                                                      MESSAGE FROM THE PRESIDENT

We are pleased to send you Summit Mutual Funds' 2004 Semiannual Report for the
period ended March 31, 2004. We welcome new investors and thank existing
shareholders as we strive to help you reach your financial goals.

The fiscal year began with encouraging economic news about strong GDP growth
rates. Continued concerns about the rate of jobs growth allowed the Federal
Reserve to maintain historically low interest rates and perpetuate a favorable
environment for both fixed income and equity investors. By the end of the
reporting period in March, positive GDP rates continued and are now accompanied
by robust jobs growth and positive corporate earnings reports. These conditions
have caused the Federal Reserve to begin talking about the need to raise
interest rates.

This recent economic news has been accompanied by mixed signals on the
geopolitical front. A year after the start of the war in Iraq, coalition forces
had Saddam Hussein in custody and Iraqi leaders took steps toward forming a
democratic government; but violence has recently escalated. The commuter train
bombings in Madrid, Spain also exacerbated fears of renewed global terrorism.
All of this is occurring in a backdrop of a presidential election year. The
result creates uncertainty for many investors.

Equity markets responded by continuing the rally that began just over a year
ago. The S&P 500 Index advanced 14.1%, the S&P 400 MidCap Index returned 18.9%
and the Russell 2000 Index soared by 21.7% during the six month period ended
March 31, 2004. In other market sectors, the Nasdaq-100 Index increased 10.5%
while, in international arenas, the EAFE Index advanced 22.2%, helped by a weak
U.S. dollar. It should be noted, that most of these positive equity returns
occurred during the fourth quarter of 2003, prior to reports of accelerated jobs
growth, interest rate increases, and greater international unrest.

Fixed income markets ended the six months close to where they began, but
experienced a reasonable level of volatility throughout the period. Rates on the
10 year U.S. Treasury Note opened the fiscal year yielding 3.9% and ended the
six month period nearly unchanged at 3.8%. During the period, this rate moved as
high as 4.5% and as low as 3.7%. This generally low interest yield environment
and the point-to-point rate stability contributed to the modest 3.0% return for
the Lehman Aggregate Bond Index during the six months ended March 31, 2004.

"PROPER DIVERSIFICATION OF YOUR INVESTMENTS IS A CRITICAL COMPONENT OF ACHIEVING
YOUR LONG-TERM INVESTMENT GOALS"

These events reinforce our message that the basic principles for investing
remain unchanged, even when equity and fixed income returns are positive. Our
thoughts have always been to maintain the proper perspective, have realistic
expectations and ensure that your investment strategy is appropriate for your
risk tolerance and time horizon. Concepts such as asset allocation and portfolio
rebalancing remain as important as ever. Proper diversification of your
investments, both within and across asset sectors, (or specifically stocks,
bonds and cash) is a critical component of achieving your long-term investment
goals. With three equity, three fixed income and a money market fund, Summit
Mutual Funds is able to provide the foundation of a diversified investment plan.

RECENT HIGHLIGHTS:

- -    Summit's Everest Fund continued its excellent performance (up 15.3%)
     ranking it as a top performer by leading rating agencies.

- -    The Bond Fund's recent performance ranked it highly by leading ratings
     agencies.

Thank you for choosing Summit Funds during these challenging times for investors
and for the trust that you have placed in us.

Best regards,

/s/ Steven R. Sutermeister

SUMMIT MUTUAL FUNDS, INC. - APEX SERIES
NASDAQ-100 INDEX FUND

OBJECTIVE - Seeks investment results that correspond to the investment
performance of U.S. common stocks, as represented by the Nasdaq-100 Index (the
"Index").

STRATEGY - The Nasdaq-100 Index Fund (the "Fund") will remain fully invested in
stocks included in the Index and in futures contracts on the Index. The cash
position will be held in highly liquid money market instruments to meet
redemptions and to provide cash for future stock purchases.

MANAGER'S COMMENTS:

For the six-month period ended March 31, 2004, the Fund's (Class I) total return
was 9.91% (before the impact of any product or contract-level fees). This
compares to a 10.48% total return for the Index. The difference of 0.57% is
referred to as "tracking error" and is largely attributed to the Fund's
operating expense ratio. These expenses represent the Fund's costs for advisory,
administration, accounting, custody and other services that are detailed in the
Statement of Operations. The remaining difference can be caused by a number of
factors, including the timing and size of cash flows into and out of the Fund;
broker's commissions or other trading costs; and holding security positions in
amounts that are different than the weightings in the Index, among others. While
an exact replication of the capitalization weightings of securities in the Index
is not feasible, the Fund's objectives and strategies call for a correlation of
at least 95% between the Fund's pre-expense total return and that of the Index.
The Fund achieved this level of correlation for the period presented.

SUMMIT MUTUAL FUNDS, INC. - APEX SERIES
TOTAL SOCIAL IMPACT FUND

OBJECTIVE - Seeks investment results that closely correspond to the total return
performance of U.S. common stocks, as represented by the Standard and Poor's 500
Composite Stock Index (the "Index"). The Total Social Impact Fund seeks to
promote better business practices by investing more in companies in the Index
that conduct their business commendably with respect to their stakeholders.

STRATEGY - The Total Social Impact Fund (the "Fund") will invest in all stocks
that are included in the Index. However, the percentage invested in each stock
will vary from the Index weighting to reflect the company's Total Social Impact
(TSI) rating. The TSI rating reflects the company's scoring on a series of
benchmarks corresponding to each of its stakeholders.

MANAGER'S COMMENTS:

The Fund is now three years old, celebrating the occasion at the end of 2003.
This three year old has experienced a wild infancy so far: market collapse,
corporate scandals, mutual fund scandals and regulatory actions at levels not
seen in over sixty years. Despite all of this anxiety, the U.S. markets posted
excellent returns recently. Are we heading back to the "what have you done for
me lately" mentality or have we meaningfully improved corporate governance and
transparency? The jury is still out.

On a total return basis, the Fund (Class I) was up 13.22% versus 14.07% for the
Index. The underperformance is in large part attributable to the Fund's
operating expense ratio and to a less than benchmark weighting in the financial
sector, 19.3% versus 21.3%. The mutual fund scandals of 2003 resulted in
significant TSI score downgrades in the fourth quarter. Reductions in ratings of
nearly 25% were applied to Bank of America, Banc One, Citigroup, Federated,
Janus, Marsh-Putnam, Merrill Lynch, Morgan Stanley and Prudential Financial.
Despite these scandals, many of these stocks turned in superior performance in
the last six months. As the Fund had reduced holdings due to the lowered scores,
performance versus the benchmark suffered.

The Fund continues in 2004 to vote for separation of the CEO and Chairman of the
Board roles. Despite the outcry for enhanced corporate governance, fewer than
10% of the companies in the Index have separation of these roles. In a critical
shareholder vote at Disney, 43% of shareholders withheld votes for Michael
Eisner resulting in him stepping down as chairman. He retains his CEO title. The
stage has been set for significant corporate governance showdowns this year. In
addition to supporting this position, TSI also supports the expensing of stock
options, limitations on excessive compensation through incentive compensation
plan awards and limitations on excessive severance payments without a
shareholder vote. The proxy voting season is well underway and TSI will vote on
every issue for every company in the Index. Should you desire to view our voting

                                         SUMMIT MUTUAL FUNDS, INC. - APEX SERIES
                                                                    EVEREST FUND

OBJECTIVE - Seeks primarily long-term appreciation of capital, without incurring
unduly high risk, by investing primarily in common stocks and other equity
securities. Current income is a secondary objective.

STRATEGY - The Everest Fund (the "Fund") will remain in a highly invested
position ranging from 86% to 98%. The cash position will be held in highly
liquid money market instruments to meet redemptions and to provide cash for
future stock purchases as new opportunities arise.

MANAGER'S COMMENTS:

The Fund's (Class I) performance for the period October 1, 2003 to March 31,
2004 was 15.25% versus 17.64% for the Russell 1000 Value Index (the "Index") and
14.07% for the S & P 500 Index.

After three negative return years in the equity indices, 2003 rebounded smartly
with investors returning with plenty of firepower. The economy started to
recover in earnest during the second half of 2003 after three years of
lackluster performance. The Federal Reserve's "easy money" policy of low
interest rates started to kick-start the economy and resuscitate corporations'
and consumers' balance sheets. With low interest rates and economic recovery,
equities looked inexpensive again.

The performance of the Fund benefited from the acquisition of Fleetbank by
BankAmerica, recovery in Motorola and Nokia, consumer staple rebound by Conagra
and Altria, and a surge in energy holdings and energy service firms. The Fund's
underperformance compared to the Index primarily was a result of underweighting
the financial sector (24% to 36% at March 31, 2004) that outperformed the
overall Index. Additionally, the Fund over-weighted the healthcare sector (11%
to 3%) that underperformed the overall Index.

With the economic recovery, the fixed income markets' dominance over equity
markets may be ending. The perfect scenario, ever-lower fed funds rates, no
signs of inflation or economic recovery are now being replaced by incipient
inflation and economic growth. The missing ingredient - a rising fed funds
rate-is now held in check only by political expedience. Does Greenspan want to
be the whipping boy for either political party by choking off economic growth
without a robust jobs market?

The Fund believed that a fourth down year was unacceptable politically and
invested with the belief that the market would rebound, while purchasing
companies with sufficient economic heft to survive if our timing was premature.
Fortunately a declining stock market makes most value securities more attractive
as prices decline. After this years' market rebound investors' enthusiasm has

SUMMIT MUTUAL FUNDS, INC. - APEX SERIES
BOND FUND

OBJECTIVE - Seeks a high level of current income, without undue risk to
principal, by investing in long-term, fixed-income, investment-grade corporate
bonds.

STRATEGY - The Bond Fund (the "Fund") intends to invest at least 75% of the
value of its assets in publicly-traded straight debt securities which have a
rating within the four highest grades as rated by a national rating agency. Up
to 25% of the portfolio may be invested in below investment grade debt
securities or convertible debt securities. Up to 20% of the portfolio may be
invested in convertible preferred and preferred stock or other securities.

MANAGER'S COMMENTS:

The Fund had a total return of 4.59% (before contract fees and expenses) for the
six month period ended March 31, 2004 compared to a total return of 2.98% for
the Lehman Brothers Aggregate Index (the "Index"). The past six months were
marked by continued volatility in the fixed income market. While interest rates
ended relatively unchanged from six months earlier, both short and long-term
interest rates moved over a range of 65 to 80 basis points during the period.
Robust GDP growth was offset by slow job growth and continued low inflation,
allowing the Federal Reserve to maintain an accommodative monetary policy.

The Fund's out performance to the Index was primarily the result of the
continued overweight in the corporate bond sector. Corporate bonds, both
investment grade and high yield, were the best performing sector of the fixed
income market during the period. In general, lower rated credits, lead by high
yield bonds, provided the largest contribution to the incremental return.
Mortgage-backed securities outperformed similar duration U.S. Treasury
Securities but generally lagged corporate bonds. Individual sectors that
provided the largest positive performance during the period were commercial
mortgage-backed securities, financial institutions, manufactured housing,
telecom and utilities. Over the last six months, the U.S. Treasury sector, while
providing positive returns, underperformed all other sectors of the fixed income
market.

                                                      SHORT-TERM GOVERNMENT FUND

OBJECTIVE - Seeks to provide a high level of current income and preservation of
capital by investing 100% of total net assets in bonds issued by the U.S.
government or its agencies or instrumentalities.

STRATEGY - The Short-term Government Fund (the "Fund") intends to invest 100% of
the value of its assets in bonds issued by the U.S. government and its agencies.

MANAGER'S COMMENTS:

The Fund had a total return of 1.00% (before contract fees and expenses) for the
six month period ended March 31, 2004 compared to a total return of 1.53% for
the Salomon 1-5 Year Treasury Index (the "Index"). Over the last six months, the
fixed income sector was marked by continued volatility. The range for the 2-year
Treasury was 65 basis points while the range for longer maturities was
approximately 80 basis points. The Treasury yield curve flattened with the
2-year Treasury rising 11 basis points and the 10-year Treasury declining 10
basis points during the period. Inflation remained low which along with slow job
growth allowed the Federal Reserve to maintain its target interest rate of 1% in
the face of robust GDP growth.

The Fund's underperformance to the Index was primarily a result of a shorter
duration and asset allocation. During the period, interest rates rose on the
short end of the curve while decreasing on the longer end resulting in longer
maturities outperforming. The Fund was over-weighted in the shorter maturity
sector versus the longer sector resulting in underperformance during the period.
The U.S. Treasury notes with a maturity longer than 3 years and the mortgage
pass-through securities provided the largest incremental returns. The U.S.
Agency sector generally outperformed similar maturity U.S. Treasury Securities.
The sectors that provided the largest negative contribution to the Fund included
very short maturity agency and U.S. Treasury Notes along with the short maturity
collateralized mortgage obligations (CMOs).

SUMMIT MUTUAL FUNDS, INC. - APEX SERIES
HIGH YIELD BOND FUND

OBJECTIVE - Seeks high current income and capital appreciation, secondarily.

STRATEGY - The High Yield Bond Fund (the "Fund") intends to invest primarily in
high yield, high risk bonds, with intermediate maturities.

MANAGER'S COMMENTS:

The high yield market continued its impressive performance over the last six
months, with interest rates moderately lower, spreads moderately tighter and the
economy showing continued signs of improvement. Not surprisingly, these factors
have lead to increased cash flows into high yield mutual funds by the investing
public. After the tremendous tightening in high yield bond spreads over the last
18 months, we have now reached levels that are closer to the historical
averages.

The Fund had a total return of 8.75% for the six months ended March 31, 2004,
including the reinvestment of dividends. This compares favorably to a return of
8.25% for the Merrill Lynch High Yield Master II Index (the "Index") during the
same period. The Fund's outperformance to the Index was primarily due to its
investments in lower quality and distressed investments during the period. Some
of the sectors included airlines, power generators and lodging.

Looking forward, on the positive side, corporate profitability appears to be
improving, generally. While each sector of the economy, and each individual
company, has its own profit dynamics, the overall picture on profitability is
improving. Lower interest rates have allowed many companies to refinance debt at
substantial savings, which has helped improve credit statistics. In addition,
default rates continue to decline from their very high levels of 2001 and 2002.
On the negative side, the general level of interest rates may rise in the
future, as the economy strengthens, which would provide a head-wind for the high
yield bond market. In addition, the large cash flows into high yield mutual
funds have slowed significantly during 2004, at least for the time being. These
countervailing forces will play themselves out during the balance of the year
and determine the ultimate return for the high yield market in 2004.

SUMMIT MUTUAL FUNDS, INC. - APEX SERIES
MONEY MARKET FUND

OBJECTIVE - Seeks to maintain stability of capital and to maintain the liquidity
of capital and to provide current income.

STRATEGY - The Money Market Fund intends to invest 100% of the value of its
assets in high quality short-term securities.

MANAGER'S COMMENTS:

The U.S. economy continued its momentum for the most recent semiannual period.
The positive flow of data, including strong durable goods orders, a healthy
housing market, lower weekly jobless claims, as well as an improving
manufacturing sector all suggest that the current recovery is sustainable. The
improving economy was reflected in the 4% growth in GDP over the 4th quarter.

With the economy showing marked improvement and corporate profits up, the focus
turned to job growth for assurance that the recovery was sustainable.
Unfortunately investors were disappointed in the new year. Job growth in the
first quarter was negligible as payrolls averaged less than 50,000 jobs per
month despite the expectation of a steady 4% GDP growth for the 1st quarter. The
dollar continued to weaken against the Euro touching a record low in February
and consumer sentiment, which in January hit at a three-year high, suffered
substantially over the subsequent months.

The Federal Reserve shifted their risk assessment to balanced in December as the
fear of disinflation faded. It also acknowledged the lack of jobs growth but
made statements expressing optimism. The Federal Reserve's language also shifted
regarding interest rates, suggesting that while the current target of 1% may be
accommodative, rates will eventually rise.

Early in the 3rd quarter we continued to extend the portfolio. As the
progressively disappointing labor data were reported throughout the first
quarter, the yield curve flattened. Once this occurred, we began to change our
strategy in anticipation of higher rates and a steeper yield curve. Most of our
purchases were focused in the shorter end of the curve as we felt that longer
purchases were too expensive. We have also added more floating rate securities
to the portfolio. Should the labor market turn around, floaters will provide
protection in an increasing rate environment. We are anticipating an improvement
in the labor market in the months to come and expect the yield curve to steepen
accordingly.

                                         SUMMIT MUTUAL FUNDS, INC. - APEX SERIES
                                                   NOTES TO FINANCIAL STATEMENTS

MARCH 31, 2004 (UNAUDITED)

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Summit Mutual Funds, Inc. ("Summit Mutual Funds") is registered under the
Investment Company Act of 1940, as amended, as a no-load, diversified, open-end
management investment company. Summit Mutual Funds is offered in two series, the
Pinnacle Series and the Apex Series. The shares of the Apex Series (the
"Series") are offered without sales charge to institutional and retail
investors. These funds are also offered to insurance company exempt separate
accounts, including The Union Central Life Insurance Company (parent company of
Summit Investment Partners Inc., the Adviser). The Series' shares are offered in
seven different funds - Nasdaq-100 Index Fund, Total Social Impact Fund, Everest
Fund, Bond Fund, Short-term Government Fund, High Yield Bond Fund, and Money
Market Fund (individually "Fund", collectively "Funds"). The Nasdaq-100 Index
Fund seeks investment results that correspond to the total return performance of
common stocks as represented by its respective index. The Total Social Impact
Fund seeks investment results that closely correspond to the total return
performance of U.S. common stocks, as presented by the S&P 500 Index. The Total
Social Impact Fund also seeks to promote better business practices by investing
more in companies in the S&P 500 Index that conduct their business commendably
with respect to their stakeholders. The Everest Fund seeks long-term
appreciation of capital, without incurring unduly high risk, by investing
primarily in common stocks and other equity securities. Current income is a
secondary objective. The Bond Fund seeks as high a level of current income as is
consistent with reasonable investment risk, by investing primarily in long-term,
fixed-income, investment-grade corporate bonds. The Short-term Government Fund
seeks to provide a high level of current income and preservation of capital by
investing 100% of its total assets in bonds issued by the U.S. government and
its agencies. The High Yield Bond Fund seeks high current income and capital
appreciation, secondarily, by investing primarily in high yield, high risk
bonds, with intermediate maturities. The Money Market Fund seeks to maintain
stability of capital and, consistent therewith, to maintain the liquidity of
capital and to provide current income. The results of the Fund(s) for your
investment product are included herein.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America ("generally accepted
accounting principles") requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

SECURITIES VALUATION - Securities held in each Fund, except for money market
instruments maturing in 60 days or less, are valued as follows: Securities
traded on stock exchanges (including securities traded in both the
over-the-counter market and on an exchange), or listed on the NASDAQ National
Market System, are valued at the last sales price as of the close of the
New York Stock Exchange on the day the securities are being valued, or, lacking
any sales, at the closing bid prices. Alternatively, NASDAQ listed securities
may be valued on the basis of the NASDAQ Official Closing Price. Securities
traded only in the over-the-counter market are valued at the last bid price, as
of the close of trading on the New York Stock Exchange, quoted by brokers that
make markets in the securities. Other securities for which market quotations are
not readily available are valued at fair value as determined in good faith under
procedures adopted by the Board of Directors. Money market instruments maturing
in 60 days or less are valued at amortized cost, which approximates market.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME - Securities transactions are
recorded on the trade date (the date the order to buy or sell is executed).
Dividend income is recorded on the ex-dividend date and interest income is
recorded on the accrual basis. All amortization of discount and premium is
recognized currently under the effective interest method. Gains and losses on
sales of investments are calculated on the identified cost basis for financial
reporting and tax purposes. Paydown gains and losses on mortgage and
asset-backed securities are presented as interest income.

FEDERAL TAXES - Each Fund contemplates declaring as dividends each year all, or
substantially all, of its taxable income, including net capital gains (the
excess of long-term capital gains over short-term capital losses). Shareholders
will be subject to income taxes on these distributions regardless of whether
they are paid in cash or reinvested in additional Fund shares. Distributions
attributable to the net capital gains of a Fund will be taxable to the
shareholder as long-term capital gains, regardless of how long the shareholder
has held the Fund shares. Other Fund distributions will generally be taxable as
ordinary income. The one major exception to these tax principles is that
distributions on, and sales, exchanges and redemptions of, Fund shares held in
an IRA (or other tax-qualified plan) will not be currently taxable. The
following percentages of fund dividends are

                                       45
<Page>

eligible for the reduced rate attributed to qualified dividend income under the
Jobs and Growth Tax Relief & Reconciliation Act of 2003: Total Social Impact
(100%).

Shareholders may also be subject to state and local taxes on distributions and
redemptions. State income taxes may not apply, however, to the portions of each
Funds' distributions, if any, that are attributable to interest on Federal
securities or interest on securities of the particular state. Shareholders
should consult their tax advisers regarding the tax status of distributions in
their state and locality.

It is the intent of Summit Mutual Funds to comply with the requirements under
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its net investment income and any net
realized capital gains. Accordingly, no provision for federal or state income
taxes has been recorded.

DISTRIBUTIONS - Distributions from net investment income in all fixed income
Funds, except Money Market Fund, are generally declared and paid quarterly.
Distributions from net investment income of the Money Market Fund are declared
daily and paid monthly. Equity Funds generally declare and pay dividends
annually. Net realized capital gains are distributed periodically, no less
frequently than annually. Distributions are recorded on the ex-dividend date.
All distributions are reinvested in additional shares of the respective Fund at
the net asset value per share unless you notify Summit Mutual Funds that you
elect to receive distributions in cash.

The amounts of distributions are determined in accordance with federal income
tax regulations, which may differ from generally accepted accounting principles
in the United States of America. These "book/tax" differences are either
considered temporary or permanent in nature. To the extent these differences are
permanent in nature, such amounts are reclassified within the capital accounts
based on their federal tax-basis treatment; temporary differences do not require
reclassification. Distributions which exceed net investment income and net
realized capital gains for financial reporting purposes but not for tax purposes
are reported as distributions in excess of net investment income or
distributions in excess of net realized capital gains. To the extent they exceed
net investment income and net realized capital gains for tax purposes, they are
reported as distributions of paid-in-capital.

EXPENSES - Allocable expenses of Summit Mutual Funds are charged to each Fund
based on the ratio of the net assets of each Fund to the combined net assets of
Summit Mutual Funds. Nonallocable expenses are charged to each Fund based on
specific identification.

FOREIGN CURRENCY - Summit Mutual Funds' accounting records are maintained in
U.S. dollars. Funds may purchase foreign securities within certain limitations
set forth in the Prospectus. Amounts denominated in or expected to settle in
foreign currencies are translated into U.S. dollars at the spot rate at the
close of the London Market. Summit Mutual Funds does not isolate that portion of
the results of operations resulting from changes in foreign exchange rates on
investments from the underlying fluctuation in the securities resulting from
market prices. All are included in net realized and unrealized gain or loss for
investments.

Foreign security and currency transactions may involve certain risks not
typically associated with those of U.S. companies including the level of
governmental supervision and regulations of foreign securities markets and the
possibility of political and economic instability.

FUTURES CONTRACTS AND FUND SECURITIES LOANED - Certain Funds may enter into
futures contracts for hedging purposes, including protecting the price or
interest rate of securities that the Fund intends to buy, that relate to
securities in which it may directly invest and indices comprised of such
securities may purchase and write call and put options on such contracts. Each
eligible Fund may invest up to 20% of its assets in such futures and/or options.
The Nasdaq-100 Index, Total Social Impact, and Everest Fund may invest up to
100% of their assets in such futures and/or options until each Fund reaches $50
million in net assets. These contracts provide for the sale of a specified
quantity of a financial instrument at a fixed price at a future date. When the
Funds enter into a futures contract, they are required to deposit, or designate
and maintain as collateral such initial margin as required by the exchange on
which the contract is traded. Under terms of the contract, the Funds agree to
receive from or pay to the broker an amount equal to the daily fluctuation in
the value of the contract (known as the variation margin). The variation margin
is recorded as unrealized gain or loss until the contract expires or is
otherwise closed, at which time the gain or loss is realized. The Funds invest

Index that they intend to

match. The potential risk to the Funds is that the change in the value in the
underlying securities may not correlate to the value of the contracts.

The Funds (except the Total Social Impact and Money Market Funds) lend their
securities to approved brokers to earn additional income and receive cash and/or
securities as collateral to secure the loans. Income from securities lending is
included in "Other Income" on the Statement of Operations. Collateral is
maintained at not less than 100% of the value of loaned securities. Although the
risk of lending is mitigated by the collateral, the Funds could experience a
delay in recovering its securities and a possible loss of income or value if the
borrower fails to return them. In addition to cash collateral, the Funds may
accept noncash collateral consisting of government securities and irrevocable
letters of credit from domestically domiciled banks.

NOTE 2 - TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISORY FEES - Summit Mutual Funds pays investment advisory fees to
Summit Investment Partners, Inc. (the "Adviser"), under terms of an Investment
Advisory Agreement (the "Agreement"). Certain officers and directors of the
Adviser are affiliated with Summit Mutual Funds. Summit Mutual Funds pays the
Adviser, as full compensation for all services and facilities furnished, a
monthly fee computed separately for each Fund on a daily basis.

ADMINISTRATION FEES - Summit Mutual Funds pays the Adviser to perform certain
administration services. The Fund shall pay the Adviser as full compensation for
all facilities and services furnished a fee computed separately for each
portfolio of the Fund.

DIRECTORS' FEES - Each director who is not affiliated with the Adviser receives
fees from Summit Mutual Funds for service as a director. Members of the Board of
Directors who are not affiliated with the Adviser are eligible to participate in
a deferred compensation plan. The value of each director's deferred compensation
account will increase or decrease at the same rate as if it were invested in
shares of the Summit Money Market Fund.

Summit Investment Partners, Inc. is a wholly-owned subsidiary of Union Central.

NOTE 3 - MULTIPLE CLASSES OF SHARES

The Nasdaq-100 Index, Total Social Impact, and Everest Funds began offering a
second class of shares (Class F). The Class F shares are subject to a
Distribution and Shareholder Service Plan ("12b-1 Plan"), which was approved by
the Funds' Board of Directors on March 1, 2002. The 12b-1 Plan provides that
each Distribution Plan Class shall pay to the Funds' Distributor, Carillon
Investments, Inc., a fee for payments the Distributor makes to banks, financial
planners, retirement plan service providers, broker/dealers and other
institutions for distribution assistance and/or shareholder services in
connection with the Distribution Plan Class shares. The fee shall be in an
amount not to exceed on an annual basis 0.25% of the average daily net asset
value of each Distribution Plan Class. Since the fee is paid out of the assets
or income of the Distribution Plan Class on an ongoing basis, over time the fee
will increase the cost and reduce the return of an investment.

The two classes of shares represent interests in the same portfolio of
investments, have the same rights, and are generally identical in all respects
except that each class bears its separate class-specific expenses, and has
exclusive voting rights with respect to any matter on which a separate vote of
any class is required. Income, non-class specific expenses and
realized/unrealized gains and losses are allocated to the respective classes on
the basis of the relative daily net assets.
