Fellow Partner:

     Our Fund earned $2.13 per share of net investment income in the six months
ended June 30, 2003. Earnings in the same period of 2002 were $1.86 per share.
Dividend income continues to do well and expense accruals were lower in the
first half of 2003.

     After providing for the $0.95 per share distribution to partners of record
on June 27, 2003, the net asset value per partnership share at June 30, 2003 was
$288.88. The net asset value at March 31, 2003, our last report date, was
$261.10.

     During the second quarter of 2003, approximately 70 percent (120,000
shares) of our investment in Schering-Plough Corp. was sold at a loss of
$3,016,976. The remaining shares were sold in July 2003. The loss on this sale
was partially offset by the receipt of $624,855 which is our Fund's share of the
settlement of a suit against Cendant Corp., shares of which we owned until the
year 2000.

     Commentary on market conditions and a comparison of our Fund's performance
to the Standard & Poor's 500 Index and the Dow Jones Industrial Average will be
found in the accompanying Investment Adviser's Report.

     Your comments or questions concerning Chestnut Street Exchange Fund are

                          INVESTMENT ADVISER'S REPORT

2ND QUARTER 2003 U.S. EQUITY MARKET REVIEW

ECONOMIC REVIEW

     The second quarter of 2003 saw equity prices around the globe rally
strongly. In the U.S., the S&P 500 Index returned 15.4%, its largest quarterly
gain since the fourth quarter of 1998. Other domestic equity indexes also
performed well, with the Dow Jones Industrial Average returning 13.1%, its
biggest gain since the fourth quarter of 2001, and the NASDAQ Composite Index
climbing 21.1%, thanks in large part to its heavy weighting in technology
stocks, which soared during the period. Small cap stocks in the U.S. also
benefited from the improving investor sentiment as the Russell 2000 Index gained
over 23% for the quarter.

     Several of the factors that hampered stocks in the first quarter unwound in
the second: the war in Iraq came to a swift conclusion, weather patterns in the
Northeast normalized, the hysteria over the SARS epidemic subsided, corporate
profits were generally better than expected and the economy finally began to
show signs of improvement.

     With the announcement in April of the conclusion of major combat in Iraq,
investors turned their attention from geopolitical issues to the domestic
economy and corporate earnings and, for the first time since the fourth quarter
of 2001, there were enough positive signs to cause a significant change in
sentiment. On the economic front, the situation is improving gradually. In the
first quarter, GDP growth was a paltry 1.4% and it appears as if the second
quarter figures will come in at the same level or below. Towards the end of the
quarter, however, several other economic indicators, including consumer
confidence and personal income and spending showed healthy improvement. The
housing market also remained strong, due to favorable mortgage rates, which are
currently at 45-year lows. New home sales were at an all time record in May
while existing home sales also remained near record highs. The news on
manufacturing, however, was less encouraging. The Institute for Supply
Management's (ISM) index of U.S. manufacturing activity, despite coming in
higher than expected in May, showed that manufacturing contracted for a third
consecutive month. Other signs of weakness included soft durable goods orders
and industrial production and stubbornly high unemployment and weekly jobless
claims.

     Despite some signs of improvement, the economy is clearly mired in a slump.
The Federal Reserve has proven to be unwilling to wait passively for signs of a
pick-up before acting to boost activity. Given the Fed's emphasis on the risks
of deflation in its May 6th statement and the consistently dovish commentary
emanating from committee members, investors widely anticipated the June 25th
rate cut. However, the expected magnitude of the cut, as well as the form of Fed
action (rate cuts versus open market bond purchases), was hotly debated. In the
end, the Fed voted to cut the Fed Funds target by 0.25%, which disappointed the
bond market but indicated to equity investors that there is reasonable hope for
a second half economic recovery. Fiscal policy has also been stimulative with
the Federal government running significant deficits and Congress enacting a
substantial tax cut that took effect July 1st. In addition to these factors, the
dollar's continued decline versus other currencies, particularly the Euro,
should help to stimulate export activity for U.S. companies and has already
provided a lift to profits for U.S. based multinationals.

     Corporate earnings took a back seat to geopolitical events during most of
the first quarter, but have since come back into focus. According to First Call,
first quarter reported earnings for S&P 500 constituents came in at $12.55 per
share for an 11.5% gain over the first quarter of 2002. While this

                                        2


appeared encouraging on the surface, and was ahead of expectations, a closer
look revealed that the earnings gains came from a combination of continued cost
cutting, the weaker U.S. dollar and easy comparisons rather than sales growth,
which was disappointing. The weaker dollar helps U.S. multinationals through
currency translation gains but these are not normally paid for with stock gains,
as they tend to be transitory. On the other hand, the weaker dollar clearly
benefits U.S. companies in terms of global competitiveness. At this point, First
Call indicates that S&P 500 companies' average earnings are expected to be up 4%
for the second quarter and 8% for the entire year. These estimates may be too
low based on the low level of negative "pre-announcements" to date and the
expected pick-up in economic activity in the second half of the year.

MARKET REVIEW

     Small cap stocks outperformed large cap stocks for the quarter with the
Russell 2000 Index of small cap stocks returning 23.4%, while the large cap
Russell 1000 Index returned 15.7%. In the large cap market, value stocks
outperformed growth stocks for the quarter with the Russell 1000 Value Index
gaining 17.3% while the Russell 1000 Growth Index returned 14.3%. In the small
cap arena, growth stocks modestly outperformed value stocks with the Russell
2000 Growth Index rising 24.1% while the Russell 2000 Value Index gained 22.7%.

     In the large cap segment of the market, every economic sector managed a
positive return for the quarter. The traditionally defensive sectors lagged in
the quarter as investors began to believe that economic activity would finally
start to respond to the flood of stimulus. Reversing last quarter's terrible
performance, telecomm stocks rallied strongly and finished up 20.4%. Not far
behind were utilities (+20.1%), consumer discretionary (+18.8%), technology
(+18.1%) and financials (+17.8%). Among the underperforming sectors were
healthcare (+9.5%), consumer staples (+8.5%) and energy (+6.4%) as the stable,
predictable earnings of these companies became less appealing to investors than
stocks with greater earnings leverage in an improving economy. In the small cap
segment, every sector in the small cap index posted double-digit gains in the
quarter with the exception of the relatively small, integrated oil group, which
fell 1.8%.

OUTLOOK

     The rally in equity prices that began in mid-March has been largely fueled
by liquidity. Investor confidence has grown driven partially by the belief that
there are enough stimuli in the economy to spur growth and the belief that the
Fed will stay on hold as it guards against deflation. As a result, money has
been flowing back into equity mutual funds and some investor sentiment indexes
have moved back to very bullish levels. Institutional investors have likewise
been adding to equities as they search for higher returns than those offered by
money funds and bonds, whose yields have dropped to historically low levels.

     We are unenthusiastic about the direction of the U.S. equity markets from
these levels based on current fundamentals. In short, we do not believe
corporate profits will increase enough in the near future to justify the recent
gains in equity prices. We also remain concerned about whether or not U.S.
consumers will continue spending long enough to support the economy until a
corporate spending cycle emerges, despite the record levels of mortgage
refinancings, which continue to provide consumers with access to cash. Capital
spending remains very weak and it's difficult to see when a significant pick-up
will begin as most industrial companies continue to see a difficult earnings
environment. That being said, we do acknowledge that liquidity driven rallies
can continue for long periods of time, stretching valuations beyond reasonable
levels

PORTFOLIO REVIEW

     During the second quarter, the Fund underperformed the broad market by 4.4%
with a return of 11.0% compared to the S&P 500 Index, which returned 15.4%. Year
to date, the Fund has returned 10.1% versus 11.8% for the S&P 500. Stocks with
the most significant positive contribution to performance included Intel, Bank
of America, and JP Morgan. Johnson and Johnson and 3M had the most significant
negative effect in dollar terms, and were the only two stocks with negative
returns for the period.

     A significant portion of the Fund's underperformance for the quarter
resulted from the portfolio's structure rather than from security specific
issues. During the quarter, the stocks that performed the best were the names
that have been exhibiting the highest degree of volatility over the past several
quarters. In addition, smaller cap stocks generally outperformed larger stocks
within most benchmarks. Evidence of these trends can be seen in the significant
bounce in the prices of numerous stocks that had been severely depressed during
the bear market. The Fund typically has very little exposure to higher
volatility stocks, opting instead for stocks with more stable price histories,
and is also typically concentrated in large cap companies. However, rotational
trends such as this, where depressed, volatile stocks significantly outperform,
typically do not last long so we would not expect to be negatively impacted by
these factors for a sustained period of time.

     On a stock specific basis, Johnson and Johnson fell 10.7% during the
quarter, significantly underperforming the market and the drug group.
Approximately one half of the drop occurred immediately following the company's
earnings release in mid-April. There were no major misses relative to
expectations as JNJ announced a 13% increase in earnings on a quarterly sales
increase of 12% (8.1% excluding currency translation), however, investors were
somewhat disappointed with the slowing growth in Procrit and the European
version of the drug called Eprex. Increased competition, as well as reports that
the drug has been linked to a rare blood disorder in some European patients,
caused the company to trim growth forecasts for the drug over the next several
quarters. The stock also struggled in May and June as the company faced
inventory shortages in the new Cypher drug-eluting stent, which hit the market
in great demand. Analysts have worried that production issues will result in
less robust results for the stent and that missteps could allow competition to
gain ground more quickly than anticipated. We viewed the stock as highly valued
based on the attention the new stent product generated but with the recent
weakness we have been hesitant to trim the position. We anticipate reducing the
size of the position in the portfolio on future price strength.

     3M performed very well in the early part of the year, appreciating to
roughly $135 by early April on positive fundamental improvements in the business
resulting from several new initiatives put in place by the company's CEO, James
McNerny. In April, 3M announced first quarter results that were in line with
estimates and showed an 11% revenue increase and 15% earnings growth. The
company also issued earnings guidance for the remainder of the year of $1.47 to
$1.53 per share while consensus estimates call for $1.50. Subsequently, several
analysts downgraded near-term ratings based on the significant boost in sales
related to the weaker dollar, the muted near term economic growth forecasts and
continued asbestos liability risk. As a result, the stock traded off to
approximately $120, but has since rebounded.

     On the positive side, Intel rallied strongly in the quarter, returning 28%.
With the stock accounting for approximately 14% of the portfolio's value, it had
the largest impact on the Fund's return by a wide margin. In general, Intel's
business seems to have turned the corner with estimates of future earnings
stabilizing. Intel's first quarter earnings were flat compared to last year and
the company indicated that

                                        4


the outlook for the remainder of the year would be modestly positive. Although
the situation has improved, we continue to believe that Intel faces a difficult
road given the technology capital spending environment. Earnings estimates for
2004 have come down modestly but still discount a 31% growth rate from this
year. With a P/E ratio of 46x last year's earnings and 28x 2004 earnings, we
believe that the risk outweighs the potential reward in the stock given its very
large size in the portfolio.

     Financial stocks, and banks in particular, performed modestly better than
the S&P 500 Index for the quarter. Within the Fund, JP Morgan and Bank of
America performed well. These positions advanced steadily throughout the quarter
off of depressed valuations as investors moved back into financial stocks to
participate in the market's move. Bank of America gained 18% and, as one of the
larger positions in the Fund, it had a strong positive effect on returns. JP
Morgan was the single best performing stock in the Fund for the quarter,
rallying 44%, but it's impact on performance was limited given its relatively
small position (2%) in the portfolio. JP Morgan's first quarter earnings were
ahead of expectations and analysts are expecting a strong earnings rebound from
2002's depressed levels.

(A) Chestnut Street Exchange Fund (the "Fund") is registered under the
    Investment Company Act of 1940, as amended, as a diversified open-end
    management company. The Fund's investment objective is to seek long-term
    growth of capital and, secondarily, current income. Significant accounting
    policies are as follows: Investments are stated at value in the accompanying
    financial statements. Securities listed on a securities exchange are valued
    at the close of trading on June 30, 2003. Securities not so listed or not
    traded on that date are valued at the latest bid price. Short-term
    obligations are valued at amortized cost which approximates market. Security
    transactions are accounted for on the trade date. The cost of investments
    sold or redeemed in kind is determined by the use of the specific
    identification method for both financial reporting and income tax purposes.
    For securities received in the Exchange at inception of the Fund in 1976,
    cost for financial reporting purposes is the value of the securities as used
    in the Exchange and for income tax purposes, the tax basis of the individual
    investor. Interest income is recorded on an accrual basis; dividend income
    is recorded on the ex-dividend date. It is the Fund's policy to continue to
    comply with the requirements of the Internal Revenue Code applicable to
    regulated investment companies and to make the requisite distribution of
    taxable investment income and capital gains to its shareholders which will
    relieve it from all or substantially all federal income and excise taxes.

    The preparation of financial statements in conformity with generally
    accepted principles requires management to make estimates and assumptions
    that affect the reported amounts of 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 these
    estimates.

(B) Effective January 1,1998, the Fund changed its tax status from a partnership
    to a regulated investment company. The change results from the enactment of
    the "Publicly Traded Partnership" rules to the Internal Revenue Code in
    1987, which first applied to the Fund after 1997. Commencing in 1998, the
    Fund will not distribute net long-term capital gains, but will retain the
    gains and pay the applicable corporate income tax rate. On the last day of
    the year, the partners are entitled to a proportionate credit of the tax
    payment and the tax basis of their shares is increased by the amount of
    undistributed gains less the tax paid by the Fund. The Fund had no net
    realized long-term capital gains in the six months ended June 30, 2003.

(C) PNC Bank and BlackRock Institutional Management Corporation ("BIMC"), a
    majority-owned subsidiary of PNC Bank, are co-investment advisers to the
    Fund pursuant to an Advisory Agreement dated January 1, 1998. In June 1998,
    PNC Bank and BIMC restructured their operations and BlackRock Financial
    Management, Inc. ("BFM"), a majority-owned subsidiary of PNC Bank, assumed
    the rights and obligations of PNC Bank under the Advisory Agreement. The
    Fund pays BIMC an investment advisory fee for the services of BIMC and BFM.

    The Advisory Agreement provides for a fee at the annual rate of 4/10ths of
    1% of the first $100,000,000 of the Fund's average daily net assets plus
    3/10ths of 1% of net assets exceeding $100,000,000.

    The managing general partners each receive a fixed fee as compensation for
    their services. PFPC Inc., an affiliate of PNC Bank, is the Fund's transfer
    agent. PFPC Trust Company, a subsidiary of PFPC Inc., is the Fund's
    custodian.

                                        11


(D) Purchases and sales of investment securities (excluding short-term
    obligations) were $0 and $2,207,524, respectively, for the six months ended
    June 30, 2003.

    During the year 2002, the Fund realized a loss of $2,288,260 on sale of
    securities. This loss may be carried forward up to eight years to reduce the
    tax effect of future gains on sales of securities. This loss will expire in
    2010.

(E) At June 30, 2003, net assets consisted of:
