COMMENTARY(1)

                                                                   June 30, 2004

OVERVIEW

The Fund generated a loss of 0.98% for the second quarter, compared to a 0.47%
gain for the Russell 2000 Index and a 0.85% gain for the Russell 2000 Value
Index. The modest gains posted by small cap stocks in the second quarter were
the lowest since the first quarter of 2003 and ended a string of four
consecutive quarters of more substantial gains. Year to date, the Fund rose
5.04%, compared to a 6.76% increase for the Russell 2000 Index and a 7.83%
increase for the Russell 2000 Value Index.

We are disappointed by the results generated by the Fund during the second
quarter. The smallest and riskiest stocks, which had been the strongest
performing segment of the small cap market throughout most of 2003 and early
2004, were the poorest performing stocks during the second quarter. In this
environment, we would have expected that the Fund, which consists of larger,
higher quality companies, would have performed well relative to its benchmarks.
However, earnings disappointments among a handful of stocks that carried
relatively heavy weightings in the Fund detracted from performance during the
quarter.

MARKET REVIEW

Stocks posted modest gains during the second quarter, as indicated by a gain of
0.47% for the Russell 2000 Index, a 0.85% increase for the Russell 2000 Value
Index and a 1.72% increase for the S&P 500 Index. For the first six months of
the year, the Russell 2000 Index increased 6.76%, the Russell 2000 Value Index
was up 7.83%, and the S&P 500 Index rose 3.44%.

A surprisingly strong employment report on April 2, combined with subtle changes
in the language the Fed used to communicate its intentions with regards to
future rate increases, led to an increase in interest rates during the second
quarter. The yield on the 10-Year Treasury Bond, which rose from 3.53% on June
30, 2003, to 3.90% on April 1, 2004, increased sharply after the employment
report and ended the second quarter at 4.62%. On the last day of the quarter,
the Federal Open Market Committee announced that it was raising its target for
the Fed Funds rate by 25 basis points to 1 1/4%, confirming investor
expectations. Equity markets, which had risen steadily the previous four
quarters, stalled in the second quarter in response to the increase in interest
rates as investors were forced to focus on the potential impact those higher
rates might have on economic activity and stock price valuations.

For the first time in five quarters, small cap stocks underperformed large cap
stocks during the second quarter, as indicated by the Russell 2000 Index's 0.47%
gain compared to the 1.72% gain for the S&P 500 Index. Despite the
outperformance of large cap stocks during the second quarter, year to date,
small cap stocks have performed better, as indicated by the Russell 2000 Index's
6.76% gain compared to the

                                        1
<Page>

3.44% gain posted by the S&P 500 Index. The strong performance of small cap
stocks relative to large cap stocks since March 2000 has eliminated the enormous
valuation disparity that existed between large and small stocks at that time.
Although a return to extreme disparity in relative valuations cannot be ruled
out, it is our belief that differences in performance between small and large
stocks will be more dependent on which group delivers better earnings results.

In terms of sector performance, energy-related and industrial sectors performed
best in the Russell 2000 Value Index during the second quarter. Energy-related
stocks benefited from higher oil and gas prices. In early May, for the first
time in 13 years, oil prices, driven by strong demand and concerns about supply
disruptions, exceeded $40 per barrel. The producer durables, autos and
transportation, and materials and processing sectors all performed well during
the second quarter in response to the continuing rebound in the industrial
portion of the economy. Technology stocks were the worst performing sector of
the Index during the second quarter, as investors tempered their growth
expectations for the sector. The Index's health care stocks also performed
poorly during the quarter, as biotech and pharmaceutical stocks gave back some
of their recent strong gains. The financial services and utilities sectors,
which were among the weaker performers during the quarter, were negatively
impacted by higher interest rates. On a year-to-date basis, sector performance
was similar to the second quarter, with the exceptions being consumer
discretionary and health care, both of which performed much better in the first
quarter than second quarter, and autos and transportation, which rebounded in
the second quarter after a weak first quarter.

PORTFOLIO REVIEW

The Fund's sector weightings did not have a significant impact on overall
portfolio performance relative to the Russell 2000 Value Index. On the positive
side, the Fund was overweighted in the strong performing producer durables and
materials and processing sectors, while underweighted in the poorer performing
financial services and utilities sectors. On the negative side, the Fund was
underweighted in the top performing energy sector, while overweighted in the
poorer performing health care and technology sectors.

The Fund trailed the Indexes during the quarter primarily due to stock
selection. In particular, the poor performance of a handful of stocks that were
heavily weighted in the Fund detracted from performance. For the most part,
these stocks suffered from weaker than expected fundamentals. The impact was
felt most severely in the consumer discretionary sector, where earnings
disappointments reported by four companies with relatively high weightings led
to a 7.7% decline for the sector during the quarter compared to a 0.8% gain for
the corresponding sector of the Russell 2000 Value Index. Three of those four
stocks were home-furnishings related, an area of the market that was
exceptionally weak. On a more positive note, five of the top ten performing
stocks during the quarter were in the producer durables sector, which helped
lead that sector of the Fund to a 13.3% gain compared to a 6.2% rise for the
corresponding sector of the Index.

On a year-to-date basis, sector performance was similar to the second quarter.
The underperformance of the Fund was due primarily to stock selection rather
than sector weightings. As was the case in the second quarter, producer durables
stocks contributed the most to the Fund's relative performance during the first
six months of the year, while consumer discretionary stocks detracted the most.

OUTLOOK

Over the last five years, we have witnessed and reported on major imbalances in
the financial markets. We believed that the significantly higher valuations
awarded growth stocks compared to value stocks and large cap stocks compared to
small cap stocks in the 1998 to early 2000 time frame were unsustainable. More
recently, we commented on the potential for extremely attractive returns for
equity investors, particularly when compared to those available to holders of
fixed-income securities. Those imbalances created an enormous opportunity for
the Fund on both an absolute and relative basis. In fact, from March 1, 2000
through June 30, 2004, the Fund rose 103.38% versus an 8.38% return for the
Russell 2000 Index, an 89.02% return for the Russell 2000 Value Index, a 36.88%
loss for the Russell 2000 Growth Index, and a 10.94% loss for the S&P 500 Index.

The current market environment appears to us to be much more in balance than it
has been in some time. There does not appear to be great disparities in
valuations between large and small stocks or growth and value stocks. Overall
equity valuations appear reasonable given the level of interest rates. If our
optimism on the outlook for earnings growth proves correct, stock prices should
benefit. However, the economic environment necessary for sustained earnings
growth will likely lead to rising interest rates, which in turn may limit P/E
multiple expansion. In this environment, individual stock selection will be
critical. We are confident that we have the resources to successfully identify
the best opportunities.

STOCK HIGHLIGHTS(3)

BENCHMARK ELECTRONICS, INC. (BHE)

Benchmark Electronics, Inc. is a provider of electronic manufacturing services
to original equipment manufacturers. BHE provides engineering, procurement,
circuit board assembly, final assembly and testing. BHE serves customers in the
computer, medical, industrial and telecommunications markets. We believe that
electronic manufacturing services is a growth industry as more and more
companies are outsourcing to companies like BHE. BHE has won numerous new
programs that should ramp into meaningful incremental revenues over the next
12-18 months. BHE's balance sheet is quite strong with almost $7.00 per share of
cash and no debt. BHE's shares trade at a reasonable mid-teens valuation after
adjusting for the net cash position and we believe that BHE will enjoy mid-teens
earnings growth over the foreseeable future.

WESTCORP INC. (WES)

Westcorp Inc. is one of the largest independent automobile finance companies
with a focus on pre-owned automobiles and more creditworthy customers. We
believe earnings will grow by more than 35% in 2004 and 15-18% over the next
several years thereafter. Earnings growth is being driven by a significant
improvement in credit quality, leading to lower credit costs. Credit quality is
improving due to an increasing percentage of originations coming from
prime/lower risk automobile loans as well as an improving economy. WES should
also benefit from higher growth rates in their newer east coast operations. In
addition, we believe that profitability will improve as the east coast
operations achieve greater economies of scale. Despite the strong earnings
growth and high returns the company is experiencing, the stock is selling at a
low P/E.

There are risks of investing in a fund that invests in stocks of small sized
companies, which tend to be more volatile and less liquid than stocks of large
cap companies. There are also risks in investing in value-oriented stocks,
including the risk that value-oriented stocks will underperform growth-oriented
stocks during some periods.

VIEWS OF SKYLINE ASSET MANAGEMENT, L.P., THE FUND'S INVESTMENT ADVISER, AT THE
TIME OF THIS REPORT. THE INVESTMENTS OF THE FUND ARE SUBJECT TO CHANGE AND

NOTES TO FINANCIAL STATEMENTS

Skyline Funds is an open-end, diversified investment management company, the
sole portfolio of which is Special Equities Portfolio (the "Fund"). The Fund
commenced public offering of its shares on April 23, 1987. Skyline Special
Equities Portfolio closed to new investors on January 30, 1997 and re-opened to
new investors on October 27, 1999. The Fund's investment adviser is Skyline
Asset Management, L.P. ("The Adviser"). The Fund seeks maximum capital
appreciation primarily through investment in common stocks that The Adviser
considers to be undervalued.

                                        1
                         SIGNIFICANT ACCOUNTING POLICIES

- -  SECURITY VALUATION - Investments are stated at value. Each equity security
traded on a securities exchange shall be valued at the last current sale price
as of the time of valuation on the exchange on which the security is principally
traded (the "principal exchange"), or lacking any current reported sale on the
principal exchange at the time of valuation, at the most recent bid quotation on
the principal exchange. Each over-the-counter security traded in the Nasdaq
Stock Market ("Nasdaq") shall be valued at the Nasdaq Official Closing Price
("NOCP"), as determined by Nasdaq, or lacking an NOCP, the last current reported
sale price as of the time of valuation on Nasdaq, or lacking any current
reported sale on Nasdaq at the time of valuation, at the most recent bid
quotation on Nasdaq. For certain fixed-income securities, Skyline Funds' Board
of Trustees has authorized the use of market valuations provided by an
independent pricing service. Short-term instruments with sixty days or less to
maturity are valued at amortized cost which approximates market value.
Securities or other assets for which market quotations are not readily
available, which may include certain restricted securities, are valued at a fair
value as determined in good faith by the Skyline Funds' Board of Trustees or a
committee thereof.

- -  SECURITY TRANSACTIONS AND INVESTMENT INCOME - Security transactions are
accounted for on the trade date (date the order to buy or sell is executed) and
dividend income is recorded on the ex-dividend date. Interest income is recorded
on an accrual basis and includes amortization of premiums and discounts.
Realized gains and losses from security transactions are reported on an
identified cost basis.

- -  FUND SHARE VALUATION - Fund shares are sold and redeemed on a continuous
basis at net asset value. Net asset value per share is determined as of the
close of regular session trading on the New York Stock Exchange (normally 3:00
p.m. Central Time), each day that the Exchange is open for trading. The net
asset value per share is determined by dividing the value of all securities and
other assets, less liabilities, by the number of shares of the Fund outstanding.

- -  FEDERAL INCOME TAXES AND DIVIDENDS TO SHAREHOLDERS - It is the Fund's policy
to comply with the special provisions of the Internal Revenue Code applicable to
regulated investment companies and, in the manner provided therein, to
distribute substantially all of its taxable income to shareholders. Such
provisions were complied

                                       18
<Page>

with and, therefore, no federal income taxes have been accrued in the
accompanying financial statements.

As of December 31, 2003 the Fund had no capital loss carryforwards.

Dividends payable to its shareholders are recorded by the Fund on the
ex-dividend date. The timing and characterization of certain income and capital
gain distributions are determined annually in accordance with Federal income tax
regulations that may differ from accounting principles generally accepted in the
United States. As a result, net investment income or loss and net realized gain
or loss for a reporting period may differ from the amount distributed during
such period. In addition, the Fund may periodically record reclassifications
among certain capital accounts to reflect differences between financial
reporting and income tax purposes. These reclassifications will be updated at
the Fund's fiscal year-end.

On December 17, 2003, a distribution of $1.55614 per share was declared. The
dividend was paid on December 19, 2003, to shareholders of record on December
18, 2003.

The tax character of distributions paid during 2003 was as follows:

<Table>
                                    
   Distributions paid from:
   Ordinary income                     $   8,393,488
   Long-term capital gain                 19,543,604
                                       -------------
                                       $  27,937,092
</Table>

Cost of investments for federal income tax purposes was substantially the same
as book cost of $438,399,190 on June 30, 2004, net unrealized appreciation was
$109,833,617, consisting of gross unrealized appreciation of $119,941,367 and
gross unrealized depreciation of $10,107,750.

- -  LINE OF CREDIT - The Fund has a $3 million committed revolving credit
facility for temporary or emergency purposes, including the meeting of
redemption requests that otherwise might require the untimely disposition of
securities. The Adviser pays a commitment fee of 10 basis points per annum of
the average daily unutilized portion of the committed line of credit not
utilized. Under the terms of the credit agreement, interest on each loan would
be fixed at the prime rate less 150 basis points. For the six month period ended
June 30, 2004, there were no loans outstanding under the credit facility.

                                       19
<Page>

- -  USE OF ESTIMATES - The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the amounts reported in
the financial statements and accompanying notes. Actual results may differ from
those estimates.

                                        2
                          TRANSACTIONS WITH AFFILIATES

For the Adviser's management and advisory services and the assumption of most of
the Fund's ordinary operating expenses, the Fund incurs a monthly comprehensive
fee based on its average daily net assets at the annual rate of 1.50% of the
first $200 million, 1.45% of the next $200 million, 1.40% of the next $200
million, and 1.35% of any excess over $600 million. The total comprehensive
management fee incurred for the period ended June 30, 2004 was $3,950,940.

Certain officers and trustees of the Skyline Funds are also officers, limited
partners or shareholders of limited partners of the Adviser. The Fund makes no
direct payments to the officers or trustees who are affiliated with the Adviser.
For the period ended June 30, 2004, the Fund incurred fees of $25,622 to its
unaffiliated trustees.

The Fund provides a deferred compensation plan for its trustees who are not
officers, limited partners or shareholders of limited partners of the Adviser.
Under the deferred compensation plan, trustees may elect to defer all or a
portion of their compensation. Amounts deferred are retained by the Fund, and to
the extent permitted by the 1940 Act, as amended, may be invested in the common
shares of the Fund, as selected by the trustees. Investments in such funds are
reflected as "Other Assets" on the Statement of Assets and Liabilities at June
30, 2004. Appreciation/depreciation and distributions received from these
investments are recorded with an offsetting increase/decrease in the deferred
compensation obligation and do not affect the net asset value of the Fund.
