EXAMPLE:
 
An investor would pay the following expenses on a $1,000 investment assuming (1)
a 5% annual return and (2) redemption at the end of each period.

</TABLE>
 
   
(1) Average net assets have been computed on the basis of net assets at
    month-end. TRAINER, WORTHAM TOTAL RETURN BOND FUND does not have a
    Distribution Plan. The maximum fee allowable under 12b-1 Plan for both FIRST
    MUTUAL FUND and TRAINER, WORTHAM EMERGING GROWTH FUND is 0.25%. As a result
    of expenses payable in connection with these Funds' Rule 12b-1 Plan, it is
    possible that long-term shareholders may pay more than the economic
    equivalent of the maximum front-end sales charges by the National
    Association of Securities Dealers.
    
 
(2) Expenses for FIRST MUTUAL FUND reflect those actually incurred for the
    fiscal year ended June 30, 1997.
 
   
(3) The expenses shown for the Emerging Growth Fund reflect continuation of the
    Advisor's voluntary waiver of fees and/or reimbursement of expenses, which
    limited total fund operating expenses to 1.25% from October 1, 1996
    (commencement of operations) through June 30, 1997. Such limitations may be
    raised or eliminated at the discretion of the Advisor after the Fund's net
    assets exceed $7.5 million. Absent such waivers and reimbursement,
    management fees, 12b-1 fees, other expenses, and total fund operating
    expenses would have been 1.25%, 0.50%, 6.90%, and 8.65%, respectively. On
    October 21, 1997, the Board of Trustees elected to reduce the maximum fee
    allowable under the Fund's Distribution Plan from 0.50% to 0.25%, and the
    above ratios have been restated accordingly.
    
 
(4) The expenses shown for the Total Return Bond Fund reflect continuation of
    the Advisor's voluntary waiver of fees and/or reimbursement of expenses,
    which limited total fund operating expenses to 0.75% for the period from
    October 1, 1996 (commencement of operations) through April 30, 1997.
    Effective May 1, 1997, the limitation was raised to 1.20% as the Fund's net
    assets exceed $7.5 million and the above ratios have been restated
    accordingly. Absent any waivers and reimbursements, management fees,
    estimated other expenses, and approximate total fund operating expenses
    would be 0.45%, 1.65%, and 2.10%, respectively.

THE FOREGOING EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR
FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 
The purpose of the table above is to assist an investor in understanding the
various costs and expenses that an investor will bear directly or indirectly.
The Funds do not impose any sales load, redemption or exchange fees; however,
the Transfer Agent currently charges investors who request redemptions by wire
transfer a fee of $9 for each transaction. For more complete descriptions of the
various costs and expenses, see the sections entitled "MANAGEMENT OF THE TRUST,"
and "DISTRIBUTION PLAN."

                       INVESTMENT OBJECTIVES AND POLICIES
 
FIRST MUTUAL FUND:
 
The Fund's primary investment objective is to seek capital appreciation
principally through investments in common stock. The Fund may also invest in
securities convertible into common stock such as convertible bonds or preferred
stock. Its secondary investment objective is to seek income from dividends and
interest. Due to the risks inherent in any investment program, the Fund cannot
ensure that its investment objective will be realized. The value of a share of
the Fund will fluctuate as the values of the securities in the Fund's portfolio
fluctuate.
 
The Fund will invest primarily in common stock and in securities convertible
into common stock. The Fund's investment strategy will emphasize companies that,
in the opinion of the Advisor, offer prospects for capital growth and growth of
earnings and dividends. The Advisor may deem it appropriate to invest in other
types of securities, consisting of obligations of the U.S. Government, its
agencies or instrumentalities. There is no limitation as to the proportion of
the Fund's assets which may be invested in any class of securities.
 
When, in the opinion of the Advisor, a defensive investment posture is
warranted, the Fund is permitted to invest temporarily and without limitation in
U.S. Government obligations, money market instruments (such as U.S. Treasury
bills, commercial paper, certificates of deposit and banker's acceptances) and
repurchase agreements. Assets so invested will be productive and yet readily
available (when markets are deemed attractive) for reinvestment in accordance
with the Fund's principal investment policies.
 
The equity securities in which the Fund invests will be traded on a national
securities exchange or traded in the over-the-counter market. Up to 15% of the
Fund's net assets may be invested in foreign securities in the form of American
Depository Receipts ("ADRs"). The Fund does not expect to invest in unsponsored
ADRs. See "INVESTMENT STRATEGIES AND RISK CONSIDERATIONS."
 
Although the Fund's portfolio is professionally managed, the Fund may suffer a
loss on investments resulting in a lower net asset value. The likelihood of loss
is greater than that for funds with more conservative investment policies.
 
TRAINER, WORTHAM EMERGING GROWTH FUND:
 
The Fund's investment objective is to seek capital appreciation through
investments in the common stock of emerging growth companies. Emerging growth
companies are defined by the Advisor as companies that are achieving, or about
to achieve, rapid earnings growth due to a new product, a new industry,
technological innovation, new management, or a novel strategic corporate
positioning, among other factors. The weighted average market capitalization of
holdings in the Fund will be approximately $1 billion. The Fund seeks to
outperform equity returns generated by relevant benchmark indices such as the
Russell 2500 Index and S&P Small-Cap Index, as well as mutual fund indices for
funds with comparable investment objectives. The Fund seeks to meet this
objective by employing proprietary, fundamental, technical and valuation
analysis in the selection of small capitalization, publicly traded U.S.
companies. Due to the inherent risk in any investment program, the Fund cannot
ensure that its investment objectives will be realized. The value of a Fund
share will fluctuate as the value of the securities in the Fund's portfolio
fluctuate.
 
The Fund will normally invest at least 95% of the value of its total assets
(except when maintaining a temporary defensive position) in the common stock of
emerging growth companies as defined above. The Fund will invest in companies
that are achieving rapid earnings growth either as the result of new products, a
new corporate operating strategy, technological innovation, financial
recapitalization or new management among other factors. In general, companies
achieving strong earnings growth have higher near-term appreciation potential
than companies that are growing more slowly, out-of-favor "value" stocks, or
cyclical stocks. The Fund will seek to limit risk by investing only in companies
that can be accumulated at what the Advisor deems reasonable valuations, and by
avoiding situations in which financial distress is apparent or imminent. The
 
                                        6
<PAGE>   10
 
Fund will also contain risk through diversification; no single investment will
constitute more than 5% of the Fund at cost.
 
When, in the opinion of the Advisor, a defensive investment posture is
warranted, the Fund is permitted to invest temporarily and without limitation in
U.S. Government obligations, money market instruments (such as U.S. Treasury
bills, commercial paper, certificates of deposit and banker's acceptances) and
repurchase agreements. Assets so invested will be productive and yet readily
available (when markets are deemed attractive) for reinvestment in accordance
with the Fund's principal investment policies.
 
The equity securities in which the Fund invests will be traded on a national
securities exchange or traded in the over-the-counter market. Up to 15% of the
Fund's net assets may be invested in foreign securities in the form of American
Depository Receipts ("ADRs"). The Fund does not expect to invest in unsponsored
ADRs. See "INVESTMENT STRATEGIES AND RISK CONSIDERATIONS."
 
Although the Fund's portfolio is professionally managed, the Fund may suffer a
loss on investments resulting in a lower net asset value. The likelihood of loss
is greater than that for funds with more conservative investment policies.
 
TRAINER, WORTHAM TOTAL RETURN BOND FUND:
 
The Fund seeks to maximize total return consistent with preservation of capital.
The Fund will invest in U.S. Government and agency securities, investment-grade
corporate bonds and other fixed-income securities. The Fund will seek to produce
conservative, risk adjusted returns. Above all, management attempts to preserve
principal, compound interest and produce superior results over the course of a
full business cycle.
 
The Advisor relies on historical yield relationships as a basis for determining
the Fund's portfolio structure. The Advisor's securities selection process
involves strategic decision making which considers portfolio sector composition,
maturity structure and duration. The Advisor's management analyzes yield ratios
and implements a disciplined process which helps to have the Fund's portfolio
positioned to be compared to the Lehman Aggregate Index. Although the Advisor
actively manages its portfolios, it does not consider itself to be a market
timer. All changes to the portfolio are made after gradual and careful
consideration. The Advisor anticipates a turnover rate of less than 100%.
 
When the Fund has determined that adverse market and economic conditions
warrant, the Fund may invest all or part of its assets in high-quality money
market securities and repurchase agreements for temporary defensive purposes.
 
The Fund invests at least 65% of the value of its total assets (except when
maintaining a temporary defensive position) in fixed-income securities (which it
defines as bonds, debentures and other fixed-income securities). The Fund is
permitted to invest in a broad range of investment-grade, U.S. dollar
denominated fixed-income securities and securities with debt-like
characteristics (e.g., bearing interest or having stated principal) of domestic
and foreign issuers. These debt securities include: bonds, debentures, notes,
money market instruments (including foreign bank obligations, such as time
deposits, certificates of deposit and bankers' acceptances, commercial paper and
other short-term corporate debt obligations, and repurchase agreements),
mortgage-related securities (including interest-only and principal-only stripped
mortgage-backed securities), asset-backed securities, municipal obligations and
convertible debt obligations. The issuers may include domestic and foreign
corporations, partnerships or trusts, and governments or their political
subdivisions, agencies or instrumentalities. Under normal market conditions, the
Fund seeks to provide performance results that equal or exceed the Solomon
Brothers Broad Investment-Grade (BIG) Bond Index, which is a
market-capitalization weighted index that includes U.S. Treasury, Government-
sponsored, mortgage and investment-grade fixed-rate corporate fixed-income
securities with a maturity of one year or longer and a minimum of $50 million
amount outstanding at the time of inclusion.
 
At least 75% of the value of the Fund's net assets must consist of securities
which, in the case of bonds and other debt instruments, are rated no lower than
"A" by Moody's Investors Service, Inc. ("Moody's"), Standard & Poor's
Corporation ("S&P"), Fitch Investors Service,
 
                                        7
<PAGE>   11
 
Inc. ("Fitch") or Duff & Phelps, Inc. ("Duff"). Up to 25% of the value of the
Fund's net assets may consist of securities which, in the case of bonds and
other debt instruments, are rated no lower than "Baa" by Moody's and "BBB" by
S&P. The Fund may invest in short-term fixed-income obligations which are rated
in the two highest rating categories by Moody's, S&P, Fitch or Duff. See
"INVESTMENT STRATEGIES AND RISK CONSIDERATIONS -- Fixed-Income Securities."
 
Although the Fund is professionally managed, the Fund may suffer a loss on
investments resulting in a lower net asset value.
 
                           INVESTMENT STRATEGIES AND
                              RISK CONSIDERATIONS
 
Shareholders should understand that all investments involve risk and there can
be no guarantee against loss resulting from an investment in the Funds, nor can
there be any assurance that any Fund's investment objective will be attained.
 
REPURCHASE AGREEMENTS
 
Each Fund may enter into repurchase agreements with respect to permissible
portfolio securities. Under the terms of a repurchase agreement, the Funds would
acquire securities from financial institutions such as banks and registered
broker-dealers which the Advisor deems creditworthy under guidelines approved by
the Board of Trustees, subject to the seller's agreement to repurchase such
securities at a mutually agreed-upon date and price. The repurchase price would
generally equal the price paid by the Funds plus interest negotiated on the
basis of then-current short-term rates, which may be more or less than the rate
on the underlying portfolio securities. The seller under a repurchase agreement
will be required to maintain the value of collateral held pursuant to the
agreement at not less than 102% of the repurchase price (including accrued
interest). If the seller were to default on its repurchase obligation or become
insolvent, the Funds would suffer a loss to the extent that the proceeds from a
sale of the underlying portfolio securities were less than the repurchase price
under the agreement, or to the extent that the disposition of such securities by
the Funds were delayed pending court action. It is the intent of each Fund to
utilize repurchase agreements to invest idle funds for short periods of time.
Securities subject to repurchase agreements will be held by the Funds' Custodian
or in the Federal Reserve/Treasury book-entry system. Repurchase agreements are
considered to be loans by the Funds under the Investment Company Act of 1940, as
amended (the "Act").
 
MONEY MARKET INSTRUMENTS
 
Each Fund may invest, in the following types of money market instruments, each
of which at the time of purchase must have or be deemed to have under rules of
the Securities and Exchange Commission remaining maturities of 13 months or
less. The Funds may invest in money market instruments and debt securities,
including bank obligations and commercial paper, which are at least comparable
in quality to each Fund's other investments. Bank obligations may include
bankers' acceptances, negotiable certificates of deposit and non-negotiable time
deposits earning a specified return, issued for a definite period of time by a
U.S. bank that is a member of the Federal Reserve System or is insured by the
Federal Deposit Insurance Corporation, or by a savings and loan association or
savings bank that is insured by the Federal Deposit Insurance Corporation. Bank
obligations also include U.S. dollar-denominated obligations of foreign branches
of U.S. banks or of U.S. branches of foreign banks, all of the same type as
domestic bank obligations. Investments in bank obligations are limited to the
obligations of financial institutions having more than $1 billion in total
assets at the time of purchase. Investments by a Fund in non-negotiable time
deposits are limited to no more than 5% of its total assets at the time of
purchase.
 
U.S. TREASURY SECURITIES
 
Each Fund may invest in U.S. Treasury securities, including Treasury bills,
Treasury notes and Treasury bonds that differ in their interest rates,
maturities and times of issuance. Treasury bills have initial maturities of one
year or less; Treasury notes have initial maturities of one to ten years; and
Treasury bonds generally have initial maturities of greater than ten years.
 
                                        8
<PAGE>   12
 
U.S. GOVERNMENT SECURITIES
 
In addition to U.S. Treasury securities, each fund may invest in U.S. Government
securities, including securities issued or guaranteed by the U.S. Government or
its agencies or instrumentalities. Some obligations issued or guaranteed by U.S.
Government agencies and instrumentalities, for example, Government National
Mortgage Association pass-through certificates, are supported by the full faith
and credit of the U.S. Treasury; others, such as those of the Federal Home Loan
Banks, by the right of the issuer to borrow from the Treasury; others, such as
those issued by the Federal National Mortgage Association, by discretionary
authority of the U.S. Government to purchase certain obligations of the agency
or instrumentality; and others, such as those issued by the Student Loan
Marketing Association, only by the credit of the agency or instrumentality.
These securities bear fixed, floating or variable rates of interest. Principal
and interest may fluctuate based on generally recognized reference rates or the
relationship of rates. While the U.S. Government provides financial support to
such U.S. Government-sponsored agencies or instrumentalities, no assurance can
be given that it will always do so, since it is not so obligated by law.
 
ILLIQUID SECURITIES
 
No Fund will invest more than 10% of the value of its net assets in securities
that are illiquid because of restrictions on transferability or other reasons.
Repurchase agreements with deemed maturities in excess of seven days and
securities that are not registered under the Securities Act of 1933 (the "1933
Act") but that may be purchased by institutional buyers pursuant to Rule 144A
under the 1933 Act are subject to this 10% limit. Rule 144A allows for a broader
institutional trading market for securities otherwise subject to restriction on
resale to the general public by establishing a "safe harbor" from the
registration requirements of the 1933 Act for resales of certain securities to
qualified institutional buyers.
 
AMERICAN DEPOSITORY RECEIPTS ("ADRS")
 
Investments in ADRs by FIRST MUTUAL FUND and EMERGING GROWTH FUND are subject to
special investment risks that differ in some respects from those related to
investments in securities of U.S. domestic issuers. Such risks include potential
political, social or economic instability in the country of the issuer, the
difficulty of predicting international trade patterns, the possibility of the
imposition of exchange controls, expropriation, limits on removal of currency or
other assets, nationalization of assets, foreign withholding and income
taxation, and foreign trading practices (including higher trading commissions,
custodial charges and delayed settlements). Such securities may be subject to
greater fluctuations in price than securities issued by United States
corporations or issued or guaranteed by the U.S. Government, its agencies or
instrumentalities. The markets on which such securities trade may have less
volume and liquidity, and may be more volatile, than securities markets in the
United States. In addition, there may be less publicly available information
about a foreign company than about a U.S. domiciled company. Foreign companies
generally are not subject to uniform accounting, auditing and financial
reporting standards comparable to those applicable to domestic companies. There
is generally less government regulation of securities exchanges, brokers and
listed companies abroad than in the United States. Confiscatory taxation or
diplomatic developments could also affect investment in those countries. In
addition, foreign branches of U.S. banks, foreign banks and foreign issuers may
be subject to less stringent reserve requirements and to different accounting,
auditing, reporting, and recordkeeping standards than those applicable to
domestic branches of U.S. banks and domestic issuers.
 
For many foreign securities, U.S. dollar-denominated ADRs, which are traded in
the United States on exchanges or over-the-counter, are issued by domestic
banks. ADRs represent the right to receive securities of foreign issuers
deposited in a domestic bank or a correspondent bank. ADRs do not eliminate the
risk inherent in investing in the securities of foreign issuers. However, by
investing in ADRs rather than directly in stock of foreign issuers, a Fund can
avoid currency risks during the settlement period for either purchases or sales.
In general, there is a large, liquid market in the United States for many ADRs.
The information available for ADRs is subject to the accounting, auditing and
financial reporting standards of the domestic market or exchange on which they
are traded, whose standards are
 
                                        9
<PAGE>   13
 
more uniform and more exacting than those to which many foreign issuers may be
subject. The Funds may also invest in European Depository Receipts, or EDRs,
which are receipts evidencing an arrangement with a European bank similar to
that for ADRs and are designed for use in the European securities markets.
 
Certain ADRs and EDRs, typically those denominated as unsponsored, require the
holders thereof to bear most of the costs of such facilities while issuers of
sponsored facilities normally pay more of the costs thereof. The depository of
an unsponsored facility frequently is under no obligation to distribute
shareholder communications received from the issuer of the deposited securities
or to pass through the voting rights to facility holders in respect to the
deposited securities, whereas the depository of a sponsored facility typically
distributes shareholder communications and passes through the voting rights.
 
CONVERTIBLE SECURITIES
 
FIRST MUTUAL FUND and TOTAL RETURN BOND FUND may purchase convertible
securities, which are fixed-income securities, such as bonds or preferred stock,
which may be converted at a stated price within a specified period of time into
a specified number of shares of common stock of the same or a different issuer.
Convertible securities are senior to common stock in a corporation's capital
structure, but usually are subordinated to non-convertible debt securities.
While providing a fixed-income stream (generally higher in yield than the income
derivable from a common stock but lower than that afforded by a non-convertible
debt security), a convertible security also affords an investor the opportunity,
through its conversion feature, to participate in the capital appreciation of
the common stock into which it is convertible.
 
The Funds also may invest in debt securities with warrants attached or in units
with warrants. A warrant is an instrument issued by a corporation which gives
the holder the right to subscribe to a specified amount of the corporation's
capital stock at a set price for a specified period of time.
 
In connection with its purchases of convertible securities (which include debt
securities with warrants), the Funds from time to time may hold common stock
received upon the conversion of the security or the exercise of the warrant. The
Fund does not intend to retain the common stock in its portfolio and will sell
it as promptly as it can and in a manner which it believes will reduce the risk
of loss in connection with the sale.
 
In general, the market value of a convertible security is the higher of its
"investment value" (i.e., its value as a fixed-income security) or its
"conversion value" (i.e., the value of the underlying shares of common stock if
the security is converted). As a fixed-income security, the market value of a
convertible security generally increases when interest rates decline and
generally decreases when interest rates rise. However, the price of a
convertible security also is influenced by the market value of the security's
underlying common stock. Thus, the price of a convertible security generally
increases as the market value of the underlying stock increases, and generally
decreases as the market value of the underlying stock declines. Investments in
convertible securities generally entail less risk than investments in the common
stock of the same issuer.
 
FIXED-INCOME SECURITIES
 
Investors in the TOTAL RETURN BOND FUND should be aware that even though
interest-bearing securities are investments which promise a stable stream of
income, the prices of such securities typically are inversely affected by
changes in interest rates and, therefore, are subject to the risk of market
price fluctuations. Thus, if interest rates have increased from the time a
security was purchased, such security, if sold, might be sold at a price less
than its cost. Similarly, if interest rates have declined from the time a
security was purchased, such security, if sold, might be sold at a price greater
than its cost. In either instance, if the security was purchased at face value
and held to maturity, no gain or loss would be realized. Certain securities
purchased by the Fund, such as those with interest rates that fluctuate directly
or indirectly based on multiples of a stated index, are designed to be highly
sensitive to changes in interest rates and can subject the holders thereof to
extreme reductions of yield and possibly loss of principal.
 
The values of fixed-income securities also may be affected by changes in the
credit rating or financial condition of the issuing entities. Once the rating of
a security purchased by the Fund has been adversely changed, the
 
                                       10
<PAGE>   14
 
Fund will consider all circumstances deemed relevant in determining whether to
continue to hold the security. Holding such securities that have been downgraded
below investment-grade can subject the Fund to additional risk. Certain
securities purchased by the Fund, such as those rated "Baa" by Moody's or "BBB"
by S&P, Fitch or Duff, may be subject to such risk with respect to the issuing
entity and to greater market fluctuations than certain lower yielding, higher
rated fixed-income securities. Debt securities which are rated "Baa" by Moody's
are considered medium-grade obligations; they are neither highly protected nor
poorly secured, and are considered by Moody's to have speculative
characteristics. Debt securities rated "BBB" by S&P are regarded as having
adequate capacity to pay interest and repay principal, and while such debt
securities ordinarily exhibit 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 securities in this
category than in higher rated categories. Fitch considers the obligor's ability
to pay interest and repay principal on debt securities rated "BBB" to be
adequate; adverse changes in economic conditions and circumstances, however, are
more likely to have an adverse impact on these debt securities and, therefore,
impair timely payment. Debt securities rated "BBB" by Duff is considered to have
below average protection factors but may still be considered sufficient for
prudent investment.
 
FORWARD COMMITMENTS
 
The TOTAL RETURN BOND FUND may purchase securities on a when-issued or forward
commitment basis, which means that the price is fixed at the time of commitment,
but delivery and payment ordinarily take place a number of days after the date
of the commitment to purchase. The Fund will make commitments to purchase such
securities only with the intention of actually acquiring the securities, but the
Fund may sell these securities before the settlement date if it is deemed
advisable. The Fund will not accrue income in respect of a security purchased on
a when-issued or forward commitment basis prior to its stated delivery date.
 
Securities purchased on a when-issued or forward commitment basis and certain
other securities held by the Fund are subject to changes in value (both
generally changing in the same way, i.e., appreciating when interest rates
decline and depreciating when interest rates rise) based upon the public's
perception of the creditworthiness of the issuer and changes, real or
anticipated, in the level of interest rates. Such securities may expose the Fund
to risk because they may experience fluctuations in value prior to their actual
delivery. Purchasing debt securities on a when-issued or forward commitment
basis can involve the additional risk that the yield available in the market
when the delivery takes place actually may be higher than that obtained in the
transaction itself. A segregated account of the Fund consisting of cash, cash
equivalents or U.S. Government securities or other high-quality liquid debt
securities of the type in which the Fund invests at least equal at all times to
the amount of the when-issued or forward commitments will be established and
maintained at the Fund's custodian bank.
 
MORTGAGE-RELATED SECURITIES
 
Mortgage-related securities which may be purchases by the TOTAL RETURN BOND FUND
are securities collateralized by pools of mortgage loans assembled for sale to
investors by various governmental agencies, such as the Government National
Mortgage Association and government-related organizations such as the Federal
National Mortgage Association and the Federal Home Loan Mortgage Corporation, as
well as by private issuers such as commercial banks, savings and loan
institutions, mortgage banks and private mortgage insurance companies, and
similar foreign entities. The mortgage-related securities in which the Fund may
invest include those with fixed, floating and variable interest rates, those
with interest rates that change based on multiples of changes in interest rates
and those with interest rates that change inversely to changes in interest
rates, as well as stripped mortgage-backed securities which are derivative
multi-class mortgage securities. Stripped mortgage-backed securities usually are
structured with two classes that receive different proportions of interest and
principal distributions on a pool of mortgage-backed securities or whole loans.
A common type of stripped mortgage-backed security will have one class receiving
some of the interest and most of the principal from the mortgage collateral,
while the other class will receive most of the interest and the remainder of the
principal. In the most
 
                                       11
<PAGE>   15
 
extreme case, one class will receive all of the interest (the interest-only or
"IO" class), while the other class will receive all of the principal (the
principal-only or "PO" class). Although certain mortgage-related securities are
guaranteed by a third party or otherwise similarly secured, the market value of
the security, which may fluctuate, is not so secured. If the Fund purchases a
mortgage-related security at a premium, all or part of the premium may be lost
if there is a decline in the market value of the security, whether resulting
from changes in interest rates or prepayments in the underlying mortgage
collateral. As with other interest-bearing securities, the prices of certain of
these securities are inversely affected by changes in interest rates. However,
though the value of a mortgage-related security may decline when interest rates
rise, the converse is not necessarily true, since in periods of declining
interest rates the mortgages underlying the security are more likely to prepay.
For this and other reasons, a mortgage-related security's stated maturity may be
shortened by unscheduled prepayments on the underlying mortgages, and therefore,
it is not possible to predict accurately the security's return to the Fund.
Moreover, with respect to stripped mortgage-backed securities, if the underlying
mortgage securities experience greater than anticipated prepayments of
principal, the Fund may fail to fully recoup its initial investment in these
securities even if the securities are rated in the highest rating category by a
nationally recognized statistical rating organization. In addition, regular
payments received in respect of mortgage-related securities include both
interest and principal. No assurance can be given as to the return the Fund will
receive when these amounts are reinvested.
 
No assurance can be given as to the liquidity of the market for certain
mortgage-backed securities, such as collateralized mortgage obligations and
stripped mortgage-backed securities. Determination as to the liquidity of
interest-only and principal-only fixed mortgage-backed securities issued by the
U.S. Government or its agencies and instrumentalities will be made in accordance
with guidelines established by the Fund's Board of Trustees. In accordance with
such guidelines, the Advisor will monitor investments in such securities with
particular regard to trading activity, availability of reliable price
information and other relevant information. The Fund intends to treat other
stripped mortgage-backed securities as illiquid securities.
 
ASSET-BACKED SECURITIES
 
The TOTAL RETURN BOND FUND may invest in asset-backed securities. The
securitization techniques used for asset-backed securities are similar to those
used for mortgage-related securities. These securities include debt securities
and securities with debt-like characteristics. The collateral for these
securities has included home equity loans, automobile and credit card
receivables, boat loans, computer leases, airplane leases, mobile home loans,
recreational vehicle loans and hospital account receivables.
 
Asset-backed securities present certain risks that are not presented by
mortgage-backed securities. Primarily, these securities do not have the benefit
of the same security interest in the related collateral. Credit card receivables
generally are unsecured and the debtors are entitled to the protection of a
number of state and federal consumer credit laws, many of which give such
debtors the right to set off certain amounts owed on the credit cards, thereby
reducing the balance due. Most issuers of asset-backed securities backed by
automobile receivables permit the services of such receivables to retain
possession of the underlying obligations. If the servicer were to sell these
obligations to another party, there is a risk that the purchaser would acquire
an interest superior to that of the holders of the related asset-backed
securities. In addition, because of the large number of vehicles involved in a
typical issuance and technical requirements under state laws, the trustee for
the holders of asset-backed securities backed by automobile receivables may not
have a proper security interest in all of the obligations backing such
receivables. Therefore, there is the possibility that recoveries on repossessed
collateral may not, in some cases, be available to support payments on these
securities.
 
MUNICIPAL OBLIGATIONS
 
The TOTAL RETURN BOND FUND may invest in Municipal obligations, which are debt
obligations issued by states, territories and possessions of the United States
and the District of Columbia and their political subdivisions, agencies and
instrumentalities, or multistate agencies or
 
                                       12
<PAGE>   16
 
authorities. While in general, municipal obligations are tax exempt securities
having relatively low yields as compared to taxable, non-municipal obligations
of similar quality, certain issues of municipal obligations, both taxable and
non-taxable, offer yields comparable and in some cases greater than the yields
available on other permissible investments. Municipal obligations generally
include debt obligations issued to obtain funds for various public purposes as
well as certain industrial development bonds issued by or on behalf of public
authorities.
 
Municipal obligations are classified as general obligation bonds, revenue bonds
and notes. General obligation bonds are secured by the issuer's pledge of its
faith, credit and taxing power for the payment of principal and interest.
Revenue bonds are payable from the revenue derived from a particular facility or
class of facilities or, in some cases, from the proceeds of a special excise or
other specific revenue source, but not from the general taxing power. Tax-exempt
industrial development bonds, in most cases, are revenue bonds and generally do
not carry the pledge of the credit of the issuing municipality, but generally
are guaranteed by the corporate entity on whose behalf they are issued.
 
Dividends received by shareholders which are attributable to interest income
received by it from municipal obligations generally will be subject to Federal
income tax. Municipal obligations bear fixed, floating or variable rates of
interest, which are determined in some instances by formulas under which the
municipal obligation's interest rate will change directly or inversely to
changes in interest rates or an index, or multiples thereof, in many cases
subject to a maximum and minimum. The Fund currently intends to invest no more
than 25% of its assets in municipal obligations. However, this percentage may be
varied from time to time without shareholder approval.
 
ZERO COUPON AND STRIPPED SECURITIES
 
The TOTAL RETURN BOND FUND may invest in zero coupon U.S. Treasury securities,
which are Treasury notes and bonds that have been stripped of their unmatured
interest coupons, the coupons themselves and receipts or certificates
representing interests in such stripped debt obligations and coupons. The Fund
also may invest in zero coupon securities issued by corporations and financial
institutions which constitute a proportionate ownership of the issuer's pool of
underlying U.S. Treasury securities. A zero coupon security pays no interest to
its holder during its life and is sold at a discount to its face value at
maturity. The amount of the discount fluctuates with the market price of the
security. The market prices of zero coupon securities generally are more
volatile than the market prices of securities that pay interest periodically and
are likely to respond to a greater degree to changes in interest rates than
non-zero coupon securities having similar maturities and credit qualities.
 
Federal income tax law requires the holder of a zero coupon security or of
certain pay-in-kind bonds to accrue income with respect to these securities
prior to the receipt of cash payments. If the Fund invests in such securities it
may be required, in order to maintain its qualification as a regulated
investment company and avoid liability for Federal income taxes, to distribute
the income accrued with respect to these securities and may have to dispose of
portfolio securities under disadvantageous circumstances in order to generate
cash to satisfy these distribution requirements.
 
FOREIGN GOVERNMENT OBLIGATIONS; SECURITIES OF SUPRANATIONAL ENTITIES
 
The TOTAL RETURN BOND FUND may invest in U.S. dollar denominated obligations
issued or guaranteed by one or more foreign governments or any of their
political subdivisions, agencies or instrumentalities that are determined by the
Advisor to be of comparable quality to the other obligations in which the Fund
may invest. Such securities also include debt obligations of supranational
entities. Supranational entities include international organizations designated
or supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the World Bank), the European Coal and Steel Community, the Asian
Development Bank and the InterAmerican Development Bank. The percentage of the
Fund's assets invested in securities issued by foreign governments will vary
depending on the relative yields of such securities, the economic and financial
markets of the countries in
 
                                       13
<PAGE>   17
 
which the investments are made and the interest rate climate of such countries.
 
OTHER FOREIGN SECURITIES
 
The TOTAL RETURN BOND FUND may invest in U.S. dollar denominated obligations of
foreign corporations. Investing in securities issued by foreign corporations
involves considerations and possible risks not typically associated with
investing in obligations issued by domestic corporations. Less information may
be available about foreign companies than about domestic companies, and foreign
companies generally are not subject to the same uniform accounting, auditing and
financial reporting standards or to other regulatory practices and requirements
comparable to those applicable to domestic companies.
 
The risks associated with investing in foreign securities are often heightened
by investments in developing or emerging markets. Investments in emerging or
developing markets involve exposure to economic structures that are generally
less diverse and mature and to political systems which can be expected to have
less stability, than those of more developed countries. Moreover, the economies
of individual emerging market countries may differ favorably or unfavorably from
the U.S. economy in such respects as the rate of growth in gross domestic
product, the rate of inflation, capital reinvestment, resource self-sufficiency
and balance of payments position.
 
                            MANAGEMENT OF THE TRUST
 
BOARD OF TRUSTEES
 
Under Delaware law, the business and affairs of the Trust are managed under the
direction of the Board of Trustees. There are currently eight Trustees, five of
whom are not "interested persons" of the Trust within the meaning of that term
under the Act. The Trustees, in turn, elect the officers of the Trust to
supervise actively its day-to-day operations. The Statement of Additional
Information contains the name and background information regarding each Trustee.
 
INVESTMENT ADVISOR
 
Trainer, Wortham & Co., Inc. (the "Advisor"), with offices at 845 Third Avenue,
New York, NY 10022 is the Trust's Investment Advisor and manager and is
registered as an investment adviser under the Investment Advisers Act of 1940,
as amended.
 
The Advisor, organized in 1990, continues an investment counseling business
which began in 1924 as Trainer & Associates. The Advisor supervises
approximately $2.3 billion in investment accounts and is owned entirely by the
officers active in the day-to-day management of portfolios. By reason of his
ownership of 32% of the Advisor's stock, Charles V. Moore may be said to be a
"controlling person" of that firm.
 
Pursuant to an Investment Advisory Agreement with the Trust on behalf of FIRST
MUTUAL FUND, the Advisor receives an annual fee, accrued daily and paid monthly,
of 0.75% of the Funds' average daily net assets.
 
   
Pursuant to the Investment Advisory Agreement with the Trust on behalf of
EMERGING GROWTH FUND, the Advisor receives an annual fee, accrued daily and paid
monthly, of 1.25% of the Fund's average daily net assets. From time to time, the
Advisor may waive receipt of these fees and/or voluntarily assume certain Fund
expenses, which would have the effect of lowering the Fund's expense ratio and
increasing the yield to investors at the time such amounts are waived or
assumed, as the case may be. The Fund will not reimburse the Advisor at a later
time for the expenses assumed.

<PAGE>   18
 
with respect to and places orders for all purchases and sales of the portfolio
securities. The President of the Trust, David P. Como, has been primarily
responsible for the day-to-day investment management of First Mutual Fund's
portfolio since 1982. Mr. Como has been a Managing Director of the Advisor since
September 1990, and was Managing Director and Vice President of BIL, Trainer,
Wortham & Co., its predecessor company, from 1988 through September 1990.
 
Robert R. Douglass, Jr. is the Vice-President and Portfolio Manager of the
Emerging Growth Fund. Mr. Douglass has been a Managing Director of the Advisor
since August, 1994. Prior to August, 1994, Mr. Douglass served as Assistant
Vice-President at Warburg, Pincus Cousellors, Inc.
 
   
John D. Knox is the Vice-President and Portfolio Manager of the TOTAL RETURN
BOND FUND. Mr. Knox joined Trainer Wortham in December, 1995 as the Managing
Director of Fixed Income. Prior to joining Trainer Wortham, Mr. Knox served as
Director of Global Fixed Income and Managing Director from 1994-1995 for Bear
Sterns Asset Management and Bear Stearns, respectively. For more than 11 years
prior thereto, Mr. Knox was a Principal and Senior Portfolio Manager at Morgan
Stanley Asset Management where he managed fixed income portfolios for a variety
of domestic and international clients.
    
 
ADMINISTRATOR
 
The Trust, on behalf of the Funds, has entered into an administrative services
agreement dated July 25, 1996, (the "Administration Agreement") with FPS
Services, Inc. ("FPS"), 3200 Horizon Drive, P.O. Box 61503, King of Prussia, PA
19406-0903, pursuant to which the Administrator receives a fee accrued daily and
paid monthly of 0.15% of the value of each Fund's first $50 million of total
average net assets; 0.10% of the value of each Fund's next $50 million of total
average net assets; and 0.05% of the value of each Fund's total average net
assets in excess of $100 million, subject to an annual minimum fee of $72,000
for the Trust.
 
The term of the Administration Agreement is two years and shall continue in
force each year thereafter, so long as such continuance is approved (i) by FPS;
(ii) by vote, cast in person at a meeting called for the purpose, of a majority
of the Board of Trustees who are not parties to the Administration Agreement or
interested persons (as defined in the Act ) of any such party, and (iii) by vote
of a majority of the Board of Trustees or a majority of the Funds' outstanding
voting securities. The Trust and FPS may terminate the Administration Agreement
at any time without penalty upon giving the other party 120 days written notice.
The Administration Agreement shall automatically terminate in the event of its
assignment.
 
The services FPS provides to the Funds include: coordinating and monitoring of
any third parties furnishing services; providing the necessary office space,
equipment and personnel to perform administrative and clerical functions;
preparing, filing and distributing of proxy materials, periodic reports to
shareholders, registration statements and other documents; organizing of board
meetings; and responding to shareholder inquiries.
 
DISTRIBUTOR
 
FPS Broker Services, Inc. ("FPSB") serves as the Funds' Distributor on a best
efforts basis. FPSB is an affiliated company of FPS inasmuch as both are under
common ownership.
 
TRANSFER AGENT AND ACCOUNTING SERVICES AGENT
 
FPS also serves as the Funds' Transfer Agent, Dividend Disbursing Agent,
Redemption Agent and Accounting Services Agent. In such capacities, FPS is
responsible for providing record-keeping and administrative services (including
calculation of net asset value) and for processing share purchases and
redemptions. Correspondence relating to purchases and redemptions of Fund
shares, or to dividend payments or reinvestment, should be addressed to FPS
Services, Inc.
 
CUSTODIAN
 
UMB Bank, n.a., Kansas City, Missouri, is Custodian for the securities and cash
of the Funds.
 
                               DISTRIBUTION PLAN
 
The shareholders of the FIRST MUTUAL FUND and EMERGING GROWTH FUND have each
adopted a Plan of Distribution (the "Plan(s)"), effective October 31, 1991 and
 
                                       15
<PAGE>   19
 
   
July 25, 1996, respectively, pursuant to Rule 12b-1 under the Act. The Plans
were last approved by the Board of Trustees on October 21, 1997. The maximum
amount payable by EMERGING GROWTH FUND was decreased from 0.50% to 0.25% by
unanimous vote of the Board of Trustees at such meeting. Each Plan permits the
Fund to pay certain expenses associated with the distribution of its shares. The
Plans provide that the Funds will reimburse FPSB for actual distribution and
shareholder servicing expenses incurred by FPSB not exceeding, on an annual
basis, 0.25% of each Fund's average daily net assets. Amounts expended by FPSB,
but not reimbursed by the Funds, in any year will not be a continuing liability
of the Funds in subsequent years. Because each Fund reimburses FPSB only for
actual expenditures, FPSB realizes no profit from the Plans. The Plans may be
terminated by either party at any time and the Funds shall have no liability for
expenses that were not reimbursed as of the date of termination.
    
 
   
All such payments made pursuant to the Plans shall be made for the purpose of
promoting the sale of shares or other such distribution related expenses,
including any distribution or service fees paid to securities dealers,
investment advisors, financial planners, and others, who have executed a
distribution agreement with FPSB. Distribution expenses which are attributable
to a particular Fund will be charged against that Fund's assets. Distribution
expenses which are attributable to more than one Fund will be allocated among
the Funds in proportion to their relative net assets.
    
 
                                   BROKERAGE
 
The Advisor will attempt to place portfolio transactions for the Funds with
those brokers and dealers who will execute orders in an effective manner at the
most favorable price. When the execution and price offered by two or more
brokers or dealers are comparable, the Advisor may, in its discretion, purchase
and sell portfolio securities to and from brokers and dealers who provide
research advice and other services. The Advisor may give consideration to the
sale of shares of the Funds as a factor in the selection of brokers and dealers
to execute portfolio transactions subject to seeking best price and execution.
The Funds may pay brokerage commissions to brokers which are affiliated with
Officers and Trustees of the Funds, provided that such transactions are in
compliance with Section 17(e)(2) of the Act.
 
PORTFOLIO TURNOVER
 
   
The rate of portfolio turnover will depend on the investment strategy
implemented by the Advisor for the Funds which will vary over any given time
period, but may be influenced by the following: general market conditions;
valuation analysis; market volatility; and technical analysis. It is not the
policy of the Funds to invest with the goal of generating short-term trading
profits, rather the Funds seek to generate long-term capital appreciation when
possible by holding investments over a full market cycle, normally 2-3 years. It
is anticipated that the Funds' investment objectives and strategies will result
in a portfolio turnover rate of less than 100%, except for FIRST MUTUAL FUND
which is not expected to exceed 150% over the course of a fiscal year; however
market conditions may cause turnover to exceed 150% in certain years. The
portfolio turnover rates of FIRST MUTUAL FUND for the fiscal years ended June
30, 1997, 1996 and 1995 were 109%,107 and 198%, respectively. The portfolio
turnover rates of EMERGING GROWTH FUND and TOTAL RETURN BOND FUND for their
initial fiscal period ended June 30, 1997 were 50% and 112%, respectively. High
portfolio turnover involves correspondingly greater brokerage commissions and
other costs, which are borne directly by the Funds.
    
 
                               PURCHASE OF SHARES
 
Shares are offered for sale by the Funds on a continuous basis at each Fund's
net asset value. Purchasers of the Funds shares pay no "sales load" or
underwriting commission, although broker-dealers effecting purchases or sales of
Fund shares for their customers may charge a service fee in connection
therewith. The minimum initial investment in a Fund is $250.00. Existing
shareholders may purchase additional shares with a minimum purchase of $50 per
transaction.
 
Purchases of the Funds are made at the net asset value per share next determined
after receipt by FPS as Transfer Agent of a purchase order in good order. Thus,
for orders received in good order before 4:00 p.m. (Eastern time), the public
offering price will be the net
 
                                       16
<PAGE>   20
 
asset value determined as of 4:00 p.m. (Eastern time) that day. Orders for Fund
shares received after 4:00 p.m. (Eastern time) will be purchased at the next
determined net asset value on the business day following receipt of the order.
 
INVESTING BY TELEPHONE
 
The Funds may accept telephone orders from broker-dealers or service
organizations which have been previously approved by the Trust. It is the
responsibility of such broker-dealers or service organizations to promptly
forward purchase orders and payments for same to the Funds. Shares of the Funds
may be purchased through broker-dealers, banks and bank trust departments which
may charge the investor a transaction fee or other fee for their services at the
time of purchase. Such fees would not otherwise be charged if the shares were
purchased directly from the Funds.
 
INVESTING BY MAIL
 
Prospective shareholders may purchase shares of the Funds by completing and
signing the "Investment Application" enclosed with this Prospectus and sending
the application, together with a check payable to, "NAME OF FUND", c/o FPS
Services, Inc., 3200 Horizon Drive, P.O. Box 61503, King of Prussia, PA
19406-0903. Except as noted below, purchases without full payment will not be
processed until payment is received. The ownership of shares shall be recorded
on the books of the Transfer Agent in an account under the shareholder's name. A
confirmation of the purchase will be issued showing the account number and
number of shares owned.
 
INVESTING BY WIRE
 
Shares may also be purchased by instructing the bank to wire Federal Funds to
the Transfer Agent. Federal Funds are monies of member banks within the Federal
Reserve System. The bank must include the full name(s) in which the account is
registered and the Fund account number, and should address its wire as follows:
 
                                 UMB BANK KC NA
                               ABA # 10-10-00695

                               A/C 98-7037-071-9
                            FBO "FIRST MUTUAL FUND,"
                    "TRAINER, WORTHAM EMERGING GROWTH FUND"
                                       OR
                   "TRAINER, WORTHAM TOTAL RETURN BOND FUND"
               Account of (exact name(s) of account registration)
                        Shareholder Account #
 
When opening a new account by wire transfer, first telephone the Transfer Agent
at 800-441-6580 to request an account number and furnish the respective Fund
with a social security or other tax identification number. A completed
application with signature(s) of registrant(s) must be filed with the Transfer
Agent immediately subsequent to the initial wire. Federal Funds wires must be
made in amounts of $250 or more. The bank will generally charge a fee for this
wire. The Funds will not be responsible for the consequences of delays,
including delays in the banking or Federal Reserve wire systems.
 
SUBSEQUENT INVESTMENTS
 
Once a shareholder's account has been established, additional purchases may be
made by sending a check payable to "NAME OF FUND" c/o FPS Services, Inc., P.O.
Box 412797, Kansas City, MO 64141-2797. Please enclose the stub of the account
statement and include the Fund account number on the check (as well as the
attributable year for retirement plan investments, if applicable). Additional
purchases may also be made through an Automatic Investment Plan which provides
shareholders a convenient method to make regularly scheduled subsequent
investments. See "SHAREHOLDER SERVICES."
 
                              REDEMPTION OF SHARES
 
IN GENERAL
 
The Trust will make your redemption proceeds available as promptly as possible
and, in any event, within seven business days after your redemption order, in
proper order, is received. For your redemption order to be in proper order, your
order must include name as it appears on your account, your account number and a
signature
 
                                       17
<PAGE>   21
 
guarantee as required as described below. However, your redemption proceeds may
be delayed if you purchased the shares to be redeemed by check (including
certified or cashier checks) until such check has cleared and the Trust has
collected good funds for your purchase. Such collection may take 15 days or
more.
 
REDEMPTIONS BY WRITTEN REQUEST
 
Shareholders may redeem shares by mail by writing directly to the Transfer Agent
at FPS Services, Inc., 3200 Horizon Drive, P.O. Box 61503, King of Prussia, PA
19406-0903, and requesting liquidation of all or any part of their shares. The
redemption request must be signed exactly as the shareholder's name appears on
the form of registration and must include the Fund's account number. If shares
are owned by more than one person, the redemption request must be signed by all
owners exactly as their names appear in the registration. Shares registered in
the name of corporations, trusts and fiduciaries can be redeemed only upon
instructions of a duly authorized person. To protect the account, the Transfer
Agent and the Funds from fraud, signature guarantees are required for certain
redemptions. Signature guarantees are required for: (1) all redemptions of
$25,000 or more; (2) any redemptions if the proceeds are to be paid to someone
other than the person(s) or organization in whose name the account is
registered; (3) any redemptions which request that the proceeds be wired to a
bank (unless bank information was received at the time the account was
established); and (4) requests to transfer the registration of shares to another
owner. The Transfer Agent requires that signatures be guaranteed by an "eligible
guarantor institution" as defined in Rule 17Ad-15 under the Securities Exchange
Act of 1934. Eligible guarantor institutions include banks, broker-dealers,
credit unions, national securities exchanges, registered securities
associations, clearing agencies and savings associations. Broker-dealers
guaranteeing signatures must be a member of a clearing corporation or maintain
net capital of at least $100,000. Credit unions must be authorized to issue
signature guarantees. Signature guarantees will be accepted from any eligible
guarantor institution which participates in a signature guarantee program. The
Transfer Agent cannot accept guarantees from notaries public. The Transfer Agent
may require additional supporting documents for redemptions made by
corporations, executors, administrators, trustees and guardians.
 
Shares will be redeemed at the net asset value, next determined after receipt of
a redemption request in proper form. Moreover, under the Act, the right of
redemption may be suspended when (a) trading on the New York Stock Exchange is
restricted or such Exchange is closed for other than weekends or holidays, (b)
the Securities and Exchange Commission has by order permitted such suspension,
or (c) an emergency exists making disposal of portfolio securities or valuation
of net assets not reasonably practicable. When in the opinion of the Board of
Trustees, conditions exist which make payments in cash on redemption unwise or
undesirable, the Funds may make payment of redemption in securities.
 
The value of a shareholder's shares upon redemption may be more or less than
their cost depending upon the value of a Fund's portfolio securities at the time
of redemption.
 
REDEMPTIONS BY TELEPHONE
 
Shareholders who have so indicated on the application, or have subsequently
arranged in writing to do so, may redeem shares by instructing the Transfer
Agent by telephone at (800) 441-6580.
 
In order to arrange for redemption by wire or telephone after an account has
been opened, or to change the bank or account designated to receive redemption
proceeds, a written request must be sent to the Transfer Agent at the address
listed under "Investing by Mail." Such requests must be signed by the
shareholder, with signatures guaranteed (see "Redemptions By Written Request"
for details regarding signature guarantees). Further documentation may be
requested from corporations, executors, administrators, trustees, or guardians.
 
The Funds reserve the right to refuse a wire or telephone redemption if it is
believed advisable to do so. Procedures for redeeming Fund shares by wire or
telephone may be modified or terminated at any time by the Funds. Neither the
Funds nor any of their service contractors will be liable for any loss or
expense in acting upon telephone instructions that are reasonably believed to be
genuine. In attempting to confirm that telephone instruc-
 
                                       18

tions are genuine, the Funds will use such procedures as are considered
reasonable, including requesting a shareholder to correctly state his or her
Fund account number, the name in which his or her account is registered, his or
her social security number, banking institution, bank account number, and the
name in which his or her bank account is registered. To the extent that the
Funds fail to use reasonable procedures to verify the genuineness of telephone
instructions, it and/or its service contractors may be liable for any such
instructions that prove to be fraudulent or unauthorized.
 
Shares of the Funds may be redeemed through certain broker-dealers, banks and
bank trust departments who may charge the investor a transaction fee or other
fee for their services at the time of redemption. Such fees would not otherwise
be charged if the shares were redeemed directly from the Funds.
 
                               EXCHANGE OF SHARES
 
You may exchange your shares of any Fund of the Trust for shares of either of
the other Fund at net asset value without the payment of any fee or charge in
writing or by telephone. An exchange is considered a sale of shares and may
result in capital gain or loss for Federal income tax purposes. Before an
exchange can be made, you must have received the current Prospectus for the Fund
into which you wish to exchange, and the exchange privilege may be exercised
only in those states where shares of such Fund, as the case may be, may legally
be sold. If the Transfer Agent receives exchange instructions from you in
writing or by telephone at (800) 441-6580, in good order by the Valuation Time
on any Business Day, the exchange will be effected that day. For your exchange
request to be in good order, your request must include your name as it appears
on your account, your account number, the amount to be exchanged, the name of
the Funds from which and to which the exchange is to be made and a signature
guarantee as may be required. A written request by you for an exchange in excess
of $25,000 must be accompanied by a signature guarantee as described under
"Redemptions -- By Written Request."
 
                              SHAREHOLDER SERVICES
 
The following special services are available to shareholders. An investor may
change or stop these services at any time by written notice to the Funds.
 
AUTOMATIC INVESTMENT PLAN
 
The Funds have an Automatic Investment Plan which provides shareholders with a
convenient method by which investors may have amounts deducted directly from
their checking accounts for investment in a Fund. The minimum initial and
subsequent investments for the Funds also apply when using this method of
investing. To begin participating in this Plan, use the Automatic Investment
Plan Application found in the back of this Prospectus.
 
SYSTEMATIC CASH WITHDRAWAL PLAN
 
The Funds have a Systematic Withdrawal Plan, which provides for voluntary
automatic withdrawals of at least $50 monthly, quarterly, semi-annually or
annually. Shareholders who purchase or already own $5,000 or more of a Fund's
shares, valued at the current public offering price, and who wish to receive
periodic payments may establish a Systematic Withdrawal Plan. In order to
qualify for this option, dividends and capital gains must be reinvested.
 
RETIREMENT PLANS
 
The Funds have available certain Individual Retirement Accounts for use by
certain individuals who qualify (including earned income from self-employment).
More detailed information about how to participate in these IRA Plans, the fees
charged by the Custodian bank, and brochures containing other pertinent
information, may be obtained by contacting the Funds at (800) 257-4414.
 
   
The Taxpayers Relief Act which was signed into law on August 5, 1997, impacts
the traditional IRA and creates two additional types of IRAs.
 
Traditional (deductible) IRAs:
 
The Taxpayers Relief Act will gradually increase the adjusted gross income
phaseouts for deductible IRAs over the next ten years. Married individuals may
make deductible contributions even if spouses are active par-
 
                                       19
<PAGE>   23
 
ticipants in an employer-sponsored plan. The 10% early withdrawal tax will not
apply for up to $10,000 for first-time home purchases or education expenses.
 
Roth IRAs:
 
The Taxpayers Relief Act has created the new Roth IRA. While contributions to a
Roth IRA are not currently deductible, the amounts within the accounts
accumulate tax-free and qualified distributions will not be included in a
shareholder's taxable income. The contribution limit is $2,000 annually ($4,000
for joint returns) in aggregate with contributions to Traditional IRAs. Certain
income phaseouts apply.
 
Education IRAs:
 
The Taxpayers Relief Act has also created the new Education IRA. Like the Roth
IRA, contributions are non-deductible, but the investment earnings accumulate
tax-free, and distributions used for higher education expenses are not taxable.
Contributions limits are $500 per account and certain income phaseouts apply.
    
 
                                NET ASSET VALUE
 
The net asset value per share of capital stock of the Funds will be determined
each business day on which the New York Stock Exchange is open for business as
of the close of regular trading hours (currently 4:00 p.m. Eastern time) and for
any other day (other than a day on which no shares are tendered for redemption
and no order to purchase or sell any shares is received) during which there is a
sufficient degree of trading in the Funds' portfolio securities that the Funds'
net asset value per share might be materially affected. Determination of net
asset value will be in accordance with generally accepted accounting principles
and will be computed by dividing the value of each Fund's total net assets by
the total number of shares outstanding. Securities traded on a securities
exchange are valued at the last sale price prior to the time of computation or,
if there have been no sales on that day, at the mean of their closing bid and
asked prices. Securities not traded on a securities exchange but for which
market quotations are readily available will be valued at the mean of their bid
and asked prices, although securities traded over the counter on NASDAQ will be
valued at their last sale price. Securities not traded on a securities exchange
and other securities or assets for which market quotations are not readily
available will be valued at fair value as determined in good faith by the Board
of Trustees. Once the aggregate value of all securities has been determined,
there will be added to this total the dollar amount of cash on hand and
receivables and the value of all other assets. From the sum of the foregoing,
the aggregate amount of all liabilities and all accrued expenses will be
deducted to produce the total net asset value of all shares outstanding.
 
                              DIVIDENDS AND TAXES
 
Each Fund intends to distribute substantially all of its net investment income
and net capital gains. FIRST MUTUAL FUND and EMERGING GROWTH FUND intend to
distribute their net investment income at least annually and to distribute their
net capital gains, if any, at least annually. Dividends, if any, from net
investment income will be declared and paid quarterly by the TOTAL RETURN BOND
FUND. Dividends from net investment income or net short-term capital gains will
be taxable to you, whether received in cash or in additional shares.
 
The Funds permit any shareholder located in states where the Funds' shares are
registered (regardless of the number of shares owned) to elect a Dividend
Reinvestment Plan for the automatic reinvestment of all distributions. If a
dividend is declared from net investment income or a capital gains distribution
is declared from net capital gains, investors electing under the Dividend
Reinvestment Plan are required to take such dividends or distribution in Fund
shares rather than in cash. The full amount of the distribution will be invested
and the shareholder will be credited with any full or fractional shares
resulting. The investment under the Dividend Reinvestment Plan will be made at
the current net asset value on the dividend payable date. Dividends and capital
gains distributions will result in a taxable event for the investor even though
invested in shares.
 
An investor may elect or terminate participation in the Dividend Reinvestment
Plan at any time. Elections to participate must be made using the Investment
Application. Termination can be made by written notice. Costs of the Plan will
be borne by the Funds. There is no
 
                                       20
<PAGE>   24
 
assurance that such Plan will result in a profit for an investor.
 
TAXES
 
Each Fund intends to qualify annually to be treated as a regulated investment
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"). As such, each Fund will not be subject to Federal income tax, or to any
excise tax, to the extent its earnings are distributed as provided in the Code
and by satisfying certain other requirements relating to the sources of its
income and diversification of its assets.
 
The TOTAL RETURN BOND FUND'S investment in certain bonds, such as zero coupon
bonds, may cause the Fund to recognize income and make distributions prior to
the receipt of cash payments. These bonds are subject to special tax rules
concerning the amount, character and timing of income required to be reported by
the Fund and distributed.
 
For corporate investors in the Funds, dividends from net investment income will
generally qualify in part for the corporate dividends-received deduction.
However, the portion of the dividends so qualified depends on the aggregate
qualifying dividend income received by the Funds from domestic (U.S.) sources.
 
Distributions paid by the Funds from capital gains, whether received in cash or
in additional shares, are taxable to investors as capital gains, regardless of
the length of time an investor has owned shares in the Fund. The Funds do not
seek to realize any particular amount of capital gains during a year; rather,
realized gains are a by-product of management activities. Consequently, capital
gains distributions may be expected to vary considerably from year to year.
Also, if purchases of shares in a Fund are made shortly before the record date
for a capital gains distribution or a dividend, a portion of the investment will
be returned as a taxable distribution.
 
Dividends which are declared in October, November or December to shareholders of
record in such a month but which, for operational reasons, may not be paid to
the shareholder until the following January, will be treated for tax purposes as
if paid by a Fund and received by the shareholder on December 31 of the calendar
year in which they are declared.
 
A sale or redemption of shares of a Fund is a taxable event and may result in a
capital gain or loss to shareholders subject to tax.
 
Each year, the Funds will mail information to shareholders on the tax status of
the Funds' dividends and distributions made to shareholders.
 
The Funds are required to withhold 31% of taxable dividends, capital gains
distributions, and redemptions paid to shareholders who have not complied with
IRS taxpayer identification regulations. You may avoid this withholding
requirement by certifying on your account registration form your proper taxpayer
identification number and by certifying that you are not subject to backup
withholding.
 
   
The Taxpayers Relief Act, which was signed into law on August 5, 1997, is the
most wide-ranging tax legislation since 1986. Several provisions therein will
impact the taxation of capital gains.
 
Change in Rates:
 
The Taxpayers Relief Act has lowered the tax rate for long-term capital gains
from 28% to 20%, but increases the holding period of the assets from more than
one year to more than eighteen months. For persons in the 15% income tax
bracket, the new rate is 10%.
 
Realized gains from capital assets held more than one year, but eighteen months
or less, will be taxed at a 28% rate. Such gains will be termed "mid-term"
capital gains.
 
Also, capital gains in property held for more than five years will be eligible
for an 18% tax rate, but this only applies to assets acquired after December 31,
2000; therefore, a shareholder will not benefit from this provision until the
year 2006.
    
 
The tax discussion set forth above is included for general information only.
Prospective investors should consult their own tax advisers concerning the
Federal, state, local or foreign tax consequences of an investment in the Funds.

                            PERFORMANCE INFORMATION
 
From time to time, performance information regarding the Funds, such as total
return, may be quoted in advertisements or in communications to shareholders.
These performance quotations represent a Fund's past performance, and should not
be considered as representative of future results. The Funds' total return may
be calculated on an average annual and/or aggregate basis for various periods
(which will be stated in all advertisements). Average annual total return
reflects the average percentage change per year in the value of an investment in
the Funds. Aggregate total return reflects the total percentage change over the
stated period. In calculating total return, the assumption is made that
dividends and capital gain distributions made by the Funds during the period are
reinvested in additional shares.
 
Total return of each Fund may be compared to: other mutual funds with similar
investment objectives; other relevant indices; rankings prepared by independent
services; and financial or industry publications and/or other publications or
services that monitor the performance of mutual funds, such as Lipper
Analytical, CDA/Weisenberger, the Investment Company Institute, Morningstar,
Inc., the Dow Jones Composite Average or its component indices and Standard &
Poor's 500 Stock Index or its component indices, among others.
 
   
The TOTAL RETURN BOND FUND may also advertize its yield. The Fund's yield is
calculated by dividing the net investment income per share earned during a
recent 30-day (or one month) period by the maximum public offering price per
share on the last day of the period.
    
 
The principal value of an investment in each Fund will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than their original
cost.
 
Graphs which compare the increase in value of a $10,000 investment in each Fund
with the performance of the its relevant Index and a discussion of performance
are included in the Funds' Annual Report dated June 30, 1997.
 
                              GENERAL INFORMATION
 
ORGANIZATION
 
Each Fund is a separate Series of shares of TRAINER, WORTHAM FIRST MUTUAL FUNDS,
a Delaware business trust organized pursuant to a Trust Instrument dated January
17, 1995. On October 1, 1996, the name of the Trust was changed from First
Mutual Funds to its present name. The Trust is registered under the Act as an
open-end management investment company commonly known as a mutual fund. The
Trustees of the Trust may establish additional series or classes of shares of
the Trust without the approval of shareholders. The assets of each Fund belong
only to that Fund, and the liabilities of each Fund are borne solely by that
Fund and no other.
 
DESCRIPTION OF SHARES
 
   
Each Fund is authorized to issue an unlimited number of shares of beneficial
interest with a par value of $0.001 per share. Shares of each Fund represent
equal proportionate interests in the assets of the Fund only and have identical
voting, dividend, redemption, liquidation and other rights. All shares issued
are fully paid and non-assessable, and shareholders have no preemptive or other
right to subscribe to any additional shares. Currently, there is only one class
of shares issued by the Funds.
    
 
SHAREHOLDER MEETINGS
 
The Board of Trustees do not intend to hold annual meetings of shareholders of
the Funds. The Board of Trustees has undertaken to the Securities and Exchange
Commission, however, that they will promptly call a meeting for the purpose of
voting upon the question of removal of any Trustee when requested to do so by
holders of not less than 10% of the outstanding shares of the Fund. In addition,
subject to certain conditions, shareholders of the Funds may apply to the Funds
to communicate with other shareholders to request a shareholder's meeting to
vote upon the removal of a Trustee or Trustees.
 
CERTAIN PROVISIONS OF TRUST INSTRUMENT
 
Under Delaware law, the shareholders of the Funds will not be personally liable
for the obligations of the Trust; a
 
                                       22
<PAGE>   26
 
shareholder is entitled to the same limitation of personal liability extended to
shareholders of corporations.

Shareholders will receive annual financial statements which are audited by the
Funds' independent accountants, Briggs, Bunting and Dougherty, LLP as well as
unaudited semi-annual financial statements. Shareholder inquiries should be

                       TRAINER, WORTHAM FIRST MUTUAL FUNDS

   
Trainer, Wortham First Mutual Funds (the "Trust"), 845 Third Avenue, 6th Floor,
New York, NY 10022, is an open-end management investment company, which 
currently offers shares of the following three Funds, each with its own
investment objectives and policies: FIRST MUTUAL FUND; TRAINER, WORTHAM
EMERGING GROWTH FUND (EMERGING GROWTH FUND); and TRAINER, WORTHAM TOTAL RETURN
BOND FUND (TOTAL RETURN BOND FUND). 
    

                       INVESTMENT OBJECTIVES AND POLICIES

INVESTMENT OBJECTIVES

FIRST MUTUAL FUND
The Fund seeks to achieve capital appreciation through investment in common
stocks and securities convertible into common stocks. Its secondary objective is
income.

   
EMERGING GROWTH FUND
    
The Fund seeks to achieve capital appreciation through investments in the common
stock of emerging growth companies which are defined as companies achieving or
about to achieve rapid earnings growth with weighted average market
capitalizations of approximately $1 billion. The Fund seeks to outperform equity
returns generated by relevant benchmark indices and funds with comparable
objectives by employing proprietary fundamental, technical and valuation
analysis in the selection of smaller-capitalization, publicly-traded U.S.
companies.

   
TOTAL RETURN BOND FUND
The Fund seeks to maximize total return, consistent with preservation of
capital.
    

INVESTMENT POLICIES
   
The following discussion of investment techniques and instruments should be read
in conjunction with the "INVESTMENT OBJECTIVE AND POLICIES" and "INVESTMENT
STRATEGIES AND RISK CONSIDERATIONS" sections of the Prospectus.

The Board of Trustees may, in the future, authorize a Fund to invest in
securities other than those listed herein and in the Prospectus, provided such
investment would be consistent with that Fund's investment objective and that it
would not violate any fundamental investment policies or restrictions applicable
to that Fund.
    

The following discussion applies to all of the Funds.

   
Each Fund will not, as to 75% of its total assets, purchase the securities of
any one issuer (other than cash, cash items, and obligations of the United
States Government) if immediately thereafter, and as a result of the purchase,
the Fund would (a) have more than 5% of the value of its total assets invested
in the securities of such issuer, or (b) hold more than 10% of any or all
classes of the securities of any one issuer. The Funds will not invest in the
securities of other investment companies. Although permitted under the Trust's
Declaration of Trust and By-laws, the following types of transactions are not
currently anticipated:
    

          1.   Investment in restricted securities (including non-marketable
               securities);

          2.   Engaging in short selling; and

          3.   Arbitrage activities.

Although it is not the current intention of the Funds to borrow, each Fund may
borrow for the purpose of investing in portfolio securities. To the extent that
the Funds borrow money, they will incur interest expense. Any investment gains
made with the additional funds in excess of interest paid will cause the net
asset value of the Fund's shares to rise faster than would, otherwise be the
case. Conversely, any investment losses from such monies will cause the net
asset value of the Funds shares to fall faster than would otherwise be the case.
The foregoing investment policies may be changed without shareholder approval
except to the extent they are reflected in a Fund's fundamental policies. (See
"INVESTMENT RESTRICTIONS" below.)
    

                             INVESTMENT RESTRICTIONS

The Funds have adopted the following restrictions with respect to their
investment policies. These restrictions are fundamental policies, and may not be
changed as to a Fund unless authorized by the vote of a majority of the
outstanding shares of the Fund, as that term is defined herein under the section
entitled "GENERAL INFORMATION" below.

          (a)    UNDERWRITING OF SECURITIES: The Funds will not engage in the
                 underwriting of securities of other issuers.

          (b)    DIVERSIFICATION: The Funds have adopted the policy prohibiting
                 it from, as to 75% of each Fund's total assets, investing more
                 than 5% of its total assets in the securities of any one issuer
                 (other than securities issued by the Government or its agencies
                 or instrumentalities).

          (c)    INDUSTRY CONCENTRATIONS: The Funds may not purchase the
                 securities of issuers conducting their principal business
                 activities in the same industry, other than obligations issued
                 or guaranteed by the U.S. Government, its agencies or
                 instrumentalities if immediately after such purchase the value
                 of a Fund's investments in such industry would exceed 25% of
                 the value of the total assets of the Fund.

          (d)    PURCHASE AND SALE OF REAL ESTATE: The Funds will not engage in
                 the purchase and sale of interests in real estate except that
                 the Funds may engage in the purchase and sale of marketable
                 securities which may represent indirect interests in real
                 estate.

          (e)    PURCHASE AND SALE OF COMMODITIES OR COMMODITY CONTRACTS: The
                 Funds will not engage in the purchase and sale of commodities
                 or commodity contracts.

          (f)    MAKING OF LOANS TO OTHER PERSONS: The Funds will not make loans
                 to any person or company, except that the Funds may purchase a
                 portion of an issue of publicly distributed bonds, debentures
                 or other debt securities and except further that the Funds may
                 enter into repurchase agreements.

   

          (g)    BORROWING  OF MONEY:  From time to time,  the Funds may  borrow
                 money. All such borrowings shall be exclusively from banks. The
                 purpose of such borrowings  shall be both for temporary use and
                 to provide  funds for the  purchase of  additional  investments
                 whenever  the  Board of  Trustees  of the Trust  shall  deem it
                 desirable.  In connection with any such borrowing, a Fund shall
                 issue  promissory  notes or other evidences of indebtedness and
                 shall, when required,  pledge, assign or otherwise encumber its
                 assets,  provided,  however,  (i) that  immediately  after such
                 borrowing it shall have an asset  coverage of at least 300% for
                 all its  borrowing  and  (ii)  that  in the  event  such  asset
                 coverage  shall at any time fall  below  300% it shall,  within
                 three days thereafter  (not including  Sundays and holidays) or
                 such  longer  periods  as  the  U.S.  Securities  and  Exchange
                 Commission (the "SEC") may prescribe by rules and  regulations,
                 reduce the amount of its borrowings to an extent that the asset
                 coverage of the borrowings shall be at least 300%.

          (i)    SECURITIES OF OTHER INVESTMENT COMPANIES: The Funds will not
                 invest in the securities of other investment companies.

          (j)    ISSUANCE OF SENIOR SECURITIES: The Funds are not authorized to
                 issue securities senior to the shares offered by this
                 Prospectus, except in connection with borrowings under the
                 terms described above under "BORROWING OF MONEY."

                          OTHER INVESTMENT RESTRICTIONS

         (a)    The Funds may not invest in oil, gas or mineral leases;

         (b)    The Funds may invest up to 5% of their total assets at the time
                of purchase in warrants. Included within this amount, but not to
                exceed 2% of the Fund's total assets are warrants which are not
                listed on the New York Stock Exchange or the American Stock
                Exchange. This restriction does not apply to warrants initially
                attached to securities purchased by the Funds;

         (c)    The Funds will not invest in real estate limited partnerships;
                and

         (d)    The Funds will not purchase securities on margin, but the Funds
                may obtain such short-term credits as may be necessary for the
                purchase and sale of securities.

   
         (e)    Purchase or retain the securities of any issuer if, to the
                knowledge of a Fund, any Officer or Trustee of the Fund or of
                its Investment Advisor owns beneficially more than 1/2 of 1% of
                the outstanding securities of such issuer, and such Officers and
                Trustees of the Fund or of its Investment Advisor who own more
                than 1/2 of 1%, own, in aggregate, more than 5% of the
                outstanding securities of such issuer.

               Investment Company Act of 1940, as amended (the "Act"). Mr. Como
               is an "interested person" by reason of his affiliation with the
               Advisor and as a result of being an Officer of the Trust. Mr.
               Elias may be regarded as an "interested person" by reason of a
               material business relationship with the Advisor. Ms. Thibadeau is
               an "interested person" because she is Mr. Como's sister.

consider such matters as the selection of the independent certified public
accountant for the Trust, review of the auditor's report on accounting
procedures and internal controls, review of the quarterly reports on brokerage
commissions paid by the Trust, and other issues referred to the Committee by the
full Board. The Audit Committee is currently comprised of four disinterested
Trustees; under the Trust's By-laws, the President also serves as an Ex-Officio

As of June 30, 1997, the compensation for disinterested Trustees included a fee
of $500 per meeting of the Board of Trustees attended and an annual retainer of
$3,000. In addition, the Trustees were reimbursed expenses incurred with
connection to their attendance at meetings of the Board of Trustees. Members of
the Audit Committee also receive fees for meetings attended. However, no Officer
of the Trust receives any compensation directly from the Trust for performing
the duties of their offices. The Advisor, of which Messrs. Como and Ghriskey are
officers and/or trustees, receives fees from the Trust for acting as its
Investment Advisor. (See the section entitled "INVESTMENT ADVISOR.")

                               INVESTMENT ADVISOR

   
In 1981, Trainer, Wortham & Co., Inc. ("the Advisor") became the Investment
Advisor of the Trust. The Advisor has offices at 845 Third Avenue, 6th Floor,
New York, N.Y. 10022. The Advisor, organized in 1981, continues an investment
counseling business which began in 1924 as Trainer & Associates. The Advisor is
registered as an investment advisor under the Investment Advisers Act of 1940,
as amended, and supervises approximately $2.3 billion in investment accounts.
The Advisor is owned entirely by the officers active in the day-to-day
management of portfolios. By reason of his stock ownership of 32% of the
Advisor, Charles V. Moore, President may be said to be a "controlling person" of
that firm.
    



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

<PAGE>   41



The Directors of the Advisor are: A. Alexander Arnold III, David P. Como, H.
Williamson Ghriskey, Jr., and Charles V. Moore. Mr. Como, Managing Director of
the Advisor, is the President and a Trustee of the Trust. Since 1982, Mr. Como
has been primarily responsible for the day-to-day investment management of the
Trust's portfolio. Mr. Ghriskey, Jr., Managing Director of the Advisor, is
Vice-President, and Treasurer of the Trust.

Each Fund's Investment Advisory Agreement provides that, subject to the general
supervision of the Trust's Board of Trustees and in accordance with the Fund's
investment objectives, policies, and restrictions, the Advisor will manage the
Fund's investment portfolio, make decisions with respect to and place orders for
all purchases and sales of the portfolio securities. Pursuant to the Investment
Advisory Agreements, the Advisor is not liable for any mistake of judgment,
mistake of law, or other loss to a Fund in connection with its performance under
the Investment Advisory Agreements except a loss resulting from a breach of
fiduciary duty with respect to the receipt of compensation for its services or a
loss resulting from willful misfeasance, bad faith or gross negligence on the
part of the Advisor in the performance of its duties, or by reason of its
reckless disregard of its obligations under the Investment Advisory Agreements.

   
Pursuant to individual Investment Advisory Agreements, with respect to FIRST
MUTUAL FUND, the Advisor receives an annual investment advisory fee, accrued
daily and paid monthly, of 0.75% of the Fund's average daily net assets; with
respect to EMERGING GROWTH FUND, the Advisor receives an annual fee, accrued
daily and paid monthly, of 1.25% of the Fund's average daily net assets, and
with respect to TOTAL RETURN BOND FUND, the Advisor receives an annual fee,
accrued daily and paid monthly , of 0.45% of the Fund's average daily net
assets. From time to time, the Advisor may waive receipt of its fees and/or
voluntarily assume certain Fund expenses, which would have the effect of
lowering a Fund's expense ratio and increasing yield to investors at the time
such amounts are waived or assumed, as the case may be. No Fund will reimburse
the Advisor at a later time for the expenses it has assumed.

For the fiscal years ended June 30, 1997, 1996 and 1995, with respect to FIRST
MUTUAL FUND, the Fund paid the Advisor fees aggregating $235,424, $191,340, and
$139,966, respectively.

With respect to EMERGING GROWTH FUND and TOTAL RETURN BOND FUND, from October 1,
1996 through June 30, 1997, the Advisor earned $12,848 and $22,431,
respectively, all of which it voluntarily waived.

FIRST MUTUAL FUND and EMERGING GROWTH FUND have each adopted a Plan of
Distribution (the "Plans") pursuant to Rule 12b-1 under the Act. Each Plan
permits the respective Fund to pay certain expenses associated with the
distribution of its shares. The Plan provides that FIRST MUTUAL FUND and
TRAINER, WORTHAM EMERGING GROWTH FUND will reimburse FPSB for actual
distribution and shareholder servicing expenses incurred by FPSB not exceeding,
on an annual basis, 0.25% of the respective Fund's average daily net assets.

In adopting the Plan, the Board of Trustees considered the likelihood that the
Plan is designed to benefit each Fund and its shareholders by strengthening the
system for distributing the Fund's shares and thereby increasing sales and
reducing redemptions. Potential benefits from increased sales and reduced
redemptions include: (i) additional funds being available for investment,
thereby giving the Fund's portfolio manager greater flexibility in pursuing the
Fund's investment objectives; (ii) reducing the likelihood that an unusually
large demand for redemption would require disadvantageous liquidations of
portfolio investments; and (iii) increasing net assets, thereby reducing on a
per share basis those expenses which do not rise proportionately with net
assets. The Board of Trustees concluded that there was a reasonable likelihood
that each Fund and its shareholders would benefit from the adoption of the Plan.

Each Plan will terminate in the event of assignment and may be renewed for
successive one year periods provided that each continuance is specifically
approved by: (1) the vote of a majority of the Fund's outstanding voting shares
or by the Board of Trustees; and (2) the vote of a majority of the Board of
Trustees who are not "interested persons" of the Fund and who have no direct or
indirect financial interest in the Plan.

Any change in a Plan that would materially increase the amount of distribution
expense borne by the Fund requires shareholder approval; any other material
change requires approval by the Board of Trustees, including a majority of the
disinterested trustees as described above. On October 21, 1997, by unanimous
vote of the Trustees, the Plan for EMERGING GROWTH FUND was amended by lowering 
the fee from 0.50% to 0.25%. While a Plan is in effect, the selection and
nomination of a Fund's disinterested Trustees is committed to the disinterested
Trustees.

Each Plan authorizes the Fund to pay service organizations, which may include
but are not limited to: (1) compensation to securities brokers and dealers for
selling shares; (2) compensation to securities brokers and dealers, accountants,
attorneys, investment advisors and pension actuaries for services rendered to
their clients relating to the distribution of shares of the Fund; (3)
compensation to such parties for marketing research and promotional services
specifically relating to the distribution of Fund shares; (4) the costs of
advertising in newspapers, magazines or other periodicals, or on radio or
television; (5) the costs of telephone (including "WATS" and "800" services),
mail (including postage and other delivery costs) or other direct solicitation
of prospective investors; (6) the costs of preparing and printing prospectuses
and other sales material for prospective investors, and the cost of distributing
these materials; (7) the fees of public relations consultants; and (8) any other
distribution expenses that the Board of Trustees may from time to time approve
before such expenses are incurred.

All such payments made pursuant to a Plan shall be made for the purpose of
selling shares issued by the Fund. Payments of compensation pursuant to (3)
above may be based in whole or in part on a percentage of the regular salary
expense for those employees of such parties engaged in marketing research and
promotional services specifically relating to the distribution of Fund shares
based on the amount of time devoted by such employees to such activities, and
any out-of-pocket expenses associated with the distribution of Fund shares.

Each Plan provides that FPSB will be reimbursed on a monthly basis for expenses
incurred in connection with the distribution of Fund shares. During the fiscal
year ended June 30, 1997, distribution expenses for FIRST MUTUAL FUND were
reimbursed as follows:

                  TRANSFER AGENT AND ACCOUNTING SERVICES AGENT

   
FPS serves as the Trust's Transfer Agent, Dividend Disbursing Agent and
Redemption Agent pursuant to a Transfer Agent Services Agreement and also serves
as the Trust's Accounting Services Agent pursuant to an Accounting Services
Agreement (the "Accounting and Transfer Agent Services Agreements"). The
Accounting and Transfer Agent Services Agreements will continue in effect from
year to year, provided such continuance is specifically approved at least
annually by the Board of Trustees or by a vote of a majority of the outstanding
shares of the Trust (as defined under the section entitled "GENERAL INFORMATION"
in the Prospectus), and a majority of the Board of Trustees who are not
interested persons (as defined in the Act) of any party to the respective
Agreements, by votes cast in person at a meeting called for such purpose.
    

The Accounting and Transfer Agent Services Agreements provide generally that FPS
shall be indemnified against liabilities to the Trust in connection with matters
relating to the Accounting and Transfer Agent Services Agreements except those
arising out of willful misfeasance, bad faith or gross negligence on the part of
FPS in the performance of its duties or from reckless disregard of its
obligations and duties thereunder.

The Trust pays FPS an annual fee of $15.00 per shareholder account (subject to a
minimum monthly fee of $ $2,250) for its services as Transfer Agent, Dividend
Disbursing Agent and Redemption Agent. For accounting services, FPS receives
from the Trust an annual fee, payable monthly, of $24,000 on the first $10
million of average daily net assets; .0004% on the next $40 million of average
daily net assets; .0003% of the next $50 million of average daily net assets;
and .0001% of average daily net assets in excess of $100 million.

UMB Bank, KC, NA, P.O. Box 412797, Kansas City, MO is Custodian for the
securities and cash of each Fund.

                                  LEGAL COUNSEL

 Dechert, Price & Rhoads, Washington, DC serves as Counsel to the Trust.

                                    AUDITORS

   
Briggs, Bunting and Dougherty, LLP, 2121 Two Logan Square, 18th & Arch Streets,
Philadelphia, PA 19103-4901 have been selected as the independent accountants
for the Funds and will provide audit and tax services. The books of the Funds
will be audited at least once each year by Briggs, Bunting and Dougherty, LLP.
    


                                    BROKERAGE

   
It is the policy of each Fund to secure the execution of orders on its portfolio
transactions in an effective manner at the most favorable price. Pursuant to its
agreement with each Fund, the Advisor determines, subject to the general
supervision of the Board of Trustees and in accordance with the Fund's
investment objectives, policies and restrictions, which securities are to be
purchased and sold and which brokers are to be eligible to execute its portfolio
transactions. It is not the policy of the Funds to deal solely with one broker,
but it is each Fund's intention to place portfolio transactions with those
brokers which provide the most favorable combination of price, execution and
services to the Trust. Research services are a factor in selection of brokers,
but payment in excess of brokerage commissions charged by other brokers is not
made in recognition of research services. The reasonableness of brokerage
commissions is evaluated by comparison to fees charged by other brokers where
the execution and services are comparable.

During the fiscal year ended June 30, 1997, FIRST MUTUAL FUND paid a total of
$99,150.57 in brokerage commissions; $73,171.25 for fiscal year 1996; and
$132,302.77 for fiscal year 1995. EMERGING GROWTH FUND paid a total of $5,145 in
brokerage commissions for the fiscal period ended June 30, 1997. The Board of
Trustees, including a majority of the disinterested Trustees, have adopted
certain procedures pursuant to Rule 17e-1 governing brokerage transactions
between the Trust and affiliated brokers. The Trust has, in the past, paid
brokerage commissions to brokers which are affiliated with Officers and Trustees
of the Trust. During the fiscal years ended June 30, 1997, 1996 and 1995 the
Trust paid no such brokerage commissions.
    


                         INDIVIDUAL RETIREMENT ACCOUNTS

   
Each Fund will offer certain IRAs for use by any individual with compensation
for services rendered (including earned income from self-employment) who wishes
to use shares of the Fund as a funding medium for individual retirement saving.
The only exception is an individual who has attained, or will attain, age 70 1/2
before the end of the taxable year. Such an individual may only contribute to an
IRA for his or her nonworking spouse under age 70 1/2.

<PAGE>   45



   
Many changes to existing IRA tax laws will become effective in 1997, including
the execution of two new types of IRAs, as discussed in the Prospectus.
    



   
    

   
In an IRA, distributions of net investment income and capital gains will be
automatically reinvested in the Fund. Retirement plan participants will be
billed for all maintenance fees which are to be paid to UMB Bank, MO. Payment
may be made through liquidation of shares of the Fund.
    

UMB Bank furnishes custodial services for the IRA for a service fee chargeable
as follows: (a) annual maintenance fee - $10 (per participant's account); (b)
lump sum distribution or termination fee - $7 (per participant's account); and
(c) periodic cash distributions - $1 (each payment).

   
The foregoing brief description is not a complete or definitive explanation of
the IRAs available for investment in the Fund. Any person who wishes to
establish a retirement plan account may do so by contacting the Fund. The
complete IRA documents and applications will be provided to existing or
prospective shareholders upon request, without obligation. Since this IRA
involves a commitment covering future years, it is important that the investor
consider his or her needs and whether the investment objective of the Trust as
described in the Prospectus and this Statement of Additional Information is most
likely to fulfill them. The Funds recommends that investors consult their
attorneys or tax advisors if they are uncertain that the retirement programs
described herein are appropriate for their needs.
    

                            PERFORMANCE CALCULATIONS

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

- --------------------------------------------------------------------------------
Trainer, Wortham First Mutual Funds - PEA #58                            Page 14

<PAGE>   46



                 ERV = P(1 + T)to the power of n

Where:              ERV    =   ending redeemable value at the end of the period 
                               covered by the computation of a hypothetical 
                               $1,000 payment made at the beginning of the 
                               period.

                    P      =   hypothetical initial payment of $1,000.

                    n      =   period covered by the computation, expressed in 
                               terms of years.

                    T      =   average annual total return.

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

                               Aggregate Total Return =  [ (ERV) - 1 ]
                                                           -----
                                                             P


Where:              ERV    =   ending redeemable value at the end of the period
                               covered by the computation of a hypothetical 
                               $1,000 payment made at the beginning of the 
                               period.

                    P      =   hypothetical initial payment of $1,000.

The calculations of average annual total return and aggregate total return
assume the reinvestment of all dividends and capital gain distributions on the
reinvestment dates during the period. The ending redeemable value (variable
"ERV" in each formula) is determined by assuming complete redemption of the
hypothetical investment and the deduction of all nonrecurring charges at the end
of the period covered by the computations.

   
Based on the foregoing calculations, the average annual total returns for the
FIRST MUTUAL FUND for the one year, five year and ten year periods ended June
30, 1997 were 7.67%, 16.69% and 10.37%, respectively. The aggregate total
returns for the same five and ten year periods were 116.37% and 168.22%,
respectively. The total returns for EMERGING GROWTH FUND and TOTAL RETURN BOND
FUND for the period from October 1, 1996 through June 30, 1997 are 2.10% and
4.90%, respectively.
    

The Trainer, Wortham Total Return Bond Fund may also quote its yield in
advertisements and investor communications. The yield computation is determined
by dividing the net investment income per share earned during a recent 30-day
(or one month) period by the maximum offering price per share on the last day of
that period and annualizing the resulting figure, according to the following
formula:

                            YIELD = 2 [ ( a - b + 1) to the sixth power - 1 ]
                                          ------ 
                                            cd

Where:              a = dividends and interest earned during the period;
                    b = expenses accrued for the period (net of reimbursements);
                    c = the average daily number of shares outstanding during
                        the period that were entitled to receive dividends; and
                    d = the maximum offering price per share on the last day of
                        the period.

For the thirty day period ended June 30, 1997, TOTAL RETURN BOND FUND had a
yield of 5.77%. Since performance will fluctuate, performance data for the Funds
should not be used to compare an investment in the Fund's shares with bank
deposits, savings accounts and similar investment alternatives which often
provide an agreed-upon or guaranteed fixed yield for a stated period of time.
Shareholders should remember that performance is generally a function of the
kind and quality of the instruments held in a portfolio, portfolio maturity,
operating expenses and market conditions.
    

                               GENERAL INFORMATION

Item 27. Indemnification
         ---------------

                      Article VII, Section 2 of the Registrant's Agreement and
                      Declaration of Trust provides as follows: The Trustees
                      shall not be responsible or liable in any event for any
                      neglect or wrongdoing of any officer, agent, employee,
                      Manager or Principal Underwriter of the Trust, nor shall
                      any Trustee be responsible for the act or omission of any
                      other Trustee, and, subject to the provisions of the
                      Bylaws, the Trust out of its assets may indemnify and hold
                      harmless each and every trustee and officer of the Trust
                      from an against any and all claims, demands, costs,
                      losses, expenses, and damages whatsoever arising out of or
                      related to such Trustee's performance of his or her duties
                      as a Trustee or officer of the Trust; provided that
                      nothing herein contained shall indemnify, hold harmless or
                      protect any Trustee or officer from or against any
                      liability to the Trust or any Shareholder to which he or
                      she would otherwise be subject by reason of wilful
                      misfeasance, bad faith, gross negligence or reckless
                      disregard of the duties involved in the conduct of his or
                      her office.

                      Every note, bond, contract, instrument, certificate or
                      undertaking and every other act or thing whatsoever
                      issued, executed or done by or on behalf of the Trust or
                      the Trustees or any of them in connection with the Trust
                      shall be conclusively deemed to have been issued, executed
                      or done only in or with respect to their or his or her
                      capacity as Trustees or Trustee, and such Trustees or
                      Trustee shall not be personally liable thereon.

                      Article Sixth of the By-Laws of the Trust provide that any
                      trustee and officer shall be indemnified against
                      reasonable costs and expenses incurred in connection with
                      any proceeding to which he or she is made a party by
                      reason of his being or having been a trustee or officer of
                      the Trust, except in relation to any action, suit or
                      proceeding in which he or she is adjudged liable because
                      of willful misfeasance, bad faith, gross negligence or
                      reckless disregard of the duties involved in the conduct
                      of his office. In the absence of an adjudication which
                      expressly absolves a trustee or officer of liability for
                      such willful misfeasance, etc., a written opinion of
                      independent counsel is required prior to payment of
                      indemnification.

                      Indemnification of the Trust's investment advisor,
                      distributor, custodian, administrator, transfer agent,
                      dividend disbursing and redemption agent and accounting
                      services agent is provided for, respectively, in Section 8
                      of the Investment Advisory Agreement (Exhibit 5(a));
                      Section 8 of the Underwriting Agreement (Exhibit 6(a)),
                      Section 18 of the Custodian Agreement (Exhibit 8), Section
                      25 of the Administration Agreement (Exhibit 9(a)) Section
                      8(d) of the Administration Agreement (Exhibit 9(c)), and
                      Section 23 of the Accounting Services Agreement (Exhibit
                      9(c)).

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