was
funded.  The budget compromise anticipates a settlement of the CTA v. Gould
litigation discussed above under "Voter Initiatives".  The Governor's Budget
indicates that, with revenues even higher than projected, Proposition 98
apportionments will exceed the amounts originally budgeted, reaching a level of
$4,500 per ADA.



         2.      Cuts in health and welfare costs totaling about $0.9 billion.
Some of these cuts (totaling about $500 million) require federal legislative or
administrative approval, which were still pending as of February, 1996.



         3.      A 3.5 percent increase in funding for the University of
California ($90 million General Fund) and the California State University
system ($24 million General Fund), with no increases in student fees.



         4.      The Budget, as updated by the 1996-97 Governor's Budget dated
January 10, 1996, assumed receipt of $494 million in new federal aid for
incarceration and health care costs of illegal immigrants, above commitments
already made by the federal government.



         5.      General Fund support for the Department of Corrections is
increased by about 8 percent over the prior year, reflecting estimates of
increased prison population, but funding is less than proposed in the 1995
Governor's Budget.



On January 10, 1996, the Governor released his proposed budget for the next
fiscal year (the "Governor's Budget").  The Governor requested total General
Fund appropriations of about $45.2 billion, based on projected revenues and
transfers of about $45.6 billion, which would leave a budget reserve in the
Special Fund for Economic Uncertainties at June 30, 1997 of about $400 million.
The Governor renewed a proposal, which had been rejected by the Legislature in
1995, for a 15 percent phased cut in individual and corporate tax rates over
three years (the budget proposal assumes this will be enacted, reducing
revenues in 1996-97 by about $600 million).  There was also a proposal to
restructure trial court funding in a way which would result in a $300 million
decrease in General Fund revenues.  The Governor requested legislation to make
permanent a moratorium on cost of living increases for welfare payments, and
suspension of a renters tax credit, which otherwise would go back into effect
in the 1996-97 Fiscal Year.  He further proposed additional cuts in certain
health and welfare programs, and assumed that cuts previously approved by the
Legislature will receive federal






                                      S-15

<PAGE>   299
approval.  The Governor's Budget proposes increases in funding for K-12 schools
under Proposition 98, for State higher education systems (with a second year of
no student fee increases), and for corrections.  The Governor's Budget projects
external cash flow borrowing of up to $3.2 billion, mature by June 30, 1997.



Additional Considerations.  With respect to Municipal Securities issued by the
State of California and its political subdivisions, as well as certain other
governmental issuers such as the Commonwealth of Puerto Rico, the Trust cannot
predict what legislation, if any, may be proposed in the California State
Legislature as regards the California State personal income tax status of
interest on such obligations, or which proposals, if any, might be enacted.
Such proposals, if enacted, might materially adversely affect the availability
of California Municipal Securities for investment by the Funds and the value of
the Funds' investments.  In such event, the Trustees would reevaluate the
investment objective and policies of the Funds and consider changes in its
investments structure or possible dissolution.

OPTIONS ON SECURITIES.  The Blue Chip Growth, Emerging Growth, Balanced, and
International Equity Funds may buy and sell options, and the Growth Equity,
Emerging Growth, Blue Chip Growth, Value Momentum, International Equity and
Balanced Funds may write CALL OPTIONS on a covered basis only.  A Fund will not
engage in option writing strategies for speculative purposes.


COVERED CALL WRITING.  The Growth Equity, Emerging Growth, Blue Chip Growth,
Balanced, International Equity and Value Momentum Funds may write covered call
options from time to time on such portion of its assets, without limit, as the
Advisor determines is appropriate in seeking to obtain each Fund's investment
objective.  A call option gives the purchaser of such option the right to buy,
and the writer, in this case the Fund, has the obligation to sell the
underlying security at the exercise price during the option period.  The
advantage to the Fund of writing covered calls is that the Fund receives a
premium which is additional income. However, if the value of the security
rises, the Fund may not fully participate in the market appreciation.



During the option period, a covered call option writer may be assigned an
exercise notice by the broker/dealer through whom such call option was sold,
which requires the writer to deliver the underlying security against payment of
the exercise price.  This obligation is terminated upon the expiration of the
option period or at such earlier time in which the writer effects a closing
purchase transaction.  A closing purchase transaction is one in which a Fund
when obligated as a writer of an option, terminates its obligation by
purchasing an option of the same series as the option previously written.  A
closing purchase transaction cannot be effected with respect to an option once
the option writer has received an exercise notice for such option.


Closing purchase transactions will ordinarily be effected to realize a profit
on an outstanding call option, to prevent an underlying security from being
called, to permit the sale of the underlying security, or to enable the Fund to
write another call option on the underlying security with either a different
exercise price or expiration date or both.  The Fund may realize a net gain or
loss from a closing purchase transaction, depending upon whether the net amount
of the original premium received on the call option is more or less than the
cost of effecting the closing purchase transaction.  Any loss incurred in a
closing purchase transaction may be partially or entirely offset by the premium
received from a sale of a different call option on the same underlying
security.  Such a loss may also be wholly or partially offset by unrealized
appreciation in the market value of the underlying security.  Conversely, a
gain resulting from a closing purchase transaction could be offset in whole or
in part by a decline in the market value of the underlying security.

If a call option expires unexercised, the Fund will realize a short term
capital gain in the amount of the premium on the option, less the commission
paid.  Such a gain, however, may be offset by





                                      S-16

<PAGE>   300
depreciation in the market value of the underlying security during the option
period. If a call option is exercised, the Fund will realize a gain or loss
from the sale of the underlying security equal to the difference between the
cost of the underlying security, and the proceeds of the sale of the security
plus the amount of the premium on the option, less the commission paid.

The market value of a call option generally reflects the market price of an
underlying security.  Other principal factors affecting market value include
supply and demand, interest rates, the price volatility of the underlying
security and the time remaining until the expiration date.  The Fund will write
call options only on a covered basis, which means that the Fund will own the
underlying security subject to a call option at all times during the option
period or will own the right to acquire the underlying security at a price
equal to or below the option's strike price.  Unless a closing purchase
transaction is effected the Fund would be required to continue to hold a
security which it might otherwise wish to sell, or deliver a security it would
want to hold.  Options written by the Fund will normally have expiration dates
between one and nine months from the date written.  The exercise price of a
call option may be below, equal to or above the current market value of the
underlying security at the time the option is written.

         Purchasing Call Options . The Blue Chip Growth, Balanced, Emerging and
International Equity Funds may purchase call options to hedge against an
increase in the price of securities that the Fund wants ultimately to buy. Such
hedge protection is provided during the life of the call option since the Fund,
as holder of the call option, is able to buy the underlying security at the
exercise price regardless of any increase in the underlying security's market
price. In order for a call option to be profitable, the market price of the
underlying security must rise sufficiently above the exercise price to cover the
premium and transaction costs. These costs will reduce any profit the Fund might
have realized had it bought the underlying security at the time it purchased the
call option.

         Purchasing Put Options.  The Blue Chip Growth, Balanced, Emerging and
International Equity Growth Funds may purchase put options to protect its
portfolio holdings in an underlying security against a decline in market value.
Such hedge protection is provided during the life of the put option since the
Fund, as holder of the put option, is able to sell the underlying security at
the put exercise price regardless of any decline in the underlying security's
market price.  For a put option to be profitable, the market price of the
underlying security must decline sufficiently below the exercise price to cover
the premium and transaction costs.  By using put options in this manner, a Fund
will reduce any profit it might otherwise have realized from appreciation of
the underlying security by the premium paid for the put option and by
transaction costs.

The Growth Equity Fund, the Value Momentum Fund, Emerging Growth, Blue Chip
Growth, Balanced Fund and the International Equity Fund may engage in OPTIONS
ON STOCK INDICES. A stock index assigns relative values to the common stocks
included in the index with the index fluctuating with changes in the market
values of the underlying common stock.

Options on stock indices are similar to options on stocks but have different
delivery requirements.  Stock options provide the right to take or make
delivery of the underlying stock at a specified price.  A stock index option
gives the holder the right to receive a cash "exercise settlement amount" equal
to (i) the amount by which the fixed exercise price of the option exceeds (in
the case of a put) or is less than (in the case of a call) the closing value of
the underlying index on the date of exercise, multiplied by (ii) a fixed "index
multiplier."  Receipt of this cash amount will depend upon the closing level of
the stock index upon which the option is based being greater than (in the case
of a call) or less than (in the case of a put) the exercise price of the
option.  The amount of cash received will be equal to such difference between
the closing price of the index and exercise price of the option expressed in
dollars times a specified multiple.  The writer of the option is obligated, in
return for the premium received, to





                                      S-17

<PAGE>   301
make delivery of this amount.  Gain or loss to a Fund on transactions in stock
index options will depend on price movements in the stock market generally (or
in a particular industry or segment of the market) rather than price movements
of individual securities.

As with stock options, a Fund may offset its position in stock index options
prior to expiration by entering into a closing transaction on an Exchange or it
may let the option expire unexercised.

A stock index fluctuates with changes in the market values of the stock so
included.  Some stock index options are based on a broad market index, such as
the Standard & Poor's 500 or the New York Stock Exchange Composite Index, or a
narrower market index such as the Standard & Poor's 100.  Indices are also
based on an industry or market segment such as the AMEX Oil and Gas Index or
the Computer and Business Equipment Index.  Options on stock indices are
currently traded on the following Exchanges among others:  The Chicago Board
Options Exchange, New York Stock Exchange, American Stock Exchange and London
Stock Exchange.

A Fund's ability to hedge effectively all or a portion of its securities
through transactions in options on stock indices depends on the degree to which
price movements in the underlying index correlate with price movements in the
Fund's portfolio securities. Since a Fund's portfolio will not duplicate the
components of an index, the correlation will not be exact. Consequently, a Fund
bears the risk that the prices of the securities being hedged will not move in
the same amount as the hedging instrument.  It is also possible that there may
be a negative correlation between the index or other securities underlying the
hedging instrument and the hedged securities which would result in a loss on
both such securities and the hedging instrument.

Positions in stock index options may be closed out only on an exchange which
provides a secondary market. There can be no assurance that a liquid secondary
market will exist for any particular stock index option. Thus, it may not be
possible to close such an option. The inability to close options positions
could have an adverse impact on a Fund's ability to hedge effectively its
securities.  A Fund will enter into an option position only if there appears to
be a liquid secondary market for such options.

A Fund will not engage in transactions in options on stock indices for
speculative purposes but only to protect appreciation attained, to offset
capital losses and to take advantage of the liquidity available in the option
markets.  The aggregate premium paid on all options on stock indices will not
exceed 20% of a Fund's total assets.


         Risk Factors in Options Transactions . The successful use of options
strategies depends on the ability of the investment advisor or, where
applicable, SubAdvisor to forecast interest rate and market movements correctly.


         When it purchases an option, a Fund runs the risk that it will lose
its entire investment in the option in a relatively short period of time,
unless the Fund exercises the option or enters into a closing sale transaction
with respect to the option during the life of the option.  If the price of the
underlying security does not rise (in the case of a call) or fall (in the case
of a put) to an extent sufficient to cover the option premium and transaction
costs, a Fund will lose part or all of its investment in the option.  This
contrasts with an investment by a Fund in the underlying securities, since the
Fund may continue to hold its investment in those securities notwithstanding
the lack of a change in price of those securities.


         The effective use of options also depends on a Fund's ability to
terminate option positions at times when its investment advisor or, where
applicable, SubAdvisor deems it desirable to do so.  Although a Fund will take
an option position only if its investment advisor or, where applicable,






                                      S-18

<PAGE>   302

SubAdvisor believes there is a liquid secondary market for the option, there is
no assurance that a Fund will be able to effect closing transactions at any
particular time or at an acceptable price.


         If a secondary trading market in options were to become unavailable, a
Fund could no longer engage in closing transactions.  Lack of investor interest
might adversely affect the liquidity of the market for particular options or
series of options.  A marketplace may discontinue trading of a particular
option or options generally.  In addition, a market could become temporarily
unavailable if unusual events, such as volume in excess of trading or clearing
capability, were to interrupt normal market operations.  A marketplace may at
times find it necessary to impose restrictions on particular types of options
transactions, which may limit a Fund's ability to realize its profits or limit
its losses.

         Disruptions in the markets for the securities underlying options
purchased or sold by a Fund could result in losses on the options.  If trading
is interrupted in an underlying security, the trading of options on that
security is normally halted as well.  As a result, a Fund as purchaser or
writer of an option will be unable to close out its positions until options
trading resumes, and it may be faced with losses if trading in the security
reopens at a substantially different price.  In addition, the Options Clearing
Corporation (OCC) or other options markets, such as the London Options Clearing
House, may impose exercise restrictions.  If a prohibition on exercise is
imposed at the time when trading in the option has also been halted, a Fund as
purchaser or writer of an option will be locked into its position until one of
the two restrictions has been lifted.  If a prohibition on exercise remains in
effect until an option owned by a Fund has expired, the Fund could lose the
entire value of its option.

         Futures Contracts on Securities and Related Options

         Futures Contracts on Securities . A Fund will enter into futures
contracts on securities only when, in compliance with the SEC's requirements,
cash or equivalents equal in value to the securities' value (less any applicable
margin deposits) have been deposited in a segregated account of the Fund's
custodian.

         A futures contract sale creates an obligation by the seller to deliver
the type of instrument called for in the contract in a specified delivery month
for a stated price.  A futures contract purchase creates an obligation by the
purchaser to take delivery of the type of instrument called for in the contract
in a specified delivery month at a stated price.  The specific instruments
delivered or taken at settlement date are not determined until on or near that
date.  The determination is made in accordance with the rules of the exchanges
on which the futures contract was made.  Futures contracts are traded in the
United States only on commodity exchange or boards of trade, known as "contract
markets," approved for such trading by the Commodity Futures Trading Commission
(CFTC), and must be executed through a futures commission merchant or brokerage
firm which is a member of the relevant contract market.

         Although futures contracts by their terms call for actual delivery or
acceptance of securities, the contracts usually are closed out before the
settlement date without the making or taking of delivery.  Closing out a
futures contract sale is effected by purchasing a futures contract for the same
aggregate amount of the specific type of financial instrument with the same
delivery date.  If the price of the initial sale of the futures contract
exceeds the price of the offsetting purchase, the seller is paid the difference
and realizes a gain.  Similarly, the closing out of a futures contract purchase
is effected by the purchaser's entering into a futures contract sale.  If the
offsetting sale price exceeds the purchase price, the purchaser realizes a
gain, and if the purchase price exceeds the offsetting sale price, the
purchaser realizes a loss.

         Unlike when a Fund purchases or sells a security, no price is paid or
received by the Fund upon the purchase or sale of a futures contract, although
the Fund is required to deposit with its





                                      S-19

<PAGE>   303
custodian in a segregated account in the name of the futures broker an amount
of cash and/or U.S. Government securities.  This amount is known as "initial
margin."  The nature of initial margin in futures transactions is different
from that of margin in security transactions in that futures contract margin
does not involve the borrowing of funds by the Fund to finance the
transactions.  Rather, initial margin is in the nature of a performance bond or
good faith deposit on the contract that is returned to the Fund upon
termination of the futures contract, assuming all contractual obligations have
been satisfied.  Futures contracts also involve brokerage costs.

         Subsequent payments, called "variation margin," to and from the broker
(or the custodian) are made on a daily basis as the price of the underlying
security fluctuates, making the long and short positions in the futures
contract more or less valuable, a process known as "marking to market."

         A Fund may elect to close some or all of its futures positions at any
time prior to their expiration.  The purpose of making such a move would be to
reduce or eliminate the hedge position then currently held by the Fund.  A Fund
may close its positions by taking opposite positions which will operate to
terminate the Fund's position in the futures contracts.  Final determinations
of variation margin are then made, additional cash is required to be paid by or
released to the Fund, and the Fund realizes a loss or a gain.  Such closing
transactions involve additional commission costs.

         Options on Securities' Futures Contracts . A Fund will enter into
written options on securities' futures contracts only when, in compliance with
the SEC's requirements, cash or equivalents equal in value to the securities'
value (less any applicable margin deposits) have been deposited in a segregated
account of the Fund's custodian. A Fund may purchase and write call and put
options on the futures contracts it may buy or sell and enter into closing
transactions with respect to such options to terminate existing positions. A
Fund may use such options on futures contracts in lieu of writing options
directly on the underlying securities or purchasing and selling the underlying
futures contracts. Such options generally operate in the same manner as options
purchased or written directly on the underlying investments.

         As with options on securities, the holder or writer of an option may
terminate his position by selling or purchasing an offsetting option.  There is
no guarantee that such closing transactions can be effected.

         A Fund will be required to deposit initial margin and maintenance
margin with respect to put and call options on futures contracts written by it
pursuant to brokers' requirements similar to those described above.

         Aggregate initial margin deposits for futures contracts (including
futures contracts on securities, indices and currency) and premiums paid for
related options, may not exceed 5% of a Fund's total assets.


         Risk of Transactions in Securities' Futures Contracts and Related
Options.  Successful use of securities' futures contracts by a Fund is subject
to the ability of its investment advisor or, where applicable, SubAdvisor to
predict correctly movements in the direction of interest rates and other
factors affecting securities markets.


         Compared to the purchase or sale of futures contracts, the purchase of
call or put options on futures contracts involves less risk to a Fund because
the maximum amount at risk is the premium paid for the options (plus
transaction costs).  However, there may be circumstances when the purchase of a
call or put option on a futures contract would result in a loss to a Fund when
the purchase or sale of a futures contract would not, such as when there is no
movement in the price of





                                      S-20

<PAGE>   304
the hedged investments.  The writing of an option on a futures contract
involves risks similar to those risks relating to the sale of futures
contracts.

         There is no assurance that higher than anticipated trading activity or
other unforeseen events will not, at times, render certain market clearing
facilities inadequate, and thereby result in the institution by exchanges of
special procedures which may interfere with the timely execution of customer
orders.

         To reduce or eliminate a hedge position held by a Fund, the Fund may
seek to close out a position.  The ability to establish and close out positions
will be subject to the development and maintenance of a liquid secondary
market.  It is not certain that this market will develop or continue to exist
for a particular futures contract.  Reasons for the absence of a liquid
secondary market on an exchange include the following:  (i) there may be
insufficient trading interest in certain contracts or options; (ii)
restrictions may be imposed by an exchange on opening transactions or closing
transactions or both; (iii) trading halts, suspensions or other restrictions
may be imposed with respect to particular classes or series of contracts or
options, or underlying securities; (iv) unusual or unforeseen circumstances may
interrupt normal operations on an exchange; (v) the facilities of an exchange
or a clearing corporation may not at all times be adequate to handle current
trading volume; or (vi) one or more exchanges could, for economic or other
reasons, decide or be compelled at some future date to discontinue the trading
of contracts or options (or a particular class or series of contracts or
options), in which event the secondary market on that exchange (or in the class
or series of contracts or options) would cease to exist, although outstanding
contracts or options on the exchange that had been issued by a clearing
corporation as a result of trades on that exchange would continue to be
exercisable in accordance with their terms.

         Futures Contracts on Indices and Related Options

         Index Futures Contracts . A Fund may enter into stock index futures
contracts, debt index futures contracts, or other index futures contracts
appropriate to its objective, and may purchase and sell options on such index
futures contracts. A Fund will not enter into any index futures contract for the
purpose of speculation, and will only enter into contracts traded on securities
exchanges with standardized maturity dates.

         An index futures contract is a bilateral agreement pursuant to which
two parties agree to take or make delivery of an amount of cash equal to a
specified dollar amount times the difference between the index value at the
close of trading of the contracts and the price at which the futures contract
is originally struck.  No physical delivery of the securities comprising the
index is made; generally contracts are closed out prior to the expiration date
of the contract.  No price is paid upon entering into index futures contracts.
When a Fund purchases or sells an index futures contract, it is required to
make an initial margin deposit in the name of the futures broker and to make
variation margin deposits as the value of the contract fluctuates, similar to
the deposits made with respect to futures contracts on securities.  Positions
in index futures contracts may be closed only on an exchange or board of trade
providing a secondary market for such index futures contracts.  The value of
the contract usually will vary in direct proportion to the total face value.

         A Fund's ability to effectively utilize index futures contracts
depends on several factors.  First, it is possible that there will not be a
perfect price correlation between the index futures contracts and their
underlying index.  Second, it is possible that a lack of liquidity for index
futures contracts could exist in the secondary market, resulting in the Fund's
inability to close a futures position prior to its maturity date.  Third, the
purchase of an index futures contract involves the risk that the Fund could
lose more than the original margin deposit required to initiate a futures
transaction.  In order to avoid leveraging and related risks, when a Fund
purchases an index futures contract, it will collateralize its





                                      S-21

<PAGE>   305
position by depositing an amount of cash or cash equivalents, equal to the
market value of the index futures positions held, less margin deposits, in a
segregated account with the Fund's custodian.  Collateral equal to the current
market value of the index futures position will be maintained on a daily basis.

         The extent to which a Fund may enter into transactions involving index
futures contracts may be limited by the Internal Revenue Code's requirements
for qualification as a regulated investment company and the Funds' intention to
qualify as such.

         Options on Index Futures Contracts.  Options on index futures
contracts are similar to options on securities except that options on index
futures contracts gives the purchaser the right, in return for the premium
paid, to assume a position in an index futures contract (a long position if the
option is a call and a short position if the option is a put), at a specified
exercise price at any time during the period of the option.  Upon exercise of
the option, the delivery of the futures position by the writer of the option to
the holder of the option will be accompanied by delivery of the accumulated
balance in the writer's futures margin account which represents the amount by
which the market price of the index futures contract, at exercise, exceeds (in
the case of a call) or is less than (in the case of a put) the exercise price
of the option on the index futures contract.  If an option is exercised on the
last trading day prior to the expiration date of the option, the settlement
will be made entirely in cash equal to the difference between the exercise
price of the option and the closing level of the index on which the future is
based on the expiration date.  Purchasers of options who fail to exercise their
options prior to the exercise date suffer a loss of the premium paid.

U.S. DOLLAR DENOMINATED OBLIGATIONS OF SECURITIES OF FOREIGN ISSUERS.  Certain
of the Funds may invest in U.S. DOLLAR DENOMINATED OBLIGATIONS OF SECURITIES OF
FOREIGN ISSUERS.  Permissible investments may consist of obligations of foreign
branches of U.S. banks and of foreign banks, including European Certificates of
Deposit, European Time Deposits, Canadian Time Deposits and Yankee Certificates
of Deposits, and investments in Canadian Commercial Paper, foreign securities
and Europaper.  In addition, the Growth Equity, Emerging Growth, Blue Chip
Growth, Government Securities, Convertible Securities, Value Momentum,
International Equity and Balanced Funds may invest in American Depositary
Receipts.  These instruments may subject the Fund to investment risks that
differ in some respects from those related to investments in obligations of
U.S. domestic issuers.  Such risks include future adverse political and
economic developments, the possible imposition of withholding taxes on interest
or other income, possible seizure, nationalization, or expropriation of foreign
deposits, the possible establishment of exchange controls or taxation at the
source, greater fluctuations in value due to changes in exchange rates, or the
adoption of other foreign governmental restrictions which might adversely
affect the payment of principal and interest on such obligations.  Such
investments may also entail higher custodial fees and sales commissions than
domestic investments.  Foreign issuers of securities or obligations are often
subject to accounting treatment and engage in business practices different from
those respecting domestic issuers of similar securities or obligations.
Foreign branches of U.S. banks and foreign banks may be subject to less
stringent reserve requirements than those applicable to domestic branches of
U.S. banks.

FOREIGN CURRENCY TRANSACTIONS.  Under normal market conditions, the
International Equity Fund may engage in foreign currency exchange transactions
to protect against uncertainty in the level of future exchange rates.  The
International Equity Fund expects to engage in foreign currency exchange
transactions in connection with the purchase and sale of portfolio securities
("transaction hedging"), and to protect the value of specific portfolio
positions ("position hedging").  The Fund may purchase or sell a foreign
currency on a spot (or cash) basis at the prevailing spot rate in connection
with the settlement of transactions in portfolio securities denominated in that
foreign currency, and may also enter into contracts to purchase or sell foreign
currencies at a future date ("forward contracts") and





                                      S-22

<PAGE>   306
purchase or sell foreign currency futures contracts ("futures contracts").  The
Fund may also purchase domestic and foreign exchange-listed and
over-the-counter call and put options on foreign currencies and futures
contracts.  Hedging transactions involve costs and may result in losses, and
the Fund's ability to engage in hedging and related options transactions may be
limited by tax considerations.

TRANSACTION HEDGING.  When it engages in transaction hedging, the International
Equity Fund enters into foreign currency transactions with respect to specific
receivables or payables of the International Equity Fund generally arising in
connection with the purchase or sale of its portfolio securities.  The
International Equity Fund will engage in transaction hedging when it desires to
"lock in" the U.S. dollar price of a security it has agreed to purchase or
sell, or the U.S. dollar equivalent of a dividend or interest payment in a
foreign currency.  By transaction hedging, the Fund will attempt to protect
itself against a possible loss resulting from an adverse change in the
relationship between the U.S. dollar and the applicable foreign currency during
the period between the date on which the security is purchased or sold, or on
which the dividend or interest payment is declared, and the date on which such
payments are made or received.


         Although there is no current intention to do so, the International
Equity Fund reserves the right to purchase and sell foreign currency futures
contracts which are traded in the United States and are subject to regulation
by the CFTC.


         For transaction hedging purposes the International Equity Fund may
also purchase exchange-listed call and put options on foreign currency futures
contracts and on foreign currencies.  A put option on a futures contract gives
the International Equity Fund the right to assume a short position in the
futures contract until expiration of the option.  A put option on currency
gives the International Equity Fund the right to sell a currency at an exercise
price until the expiration of the option.  A call option on a futures contract
gives the Fund the right to assume a long position in the futures contract
until the expiration of the option.  A call option on currency gives the Fund
the right to purchase a currency at the exercise price until the expiration of
the option.


POSITION HEDGING.  When it engages in position hedging, the International
Equity Fund enters into foreign currency exchange transactions to protect
against a decline in the values of the foreign currencies in which its
portfolios securities are denominated (or an increase in the value of currency
for securities which the SubAdvisor expects to purchase, when the Fund holds
cash or short- term investments).  In connection with the position hedging, the
Fund may purchase or sell foreign currency forward contracts or foreign
currency on a spot basis.


         The precise matching of the amounts of foreign currency exchange
transactions and the value of the portfolio securities involved will not
generally be possible since the future value of such securities in foreign
currencies will change as a consequence of market movements in the value of
those securities between the dates the currency exchange transactions are
entered into and the dates they mature.

         It is impossible to forecast with precision the market value of
portfolio securities at the expiration or maturity of a forward contract or
futures contract.  Accordingly, it may be necessary for the International
Equity Fund to purchase additional foreign currency on the spot market (and
bear the expense of such purchase) if the market value of the security or
securities being hedged is less than the amount of foreign currency the Fund is
obligated to deliver and if a decision is made to sell the security or
securities and make delivery of the foreign currency.  Conversely, it may be
necessary to sell on the spot market some of the foreign currency received upon
the sale of the portfolio security or securities if the market value of such
security or securities exceeds the amount of foreign currency the International
Equity Fund is obligated to deliver.





                                      S-23

<PAGE>   307

         Transaction and position hedging do not eliminate fluctuations in the
underlying prices of the securities which the International Equity Fund owns or
expects to purchase or sell.  They simply establish a rate of exchange which
one can achieve at some future point in time.  Additionally, although these
techniques tend to minimize the risk of loss due to a decline in the value of
the hedged currency, they tend to limit any potential gain which might result
from the increase in the value of such currency.


CURRENCY FORWARD AND FUTURES CONTRACTS.  A forward contract involves an
obligation to purchase or sell a specific currency at a future date, which may
be any fixed number of days from the date of the contract as agreed by the
parties, at a price set at the time of the contract.  In the case of a
cancelable forward contract, the holder has the unilateral right to cancel the
contract at maturity by paying a specified fee.  Forward contracts are trades
in the interbank markets conducted directly between currency traders (usually
large commercial banks) and their customers.  A forward contract generally has
no deposit requirement, and no commissions are charged at any stage for trades.


         A futures contract is a standardized contract for the future delivery
of a specified amount of a foreign currency at a future date at a price set at
the time of the contract.  Futures contracts are designed by and traded on
exchanges.  The Fund would enter into futures contracts solely for hedging or
other appropriate risk management purposes as defined in the controlling
regulations.

         Forward contracts differ from futures contracts in certain respects.
For example, the maturity date of a forward contract may be any fixed number of
days from the date of the contract agreed upon by the parties, rather than a
predetermined date in a given month.  Forward contracts may be in any amounts
agreed upon by the parties rather than predetermined amounts.  Also, forward
contracts are traded directly between currency traders so that no intermediary
is required.  A forward contract generally requires no margin or other deposit.

         At the maturity of a forward or futures contract, the Fund may either
accept or make delivery of the currency specified in the contract, or at or
prior to maturity enter into a closing transaction involving the purchase or
sale of an offsetting contract.  Closing transactions with respect to forward
contracts are usually effected with the currency trader who is a party to the
original forward contract.  Closing transactions with respect to futures
contracts are effected on a commodities exchange; a clearing corporation
associated with the exchange assumes responsibility for closing out such
contracts.

         Positions in the futures contracts may be closed out only on an
exchange or board of trade which provides a secondary market in such contracts.
Although the Fund intends to purchase or sell futures contracts only on
exchanges or boards of trade where there appears to be an active secondary
market, there is no assurance that a secondary market on an exchange or board
of trade will exist for any particular contract or at any particular time.  In
such event, it may not be possible to close a futures position and, in the
event of adverse price movements, the Fund would continue to be required to
make daily cash payments of variation margin, as described below.

GENERAL CHARACTERISTICS OF CURRENCY FUTURES CONTRACTS.  When the Fund purchases
or sells a futures contract, it is required to deposit with its custodian an
amount of cash or U.S. Treasury bills up to 5% of the amount of the futures
contract.  This amount is known as "initial margin."  The nature of initial
margin is different from that of margin in security transactions in that it
does not involve borrowing money to finance transactions.  Rather, initial
margin is similar to a performance bond or good faith deposit that is returned
to the International Equity Fund upon termination of the contract, assuming the
Fund satisfies its contractual obligation.





                                      S-24

<PAGE>   308
         Subsequent payments to and from the broker occur on a daily basis in a
process known as "marking to market."  These payments are called "variation
margin," and are made as the value of the underlying futures contract
fluctuates.  For example, when the Fund sells a futures contract and the price
of the underlying currency rises above the delivery price, the International
Equity Fund's position declines in value.  The Fund then pays a broker a
variation margin payment equal to the difference between the delivery price of
the futures contract and the market price of the currency underlying the
futures contract.  Conversely, if the price of the underlying currency falls
below the delivery price of the contract, the Fund's futures position increases
in value.  The broker then must make a variation margin payment equal to the
difference between the delivery price of the futures contract and the market
price of the currency underlying the futures contract.

         When the International Equity Fund terminates a position in a futures
contract, a final determination of variation margin is made, additional cash is
paid by or to the International Equity Fund, and the International Equity Fund
realizes a loss or gain.  Such closing transactions involve additional
commission costs.


FOREIGN CURRENCY OPTIONS.  Options on foreign currencies operate similarly to
options on securities, and are traded primarily in the over-the-counter market,
although options on foreign currencies have recently been listed on several
exchanges.  Such options will be purchased or written only when the Fund's
SubAdvisor believes that a liquid secondary market exists for such options.
There can be no assurance that a liquid secondary market will exist for a
particular option at any specific time.  Options on foreign currencies are
affected by all of those factors which influence foreign exchange rates and
investments generally.


         The value of a foreign currency option is dependent upon the value of
the foreign currency and the U.S. dollar, and may have no relationship to the
investment merits of a foreign security.  Because foreign currency transactions
occurring in the interbank market involve substantially larger amounts than
those that may be involved in the use of foreign currency options, investors
may be disadvantaged by having to deal in an odd lot market (generally
consisting of transactions of less than $1 million) for the underlying foreign
currencies at prices that are less favorable than for round lots.


         There is no systematic reporting of last sale information for foreign
currencies, and there is no regulatory requirement that quotations available
through dealer or other market sources be firm or revised on a timely basis.
Available quotation information is generally representative of very large
transactions in the interbank market, and thus may not reflect relatively
smaller transactions (less than $1 million), where rates may be less favorable.
The interbank market in foreign currencies is a global, around-the-clock
market.


FOREIGN CURRENCY CONVERSION.  Although foreign exchange dealers do not charge a
fee for currency conversion, they do realize a profit based on the difference
(the "spread") between prices at which they are buying and selling various
currencies.  Thus, a dealer may offer to sell a foreign currency to an
International Equity Fund at one rate, while offering a lesser rate of exchange
should the Fund desire to resell that currency to the dealer.

WHEN-ISSUED SECURITIES.  These securities involve the purchase of debt
obligations on a when-issued basis, in which case delivery and payment normally
take place within 45 days after the date of commitment to purchase.  The Funds
will only make commitments to purchase obligations on a when-issued basis with
the intention of actually acquiring the securities, but may sell them before
the settlement date.  The when-issued securities are subject to market
fluctuation, and no interest accrues on the security to the purchaser during
this period.  The payment obligation and the interest rate that





                                      S-25

<PAGE>   309
will be received on the securities are each fixed at the time the purchaser
enters into the commitment.  Purchasing obligations on a when-issued basis is a
form of leveraging, and can involve a risk that the yields available in the
market when the delivery takes place may actually be higher than those obtained
in the transaction itself.  In that case there could be an unrealized loss at
the time of delivery.


Segregated accounts will be established with the Custodian, and the Funds will
maintain liquid, high grade assets in an amount at least equal in value to the
Funds' commitments to purchase when-issued securities.



RESTRICTED SECURITIES.  RESTRICTED SECURITIES are securities that may
not be sold to the public without registration under the Securities Act of 1933
(the "1933 Act") absent an exemption from registration.  All of the Funds may
invest in restricted securities.  The Advisor may invest up to 25% of the total
assets of a Fund in restricted securities. In purchasing such restricted
securities, the Advisor intends to rely upon the exemptions from registration
provided by Section 4(2) and Rule 144A promulgated under the 1933 Act.
Restricted securities may be determined by the Advisor to be liquid
based on guidelines established and periodically reviewed by the Board of
Trustees.  Under these guidelines, the Advisor will consider the frequency of
trades and quotes for the security, the number of dealers in, and potential
purchasers for, the securities, dealer undertakings to make a market in the
security, and the nature of the security and of the marketplace trades. 


LENDING OF PORTFOLIO SECURITIES.  All of the Funds except the California
Intermediate Tax-Free Bond Fund may LEND SECURITIES pursuant to agreements
requiring that the loans be continuously secured by cash, securities of the
U.S. government or its agencies, or any combination of cash and such
securities, as collateral equal to 100% of the market value at all times of the
loaned securities.  Such loans will not be made if, as a result, the aggregate
amount of all outstanding securities loans for a Fund exceed one-third of the
value of its total assets taken at fair market value.  A Fund will continue to
receive interest on the loaned securities while simultaneously earning interest
on the investment of the cash collateral in U.S. government securities.
However, a Fund will normally pay lending fees to such broker-dealers and
related expenses from the interest earned on invested collateral.  There may be
risks of delay in receiving additional collateral or risks of delay in recovery
of the securities or even loss of rights in the collateral should the borrower
of the securities fail financially.  However, loans are made only to borrowers
deemed by the Advisor to be of good standing and when, in the judgment of the
Advisor, the consideration which can be earned currently from such securities
loans justifies the attendant risk.  Any loan may be terminated by either party
upon reasonable notice to the other party.  The Funds may use the Distributor
or a broker/dealer affiliate of the Advisor as a broker in these transactions.


STANDARD & POOR'S DEPOSITARY RECEIPTS ("SPDRS").  SPDRs are interests in a unit
investment trust ("UIT") that may be obtained from the UIT or purchased in the
secondary market as SPDRs are listed on the American Stock Exchange.

The UIT will issue SPDRs in aggregations of 50,000 known as "Creation Units" in
exchange for a "Portfolio Deposit" consisting of (a) a portfolio of securities
substantially similar to the component securities ("Index Securities") of the
Standard & Poor's 500 Composite Stock Price Index (the "S&P Index"), (b) a cash
payment equal to a pro rata portion of the dividends accrued on the UIT's
portfolio securities since the last dividend payment by the UIT, net of
expenses and liabilities, and (c) a cash





                                      S-26

<PAGE>   310
payment or credit ("Balancing Amount") designed to equalize the net asset value
of the S&P Index and the net asset value of a Portfolio Deposit.

SPDRs are not individually redeemable, except upon termination of the UIT.  To
redeem, the Portfolio must accumulate enough SPDRs to reconstitute a Creation
Unit.  The liquidity of small holdings of SPDRs, therefore, will depend upon
the existence of a secondary market.  Upon redemption of a Creation Unit, the
Portfolio will receive Index Securities and cash identical to the Portfolio
Deposit required of an investor wishing to purchase a Creation Unit that day.

The price of SPDRs is derived and based upon the securities held by the UIT.
Accordingly, the level of risk involved in the purchase or sale of a SPDR is
similar to the risk involved in the purchase or sale of traditional common
stock, with the exception that the pricing mechanism for SPDRs is based on a
basket of stocks.  Disruptions in the markets for the securities underlying
SPDRs purchased or sold by the Portfolio could result in losses on SPDRs.
Trading in SPDRs involves risks similar to those risks, described above under
"Options," involved in the writing of options on securities.


HIGH YIELD SECURITIES



The Convertible Securities Fund may invest in lower rated securities.  Fixed
income securities are subject to the risk of an issuer's ability to meet
principal and interest payments on the obligation (credit risk), and may also
be subject to price volatility due to such factors as interest rate
sensitivity, market perception of the creditworthiness of the issuer and
general market liquidity (market risk).  Lower rated or unrated (i.e., high
yield) securities are more likely to react to developments affecting market and
credit risk than are more highly rated securities, which primarily react to
movements in the general level of interest rates.  The market values of
fixed-income securities tend to vary inversely with the level of interest
rates.  Yields and market values of high yield securities will fluctuate over
time, reflecting not only changing interest rates but the market's perception
of credit quality and the outlook for economic growth.  When economic
conditions appear to be deteriorating, medium to lower rated securities may
decline in value due to heightened concern over credit quality, regardless of
the prevailing interest rates.  Investors should carefully consider the
relative risks of investing in high yield securities and understand that such
securities are not generally meant for short-term investing.



The high yield market is relatively new and its growth has paralleled a long
period of economic expansion and an increase in merger, acquisition and
leveraged buyout activity.  Adverse economic developments can disrupt the
market for high yield securities, and severely affect the ability of issuers,
especially highly leveraged issuers, to service their debt obligations or to
repay their obligations upon maturity which may lead to a higher incidence of
default on such securities.  In addition, the secondary market for high yield
securities, which is concentrated in relatively few market makers, may not be
as liquid as the secondary market for more highly rated securities.  As a
result, the Convertible Securities Fund could find it more difficult to sell
these securities or may be able to sell the securities only at prices lower
than if such securities were widely traded.  Furthermore, the Trust may
experience difficulty in valuing certain securities at certain times.  Prices
realized upon the sale of such lower rated or unrated securities, under these
circumstances, may be less than the prices used in calculating the Convertible
Securities Fund's net asset value.



Lower rated or unrated debt obligations also present risks based on payment
expectations.  If an issuer calls an obligation for redemption, the Convertible
Securities Fund may have to replace the security with a lower yielding
security, resulting in a decreased return for investors.  If the Convertible
Securities Fund experiences unexpected net redemptions, it may be forced to
sell its higher rated securities, resulting in a decline in the overall credit
quality of the Convertible Securities Fund's investment portfolio and
increasing the exposure of the Convertible Securities Fund to the risks of high
yield securities.






                                      S-27

<PAGE>   311

The Convertible Securities Fund may choose, at its expense or in conjunction
with others, to pursue litigation or otherwise exercise its rights as a
security holder to seek to protect the interest of security holders if it
determines this to be in the interest of the Convertible Securities Fund's
Shareholders.


OTHER INVESTMENTS

The Trust is not prohibited from investing in obligations of banks, but the
Trust may not purchase obligations of the Advisor or its affiliates.

INVESTMENT LIMITATIONS

Fundamential Policies

The following investment limitations (and those set forth in the Prospectuses)
are fundamental policies of each Fund which cannot be changed with respect to a
Fund without the consent of the holders of a majority of that Fund's
outstanding shares. The term "majority of the outstanding shares" means the
vote of (i) 67% or more of a Fund's shares present at a meeting, if more than
50% of the outstanding shares of a Fund are present or represented by proxy, or
(ii) more than 50% of a Fund's outstanding shares, whichever is less.


A Fund may not:


1.       Acquire more than 10% of the voting securities of any one issuer.  For
         the Government Securities Fund and the Limited Maturity Government
         Fund, this limitation applies to only 75% of the Fund's assets.


2.       Invest in companies for the purpose of exercising control.



3.       Borrow money, except for temporary or emergency purposes and then only
         in an amount not exceeding one-third of the value of total assets.
         Any borrowing will be done from a bank and to the extent that such
         borrowing exceeds 5% of the value of the Fund's assets, asset coverage
         of at least 300% is required.  In the event that such asset coverage
         shall at any time fall below 300%, the Fund shall, within three days
         thereafter or such longer period as the Securities and Exchange
         Commission may prescribe by rules and regulations, reduce the amount
         of its borrowings to such an extent that the asset coverage of such
         borrowings shall be at least 300%.  This borrowing provision is
         included solely to facilitate the orderly sale of portfolio securities
         to accommodate heavy redemption requests if they should occur and is
         not for investment purposes.  All borrowings will be repaid before
         making additional investments and any interest paid on such borrowings
         will reduce income.


4.       Make loans, except that (a) a Fund may purchase or hold debt
         instruments in accordance with its investment objective and policies;
         (b) a Fund may enter into repurchase agreements, and (c) the Funds may
         engage in securities lending as described in the Prospectus and in
         this Statement of Additional Information.

5.       Pledge, mortgage or hypothecate assets except to secure temporary
         borrowings permitted by (3) above in aggregate amounts not to exceed
         10% of total assets taken at current value at the time of the
         incurrence of such loan, except as permitted with respect to
         securities lending.


6.       Purchase or sell real estate, real estate limited partnership
         interests, commodities or commodities contracts (except that the
         Government Securities, Balanced, Blue Chip Growth, Emerging Growth and
         International Equity Funds may invest in futures contracts and 
         options on futures contracts, as disclosed in the prospectuses) and
         interests in a pool of securities that are secured by interests in
         real estate. However, subject to their permitted investments, any Fund
         may invest in companies which invest in real estate, commodities or
         commodities contracts.


7.       Make short sales of securities, maintain a short position or purchase
         securities on margin, except that the Trust may obtain short-term
         credits as necessary for the clearance of security transactions.

8.       Act as an underwriter of securities of other issuers except as it may
         be deemed an underwriter in selling a Fund security.





                                      S-28

<PAGE>   312
9.       Purchase securities of other investment companies except for money
         market funds and then only as permitted by the Investment Company Act
         of 1940 and the rules and regulations thereunder.  The Emerging
         Growth, Blue Chip Growth, Convertible Securities, International Equity
         and Government Securities Funds may also purchase the securities of
         non-money market funds as permitted by the Investment Company Act of
         1940.  Under these rules and regulations, the Funds are prohibited
         from acquiring the securities of other investment companies if, as a
         result of such acquisition, the Funds own more than 3% of the total
         voting stock of the company; securities issued by any one investment
         company represent more than 5% of the total Funds' assets; or
         securities (other than treasury stock) issued by all investment
         companies represent more than 10% of the total assets of the Funds.
         These investment companies typically incur fees that are separate from
         those fees incurred directly by the Fund.  A Fund's purchase of such
         investment company securities results in the layering of expenses,
         such that Shareholders would indirectly bear a proportionate share of
         the operating expenses of such investment companies, including
         advisory fees.

10.      Issue senior securities (as defined in the Investment Company Act of
         1940) except in connection with permitted borrowings as described
         above or as permitted by rule, regulation or order of the Securities
         and Exchange Commission.


11.      Purchase or retain securities of an issuer if, to the knowledge of the
         Trust, an officer, trustee, partner or director of the Trust or any
         investment advisor of the Trust owns beneficially more than 1/2 of 1%
         of the shares or securities of such issuer and all such officers,
         trustees, partners and directors owning more than 1/2 of 1% of such
         shares or securities together own more than 5% of such shares or
         securities.


12.      Invest in interests in oil, gas or other mineral exploration or
         development programs and oil, gas or mineral leases.


13.      Write or purchase puts, calls, options or combinations thereof, except
         that the Growth Equity, Emerging Growth, Blue Chip Growth, Balanced,
         International Equity and the Value Momentum Funds may write covered
         call options with respect to any or all parts of its Fund securities,
         and the Balanced, Blue Chip Growth and Emerging Growth Funds may
         purchase call and purchase and sell put options listed on national
         exchanges and the International Equity Fund may purchase call and
         purchase and sell put options listed on U.S. and foreign exchanges. 
         The California Tax-Free Money Market Fund may purchase puts as
         described in the prospectus.  The Growth Equity, Emerging Growth, Blue
         Chip Growth, Balanced, International Equity and Value Momentum Funds
         may sell options previously purchased and enter into closing
         transactions with respect to covered call options.  In addition, the
         Growth Equity, Emerging Growth, Blue Chip Growth, Value Momentum,
         International Equity and Balanced Funds may engage in options on stock
         indices to invest cash on an interim basis.


NON-FUNDAMENTAL POLICIES

No Fund may invest in warrants, except that the Growth Equity, Emerging Growth,
Blue Chip Growth, Convertible Securities, Value Momentum, International Equity,
and Balanced Funds may invest in warrants in an amount not exceeding 5% of the
Fund's net assets as valued at the lower of cost or market value.  Included in
that amount, but not to exceed 2% of the Fund's net assets, may be warrants not
listed on the New York Stock Exchange or American Stock Exchange.


No Fund may invest in illiquid securities in an amount exceeding, in the
aggregate, 15% of its net assets, except that the Money Market Fund, Treasury
Money Market Fund and California Tax-Free






                                      S-29

<PAGE>   313
Money Market Fund may not invest more than 10% of net assets in illiquid
securities.  An illiquid security is a security which cannot be disposed of
within seven business days at approximately the price at which they are being
carried on the Fund's books, and includes repurchase agreements maturing in
excess of seven days, time deposits with a withdrawal penalty, non-negotiable
instruments and instruments for which no market exists.

The foregoing percentages will apply at the time of the purchase of a security.

THE ADVISOR


The Trust and Union Bank of California, N.A. (the "Advisor"), have entered into
an advisory agreement (the "Advisory Agreement") dated April 1, 1996.  The
Advisory Agreement provides that the Advisor shall not be protected against any
liability to the Trust or its Shareholders by reason of willful misfeasance,
bad faith or gross negligence on its part in the performance of its duties or
from reckless disregard of its obligations or duties thereunder.


The Advisory Agreement provides that if, for any fiscal year, the ratio of
expenses of any Fund (including amounts payable to the Advisor but excluding
interest, taxes, brokerage, litigation, and other extraordinary expenses)
exceeds limitations established by the State of California, the Advisor will
bear the amount of such excess.  The Advisor will not be required to bear
expenses of the Trust to an extent which would result in a Fund's inability to
qualify as a regulated investment company under provisions of the Internal
Revenue Code.

The continuance of the Advisory Agreement, after the first two years, must be
specifically approved at least annually (i) by the vote of a majority of the
Trustees who are not parties to the Agreement or "interested persons" of any
party thereto, cast in person at a meeting called for the purpose of voting on
such approval, and (ii) by the vote of the Trustees or a majority of
outstanding shares of the Funds, as defined in the 1940 Act.  The Advisory
Agreement will terminate automatically in the event of its assignment, and is
terminable at any time without penalty by the Trustees of the Trust or, with
respect to the Funds by a majority of the outstanding shares of the Funds, on
not less than 30 days' nor more than 60 days' written notice to the Advisor, or
by the Advisor on 90 days' written notice to the Trust.


The Advisor is entitled to a fee, which is calculated daily and paid monthly,
at an annual rate of .80% of the daily average net assets of the Emerging
Growth Fund, .60% of the daily average net assets of each of the Value
Momentum, Growth Equity, Blue Chip Growth, Convertible Securities and Balanced
Funds, .50% of the average daily net assets of the Intermediate-Term Bond,
California Intermediate Tax-Free Bond and Government Securities Funds, and .30%
of the average daily net assets of each of the Money Market, Treasury Money
Market, California Tax-Free Money Market, and Limited Maturity Government
Funds, and .95% of the average daily net assets of the International Equity
Fund.



For the fiscal years ended January 31, 1994, 1995 and 1996, the Funds paid the
following advisory fees to Union Capital Advisors, the Advisor's predecessor:

THE DISTRIBUTOR


SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary
of SEI, and the Trust are parties to a distribution agreement ("Distribution
Agreement") dated January 30, 1991, which applies to both Institutional Class
and Investment Class shares of the Funds.  The Distributor will receive no
compensation for distribution of Institutional Class shares.  The Investment
Class has a distribution plan dated January 30, 1991 ("Investment Class
Distribution Plan").


INVESTMENT CLASS DISTRIBUTION PLAN


The Distribution Agreement and the Investment Class Distribution Plan adopted
by the Investment Class Shareholders provides that each Investment Class Fund
will bear the cost of its distribution expenses as provided in a budget
approved annually and reviewed quarterly by the Trustees of the Trust who are
not interested persons and have no financial interest in the Plan or any
related agreement ("Qualified Trustees").  The budget includes (1) the cost of
prospectuses, reports to Shareholders, sales literature and other materials for
potential investors; (2) advertising; (3) expenses incurred in connection with
the promotion and sale of the Trust's shares including the Distributor's
expenses for travel, communication, and compensation and benefits for sales
personnel; (4) any other expenses reasonably incurred in connection with the
distribution and marketing of the Investment Class shares subject to approval
of a majority of the Qualified Trustees.  The Trust is not obligated to
reimburse the Distributor for any expenditures in excess of the approved
budget.  In addition, the Trust will pay the Distributor a fee of up to .40% of
the Investment Class Fund's average daily net assets which the Distributor can
use to compensate broker/dealers and service providers, including Union Bank
and its affiliates, which provide administrative and/or distribution services
to Investment Class Shareholders or their customers who beneficially own
Investment Class shares. The Class C shares of the Trust have also adopted a
distribution plan.



For the fiscal year ending January 31, 1996, no distribution fees were incurred
by the Institutional Class Shares of the Trust or the Investment Class Shares
of the Intermediate-Term Bond, Limited Maturity Government, California
Intermediate Tax-Free Bond, Blue Chip Growth, Convertible Securities, Emerging

Class Shares of the remaining Funds incurred the following distribution

The Distribution Agreement is renewable annually and may be terminated by the
Distributor, the Qualified Trustees, or by a majority vote of the outstanding
securities of the Trust upon not more than 60 days' written notice by either
party.


The Trust has adopted the Investment Class Distribution Plan in accordance with
the provisions of Rule 12b-1 under the Investment Company Act of 1940, which
regulates circumstances under which an investment company may directly or
indirectly bear expenses relating to the distribution of its shares.
Continuance of the Investment Class Distribution Plan must be approved annually
by a majority of the Trustees of the Trust and by a majority of the Qualified
Trustees.  The Investment Class Distribution Plan requires that quarterly
written reports of amounts spent under the Investment Class Distribution Plan
and the purposes of such expenditures be furnished to and reviewed by the
Trustees.  The Investment Class Distribution Plan may not be amended to
increase materially the amount which may be spent thereunder without approval
by a majority of the outstanding shares of the Trust.  All material amendments
of the Plan will require approval by a majority of the Trustees of the Trust
and of the Qualified Trustees.



The Trust has also adopted a Distribution Plan with respect to Class C shares
of the Trust.  Class C shares are sold without a sales charge, but are subject
to a 12b-1 fee in addition to reimbursement of certain expenses, a fee will be
paid to the Distributor at an annual rate of .50% of each Fund's average daily
net assets attributable to Class C shares as compensation for its distribution-
related services.  The Distributor may retain all or some of this payment and
may pay financial institutions and intermediaries such as banks, savings and
loan associations, insurance companies, investment counselors and subsidiaries,
as compensation for services in connection with distribution assistance or
provision of shareholder services.

REPORTING

The Trust issues unaudited financial information semi-annually and audited
financial statements annually.  The Trust furnishes proxy statements and other
Shareholder reports to Shareholders of record.

PERFORMANCE

Yields.  Yields are one basis upon which investors may compare the Funds with
other funds; however, yields of other funds and other investment vehicles may
not be comparable because of the factors set forth below and differences in the
methods used in valuing portfolio instruments.

The yields of these Money Market Funds fluctuate, and the annualization of a
week's dividend is not a representation by the Trust as to what an investment
in the Fund will actually yield in the future.  Actual yields will depend on
such variables as asset quality, average asset maturity, the type of
instruments the Fund invests in, changes in interest rates on money market
instruments, changes in the expenses of the Fund and other factors.


Money Market Fund Yields.  From time to time the Treasury Money Market, Money
Market, and California Tax-Free Money Market Funds (the "Money Market Funds")
advertise their "current yield" and "effective compound yield".  Both yield
figures are based on historical earnings and are not intended to indicate
future performance.  The "current yield" of the Money Market Funds refers to
the income generated by an investment in a Fund 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 "effective yield" is calculated similarly
but, when annualized, the income earned by an investment in a Fund is assumed
to be reinvested.  The "effective yield" will be slightly higher than the
"current yield" because of the compounding effect of this assumed reinvestment.


The current yield of the Money Market Funds will be calculated daily based upon
the seven days ending on the date of calculation ("base period").  The yield is
computed by determining the net change (exclusive of capital changes) in the
value of a hypothetical pre-existing shareholder account having a balance of
one share at the beginning of the period, subtracting a hypothetical charge
reflecting deductions from shareholder accounts, and dividing such net change
by the value of the account at the beginning of the same period to obtain the
base period return and multiplying the result by (365/7).  Realized and
unrealized gains and losses are not included in the calculation of the yield.
The effective compound yield of the Funds is determined by computing the net
change, exclusive of capital changes, in the value of a hypothetical
pre-existing account 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
compounding the base period return by adding 1, raising the sum to a power
equal to 365 divided by 7, and subtracting 1 from the result, according to the
following formula:  Effective Yield = (Base Period Return + 1) 365/7) - 1.  The
current and the effective yields reflect the reinvestment of net income earned
daily on portfolio assets.


The California Tax-Free Money Market Fund may also calculate tax-equivalent
yields.  Tax equivalent yields are computed by dividing that portion of a
Fund's yield which is tax-exempt by one minus a stated federal and/or state
income tax rate and adding the product to that portion, if any, of the Fund's
yield that is not tax-exempt.  (Tax equivalent yields assume the payment of
Federal income taxes at a rate of 31% and California income taxes at a rate of
11%.)



For the 7-day period ended January 31, 1996, the Money Market, Treasury Money
Market and California Tax-Free Money Market Funds' current, effective and
tax-equivalent yields were as follows:

Other Yields.  From time to time, Growth Equity, Value Momentum, Balanced,
Intermediate-Term Bond, Emerging Growth, Blue Chip Growth, Convertible
Securities, Government Bond and Limited Maturity Government Funds may advertise
a 30 day yield, and the California Intermediate Tax-Free Bond Fund may
advertise a 30 day yield and a  30 day tax equivalent yield.  These figures
will be based on historical earnings and are not intended to indicate future
performance.  The 30 day yield of these Funds refers to the annualized income
generated by an investment in the Funds over a specified 30 day period.  The
yield is calculated by assuming that the income generated by the investment
during that period generated each period over one year and is shown as a
percentage of the investment.  In particular, yield will be calculated
according to the following formula:


Yield = (2 (a-b/cd + 1)6 - 1) where a = dividends and interest earned during
the period; b = expenses accrued for the period (net of reimbursement); c = the
current daily number of shares outstanding during the period that were entitled
to receive dividends; and d = the maximum offering price per share on the last
day of the period.

Tax equivalent yields are computed by dividing that portion of a Fund's yield
which is tax-exempt by one minus a stated federal and/or state income tax rate
and adding the product to that portion, if any, of the Fund's yield that is not
tax-exempt.  (Tax equivalent yields assume the payment of Federal income taxes
at a rate of 31% and California income taxes at a rate of 11%.)


For the 30 day period ended January 31, 1996, the yields on the Funds, other
than the Money Market Funds, were as follows:

Total Return.  From time to time, the Funds may advertise total return on an
"average annual total return" basis and on an "aggregate total return" basis
for various periods.  Average annual total return reflects the average annual
percentage change in the value of an investment in a Fund over a particular
measuring period.  Aggregate total return reflects the cumulative percentage
change in value over the measuring period.  Aggregate total return is computed
according to a formula prescribed by the SEC.  The formula can be expressed as
follows:  P (1 + T)n = ERV, where P = a hypothetical initial payment of $1,000;
T = average annual total return; n = number of years; and ERV = ending
redeemable value of a hypothetical $1,000 payment made at the beginning of the
designated time period as of the end of such period or the life of the fund.
The formula for calculating aggregate total return can be expressed as
(ERV/P)-1.

The calculation of total return assumes reinvestment of all dividends and
capital gain distribution on the reinvestment dates during the period and that
the entire investment is redeemed at the end of the period.  In addition the
maximum sales charge for each Fund is deducted from the initial $1000 payment.
Total return may also be shown without giving effect to any sales charges.


Based on the foregoing, the average annual and aggregate total returns for the
Funds from inception through January 31, 1996, were as follows:

The Funds may quote various measures of volatility and benchmark correlation in
advertising, and may compare these measures to those of other funds.  Measures
of volatility attempt to compare historical share price fluctuations or total
returns to a benchmark while measures of benchmark correlation indicate how
valid a comparative benchmark might be.  Measures of volatility and correlation
are calculated using averages of historical data and cannot be calculated
precisely.

PURCHASE AND REDEMPTION OF SHARES

Purchases and redemptions of shares of the Funds may be made on days on which
both the New York Stock Exchange and the Federal Reserve wire systems are open
for business.

It is currently the Trust's policy to pay for the redemptions in cash.  The
Trust retains the right, however, to alter this policy to provide for
redemptions in whole or in part by a distribution in-kind of securities held by
the Funds other than the Money Market Funds in lieu of cash.  Shareholders may
incur brokerage charges on the sale of any such securities so received in
payment of redemptions.  However, a Shareholder will at all times be entitled
to aggregate cash redemptions from all Funds of the Trust during any 90-day
period of up to the lesser of $250,000 or 1% of the Trust's net assets.

The Trust reserves the right to suspend the right of redemption and/or to
postpone the date of payment upon redemption for any period on which trading on
the New York Stock Exchange is restricted, or during the existence of an
emergency (as determined by the Securities and Exchange Commission by rule or
regulation) as a result of disposal or valuation of the Fund's securities is
not reasonably practicable, or for such other periods as the Securities and
Exchange Commission has by order permitted.  The Trust also reserves the right
to suspend sales of shares of the Fund for any period during which the New York
Stock Exchange, the Advisor, the Administrator and/or the Custodian are not
open for business.

A Fund with portfolio securities listed on foreign exchanges which trade on
Saturdays or other customary United States national business holidays would be
expected to disclose to their investors, if the Fund does not price on these
days, that the portfolio will trade and the net asset of the Fund's redeemable
securities may be significantly affected on days when the investor has no
access to the Fund.

DETERMINATION OF NET ASSET VALUE

The net asset value per share of the Treasury Money Market, Money Market and
California Tax-Free Money Market Funds is calculated by adding the value of
securities and other assets, subtracting liabilities and dividing by the number
of outstanding shares.  Securities will be valued by the amortized cost method
which involves valuing a security at its cost on the date of purchase and
thereafter (absent unusual circumstances) assuming a constant amortization to
maturity of any discount or premium, regardless of the impact of fluctuations
in general market rates of interest on the value of the instrument.  While this
method provides certainty in valuation, it may result in periods during which a
security's value, as determined by this method, is higher or lower than the
price the Fund would receive if it sold the instrument.  During periods of
declining interest rates, the daily yield of the Funds may tend to be higher
than a like computation made by a company with identical investments utilizing
a method of valuation based upon market prices and estimates of market prices
for all of its portfolio securities.  Thus, if the use of amortized cost by the
Funds resulted in a lower aggregate portfolio value on a particular day, a
prospective investor in the Funds would be able to obtain a somewhat higher
yield than would result from investment in a company utilizing solely market
values, and existing investors in the Fund would experience a lower yield.  The
converse would apply in a period of rising interest rates.

The Funds' use of amortized cost and the maintenance of the Funds' net asset
value at $1.00 are permitted by regulations promulgated by Rule 2a-7 under the
Investment Company Act of 1940, provided that certain conditions are met.
These conditions currently require that the Trust maintain a dollar-weighted
average maturity in the Funds of 90 days or less, not purchase any instrument
having a remaining maturity of more than one year, and will limit its
investments to those U.S. dollar-denominated instruments which the Trustees
determine to present minimal credit risks and which are of "high quality" as
determined by any major rating service or, if not rated, are determined by the
Trustees to be of comparable quality.  The regulations also require the
Trustees to establish procedures which are reasonably designed to stabilize the
net asset value per share at $1.00 for the Funds.  Such procedures include the
determination of the extent of deviation, if any, of the Funds' current net
asset value per share calculated using available market quotations from the
Funds' amortized cost price per share at such intervals as the Trustees deem
appropriate and reasonable in light of market conditions and periodic reviews
of the amount of the deviation and the methods used to calculate such
deviation.  In the event that such deviation exceeds 1/2 of 1%, the Trustees
are required to consider promptly what action, if any, should be initiated,
and, if the Trustees believe that the extent of any deviation may result in
material dilution or other unfair results to Shareholders, the Trustees are
required to take such corrective action as they deem appropriate to eliminate
or reduce such dilution or unfair results to the extent reasonably practicable.
Such actions may include the sale of portfolio instruments prior to maturity to
realize capital gains or losses or to shorten average portfolio maturity;
withholding dividends; redeeming shares in kind; or establishing a net asset
value per share by using available market quotations.  In addition, if the
Funds incur a significant loss or liability, the Trustees have the authority to
reduce pro rata the number of shares of the Funds in each Shareholder's account
and to offset each Shareholder's pro rata portion of such loss or liability
from the Shareholder's accrued but unpaid dividends or from future dividends
while each other Fund must annually distribute at least 90% of its investment
company taxable income.

The securities of the Funds other than the Money Market Funds are valued by the
Administrator pursuant to valuations provided by an independent pricing
service.  The pricing service relies primarily on prices of actual market
transactions as well as trader quotations.  However, the service may also use a
matrix system to determine valuations, which system considers such factors as
security prices, yields, maturities, call features, ratings and developments
relating to specific securities in arriving at valuations.  The procedures of
the pricing service and its valuations are reviewed by the officers of the
Trust under the general supervision of the Trustees.  Although the methodology
and procedures are





                                      S-44

<PAGE>   328
identical, the net asset value per share of Institutional Class and Investment
Class shares of Funds other than the Money Market Funds may differ because of
the distribution expenses charged to Investment Class shares.


TAXES

FEDERAL INCOME TAX


The following is only a summary of certain income tax considerations generally
affecting a Fund and its Shareholders and is not intended as a substitute for
careful tax planning.  Shareholders are urged to consult their tax advisers
with specific reference to their own tax situations, including state and local
income tax liabilities.


ALL FUNDS


In order to qualify for treatment as a regulated investment company ("RIC")
under the Internal Revenue Code of 1986, as amended (the "Code"), each Fund
must distribute annually to its Shareholders at least the sum of 90% of its net
interest income excludable from gross income plus 90% of its investment company
taxable income (generally, net investment income plus net short-term capital
gain) (the "Distribution Requirement") and also must meet several additional
requirements.  Among these requirements are the following: (i) at least 90% of
the Fund's gross income each taxable year must be derived from dividends,
interest, payments with respect to securities loans, and gains from the sale or
other disposition of stock or securities, or certain other income; (ii) the
Fund must derive less than 30% of its gross income each taxable year from the
sale or other disposition of stocks, securities or certain other investments
held for less than three months; (iii) at the close of each quarter of the
Fund's taxable year, at least 50% of the value of its total assets must be
represented by cash and cash items, U.S. Government securities, securities of
other RICs and other securities, with such other securities limited, in respect
to any one issuer, to an amount that does not exceed 5% of the value of the
Fund's assets and that does not represent more than 10% of the outstanding
voting securities of such issuer; and (iv) at the close of each quarter of the
Fund's taxable year, not more than 25% of the value of its assets may be
invested in securities (other than U.S. Government securities or the securities
of other RICs) of any one issuer or two or more issuers engaged in same or
similar businesses if the Fund owns at least 20% of the voting power of such
issuers.


Notwithstanding the Distribution Requirement described above, which only
requires a Fund to distribute at least 90% of its annual investment company
taxable income and does not require any minimum distribution of net capital
gain (the excess of net long-term capital gain over net short-term capital
loss), a Fund will be subject to a nondeductible 4% excise tax to the extent it
fails to distribute by the end of any calendar year 98% of its ordinary income
for that year and 98% of its capital gain net income for the one-year period
ending on October 31 of that year, plus certain other amounts.



A dividends received deduction is available to corporations that receive
dividends form domestic corporations.  Dividends paid by a Fund will be
eligible for the dividends received deduction for corporate shareholders to the
extent they are derived from dividends from domestic corporations and to the
extent that the respective security has been held for at least three months.
Shareholders will be advised each year of the portion of ordinary income
dividends eligible for the deduction.



Individual shareholders are not entitled to the dividends received deduction.



ADDITIONAL CONSIDERATION FOR CALIFORNIA TAX-FREE MONEY MARKET AND TAX-FREE BOND
FUNDS






                                      S-45

<PAGE>   329

As noted in the Prospectuses for the California Tax-Free Money Market and
Tax-Free Bond Funds, exempt interest dividends are generally excludable from a
Shareholder's gross income for regular federal income tax purposes.
Exempt-interest dividends may nevertheless be subject to the alternative
minimum tax (the "Alternative Minimum Tax") imposed by Section 55 of the Code
or the environmental tax (the "Environmental Tax") imposed by Section 59A of
the Code.  The Alternative Minimum Tax is imposed at the rate of 26% (with a
maximum rate of 28%) in the case of non-corporate taxpayers and at the rate of
20% in the case of corporate taxpayers, to the extent it exceeds the taxpayer's
regular tax liability.  The Environmental Tax is imposed at the rate of 0.12%
and applies only to corporate taxpayers.  The Alternative Minimum Tax and the
Environmental Tax may be imposed in two circumstances.  First, exempt-interest
dividends derived from certain "private activity bonds" issued after August 7,
1986, will generally be an item of tax preference (and therefore potentially
subject to the Alternative Minimum Tax for both corporate and non-corporate
taxpayers and the Environmental Tax for corporate taxpayers only).  Second, in
the case of exempt-interest dividends received by corporate Shareholders, all
exempt-interest dividends, regardless of when the bonds from which they are
derived were issued or whether they are derived from private activity bonds,
will be included in the corporation's "adjusted current earnings," as defined
in Section 56(g) of the Code, in calculating the corporation's alternative
minimum taxable income for purposes of determining the Alternative Minimum Tax
and the Environmental Tax.


Any gain or loss recognized on a sale or redemption of shares of either Fund by
a Shareholder who is not a dealer in securities will generally be treated as a
long-term capital gain or loss if the shares have been held for more than
twelve months and otherwise will be generally treated as a short-term capital
gain or loss.  Any loss recognized by a Shareholder upon the sale or redemption
of shares of either Fund held for six months or less, however, will be
disallowed to the extent of any exempt-interest dividends received by the
Shareholder with respect to such shares.  If shares on which a net capital gain
distribution has been received are subsequently sold or redeemed and such
shares have been held for six months or less, any loss recognized will be
treated as a long- term capital loss to the extent of the long-term capital
gain distribution.

Interest on indebtedness incurred by Shareholders to purchase or carry shares
of the fund will not be deductible for federal income tax purposes to the
extent that the Fund distributes exempt interest dividends during the taxable
year.  The deduction otherwise allowable to property and casualty insurance
companies for "losses incurred" will be reduced by an amount equal to a portion
of exempt-interest dividends received or accrued during any taxable year.
Certain foreign corporations engaged in a trade or business in the United
States will be subject to a "branch profits tax" on their "dividend equivalent
amount" for the taxable year, which will include exempt-interest dividends.
Certain Subchapter S corporations may also be subject to taxes on their
"passive investment income", which could include exempt-interest dividends.  Up
to 85% (up to 50% for years prior to 1994) of the Social Security benefits or
railroad retirement benefits received by an individual during any taxable year
will be included in the gross income of such individual if the individual's
"modified adjusted gross income" (which includes exempt-interest dividends)
plus 50 percent of the Social Security benefits or railroad retirement benefits
received by such individual during that taxable year exceeds the base amount
described in Section 86 of the Code.


The Funds may not be an appropriate investment for persons (including
corporations and other business entities) who are "substantial users" (or
persons related to such users) of facilities financed by industrial development
or private activity bonds.  A "substantial user" is defined generally to
include certain persons who regularly use a facility financed by the proceeds
of such bonds in their trade or business.  Such entities or persons should
consult their tax advisors before purchasing shares of either Fund.






                                      S-46

<PAGE>   330

Issuers of bonds purchased by the Fund (or the beneficiary of such bonds) may
have made certain representations or covenants in connection with the issuance
of such bonds to satisfy certain requirements of the Code that must be
satisfied subsequent to the issuance of such bonds.  Investors should be aware
that exempt-interest dividends derived from such bonds may become subject to
federal income taxation retroactively to the date of issuance of such bonds to
which such dividends are attributable if such representations are determined to
have been inaccurate or if the issuer of such bonds (or the beneficiary of such
bonds) fails to comply with such covenants.



If a Fund should fail to qualify as a regulated investment company for any
taxable year, the Fund would pay tax on its taxable investment income and
capital gains at regular corporate rates without any deductions for amounts
distributed to Shareholders.  In addition, all of the Fund's distributions to
Shareholders would be taxable as ordinary income and would qualify for the
corporate dividends-received deduction in the case of corporate shareholders.


FOREIGN TAXES


Dividends and interest received by a Fund may be subject to income, withholding
or other taxes imposed by foreign countries and U.S.  possessions that would
reduce the yield on the Fund's securities.  Tax conventions between certain
countries and the United States may reduce or eliminate these taxes.  Foreign
countries generally do not impose taxes on capital gains with respect to
investments by foreign investors.  If a Fund meets the Distribution Requirement
and if more than 50% of the value of the Fund's total assets at the close of
its taxable year consists of securities of foreign corporations, the Fund will
be eligible to file an election with the Internal Revenue Service that will
enable Shareholders, in effect, to receive the benefit of the foreign tax
credit with respect to any foreign and U.S. possessions income taxes paid by
the Fund.  Pursuant to the election, the Fund will treat those taxes as
dividends paid to its Shareholders.  Each Shareholder will be required to
include a proportionate share of those taxes in gross income as income received
from a foreign source and must treat the amount so included as if the
Shareholder had paid the foreign tax directly.  The Shareholder may then either
deduct the taxes deemed paid by him or her in computing his or her taxable
income or, alternatively, use the foregoing information in calculating the
foreign tax credit against the Shareholder's federal income tax.  If a Fund
makes the election, it will report annually to its Shareholders the respective
amounts per share of the Fund's income from sources within, and taxes paid to,
foreign countries and U.S. possessions.


STATE TAXES


A Fund is generally not liable for any income or franchise tax in Massachusetts
if it qualifies as a RIC for federal income tax purposes.  Depending upon
applicable state and local law, distributions by the Funds to Shareholders and
the ownership of shares may be subject to state and local taxes.


Many states allow income received from certain United States Government
obligations that is tax exempt when received directly to be tax exempt when
received as income dividends from an investment company.  Not all states permit
such income dividends to be tax exempt and some require that a certain minimum
percentage of an investment company's income dividend be derived from state
tax- exempt interest before any portion of the income dividends may be exempt.
The Funds will inform Shareholders annually of the percentage of income that is
derived from direct United States Government obligations.  Shareholders should
consult their tax advisors to determine whether any portion of the income
dividends received from a Fund is considered tax exempt in their particular
states.

FUND TRANSACTIONS

The Trust has no obligation to deal with any dealer or group of dealers in the
execution of transactions in portfolio securities.  Subject to policies
established by the Trustees, the Advisor is responsible for placing the orders
to execute transactions for the Fund.  In placing orders, it is the policy of
the Trust to seek to obtain the best net results taking into account such
factors as price (including the applicable dealer spread), the size, type and
difficulty of the transaction involved, the firm's general execution and
operational facilities, and the firm's risk in positioning the securities
involved.  While the Advisor generally seeks reasonably competitive spreads or
commissions, the Trust will not necessarily be paying the lowest spread or
commission available.  The Trust will not purchase portfolio securities from
any affiliated person acting as principal except in conformity with the
regulations of the Securities and Exchange Commission (the "SEC").

The money market securities in which the Funds invest are traded primarily in
the over-the-counter market.  Bonds and debentures are usually traded
over-the-counter, but may be traded on an exchange.  Where possible, the
Advisor will deal directly with the dealers who make a market in the securities
involved except in those circumstances where better prices and execution are
available elsewhere.  Such dealers usually are acting as principal for their
own account.  On occasion, securities may be purchased directly from the
issuer.  Money market securities are generally traded on a net basis and do not
normally involve either brokerage commissions or transfer taxes.  The cost of
executing portfolio securities transactions of the Trust will primarily consist
of dealer spreads and underwriting commissions.

The Trust does not expect to use one particular dealer, but subject to the
Trust's policy of seeking the best net results, dealers who provide
supplemental investment research to the Advisor may receive orders for
transactions by the Trust.  Information so received will be in addition to and
not in lieu of the services required to be performed by the Advisor under the
Advisory Agreement, and the expenses of the Advisor will not necessarily be
reduced as a result of the receipt of such supplemental information.


It is expected that the Trust may execute brokerage or other agency
transactions through the Distributor or an affiliate of the Advisor, both of
which are registered broker-dealers, for a commission in conformity with the
1940 Act, the Securities Exchange Act of 1934 and rules promulgated by the SEC.
Under these provisions, the Distributor (or an affiliate of the Advisor) is
permitted to receive and retain compensation for effecting portfolio
transactions for the Trust on an exchange if a written contract is in effect
between the Distributor and the Trust expressly permitting the Distributor (or
an affiliate of the Advisor) to receive and retain such compensation.  These
rules further require that commissions paid to the Distributor by the Trust for
exchange transactions not exceed "usual and customary" brokerage commissions.
The rules define "usual and customary" commissions to include amounts which are
"reasonable and fair compared to the commission, fee or other remuneration
received or to be received by other brokers in connection with comparable
transactions involving similar securities being purchased or sold on a
securities exchange during a comparable period of time."  In addition,  the
Funds may direct commission business to one more designated broker/dealers,
including the Distributor, in connection with such broker/dealer's payment of
certain of the Fund's expenses.  The Trustees, including those who are not
"interested persons" of the Trust, have adopted procedures for evaluating the
reasonableness of commissions paid to the Distributor and will review these
procedures periodically.


Since the Trust does not market its shares through intermediary broker-dealers,
it is not the trust's practice to allocate brokerage or principal business on
the basis of sales of its shares which may be made through such firms.
However, the Advisor may place Fund orders with qualified broker-dealers who
recommend the Trust to clients, and may, when a number of brokers and dealers
can provide

recommendations by a broker or dealer in selecting among broker- dealers.

DESCRIPTION OF SHARES

The Declaration of Trust authorizes the issuance of an unlimited number of
shares of each series and of each class of shares thereof.  Each Institutional
and Investment Class share of that Fund represents an equal proportionate
interest in that Fund with each other Institutional and Investment Class shares
of that Fund.  Shares are entitled upon liquidation to a pro rata share in the
net assets of the Funds, Shareholders have no preemptive rights.  The
Declaration of Trust provides that the Trustees of the Trust may create
additional series of shares.  All consideration received by the Trust for
shares of any additional series and all assets in which such consideration is
invested would belong to that series and would be subject to the liabilities
related thereto.  Share certificates representing shares will not be issued.

SHAREHOLDER LIABILITY

The Trust is an entity of the type commonly known as a "Massachusetts business
trust".  Under Massachusetts law, shareholders of such a trust could, under
certain circumstances, be held personally liable for the obligations of the
Trust.  Even if, however, the Trust were held to be a partnership, the
possibility of the Shareholders'

incurring financial loss for that reason appears remote because The Trust's
Declaration of Trust contains an express disclaimer of Shareholder liability
for obligations of the Trust and requires that notice of such disclaimer be
given in each agreement, obligation or instrument entered into or executed by
or on behalf of the Trust or the Trustees, and because the Declaration of Trust
provides for indemnification out of the Trust property for any Shareholder held
personally liable for the obligations of the Trust.

LIMITATION OF TRUSTEES' LIABILITY


The Declaration of Trust provides that a Trustee shall be liable only for his
own willful defaults and, if reasonable care has been exercised in the
selection of officers, agents, employees or investment advisors, shall not be
liable for any neglect or wrongdoing of any such person.  The Declaration of
Trust also provides that the Trust will indemnify its Trustees and officers
against liabilities and expenses incurred in connection with actual or
threatened litigation in which they may be involved because of their offices
with the Trust unless it is determined in the manner provided in the
Declaration of Trust that they have not acted in good faith in the reasonable
belief that their actions were in the best interests of the Trust.  However,
nothing in the Declaration of Trust shall protect or indemnify a Trustee
against any liability for his willful misfeasance, bad faith, gross negligence
or reckless disregard of his duties.


5% SHAREHOLDERS


As of March 5, 1996 the following persons were the only persons who were record
owners (or to the knowledge of the Trust, beneficial owner) of 5% or more of
the shares of the Funds.  The Trust believes that most of the shares referred
to below were held by the persons indicated in accounts for their fiduciary,
agency, or custodial customers.

NOTES TO FINANCIAL STATEMENTS 
- --------------------------------------------------------------------------------
Stepstone Funds

1. Organization

Stepstone Funds (the "Trust" or the "Fund") was organized as a Massachusetts
business trust under a Declaration of Trust dated October 16, 1990.

The Trust is registered under the Investment Company Act of 1940, as amended,
as a diversified open-end investment company with fourteen funds: the Treasury
Money Market Fund, the Money Market Fund and the California Tax-Free Money
Market Fund (the "Money Market Funds") and the Intermediate-Term Bond Fund, the
Limited Maturity Government Fund, the California Tax-Free Bond Fund, the
Convertible Securities Fund, the Government Securities Fund, the Balanced Fund,
the Growth Equity Fund, the Value Momentum Fund, the Blue Chip Growth Fund, the
Emerging Growth Fund, and the International Equity Fund (the "Non-Money Market
Funds"). The Trust is registered to offer two classes of shares, Institutional
and Investment. The Funds' prospectus provides a description of each fund's
investment objectives, policies and strategies.

2. Significant Accounting Policies

The following is a summary of significant accounting policies followed by the
Trust.

         Security Valuation -- Investment securities held by the Money Market
         Funds are stated at amortized cost, which approximates market value.
         Under this valuation method, purchase discounts and premiums are
         accreted and amortized ratably to maturity and are included in
         interest income.

         Investments in equity securities held by the Non-Money Market Funds
         which are traded on a national securities exchange (or reported on the
         NASDAQ national market system) are stated at the last quoted sales
         price if readily available for such equity securities on each business
         day; other equity securities traded in the over-the-counter market and
         listed equity securities for which no sale was reported on that date
         are stated at the last quoted bid price. Option contracts are valued
         at the last quoted bid price as quoted on the primary exchange or
         board of trade which such option contracts are traded. Debt
         obligations exceeding sixty days to maturity for which market
         quotations are readily available are valued at the most recently
         quoted bid price. Debt obligations with sixty days or less remaining
         until maturity may be valued at their amortized cost. Restricted
         securities for which quotations are not readily available are valued
         at fair value using methods determined in good faith under general
         Trustee supervision.

         Foreign Currency Translation -- The books and records of the Fund are
         maintained in U.S. dollars. Foreign currency amounts are translated
         into U.S. dollars on the following basis: (I) market value of
         investment securities, other assets and liabilities at the current
         rate of exchange; and (II) purchases and sales of investment
         securities, income and expenses at the relevant rates of exchange
         prevailing on the respective dates of such transactions.

         The Fund does not isolate that portion of gains and losses on
         investments in securities which is due to changes in the foreign
         exchange rates from that which is due to changes in market prices of
         such securities.

         The Fund reports gains and losses on foreign currency related
         transactions as realized and unrealized gains and losses for financial
         reporting purposes, whereas such gains and losses are treated as
         ordinary income or loss for U.S. Federal income tax purposes.

         Federal Income Taxes -- It is each Fund's intention to continue to
         qualify as a regulated investment company for Federal income tax
         purposes and distribute all of its taxable income and net capital
         gains. Accordingly, no provision for Federal income taxes is required.

         The International Equity Fund may be subject to taxes imposed by
         countries in which it invests with respect to its investments in
         issuers existing or operating in such countries. Such taxes are
         generally based on either income earned or repatriated. The
         International Equity Fund accrues such taxes when the related income
         is earned.

- --------------------------------------------------------------------------------

         Net Asset Value Per Share -- The net asset value per share is
         calculated on each business day for each Fund. In general, it is
         computed by dividing the assets of each Fund, less its liabilities, by
         the number of outstanding shares of each Fund.

         Discounts and Premiums -- Discounts and premiums are accreted or
         amortized over the life of each security and are recorded as interest
         income for each of the Funds using a method which approximates the
         effective interest method.

         Classes -- Class specific expenses are borne by that class. Income,
         non-class specific expenses and realized/unrealized gains and losses
         are allocated to the respective classes on the basis of the relative
         daily net assets.

         Repurchase Agreements -- Securities pledged as collateral for
         Repurchase Agreements are held by the custodian bank until the
         respective agreements mature. Provisions of repurchase agreements and
         procedures adopted by the Adviser ensure that the market value of the
         collateral is sufficient in the event of default by the counterparty.
         If the counterparty defaults and the value of the collateral declines
         or if the counterparty enters an insolvency proceeding, realization of
         the collateral by the fund may be delayed or limited.

         Options Transactions -- In order to produce incremental earnings,
         protect gains, and facilitate buying and selling of securities for
         investment purposes, the Growth Equity Fund, the Value Momentum Fund,
         the Blue Chip Growth Fund, the Emerging Growth Fund, the Balanced and
         International Equity Fund may write covered call options. A risk in
         writing a call option is that the fund gives up the opportunity of
         profit if the market price of the underlying security increases.

         The Fund realizes a gain upon the expiration of a written call option.
         When a written call option is closed prior to expiration by being
         exercised, the proceeds on the sale are increased by the amount of
         original premium received.

         The Blue Chip Growth Fund, Emerging Growth Fund, the Balanced Fund and
         International Equity may purchase options with respect to securities
         that are permitted investments. The risk in purchasing options is
         limited to the premium paid.

         The Fund recognizes a gain when the underlying securities' market
         price rises (in case of a call) or falls (in case of a put) to the
         extent sufficient to cover the option premium and transaction costs.

         Security Transactions and Investment

         Income -- Security transactions are accounted for on the date the
         security is purchased or sold (trade date). Costs used in determining
         realized gains and losses on the sale of investment securities are
         those of the specific securities sold adjusted for the accretion and
         amortization of purchase discounts and premiums during the respective
         holding periods. Interest income is recorded on the accrual basis;
         dividend income is recorded on the ex-dividend date.

         Distributions to Shareholders -- Dividends from net investment income
         for the money market funds and the Limited Maturity Government Fund
         are declared daily and paid monthly. Each of the non-money market
         funds except the Limited Maturity Government Fund declare and pay
         dividends from net investment income monthly. Any net realized capital
         gains will be distributed at least annually for all Funds.

         Reclassification on Components of Net Assets -- In accordance with
         Statement of Position 93-2, "Determination, Disclosure, and Financial
         Statement Presentation of Income, Capital Gain, and Return of Capital
         Distribution by Investment Companies", $201,146, $134,711, $178,166
         and $111,110 relating to differences attributable to the
         classification of short-term capital gains and net investment income
         for tax distribution purposes of the Growth Equity, Value Momentum,
         Balanced and Intermediate-Term Bond Funds, respectively, as of january
         31, 1996 have been reclassified between the Fund's accumulated net
         realized gains/losses and undistributed net income accounts, as
         appropriate. These reclassifications had no effect on net asset value.





                                                                             67

administrative and shareholder services for an annual fee of .15% on the first
$1 billion of aggregate net assets, .12% on the aggregate net assets from $1
billion to $2 billion, and .10% on the aggregate net assets in excess of $2
billion. The Administrator's fee is allocated to the funds based on the
percentage of each fund's average net assets to the total average net assets of

a distribution agreement dated January 30, 1991. No compensation is paid to the
Distributor for services rendered to the Institutional Class under this
agreement. The Trust has adopted a Distribution Plan (the "Plan") on behalf of

The aggregate amount of fees paid to unaffiliated Trustees during the year was
approximately $54,000.

and are being amortized over sixty months commencing with operations. In the
event any of the initial shares of the Trust are redeemed by thereof during the
period that the Trust is amortizing its organizational costs, the redemption
proceeds payable to the holder thereof by the Trust will be reduced by the
unamortized organizational costs in the same ratio as the number of initial
shares being redeemed bears to the number of initial shares outstanding at the
time of redemption. Such costs include legal fees for organizational work
performed by a law firm of which an officer of the Fund is a partner.

During the period ended January 31, 1995, Union Bank, an affiliate of the
Advisor, purchased securities from the Money Market Fund for $19,912,500 which
represented the amortized cost and carrying value of the securities. The
securities aggregate market value was $19,305,900 at the time of purchase. This
transaction has been recorded on the books as a realized capital loss of
$606,600 on investment in the statement of operations, and as a contribution of
capital on the books for $606,600. the transactions did not change the net
asset value of the Fund.

4. Investment Advisory Agreement

The Trust and Union Capital Advisors, a division of Union Bank, (the "Advisor")
are parties to an Advisory Agreement. For its services, the Advisor is entitled
to receive a fee, which is calculated daily and paid monthly, at an annual rate
of .30% of the average daily net assets of the Treasury Money Market Fund, the
Money Market Fund, the California Tax-Free Money Market Fund and the Limited
Maturity Government Fund, .60% of the Growth Equity Fund, the Value Momentum
Fund, the Blue Chip Growth Fund, the Balanced Fund and the Convertible
Securities Fund, .50% of the Intermediate-Term Bond Fund, the Government
Securities Fund and the California Tax-Free Bond Fund, .80% of the Emerging

its fee in the Treasury Money Market Fund, the California Tax-Free  Money
Market Fund, the International Equity Fund, and the California Tax-Free Bond
Fund in order to limit the operating expenses of the Funds.

The Advisor and The Bank of Tokyo Trust Company are parties to a Sub-Advisory
Agreement on the Blue Chip Growth Fund, the Emerging Growth Fund, the
Convertible Securities Fund and the Government Securities Fund. The Bank of

merger, the resulting Bank will change its name to Union Bank of California,

The Growth Equity and Blue Chip Funds utilized their entire capital loss
carryforward balance of $1,206,611 and $617,659, respectively, which was
carried over from the previous year. The Intermediate-Term Bond and Government
Securities Funds used $2,740,091 and $1,465,927, respectively, of its capital
loss carryforward from the previous year.

6. Concentration of Credit Risk

The California Tax-Free Money Market Fund and the California Tax-Free Bond Fund
invest in debt securities in the State of California. The ability of the
issuers of the securities held by the Funds to meet their obligations may be
affected by economic developments in that state.  

The International Equity Fund invests in securities of foreign issuers
in various countries. These investments may involve certain considerations and
risks not typically associated with investments in the United States, as a
result of, among other factors, the possibility of future political and
economic developments and the level of governmental supervision and regulation
of securities markets in the respective countries.

January 31, 1996, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

APPENDIX


The nationally recognized statistical rating organizations (individually, an
"NRSRO") that may be utilized by Advisor or, where applicable, SubAdvisor with
regard to portfolio investments for the Funds include Moody's Investors
Service, Inc. ("Moody's"), Standard & Poor's Corporation ("S&P"), and Fitch
Investors Service, Inc. ("Fitch").  Set forth below is a description of the
relevant ratings of each such NRSRO.  The NRSROs that may be utilized by
Midlantic Bank, N.A. and the description of each NRSRO's ratings is as of the
date of this Statement of Additional Information, and may subsequently change.


Long-Term Debt Ratings (may be assigned, for example, to corporate and
municipal bonds)

Description of the four highest long-term debt ratings by Moody's (Moody's
applies numerical modifiers (1, 2, and 3) in each rating category to indicate
the security's ranking within the category):

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

         Aa      Bonds which 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 risk appear somewhat
                 larger than in Aaa securities.

         A       Bonds which are rated A 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.

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

Description of the four highest long-term debt ratings by S&P (S&P may apply a
plus (+) or minus (-) to a particular rating classification to show relative
standing within that classification):

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

         AA      Debt rated AA has a very strong capacity to pay interest and
                 repay principal and differs from the higher rated issues only
                 in small degree.





                                      A-1

<PAGE>   403
         A       Debt rated A 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.

         BBB     Debt rated BBB is regarded as having an adequate capacity to
                 pay interest and repay principal.  Whereas it normally
                 exhibits adequate protection parameters, adverse economic
                 conditions or changing circumstances are more likely to lead
                 to a weakened capacity to pay interest and repay principal for
                 debt in this category than in higher rated categories.

Description of the three highest long-term debt ratings by Fitch (plus or minus
signs are used with a rating symbol to indicate the relative position of the
credit within the rating category):

         AAA     Bonds 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.

         AA      Bonds 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 "[-]+."

         A       Bonds 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.

Short-Term Debt Ratings (may be assigned, for example, to commercial paper,
master demand notes, bank instruments, and letters of credit)

Moody's description of its three highest short-term debt ratings:

         Prime-1 Issuers rated Prime-1 (or supporting institutions) have a
                 superior capacity for repayment of senior short-term
                 promissory obligations.  Prime-1 repayment capacity will
                 normally be evidenced by many of the following
                 characteristics:

                                -Leading market positions in well-established
industries.

                                -High rates of return on funds employed.

                                -Conservative capitalization structures with
                                moderate reliance on debt and ample asset
                                protection.

                                -Broad margins in earnings coverage of fixed
                                financial charges and high internal cash
                                generation.

                                -Well-established access to a range of financial
                                markets and assured sources of alternate
                                liquidity.

         Prime-2 Issuers rated Prime-2 (or supporting institutions) have a
                 strong capacity for repayment of senior short-term debt
                 obligations.  This will normally be evidenced





                                      A-2

<PAGE>   404
                 by many of the characteristics cited above but to a lesser
                 degree.  Earnings trends and coverage ratios, while sound, may
                 be more subject to variation.  Capitalization characteristics,
                 while still appropriate, may be more affected by external
                 conditions.  Ample alternate liquidity is maintained.

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

S&P's description of its three highest short-term debt ratings:

         A-1     This designation indicates that the degree of safety regarding
                 timely payment is strong.  Those issues determined to have
                 extremely strong safety characteristics are denoted with a
                 plus sign (+).

         A-2     Capacity for timely payment on issues with this designation is
                 satisfactory.  However, the relative degree of safety is not
                 as high as for issues designated "A-1."

         A-3     Issues carrying this designation have adequate capacity for
                 timely payment.  They are, however, more vulnerable to the
                 adverse effects of changes in circumstances than obligations
                 carrying the higher designations.

Fitch's description of its three highest short-term debt ratings:

         F-1+    Exceptionally Strong Credit Quality.  Issues assigned this
                 rating are regarded as having the strongest degree of
                 assurance for timely payment.

         F-1     Very Strong Credit Quality.  Issues assigned this rating
                 reflect an assurance of timely payment only slightly less in
                 degree than issues rated F-1+.

         F-2     Good Credit Quality.  Issues assigned this rating have a
                 satisfactory degree of assurance for timely payment, but the
                 margin of safety is not as great as for issues assigned F-1+
                 or F-1 ratings.

         F-3     Fair Credit Quality.  Issues assigned this rating have
                 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.

Short-Term Loan/Municipal Note Ratings

Moody's description of its two highest short-term loan/municipal note ratings:

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

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





                                      A-3

<PAGE>   405
S&P's description of its two highest municipal note ratings:

          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.
